Wood-Finished Whiskies Come of Age

Distilling whisky requires a special balance. On one hand, distillers are pressed to produce a consistency of flavour year after year to maintain brand loyalty. On the other, there is a desire to delve a bit deeper, to nudge the tastes of a classic whisky into new territories without compromising brand integrity. This is where the world of wood-finished whiskies is finding a growing audience of admirers.

Into the Woods

Wood finishing (or secondary maturation) is a relatively recent phenomenon in the scope of whisky history. It refers to taking a fully matured whisky – commonly aged in either an ex-bourbon or sherry cask – and then re-casking it for anywhere from a few months to a few years in another type of barrel, such as a spirit, wine, port or sherry cask. The initial maturation establishes the familiar taste and body while the secondary maturation enhances the flavour. The result is a whisky with its own unique shades and subtleties.  

 

The Roots of Wood Finishing

The practice only started in the 1980s when some independent bottlers started to experiment with different wood finishes. Credit the likes of Balvenie and Glenmorangie for  taking it more mainstream – they were among the early adopters, experimenting by re-casking single malts into sherry butts. A steady march of other distilleries followed in step.

 

A Depth of Flavour  

Two main factors contribute to the taste of a wood-finished release. There is the wood itself, which imparts a distinct flavour, and then there is whatever previously occupied the cask, as casks absorb a significant amount of the previously held liquid. This is commonly referred to as the ‘in-drink,’ which is drawn into the whisky to help add greater texture and taste. Discussions range over which exacts the greater impact on the final product, but whatever weight each factor carries, the combination creates something wholly unique.

 

Creating Balance

Beyond the inherent trial-and-error nature of the practice, not all casks are appropriate for secondary maturation. The  pronounced flavours of some casks may simply overwhelm more delicate whiskies, while lighter-flavoured wine casks would hardly register any influence if matched with a more heavily peated whisky. The key is to find the complementary flavours that deepen the taste profile and highlight the best of the original whisky and the ‘finishing’ factors.
