Well now, this is something. 31 year old Bunnahabhain is quite a find – even Bunnas in their 20s are quite rare, so one in its third decade is ever rarer. This whisky usually hits excellence between 12-18 years, and so either gets bottled or goes for blending in that period. Older casks present a whisky that is almost chewy with gingery molasses flavours, and are highly prized.
This whisky is old enough that a closer eye should be kept on it. The abv has dropped below 50% and there are about 40 litres of pure alcohol still in the cask, so a few more years of maturation may see the whisky come close to the minimum of 40% abv. This is one to be bottled before too long.
Auction estimate: £40,000 – £45,000
