Auchentoshan 24 Years Old 1992 Cask #530 (Signatory)

Bottled by Signatory Vintage in 2016 as a 24 year old single cask release, drawn from cask 530 of 1992 vintage Auchentoshan with 226 bottles distributed to the Netherlands market at cask strength of 53.2%. Signatory Vintage was founded in 1988 by Andrew Symington and is one of Scotland's most established independent bottlers, also operating Edradour Distillery in Pitlochry.

Distilled in 1992 from 100% unpeated malted barley with Loch Cochno water from the Kilpatrick Hills, the wash was fermented around 62 hours in Douglas fir and stainless steel washbacks before triple distillation. Auchentoshan runs every drop through three copper pot stills, with the intermediate and spirit stages lifting cut to 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 filled into a single ex Bourbon American oak cask.

Twenty four 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 53.2% across more than two decades indicates a tight cask and slow evaporative loss, and tertiary stage ester transformation integrates fruit and oak into a polished single cask profile.
