Glenfiddich 18 Year Old Single Malt Scotch Whisky (20cl 40%)

Sherry casks, cedar, mahogany, cigar box

Whisky, by definition, is a grain spirit aged in oak casks - and it is the influence of this wood that produces they greatest variation of flavour. Different species of oak result in different flavours, while the previous contents of the cask has a major impact on the style of the resulting Scotch. A whisky may spend anything from three years to thirty years in wood - in some extreme cases even longer than that. Yet there are only certain cases where the resulting spirit can be said to ‘taste of wood’.

The most obvious example is when the whisky has been aged for an exceptionally long time. Conventional whisky wisdom claims that any period of ageing beyond about 25 years is wasted or even detrimental, because the spirit begins to taste more like the wood it is stored in than anything else. As a result, subtleties of flavour built up over years of maturation will be lost as the wood takes over. A certain amount of woody flavours may be desirable, however, not least because it implies that a whisky has spent a considerable amount of time ageing and has likely reached the peak of its complexity. For this reason, single malts over 25 years of age are relatively scarce (not to mention expensive), but often in high demand.

The wood of the cask imparts tannins to the spirit inside: tannins are a compound that produce a dry or astringent flavour, as found in red wine, unripened fruit, black tea…and heavily oak-influenced whisky. This means the flavours in question may be found in whisky aged in wine-influenced casks, such as those which have previously held sherry, port or red wine, as opposed to bourbon; therefore it is not always necessary for a whisky to have been aged for a very long time in order for woody flavours to be apparent. Notes of mahogany, cigar box cedar-wood or varnish are relatively common among the more savoury styles of single malt, such as complex Speysides or some Islay whiskies.

Wood is also a common flavour in many cigars, which can be expected to pair well with a woody whisky: Romeo y Julieta and Montecristo are both excellent examples, while Fonseca and Diplomaticos are good choices among the lesser known brands.

Raisins, figs, fruitcake, red grape, candied fruit

While flavours of fresh fruits such as apple, citrus or berries may be the result of ex-bourbon cask maturation, dried fruit flavours in single malt are almost exclusively due to extensive sherry-cask influence. Sherry casks, especially those made from European Oak (very much the minority today) lend whisky bold and robust flavours: the high acidity and lower alcohol content of sherry (in comparison to bourbon) bring out more of the flavour from the wood, giving the whisky notes of rich dried fruit and spice. In addition, the fact that sherry casks are generally larger than bourbon barrels (250 - 300 litres for a Hogshead or 500 litres for a butt, in comparison to 200 litres for a barrel) means that there is a slower maturation process: the more time the alcohol has to break down the flavour compounds present in the wood, the more oxygen becomes available to react with the spirit via oxidation; this results in more complex flavours including tobacco, spice, and a rich but sweet fig-like flavour. Raisins and fruit cake are common tasting notes, but younger (and therefore sweeter) whiskies may also present red grape, candied papaya or dried banana chips.

Due to their association with sherry casks, dried fruit flavours are most common in Speyside whiskies which make extensive use of this cask type. Many distilleries in this region have made sherry cask maturation their trademark: most notably Macallan, but also Aberlour, Glenfarclas and cult favourites Glendronach and Longmorn. The scarcity of sherry casks and legendary status of the aforementioned malts has driven up the price tag of this style, but those in the know keep close tags on where to find the best “sherry bomb” deals.

The dry, rich characteristic of this set of flavours means it pairs well with the toasty flavours present in some styles of cigar: Macallan and Cohiba, considering the prestige of each brand, are a natural couple, but dried fruit sherry bombs are also likely to pair well with the likes of Ramon Allones or Trinidad, and the leathery tang of a Montecristo is another good companion.

Treacle, toffee, caramel, heather

The sweetness of honey is one of the most common flavours in Scotch whisky…particularly in younger examples of the popular Speyside style that forms the basis of many of the most popular blends, but also in the Highlands and, perhaps most characteristically, the Lowlands. The Island whiskies, too, often express a honey-like sweetness in their lighter forms. This is usually the result of the natural sugars present in malted barley, and so is generally more apparent in younger whiskies (up to 15-18 years of age) before too much of heftier flavours like wood, spice or dried fruit are imparted from the cask.

A richer, toffee-like sweetness often derives from European oak casks (generally ex-sherry), while American oak (ex-bourbon or newer sherry casks) produces a lighter, vanilla-tinged flavour that complements the natural sugars of the barley. The marshmallow-like sweetness of bourbon often translates into a lighter honey-like flavour in Scotch matured in ex-bourbon casks.

Good examples of single malts that carry strong flavours of honey are the classic Glenlivet and its many Speyside brethren; the lightness and softness of Lowlanders Glenkinchie and Auchentoshan; and the heathery sweetness of younger Highland Parks or some Highlanders like Dalwhinnie or Glen Garioch. In addition, virtually all of the biggest names in blended whisky are marked by this kind of flavour - the house styles of Johnnie Walker, J&B and Chivas Regal all depend on that sweet, youthful Speyside core. All of them are likely to go well with lighter cigars, particularly those with sweet flavours of their own, such as Hoyo de Monterrey.
