Whisky Tasting Quiz: Flavour Profiles, Peat, Casks & Notes
Phenols or esters? Ten questions on peat smoke, sherry-cask dried fruit, bourbon-cask vanilla and regional flavour styles, with answers and explanations.
Do you know what gives an Islay single malt its medicinal TCP aroma, or why Spanish oak yields aromas of Christmas cake and dark chocolate?
Tasting whisky is both a sensory art and an organic chemistry puzzle. Between wood species, cask history, peat provenance, and molecular dilution, the compounds inside your glass tell the exact story of how and where the whisky was made.
Test your palate and nosing expertise with these 10 questions on flavour chemistry, peat smoke markers, cask finishes, and sensory tasting technique.

What chemical compounds produce the medicinal, iodine, bandage, and TCP aromas famously found in coastal Islay single malts like Laphroaig?
Islay peat is formed primarily from maritime sphagnum bog moss and decaying marine matter exposed to Atlantic salt spray. Kilning over this peat releases cresols, guaiacols, and xylenols, imparting the legendary medicinal, iodine, and TCP character celebrated by peated whisky fans.
What primary oak-derived chemical compounds contribute the sweet aromas of creamy vanilla and toasted coconut in American White Oak ex-bourbon casks?
During cooperage toasting and charring, wood lignin breaks down into aromatic aldehydes (vanillin), while American oak staves release cis- and trans-whisky lactones, responsible for the signature coconut, sweet cream, and vanilla notes that define bourbon-cask maturation.
Whiskies matured in Spanish European oak casks previously seasoned with Oloroso or Pedro Ximenez sherry are famous for which classic flavour profile?
European oak (Quercus robur) has wide growth rings and rich tannin levels. When seasoned with dark, oxidative sherries like Oloroso or syrupy Pedro Ximenez, it infuses the whisky with luscious notes of Christmas cake, raisins, prunes, dark chocolate, and baking spice.
According to molecular dynamics research (Karlsson & Friedman, 2017), why does adding a few drops of water to a dram improve its aroma?
In high-strength whisky (50%+ ABV), aromatic compounds like smoky guaiacol and fruity esters remain bound among ethanol clusters throughout the liquid. Adding water pushes the mixture below ~45% ABV, driving hydrophobic flavour molecules to the liquid surface where they vaporize into the glass.
On the standard Scottish Whisky Flavour Map, which two perpendicular axes are used to plot and categorize single malt styles?
The classic Flavour Map plots single malts across two axes: Vertical (Light to Rich / Heavy body) and Horizontal (Delicate / Fresh to Peated / Smoky). This allows drinkers to navigate between styles like light delicate aperitifs and rich peated digestifs.
What is the flavour profile difference when a distillery uses "Virgin Oak" casks (brand new oak barrels) compared to traditional refill Scotch casks?
Unlike refill casks whose active staves have already been depleted by prior fills, virgin oak staves possess 100% of their raw wood extractives. They extract rapidly, imparting intense cinnamon spice, toasted bread, raw wood sugars, and firm dry tannins.
Why is a dark mahogany or amber colour NOT a guaranteed indicator that a whisky is exceptionally old, rich, or high in quality?
Colour is determined by wood type, fill history, and legal additives. A refill American oak barrel may yield a delicate pale-straw colour after 30 patient years, while a young 3-year-old whisky can appear deep mahogany through heavy E150a colouring or a wet first-fill sherry cask.
What flavour character does a "Port Pipe" or "Madeira Cask" finish typically contribute to a finished single malt?
Port pipes (seasoned with fortified red Portuguese wine) and Madeira drums impart rich, stewed red berry notes: dark cherries, black currants, plum jam, and nutty rancio complexity, often with a distinctive reddish-bronze or copper blush.
What happens to the flavour profile of a half-empty bottle of whisky left on a shelf for three to five years?
When a bottle has only a third or quarter of its liquid remaining, the extensive headspace of air permits slow oxidation. Delicate fruity esters and pungent smoky cresols gradually oxidize and flatten, making the dram taste softer and less vibrant over several years.
In whisky tasting terminology, what does the "Finish" of a dram refer to?
The "Finish" is the third sensory act of whisky tasting (after Nose and Palate). High-quality whiskies feature long, evolving finishes where wood spices, peat smoke, warming oils, and complex sweetness linger and develop for minutes after the dram is enjoyed.
