American Single Malt Whiskey FAQ

A complete guide

The Macklowe Whiskey is made only using 100% malted barley.

The whiskey is mashed, distilled, and matured in the USA, using oak casks not exceeding 700 liters in capacity. It is distilled to a maximum of 160 (U.S.) proof (80% alcohol by volume) and bottled at 80 (U.S.) proof or higher (40% alcohol by volume).

Is it Whisky or Whiskey?

Tracing whisky’s roots back to Scotland and Ireland, the original names for water of life, “uisge beatha” and “uisce beatha” respectively, were remarkably similar. As the Gaelic languages were Anglicized, the phrase was eventually shortened to simply the word for water: “whisky” in Scotland and “whiskey” in Ireland.

The Irish immigrants who traveled to the new world brought not only the knowledge of how to make whiskey with them, they also brought their spelling. For the rest of the world, and many American distilleries who trace their roots back to Scotland or intended to maintain a more global spelling, whisky is their spelling of choice.

In a nod to a more universal spelling and for simplicity’s sake, this guide will use whisky as the spelling for all instances apart from specific brand names. While Ireland and many American distilleries include an “e” in their spelling, even Maker’s Mark, George Dickel, Old Forester and Balcones are among the ranks of those who leave out the “e.”

How whiskey is made?

Before jumping into what makes a whisky an American single malt, let’s cover our bases and do a whisky 101 overview. Simply defined, whisky is an alcoholic product made for consumption that’s at least 40% alcohol by volume (ABV) created by distilling fermented grain mash. Only three ingredients are needed to produce whisky: yeast, water, and grain.

Sounds easy, right?

But ask any distiller what it takes to make whisky: chances are they’ll tell you producing whisky is one part art and another part science. Think about it for a second: to turn these three ingredients into a spirit that has a complex array of aromas and flavors is quite the feat.

There are many factors that go into producing the variety of tastes of whiskies you enjoy: from the type of grain used, the yeast profile, and the water, but also various distillation techniques, equipment used, barrel aging and finishing techniques, how the whisky is married before bottling, and the timing of each and every process. That’s why if you pour yourself five different whiskies produced by five different distilleries, they’ll all have unique tastes.

The four grains most commonly used for whisky production are corn, rye, wheat and barley. Each grain produces a whisky with different taste. As an example, whisky produced using corn will taste sweeter compared to a whisky produced using rye, which generally takes on a more spicy profile.

There are slight differences in the process of producing whisky depending on the grain used, but in general, the process of creating whisky is as follows:

MALTING. The process in which the grain is moistened, allowing it to germinate, and then heated and dried to stop its malting process.

MILLING. The process in which the malted grains are ground up into three parts – the husks, the middle, and the flour – that creates a powdery composition known as the grist.

MASHING. The process in which the grist is combined with water of varying hot temperatures in a large container called a mash tun, producing mash or wort.

FERMENTATION. The process in which yeast is added to the mash (or wort if the spent grains are removed first), converting sugar in the mash to alcohol, producing unhopped beer of approximately 8% alcohol by volume, known as the wash.

DISTILLATION. The process in which the wash is heated up in a still, where the alcohol is separated and removed from the wash, creating the spirit that will be placed into casks to mature and become whisky.

MATURATION. The distilled spirit is placed in a variety of oak barrels and matures for a certain length of time, where it takes on its flavor and color profiles.

VATTING. After maturation, whiskies from different casks may be combined and given a water addition, both of which can add to the whisky’s characteristics and final taste.

BOTTLING. The whisky is finally put into bottles at or above 40% ABV for your consumption.

DEFINING AMERICAN SINGLE MALT WHISKEY

Like many other spirits, whisky and its varying subcategories are often defined by laws of the nations where it’s produced. The differences in definitions include minimum aging requirements and naming standards, to name a few.

To define what American single malt whisky is, let’s break down each word, working backwards starting with ‘whisky’.

WHISKY

In summary, whisky is an alcoholic beverage made from distilling fermented grain mash that’s at least 40% ABV. Worldwide, this is a fairly agreed upon standard.

MALT WHISKY

To classify what defines a malt whisky, it depends on the country where the whisky is produced:

In Scotland and Ireland, for a whisky to be called a malt whisky, the spirit must be produced using 100% malted barley.
In the United States however, according to the Standards of Identity for Distilled Spirits, a spirit defined as a malt whisky must be produced using a mash bill of at least 51% malted barley.

SINGLE MALT WHISKY

To classify as a single malt whisky, it’s generally accepted that the whisky must be produced at a single distillery.

According to the Scotch Whisky Regulations 2009, Single Malt Scotch Whisky is defined as a whisky with a mash bill consisting of 100% malted barley, produced from only water and malted barley at a single distillery by batch distillation in pot stills.

In the United States, there’s a general agreement that a Single Malt Whisky follows in the footsteps of the regulations of Scotland, where the whisky must be 100% malted barley produced at a single distillery. However, there are no laws and regulations in place that prevent a distillery in the United States from calling their product a “Single Malt Whisky” if what’s being produced is produced using a mash bill of 51% barley.

AMERICAN SINGLE MALT WHISKY

Lastly, for a whisky to be classified as an American single malt whisky, there’s a general agreement that the whisky is produced from 100% malted barley, at a single distillery, in the United States.

But again, there are no laws and regulations in place that prevent a distillery from putting the words ‘American Single Malt Whisky’ on their bottle. Therefore, if a distillery in the U.S. releases a whisky that was distilled in two locations and has a mash bill of 70% malted barley and 30% wheat, they could still label their product “American Single Malt Whisky”.

In the United States Code of Federal Regulations, the Standards of Identity for Distilled Spirits define a malt whisky, recognizing it as a whisky with a mash bill of at least 51% malted barley, but don’t officially define American single malt whisky.

There’s a general agreement in place amongst distilleries in the United States of what defines a whisky to be classified as an American single malt. However, it’s not regulated at the moment.

Confusing, right? That’s where the American Single Malt Whiskey Commission steps in.

THE IMPORTANCE OF THE AMERICAN SINGLE MALT WHISKEY COMMISSION

Bourbon whisky is held to a strict definition by a document called The Federal Standards of Identity for Distilled Spirits. Trade agreements between the United States and other countries help maintain that standard of Bourbon, reserving the term Bourbon for products made in the United States.

Similarly, Scotch is held to strict standards by a document called The Scotch Whisky Regulations 2009. In order for a distillery to call their product Scotch, distilleries in Scotland must follow the guidelines outlined in this document. This document also outlines various Scotch subcategories such as Single Malt Scotch Whisky and Blended Malt Scotch Whisky to name a few.

But when it comes to American single malt whisky, there are no identity standards. The American Single Malt Whiskey Commission was formed in 2016 to try to make that happen. From their website:

The American Single Malt Whiskey Commission serves to establish, promote and protect the category of American Single Malt Whiskey.

The American Single Malt Whiskey Commission (ASMWC) has been formed in response to the growing need for American-based producers to define the category—both domestically and internationally—in order to protect, educate, promote and ultimately grow it.

Thus, the commission defines American single malt whisky by the following six guidelines:

Made from 100% malted barley
Distilled entirely at one distillery
Mashed, distilled, and matured in the United States
Matured in oak casks of a capacity not exceeding 700 liters
Distilled to no more than 160 proof (80% ABV)
Bottled greater than 80 proof (40% ABV)

The ASMWC consists of 16 founding distilleries and over 130 members. If they’re successful in securing a formal standard of identity that’s ultimately protected by law in a similar fashion to how Bourbon and Scotch is protected, it will go a long way to help establish and grow the American single malt whisky category.

THE DOWNSIDES OF NOT HAVING A RECOGNIZED STANDARD OF IDENTITY

We’ve talked about Scotch and Bourbon. Let’s talk about Japanese whisky.

Japanese whisky is currently in such high demand that Japanese distilleries are having a hard time keeping pace. Maybe that’s because Japanese whiskies have such a unique history and flavor profile in relation to other whiskies produced around the world. Or maybe you can also argue that it’s Bill Murray’s fault.

It’s a fast-growing niche, and to keep up with the demand, some distilleries are increasing the prices of their offerings, sometimes as high as 100%. Popular Japanese whisky brands include Suntory, Nikka, Yamazaki, and Hibiki to name a few.

But others see the high demand for Japanese whisky strictly as a business opportunity by importing whisky from other locations around the world, maturing, finishing, and bottling the whisky in Japan for a minimal amount of time, and then turning around and selling the whisky at an exaggerated price, knowing that they can label their offering as Japanese whisky.

This loophole is made possible because there isn’t a recognized standard of identity for Japanese whisky. Unless you’re a well-researched consumer, you could be paying top dollar for a bottle of Japanese whisky that in all fairness might not be considered Japanese whisky by many standards.

Having a standard of identity would both protect consumers and producers of whisky alike in this case, so that when a bottle of Japanese whisky is produced and sold, you know what you’re buying. The ASMWC formed with the intention of getting ahead of this exact issue happening in the United States.

SCOTCH WHISKY VS. AMERICAN SINGLE MALT

How does American single malt whisky compare to Scotch Whisky? It’s a question commonly asked at tastings while educating those interested in the American single malt category.

WHAT IS SCOTCH WHISKY?

Learn about the official documents that define Scotch, The Scotch Whisky Regulations 2009. Feel free to read this 83-page PDF, but for a cliff note version, Scotch can be generalized by the following seven rules:

Made from water, malted barley, and yeast
Distilled to no more than 94.8% ABV
Matured in oak casks of a capacity not exceeding 700 liters
Mashed, distilled, and matured in Scotland
Matured for more a minimum of 3 years in an excise warehouse or a permitted place
No substance added except water and plain caramel coloring
Bottled at or greater than 80 proof (40% ABV)

Scotch Whisky also has a number of subcategories, with the two popular subcategories being Single Malt Scotch Whisky and Blended Scotch Whisky.

Single Malt Scotch Whisky is defined as a single malt whisky from Scotland produced at one distillery using 100% malted barley. Many iconic Scotch brands are single malt producers, including The Balvenie, Bruichladdich, The Dalmore, Glenfiddich, The Glenlivet, Glenmorangie, Highland Park, Laphroaig, The Macallan, and Talisker to name a few.

Blended Scotch Whisky is defined as a whisky combining one or more grain whiskies with one or more malt whiskies. Many iconic Scotch brands are blended Scotch producers, including Ballantine’s, Chivas Regal, Dewars, The Famous Grouse, Johnnie Walker, Whyte & Mackay, and William Grant & Sons. Blended Scotch is a huge industry: 90% of the final whisky produced in Scotland is classified as Blended Scotch Whisky.

Other subcategories of Scotch include Blended Malt Scotch Whisky (formerly known as “vatted”, containing a combination of only malt whiskies from different distilleries), Single Grain Scotch Whisky, and Blended Grain Scotch Whisky.

Scotch is a classic example of a product that’s well-known internationally. When you think of Scotland, you might think of the Loch Ness monster, bagpipes, and Scotch. Needless to say, Scotch is a huge export of Scotland and a significant part of Scotland’s economy. That’s why it’s very important for them to protect the definition of Scotch.

SIMILARITIES & DIFFERENCES OF SCOTCH AND AMERICAN SINGLE MALT WHISKY

The subcategory of Scotch that most closely matches the proposed definition of American single malt whisky category is Single Malt Scotch Whisky. Both products come from a single distillery using 100% malted barley. The process of distillation and maturation are often very similar. Cask types used in Scotch and American single malt whisky often include ex-Bourbon casks, but can also include a variety of others, such as sherry, port, and wine casks.

As there are Scotch brands that are world-famous for their peated whiskies, Scotch is sometimes associated with peat. Several well-known peated Scotch producers include Laphroaig, Lagavulin, Talisker, and Bruichladdich.

However, it’s a misconception that all Scotch is peated, and that peated expressions are only found in Scotch. It’s true that a handful of Scotch brands are world-famous for their peated expressions, but not all Scotch is peated by a long shot.

Alternatively, there are instances of peated American single malt whiskies: Westland Distillery’s Peated American Single Malt Whiskey and Sante Fe Spirits ’ Colkegan Single Malt Whiskey (mesquite-smoked whiskey), are standout expressions. But peated American single malts aren’t nearly as popular and widespread as peated Scotch Whiskies.

Another difference between Scotch Whisky and American single malt is age statements. It’s very common to see an age statement on a bottle of Scotch that tells you how old the whiskey is inside the bottle. Glenfiddich 12, Lagavulin 16, and Glendronach 18 refer to whiskies that are 12, 16, and 18 years old respectively.

In the American single malt category, age statements aren’t that common for two main reasons. First, the climate of the United States is much different than Scotland. The temperature ranges from season to season are much more dramatic in the United States than found in Scotland. As a generalization, this difference in climate allows whisky in the United States to mature more quickly.

Second, it’s a matter of timing. American single malt whisky is still a new category. You’re not going to often find whisky that has a 10+ year age statement simply because many of the American single malt producers in the United States started after 2010.

To comply with TTB standards (Alcohol and Tobacco Tax and Trade Bureau), you will see some American single malt products adding age statements that might contain whisky matured less than 4 years.

It’s a common misconception that the longer the whisky matures in a cask, the better it is. Learn more in the ‘Pertaining to Age Statements’.

A TASTE COMPARISON OF SCOTCH AND AMERICAN SINGLE MALT WHISKY

Scotch and American single malt may be similar in makeup, though there are a wider range of Scotch products available in relation to American single malt products. Scotch Whisky identity extends to five (six, if you separate the islands) specific regions, which are noted for distinct styles: the Lowlands, the Highlands, Campbeltown, Speyside and Islay.

The Lowland’s smooth malts offer lighter notes of grass, honeysuckle, toffee and cinnamon.
The Highland region, which generally includes the islands apart from Islay and formerly held Speyside, showcases a range of lighter whiskies all the way through salty coastal malts.
Campbeltown whiskies are typically robust and flavorful. Fruit, vanilla and toffee notes are often accentuated with a hint of salt and smoke.
Speyside is Scotland’s most densely populated region of distilleries, with whiskies known for moderate to zero peat. Typical expressions showcase soft caramel, fruits, vanilla and spice.
Windswept Islay’s whiskies are recognized the world over for the influence of peat, even though many of Islay’s distilleries obtain their malt from other regions of Scotland.

These geographically focused designations have yet to be set in the United States, even though the geography and climate in the United States is more diverse than what can be found in the United Kingdom. American single malt producers have been able to showcase a wide array of styles thanks largely to dramatic temperature swings, humidity impacts and a unique selection of aging techniques.

American single malt distilleries such as Texas’s Balcones Distilling highlight the shorter aging time needed thanks to their intense, hot summers. West coast single malt producers like Washington state’s Westland Distillery have been known to utilize unique regional elements such as peat or region specific wood for their barrels. At Virginia Distillery Company, we’ve been tracking seasonal climate impacts on barrel aging in Virginia’s humid, subtropical climate. These distinctive production elements contribute to a concept of provenance that makes its way into the whisky’s aromas and taste.

Many American single malt distilleries have been known to utilize new oak, in contrast to the used oak favored by Scottish distilleries. Some American single malt producers, such as Tuthilltown Spirits’ Hudson Single Malt age their whisky in small American Oak barrels to further decrease aging time and significantly play up the new oak wood notes in their whisky, a striking contrast to Scottish single malts.

BOURBON WHISKEY VS. AMERICAN SINGLE MALT

How does American single malt whiskey compare to Bourbon whiskey? Due to the popularity of Bourbon in the United States, this is a question often asked at tastings while educating consumers on the American single malt category.

WHAT IS BOURBON WHISKEY?

Similar to Scotch and The Scotch Whisky Regulations 2009, the United States has official documents that define Bourbon called The Federal Standards of Identity for Distilled Spirits (27 CFR 5). For a cliff note version, Bourbon can be generalized by the following nine rules:

The grain mixture (mash bill) must be at least 51% corn
Distilled to no more than 80% ABV (160 proof)
Matured in new, charred oak barrels
The entry proof cannot be greater than 62.5% ABV (125 proof)
Bottled greater than 80 proof (40% ABV)
Must be produced in the United States (not just Kentucky)
If it’s aged for a minimum of two years, it qualifies as Straight Bourbon
An age statement must be produced on the bottle if it has been aged for less than 4 years
If there’s an age statement produced on the bottle, it must be the age of the youngest whisky in the bottle

“I like Bourbon a lot, but I’m not a huge fan of whisky” is something we hear repeated out in the field more often than you think. It’s a testament of how popular bourbon has become. To clarify, bourbon is a type of whisky, not the other way around.

Bourbon is a distinctive product of the United States, sometimes nicknamed ‘America’s Native Spirit’. You might know it as the drink your father or grandfather would have to wind down their day. Bourbon is a big deal in the United States; its rich history and legacy arguably had a large part in shaping America as it is today.

Bourbon is aligned to Scotch in a similar manner in that if a Canadian distillery produced a product that met all the Bourbon standards of identity outlined above, it would still have to be labeled something else other than Bourbon since it’s not made in the US. It would be enforced per the United States and Canada trade agreements in place.

SIMILARITIES & DIFFERENCES OF BOURBON AND AMERICAN SINGLE MALT WHISKEY

Bourbon and American Single Malt Whisky are both great whiskies served neat or on the rocks. They’re both close to the same strength with a minimum of 40% ABV and both matured in oak barrels.

But there are some differences. Bourbon has a mash bill of at least 51% corn and must be matured in new, charred oak barrels. American single malt is 100% malted barley and can be matured in used oak barrels, sometimes ex-Bourbon barrels, sometimes different barrels altogether or new oak casks.

Bourbon production is concentrated: 95% of Bourbon is produced in Kentucky and is popular as a southern spirit. American Single Malt Whisky is much more widespread, produced in distilleries from Massachusetts, to California, and everywhere in between.

A TASTE COMPARISON OF BOURBON AND AMERICAN SINGLE MALT WHISKY

The base ingredients and the methods of production and aging dictate that there will be several key differences in the taste of Bourbon vs. American single malt.

Bourbon’s dominant grain, corn, is loaded with starch and will contribute a sweetness due to the amount of sugar that can be extracted from each kernel of corn. The addition of wheat or rye into a Bourbon’s mash bill will add notes of soft fruit and floral spice respectively. Bourbon is also made using a sour mash process and even the fermentation and shape of the stills (commonly column or hybrid), will impact the amount of congeners and thus flavors in a Bourbon. Aging in new charred oak means notes of vanilla, cherry, barrel spice and tannin are common notes found in Bourbon.

American single malt is made with 100% malted barley, which contributes both fruity and nutty character to a whisky. The aromatics of barley are typically complex and soft, and the mouthfeel contributed to barley will often be round. With many American single malts distilled in copper pot stills, the unique reflux patterns will result in a character-driven spirit.

Where Bourbons are restricted to aging in new charred oak, American single malts have the freedom to capitalize on the gentler interactions of second, or even third use former Bourbon barrels. American single malts may also use Sherry casks from Spain, Port casks from Portugal, Caribbean rum casks, even unique wine casks or new charred oak barrels.

This freedom points to a potential plethora of flavor profiles for the American single malt category. Often, consumers can expect a more subtle, layered complexity in American single malts with notes ranging from soft stone fruits, to rich toffees and dried fruit, to earthy chocolate and barrel spice, with endless possibilities of flavor and aroma combinations along the way. Water, yeast and barley may sound like a simple recipe, but the steps along the route guarantee that the taste will be anything but simple.

A BRIEF HISTORY OF AMERICAN SINGLE MALT

One of the early pioneers of American single malt was Steve McCarthy, who started Clear Creek Distillery in Portland Oregon in the 1980s. In the next decade, McCarthy’s Oregon Single Malt Whiskey came onto the scene, breaking ground for the American single malt category. That was followed up by St. George Spirits producing an American single malt in 2000, Stranahan’s in 2004, and then Balcones in 2008.

So why has it taken so long for 100% malted barley whisky to be a thing in the United States when Scotland has been doing it for centuries?

James Anderson was a significant player in the American whisky field, whose story mirrored that of many American distillers. A successful barley farmer in Scotland, Anderson spent years honing his craft. In addition to supplying barley to some of the largest Scottish whisky distilleries, he also owned his own whisky distillery and mill. In the early 1790s Anderson moved to the newly formed United States with his family. He was recruited to become George Washington’s farm manager at Virginia’s Mount Vernon in 1796.

James Anderson wasted little time before approaching Washington with a plan to open a whisky distillery. Anderson’s background with barley and his knowledge of how well it suited whisky production was met with an obstacle: the rocky soil at Mt. Vernon. While hardy rye was plentiful, barley struggled to grow in the challenging soil. In true American spirit, Anderson experimented with rye and corn, while still incorporating as much barley as he could obtain. Researchers have discovered that the whisky’s mash bill from 1798-1799 was 60% rye, 35% corn and 5% barley.

Visit any Bourbon distillery today and ask what their rye or Bourbon mash bill is and they will likely mention at least 5% barley as well. Malted barley is the one grain that contains the crucial enzyme amylase. Amylase is special because it can split starches – not just in barley, but in other grains too. When we talk about grain being one of the three core ingredients in a whisky, it’s really the grain’s starch that is needed. Thanks to barley’s enzyme amylase, we’re able to access the sugars needed for fermentation. And as we all know, without fermentation there would be no alcohol.

Expensive as barley may be and tricky as it is to grow, barley has been hailed the world over as a premium grain: the best at converting starches to fermentation ready sugars. It is also heralded as a romantic trailblazer from the first great whiskies distilled in Scotland and Ireland, and a delicious component that adds malty sweetness and nutty, biscuity notes to a whisky.

Thanks to modern technology and increased education from the traditions of the Old World, American distillers are beginning to turn their attention once more to barley.

STILL TYPES

Single malt whiskies are traditionally distilled in copper pot stills. Copper, an excellent conductor of heat, is also helpful in removing undesirable sulphur compounds from a spirit. The shape, height and size of a still can play a large part in determining the character and flavors of the final spirit.

Pot stills work through a batch process where a fermented beer or “wash” is heated up in the still. Because alcohol boils at a lower temperature than water, it separates in a gradual reflux, turning into a vapor, before condensing back into a liquid to be gathered and then sent on to a second distillation. Many distilleries have multiple pot stills and refer to the first still as the wash still, and the subsequent still(s) as the spirit still.

Other smaller distilleries clean out their single pot still before reusing for a second distillation. Some distilleries, particularly in Ireland, but also some Scottish distilleries like Auchentoshan, triple distill their whiskies. Each distillation increases the ABV of a spirit, but distilling more than three times is generally thought to strip out more character and flavor in a spirit than would be desirable.

The column or continuous still is an efficient way to achieve a high proof spirit in a relatively hands off manner. This is most ideal for vodkas and gins, as spirits distilled in this manner typically have fewer congeners than their pot distilled counterparts, and thus less flavor character.

Multiple column stills take things even further when it comes to achieving a pure-strength spirit, and hybrid stills (also referred to as pot and column stills) fall in the middle between the efficiency of a continuous still and the character retention of the pot still method. Thus, you’ll find that many American single malts are distilled in copper pot stills.

CASK TYPES

When it comes to aging American whisky, Quercus alba (white oak) has long been king. This native North American tree was in abundant supply when early distillers and merchants were looking for containers to store and ship their wares. It would have been more expensive and more trouble than it was worth to ship the barrels used to send whisky down the Mississippi River back up it, so new oak barrels continued to be manufactured and used for whisky aging.

By the 1960s the use of new barrels was fading, when the United States Government threw a gift to American coopers. In updating the standards of identity for Bourbon, they incorporated a requirement for the whisky to be stored in charred, new oak containers. Note that the American Oak is not specified, although it is usually seen as a given.

For the rest of the whisky world, many distilleries were delighted to take the used barrels from Bourbon production to use for aging their whiskies. Single malts in particular do well with a more gentle interaction with the wood, avoiding the harsher tannins found in new charred oak, although some American single malt producers desire a more wood forward expression and have used new oak in their maturation. Hillrock Estate’s single malt is initially aged in new charred oak barrels before moving to other barrels for finishing.

CASK VS BARREL: WHAT’S THE DIFFERENCE?

A cask is simply a large barrel shaped container, comprised of staves, headings, and hoops intended for holding liquid (usually alcoholic).

A barrel is at its broadest definition a shape – a container of greater length than breadth, that when used in the storing of alcohol is typically made of wooden staves joined with metal hoops and flat ends or heads. Other cylindrical containers made of materials such as plastic or metal may be called barrels or drums.

Some may use the two terms interchangeably, while others will argue that a barrel is a specific unit of measurement, which is correct in scenarios like a Bourbon barrel which are 50–53 gallon (180–200 liter) casks.

Non-Chill Filtration

Don’t Panic! What’s that cloud in the whiskey?

Our Whisky is per the label ‘non-chill filtered’; Don’t Panic ! What you are seeing is the flavor and it’s normal, the larger producers use chill filtering to remove this to make it look pretty. Which also has the impact of taking away some of the flavor and mouth feel.

Chill filtration is a common practice with most large batch producers, while we filter out the wood particles we want to provide the exceptional maximum flavor . So we do not employ chill filtration at THE MACKLOWE , which maximizes the flavor! That’s what the cloud haze is – gold nuggets of flavor proteins

If you just shake the bottle twice it will dissipate and disperse back into the liquid. You might notice that colder climates cause the clouds, just warm your bottle up to room temperature. We recommend a few drops of water or whiskey stones over ice to prevent this from happening when you drink it. The most important part is to enjoy your drink and the full flavor of the whiskey!

Cheers! Julie

Batch numbers

When reaching for a bottle of whisky in a liquor store, you may notice a batch number on the bottle. This does not refer to the process of batch distillation, but rather serves as a way to denote a single bottling run of a whisky. This is more commonly seen with American whiskies, particularly Bourbons, but batch designations can be found in many categories including ryes and single malts. Some see the batch numbers as the whisky industry’s answer to the concept of a vintage, due to the connection to specific years of production and aging in the whisky selected for a specific bottling.

The number of barrels used or the number of bottles produced in a single batch may vary widely. Even the term “small batch” is vague enough to carry no legal weight. It could mean two barrels or two hundred barrels were used. Varying batches of a whisky product typically demonstrate a level of consistency, while showing some changes in aroma, flavor or mouthfeel to varying degrees based on ingredients used, production processes and climate impacts.

AGE STATEMENTS

Although age statements on a bottle of whisky are generally optional, the meaning of an age statement carries no room for debate: it always reflects the age of the youngest aged whisky component in the bottle. So, if a specific whisky is comprised of barrels that have aged 6, 8 and 12 years, the age statement must be 6 years. There are times when an age statement is mandated by government regulations. For example, the TTB (Alcohol and Tobacco Tax and Trade Bureau) requires American distilleries to disclose when a whisky is aged under four years.

Age statements were initially instituted to convey quality (and eventually exclusivity as a marketing strategy), but today’s whisky distillers and consumers are increasingly aware of the fact that aging from one country’s climate to another’s can be widely different. A whisky aged 50 years in the relatively consistent climate of Scotland might only lose 1% of its volume in a year, where a barrel of Bourbon aging in Kentucky, or a single malt aging in Virginia could very well be bone dry after 35 years. The color, aromas and flavors achieved in one year of aging whisky in Taiwan or Virginia could easily meet or exceed those achieved in three times that length in Scotland or Ireland. India has such an arid aging climate that a barrel of whisky could evaporate within just a few short years.

Cask finishing an already aged whisky does not count toward an age statement, even though evaporation and loss may still occur in these barrels. Whisky does not age in bottle, so a 12-year-old Scotch bottled in 1987 will still be a 12-year-old whisky if it’s opened today.

Peated Whisky

Peat is a natural substance made over thousands of years from decaying vegetation. The northern part of Scotland is abundant with peat, as it was part of the vast Caledonian Forest for many thousands of years. Islands such as Islay have an abundance of peat thanks to seaweed, moss and other decayed vegetation found along the islands’ coasts.

Some distilleries use peat as the heat source for drying the barley, which gives the whisky a deep, smoky, and at times medicinal flavor. Peat is measured by ppm (parts per million) and the intensity of peat notes in whisky is generally derived by the treatment of the peat and the amount of time the barley is exposed to the peat smoke as it dries.

A peated whisky will lead to notes of sea spray, iodine, seaweed, medicinal, band-aid, or even a green and earthy bitterness. Barrel smoke will lead to a cleaner smoky note reminiscent of an autumn campfire, charcoal, or even ash.

For American single malts aged in charred barrels, the smoky notes from that barrel char should be a nice addition to the whisky’s complexity, but should in no way overpower the spirit. Some producers like Westland Distillery have released a peated American single malt using a majority of non-peated malt in their barley bill to ensure the peat doesn’t dominate. Other distilleries, like Santa Fe Spirits, embrace the smoke and use mesquite smoke to allow barbecue aromas to reign supreme in their Colkegan Single Malt. Corsair Distillery’s Triple Smoke American Single Malt is another standout in the smoke category, thanks to their use of peat, smoked beechwood and smoked cherry wood in the malting process.
