On Blending

Some thoughts from Emily Vikre.

A few months ago I sat in my office with an array of whiskey samples in front of me.  They were all the same whiskey from our distillery - Sugarbush Whiskey, a bourbon mash aged in a mix of barrels previously used for port and for bourbon - and they had all aged the same amount of time in our barrel room.  But, each sample – each taken from a different barrel – tasted markedly different.  I tasted, scribbled notes, and gradually decided which four barrels we would mix together to comprise our next release of this whiskey. 

Personally, I think of this as blending whiskey - and the person in charge of pulling barrels to comprise any given whiskey release is generally referred to as the blender - but in the industry, mixing whiskey barrels from one distillery is generally called vatting.  Unless a whiskey is a single barrel release, it is virtually always vatted.  On the other hand, blended is often a dirty word when associated with whiskey, denoting poor quality.  So, what gives?

As with many things, “blended” whisky was historically really good.  Then it earned a bad reputation because problems with quality arose, but has since begun to transcend its reputation in practice, if not in our psyches.  (As a side note, whether or not you put an e in whiskey depends on what country you’re in, and often varies based on which country’s whiskey you’re talking about)  In the mid to late 1800s in Scotland, blended whisky was developed to make a softer, more palatable alternative to the insanely heavily-peated malt whiskies that were being made at the many tiny distilleries dotting the country.  The blended whiskies combined malt whisky (distilled from malted barley) with gentler, smoother grain whiskies (made from any grain that isn’t malted barley).  Thus was born the likes of Johnny Walker, a blended whisky that still lives and reigns today.  But, in more recent years large quantities of high quality, long-aged single malt whisky started to become available lifting single malt to the throne as king of whisky.  At the same time, many blended whiskies had gradually begun to cut corners and costs by using lower quality grain whisky and sometimes adding neutral spirits which adds bulk without contributing any flavor, thus compromising the quality of the overall spirit.

 
 

Therein lies the rub.  Blending is not inherently bad, in fact it has the potential to be very, very good.  But any blend is really only going to be as good as the quality of the things you put into it.   Think of blending whisky like blending paint pigments (I’m into paint analogies lately).  Imagine you’re making a painting of a stormy sea that’s boiling blue-green-grey.  On your painter’s palette you have a nice brilliant green, a nice royal blue, and so on.  None of these colors will evoke the sea in the way you want to, so you mix drops of them together to create a new color.  The colors you choose to mix, as well as the proportion of each, will alter what the final color winds up being.  And, if one or two of the paints you use are bad quality, maybe really clumpy or thin so they don’t give good coverage, this will make the final paint worse.  However, if all the pigments you start with are nice, you can mix up precisely the blue-green-grey of the sea that you’re going for.

Some blended whiskies have returned to the approach of blending high quality whiskies to create something different and more balanced than any of the individual whiskies that go into the blend.  Compass Box, is a notable example of thoughtful blending that I find incredibly inspiring.  And I am delving into it myself because it is a fascinating art (plus, there aren't nearly enough women aspiring toward becoming master blenders!).   This is also the approach that has long been used in wine.  It is true that these days the single varietal wines have become popular in a way they never have been before.  We reach for the Cabernet Sauvignon, the Pinot Noir, or the Chardonnay, instead of the “red blend” or “white blend” because an unspecified blend may sound non-descript.  But, many, even most, of the world’s truly great wines are blends.  Blending the wine from different grapes allows a winemaker to work toward their perfect marriage and balance of fruit, acidity, tannins, and alcohol to create a wine that can be more fetchingly complex than a wine made from a single grape varietal.  A red Bordeaux, for example is usually a blend of Cabernet Sauvignon, Merlot, Cabernet Franc (and sometimes other grapes as well).  The Merlot’s plummy velvet softens the sometimes rigid structure and savory notes of Cabernet Franc.  The Cabernet Sauvignon boosts the other two with its powerful body and complexity.  And different estates in different years may make adjustments to their blends to create their own style and realize their own vision for what their wine should be.

Speaking of creating your style, many commercial winemakers also blend their wine to try to achieve consistency from year to year.  When a brand has a specific taste that it knows its customers are looking for, the winemakers blend together wine from their different storage vessels and even from different years to try to create a consistent product.  And this brings us back to vatting with whiskey because for large whiskey distilleries with a signature flavor, the only way to achieve this flavor is to mix together multiple barrels of whiskey because the fact of the matter is, every barrel of whiskey ages slightly differently from the next. Even in single malt Scotch, the word single in there means that it is from a single distillery, but not from a single barrel or even a single distillation run.  Your single malt will be a blend of multiple barrels with the goal of achieving the distiller’s vision of balance and complexity.  And that brings us back to me, sitting with my samples.  I chose barrel numbers 29, 31, 32, and 33.  It’s a lovely whiskey.
