Glenfarclas 105 is a superb cask strength whisky, with a history that can be traced to 1968. When the original incarnation was released that year, Glenfarclas became the first distillery to release a barrel proof single malt whisky. The bottling was eventually re-named to 105, referring to its alcohol content in British Proof, which equates now to 60% ABV. The 105 doesn't carry an age statement presently, making it rare among Glenfarclas bottlings. Although, there are suggestions that it is matured for 8-10 years in a combination of both ex-sherry and ex-bourbon barrels.
