Auchroisk 7 Years Old 2017 Cask #UC039 (Uncharted Whisky Co.)

Bottled by Uncharted Whisky Co. in 2024 as a 7 year old single cask release, drawn from cask UC039 of 2017 vintage Auchroisk with 720 bottles distributed globally at high cask strength of 59.1%. Uncharted Whisky Co. is an independent bottler focused on hand selected single cask releases at natural strength, with selections drawn from across Scottish distilleries.

Distilled in 2017 at the Mulben distillery built by Justerini & Brooks in 1974, the wash was made from 100% unpeated malted barley with soft Dorie's Well water and fermented for around 53 hours in stainless steel washbacks. Auchroisk runs the spirit through four wash and four spirit stills with constricted lyne arms, encouraging high reflux that returns heavier compounds back to the pot. Shell and tube condensers give further copper contact, stripping sulphur compounds, with the spirit collected at around 70% ABV and filled into a single Oloroso sherry cask.

Seven years in European oak Oloroso conditions drove deep sherry character into the lighter Speyside base. Ellagitannins and gallic acid from the European oak build dried walnut and grip, while oxidative aldehydes including acetaldehyde and syringaldehyde develop nutty, leathery rancio. Fermentation derived sotolon adds dried fig and curry leaf, with slow concentration of glycerol lending body, integrated with the spirit's underlying light ester signature at 59.1%.
