Glenlossie 20 Years Single Malt Whisky

Glenlossie Distillery, established in 1876 by the legendary Victorian whisky pioneer John Duff—former manager of Glendronach and founder of Longmorn—stands as a quintessential Speyside producer. Nestled in a tranquil pine forest north of the River Spey, its distinctive white harled buildings exemplify traditional Morayshire architecture. The distillery began with a single water-powered still, converting to steam heating only in 1919. A major expansion in 1962 tripled capacity to three stills, catapulting production forward. Now under Diageo ownership, Glenlossie has earned renown for exceptionally extended fermentation periods, yielding a spirit of remarkable purity and finesse. The late whisky authority Michael Jackson famously characterized its profile as "pure floral, grassy and malt notes," epitomizing the delicate Speyside style. The vast majority of output—approximately 98%—serves as premium blending stock for iconic brands including Cutty Sark, Famous Grouse, and Haig Gold Label, making official single malt bottlings exceptionally scarce (representing merely 0.5% of total production). The distillery underwent an extensive 18-month closure from January 2018 to June 2019 for comprehensive modernization, including new stainless steel washbacks, a state-of-the-art 8-ton full-lauter mash tun, and complete infrastructure replacement. While theoretical capacity reaches 3.7 million liters annually, current operations produce 2 million liters through a 5-day week schedule, utilizing both long (104-hour) and short (65-hour) fermentation cycles to achieve complex flavor development. The sole official single malt expression remains the Glenlossie 10 Year Old in Diageo's Flora & Fauna series.
