Auchroisk 15 Years Old 1978 (Authentic Collection)

Bottled by Cadenhead's in 1993 as a 15 year old release in the Authentic Collection, drawn from 1978 vintage Auchroisk and distributed to the German market at cask strength of 57.5%. The release represents one of the earliest indie bottlings of Auchroisk on record, drawing on stock laid down within four years of the distillery's 1974 founding. Cadenhead's was founded in Aberdeen in 1842 and is the oldest independent bottler in Scotland, now operated by J&A Mitchell of Springbank Distillery.

Distilled in 1978 at the Mulben distillery built by Justerini & Brooks four years earlier, 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. Shell and tube condensers give further copper contact, stripping sulphur compounds, with the spirit collected at around 70% ABV and filled into ex-Bourbon American oak.

Fifteen years in temperate Speyside warehousing 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 57.5% across fifteen years indicates a tight cask with slow evaporative loss, and continued ester transformation layers polished fruit over the spirit's signature light, ester forward profile.
