This is a single malt Scotch whisky bottled by Infrequent Flyers from a single cask at cask strength. Croftengea is a heavily peated style associated with Loch Lomond distillery, so this whisky is likely to show a bold smoky character alongside the individuality of one hogshead cask.
At 19 years old and 54.5% ABV, it is likely to offer a more mature take on peated whisky, with concentrated flavour and no dilution before bottling. For a novice drinker, expect a robust style where smoke and oak are central, and a little water may help open it up.
