Treasurer's Selection Deanston 1995, 15 Years Old (70cl, 56.4% ABV)

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.

Pepper, cinnamon, ginger, herbs

Aged Scotch whisky is often much softer and easier on the palate than its alcohol strength would imply. So much so, in fact, that sometimes you need something to liven things up a bit. Luckily, a good number of single malts possess lively spicy flavours, some of them in great enough quantities to challenge tequila (naming no names). Others are a little more restrained, but still with the warming tingle of Christmas pudding and mulled wine.

A lengthy maturation, particularly in a large cask (e.g. ex-sherry), generally means more oxygen is allowed into the cask to react with the spirit and develop more complex flavours. These may include spicy flavours - lignin compounds break down over time, releasing more intense spicy notes into the spirit, while the high acidity and relatively low alcohol content of sherry often serve to bring out spicier notes from the cask wood. Clove and cinnamon flavours often derive from eugenols produced via toasting - that is, firing the wood of the casks over a medium heat for anything between 15 to 45 minutes (to be contrasted with charring, where the wood is fired for a very short time over a much hotter flame). Some of the most intense spicy flavours come not from the cask at all, but from the still: a lighter spirit (such as that produced in a tall still) will often have more kick than something more rounded.

Spicy characteristics are generally used to complement other strong flavours, such as dried fruit (e.g. Aberlour) or peat (Ardbeg), but the style is probably best showcased by the expansive and varied Highland region. Highland malts generally eschew excessive subtlety for bold and full flavours, and so often showcase strongly spicy styles. The best examples by far are in the Northern Highlands: Glenmorangie has a light spice that is perhaps better described as herbal; but a small distance to the north, Clynelish and Old Pulteney provide a salty, firey yet still sweet style that prickles all over the palate. Their eastern counterparts, such as Glen Garioch or Glendronach, retain a gingery warmth that it is not so much restorative as elixir.

The strength and spark of such potions pairs very well with similarly lively cigars: Partagas is an obvious match, as is Ramon Allones; but the peppery notes of a Cohiba or Bolivar will also go very well.

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.
