Can you make a 10-year malt whisky in weeks? The chemistry says yes
Over the past few years the whisky-drinking world has been introduced to several new products that claim to produce high-quality liquor in just a fraction of the time usually required to age single malt spirits. Instead of maturing the whisky for a decade or more in oak barrels, some distillers say they can replicate the quality and taste in a matter of weeks.
As global whisky consumption continues to rise, could these new ageing techniques be the answer to protecting supply? Or are the claims too good to be true? And even if the taste measures up, does that still necessarily make it the same as a fine aged malt?
Recent innovators in this field include Lost Spirits, whose prizewinning rums and single malts use a patented combination of light and heat to speed up the ageing process. Cleveland Whiskey creates whiskies and bourbons in high-pressure stainless steel tanks that mix the spirit with new wood combinations, creating unique flavours in days.
Highspire Whiskey uses wine barrels and adds oak wood chips to get a product aged in just four months. Tuthilltown Spirits, a distillery based in New York, blasts music through stereo speakers to get their barrels vibrating!
Australia's homegrown example is Deviant Distillery based in Tasmania, which claims to have created a single malt spirit that has the "chemical composition and flavour identical to a 10-year-old whisky". Before we test the validity of such a claim, we should review how brown liquors are made.
Interesting developments - introducing tiny bits of oxygen works. Using oak chips or staves from used wine barrels is used a lot by beer brewers and cider makers. A lot cheaper than trying to use the real oak barrels - these can run several hundred apiece and require very careful maintenance once first used. If they are allowed to dry out, the wood can become infected with wild yeasts which would change the flavor profiles completely.
