Recycling casks for scotch production is not only environmentally friendly, it makes great whisky as well! The Balvenie DoubleWood is a great example.
I'll admit it...I'm a tree hugger
Well, not literally. Trees are scratchy and can have ants and bugs on them (ewww!), or worse, spiders (shudder). No, I'm in favor of trees in a natural setting...forests, woods, glens, glades...you get the idea. I love being in a natural woodland setting, preferably with the sound of running water nearby. Growing up in the suburbs of Los Angeles, the trees there were planted for the housing subdivisions, so there weren't many real forests (although there are pine forests up in the mountains, but I didn't go there very often). When I moved to New England, one of the things that drew me in were all the woods nestled in with the cities and towns...the trees were preserved and the houses went up around them (what a novel idea!). And don't get me started on New England in the fall...WOW! New England's woodlands take my breath away.
I'm also frugal by nature (as an Outlander "Honorary Scot" I wear that badge proudly)...I don't like to see anything wasted, especially something like tree products because trees take so long to grow back. I'm always saving daily desk calendar pages to use as note paper. I have a vast collection of tote bags I use for shopping instead of getting paper (or worse, plastic) bags from the store (just ask my daughters how I used to make them run out to the the car to fetch the bags when I had forgotten them and we were checking out of the supermarket...ahh, good times). I hound my husband to print on the reverse of used printer paper. I like it when I can reduce the use of or reuse items, especially paper. So you understand how I can appreciate recycling casks for scotch aging.
So why am I going on about recycling wood?
Glad you asked! It's because the spirits industry is all about recycling, especially in whisky production. After the grain mash is distilled, the spirit is aged in wood casks. That's where a great deal of the flavor of the whisky is created...the type of wood the cask is made of and what was in the cask before the whisky was aged in it lends its distinctive characteristics to the spirit during the aging process. By hand selecting the casks for aging, a Master Distiller can produce a desired whisky taste. It's magic again, folks.
[Nerd Alert...lots of exposition about casks ahead. Proceed at your own risk, or just skip down to the tasting notes. We'll meet up with you later.]
So, what's in a cask?
(Ok, they've gone ahead, so tell us, tell us, more about casks!) Of course, how can I refuse such enthusiasm for knowledge? I'm going to speak generally now, as each individual expression of whisky will have its own distinct aging process (time, type of cask, etc.). Many whiskys start aging in Oak casks. Quoted from The Bourbon Review:
"Whiskey barrels made from Oak have three broad effects on the spirit:
- As an additive – It adds to the taste and aroma of the spirit by providing desirable elements from the cask. For example: vanillin, Oak lactone (coconut, bourbon character), toastiness, wood sugars and color.
- As an agent that removes undesirable elements from new make spirit. For example: sulphur compounds and immaturity.
- Oak barrels also interact with the spirit. It adds extractive wood elements from the cask and converts them to organoleptically desirable elements."
Whew, oak adds a lot of character! [Side note: "organoleptically" = characteristics that release to the senses (I had to look it up...the things you learn)]. One can write a dissertation on how all the aspects of Oak affect the spirit (it's growth rate, how the wood is seasoned, how the barrels are aged), and The Bourbon Review does a good job of presenting this info.
From there, the diversity of whisky really takes off -- the whisky can be aged a second time (or more) in casks recycled from the production of bourbon, port, rum, or sherry, just to name a few. Anyone ever heard of oloroso, fino, or amontillado sherry? I hadn't before I started research for this post. The secondary aging of the whisky in casks formerly used by other spirits adds another layer of complexity to the various expressions, e.g., sweetness, deeper colors, and even making the whisky more full-bodied.
Winning at trivia
Before we move on, here's a few more tidbits from The Bourbon Review that you can use to amaze your friends or win the pub's trivia contest:
- The wide-spread use of bourbon whiskey barrels is a fairly recent occurrence – a result of the difficulty in sourcing sherry casks during the Spanish civil war in the late 1930’s.
- Currently anywhere from 300,000 – 400,000 bourbon casks are acquired for use in the maturation of Scotch whisky – in contrast to only about 18,000 sherry casks.
- Contrary to popular belief, very few whiskies are aged exclusively in bourbon barrels – most ex-bourbon aged malts are vatted with a (varying) percentage of whiskey which was aged in ex-sherry barrels.
It's the little things, Gentle Reader, that bring the spice to life.
The Tasting - The Balvenie Doublewood
[For those that skipped ahead, nice to see you again. For those of you who stuck with me, I applaud your determination and quest for knowledge.]
The Balvenie distillery is located in Speyside next to its parent company Glenfiddich and home to also Kinnive whisky, in the most condensed areas for whisky making in all of Scotland. The typical character and style of Speyside whiskys include the flavors of apple, vanilla, oak, malt, nutmeg, and dried fruit. Now do you see why I've chosen recycled wood as the theme for this post? (yes, I have a method to my madness)...The Balvenie is famous for their flagship whisky, the DoubleWood 12 yr, and many of their offerings are distinctive by the choice of the recyced casks used for aging. Indeed, the names of their expressions give it away. To see the full descriptions of these and all of Balvenie's range of whiskys, visit their website.

It's interesting to me that because I tried all these whiskys at one time, the effect of the different woods was quite apparent. Each expression was so different, which, of course is the point of the whole idea. But being able to compare and contrast them all together really brought this effect home to me, and now I have one more tool to add to my tasting toolkit. Recycling casks for scotch aging may be environmentally friendly, and it produces great whisky as well!
Slainté! L'chaim! Cheers!
