Auchentoshan 15 Years Old 1998 Cask #102388 (Silver Seal)

Bottled by Silver Seal in 2014 as a 15 year old single cask release, drawn from cask 102388 of 1998 vintage Auchentoshan with 210 bottles distributed to the Polish market at high cask strength of 60.4%. Silver Seal is an Italian independent bottler founded in Verona by Massimo Righi, known for selecting single casks at natural strength under hand designed label artwork.

Distilled in 1998 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.

Fifteen years in temperate Lowland maturation drove measured 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 60.4% across fifteen years indicates a tight cask with minimal evaporative loss, and continued ester transformation layers concentrated fruit over the spirit's signature citrus and almond core.
