Auchroisk 1991 27 Years Single Malt Whisky

Auchroisk is the fourth distillery established by Justerini & Brooks (now part of Diageo), joining Knockando, Strathmill, and Glen Spey. Production began in 1974 after water from the discovered Dories Well source successfully replicated Glen Spey's style in tests. Located in Speyside off the A95 between Keith and Craigellachie, the modern distillery lacks traditional pagoda roofs. It operates 24/7 with a 12-ton stainless steel mash tun, eight 53-hour fermentation washbacks, and four still pairs, producing approximately 5.8 million liters annually of new make spirit with nutty, malty character (previously grassy). The 1986 Singleton release was Auchroisk's first single malt, now a Diageo brand covering Dufftown, Glendullan, and Glen Ord. Replaced by Flora & Fauna 10 Year Old in 2001, limited editions include 20 and 30 Year Old Special Releases, plus a 25 Year Old (1990 vintage, 51.2% ABV) in October 2016.
