The Glenlossie Distillery is a Diageo-owned distillery that, while perhaps not as widely known, is highly regarded for its light and fruity spirit, a key component in Diageo's major blends.

Established in 1876 by John Duff, who previously managed Glendronach, Glenlossie is situated near Elgin in Speyside, surrounded by several other distilleries including Glen Moray, Glen Elgin, Longmorn, BenRiach, Linkwood, and Miltonduff. An interesting point is that in the early 1970s, the Mannochmore distillery was constructed on the same grounds as Glenlossie. This expansion followed the addition of two stills to Glenlossie in 1962, bringing its total to six. Currently, Glenlossie and Mannochmore share both warehouse facilities and staff, with the team reportedly splitting their time between the two distilleries' production.

A notable feature contributing to Glenlossie's delicate character is the purifier pipe. This element, part of the original design by John Duff, redirects heavier alcohol back into the still for further distillation and remains in use today.

Although there are no official distillery bottlings from Glenlossie, it is occasionally featured as a single malt in Diageo’s Flora and Fauna series. This makes independent bottlers' releases of Glenlossie spirit particularly noteworthy, as they are quite rare even in the independent market.
