Auchentoshan 22 Years Old 1992 Cask #5433 (Whiskybroker.co.uk)

Bottled by Whiskybroker.co.uk in 2014 as a 22 year old single cask release, drawn from cask 5433 of 1992 vintage Auchentoshan with 195 bottles distributed to the Belgian market at cask strength of 50.7%. Whiskybroker.co.uk is an independent bottler founded by Martin Armstrong, with a focus on releasing single casks at natural strength from across Scottish distilleries.

Distilled in 1992 from 100% unpeated malted barley with Loch Cochno water from the Kilpatrick Hills, the wash was fermented around 62 hours across Douglas fir and stainless steel washbacks before triple distillation. Auchentoshan runs every drop through three copper pot stills, with the intermediate and spirit stages collecting at around 81% ABV. The extra copper contact strips sulphur compounds and fusel oils while concentrating ethyl hexanoate, isoamyl acetate, and other light esters, giving a clean spirit base filled into a single ex Bourbon American oak cask.

Twenty two years in temperate Lowland maturation drove patient oak extraction. Vanillin from lignin breakdown gave vanilla, cis and trans oak lactones added coconut and sweet wood, and char layer interaction produced furfural with Maillard derived caramelised sugars. Holding 50.7% across more than two decades indicates a tight cask with slow evaporative loss, and tertiary stage ester transformation layers polished fruit over the spirit's signature citrus and almond core.
