Likewise with very personal allusions like’ the inside of my grandfather’s car’. But the broader your experience of and exposure to different aromatic groups the better: flowers and herbs, cooking and cleaning, babies and hill-walking... Generally speaking, women are better at coming up with allusive descriptors than men, and some of the best noses in the whisky trade are women. Many of the words we use to describe sensations are abstract – general concepts, rather than strictly objective descriptors. These are as legitimate as similes and metaphors, but they describe an overall impression – the whisky’s construction (to borrow a wine term), general style, character and quality – rather than specific aromas. As such they are useful. But they are not precise, and since they cannot be defined by reference to a standard, they are not strictly scientific.Think of terms like ‘smooth’, ‘clean’, ‘fresh’, ‘coarse’, ‘heavy’, ‘light’, ‘rich’, ‘mellow’ or ‘young’. Some are relative terms (smooth compared to other malts, or perhaps other Speyside malts? Heavy for a Lowland malt?). Others have double
meanings (soft can mean a suppression of alcohol and pungency, or it can mean gentle mouthfeel; young can mean immature or lithe and well-shaped). Many more are imprecise (rich can imply an intensity of character, or can mean rich as a fruit cake; fresh can mean acidic or vibrant). Such loose descriptors should be used with caution.The first systematic attempt to define the language of whisky tasting was undertaken in the late 1970s by a group of sensory
scientists in Edinburgh, Pentlands Scotch Whisky Research (now The Scotch Whisky Research Institute). They displayed their findings in the form of a wheel. This is now the accepted way of tabulating aromas and flavours, but at the time it was novel.The Pentlands Wheel was for the use of the whisky industry, not the consumer, and could be applied to new-make spirit as well as mature whisky. With Dr Jim Swan (one of the wheel’s original authors) and Dr Jennifer Newton (his partner at Tatlock & Thompson, Chemical Analysts to the Whisky Industry), and drawing upon a vast lexicon of descriptors gathered from tasting panels over many years, I am currently working on Pentlands’ findings to produce a wheel which will be more useful to the consumer; the wheel you see here is work in progress.The wheel has eight segments and three tiers. Users can begin from the outside rim, with the kind of vague aroma description which often arises spontaneously during a tasting, and work inwards to the core aromas on the first tier, or vice versa.The order of the segments broadly reflects the development of aromatics during production (sections 1-6) and
maturation (sections 6-8).
Aromas arising during production are:
1) Cereal: these aromas come from the alted barley, and are usually modified by the later stages of production (fermentation and distillation).2) Fruity (the scientific term is ‘estery’): the sweet, fragrant, fruity, solvent- like scents which characterize Speyside malts in particular, arise during fermentation and distillation. 3) Floral (or ‘aldehydic’): leafy, grassy or hay-like scents, sometimes like Parma violets or gorse bushes, and often found in Lowland malts.
4) Peaty (also called phenolic) – these scents are abundant in Islay malts and range from wood-smoke to tar, iodine to carbolic. Almost all phenols are imparted to the malt during kilning.5) Feinty: this last group is the most difficult to describe, yet feints give whisky its essential character. They start coming in halfway through the spirit run, beginning as pleasant biscuity, toasted scents, then build through tobacco-like and honeyed to sweaty. The wise still-man stops collecting spirit at the honeyed stage, for the deterioration can be dramatic thereafter. Feints are mellowed and transformed by maturation in good casks.6) Sulphury (from organosulphur compounds): these arise during bothdistillation and maturation. Copper plays a crucial role in removing such aromas, which are generally unpleasant. Maturation introduces the last two key aromatic groups: 7) Woody: the vanilla-related aromas in this group derive from American white oak. Some woody aromas are directly related to age: malts can become woody when they have been in cask for too long. Oak increases complexity, enhances fragrance and delicacy, creates astringency, lends colour and develops roundness. 8) Winey (also called extractives): if the cask has previously been filled with wine (mainly sherry, but sometimes port or others), the wood absorbs wine residues, which are extracted by the spirit and become part of its flavour.The descriptive language of whisky tasting sets out to be as objective as possible, and to use precisely defined terminology. But the descriptors are a guide only. Use your own words and, if you like, group them under the various primary tier headings. Hold your own whisky tastings; see how colourful and original you can be in describing the whiskies. You will know your descriptions are accurate when the other members of your panel nod enthusiastically and exclaim, ‘Yes! Yes! I Know just what you mean – tea-time on a fishing boat stormbound in Mallaig harbour’.
