Where is Mortlach Distillery?


Mortlach sits in Dufftown, Moray, in Scotland's Speyside region. It was the town's first licensed whisky distillery, opening in 1823 on the site of an older illicit operation.


Mortlach history: from the Cowie family to Diageo


1823: Dufftown's first legal distillery


James Findlater founded Mortlach following the 1823 Excise Act. Unlike many distilleries that arrived later, Mortlach established Dufftown's early reputation as a place of whisky production. William Grant, the future founder of Glenfiddich, worked at Mortlach before building his own distillery.


1853–1897: George and Alexander Cowie


Engineer George Cowie became associated with Mortlach in 1853 and later took sole ownership. His son Alexander Cowie returned from overseas and expanded the distillery in 1897 with engineer Charles Doig. The expansion brought the still count to six and introduced the complicated process now described as 2.81 distillation.


1923 onwards: Johnnie Walker and Diageo


John Walker & Sons acquired Mortlach in 1923. Much of its robust single malt went into blended whisky, where its depth of flavour proved particularly useful. Subsequent corporate changes ultimately brought the distillery into Diageo, which remains the owner today.


How Mortlach whisky is made: the 2.81 distillation process


Most Scotch single malts are distilled twice; Mortlach takes a more complex route. Three wash stills and three spirit stills operate through different paths, including a small spirit still known as the Wee Witchie. The resulting effective distillation figure is described as 2.81. It is a distinctive combination of spirit fractions, not 2.81 full passes through every still.


Mortlach also uses traditional worm tubs, cooling vessels with long coiled copper pipes that condense vapour to liquid. Compared with modern condensers they can reduce some copper contact, contributing to a weighty and savoury new-make character. Sherry and other oak casks then provide further complexity during maturation.


Mortlach core single malt whisky range compared


Mortlach's established permanent expressions are the 12, 16 and 20 Year Old. ABV figures below are 43.4% as published by Diageo. Market packaging and bottle sizes differ, and the 14 Year Old Alexander's Way is better regarded as a travel retail expression rather than a fourth standard bottle.

Rare and limited Mortlach whiskies


Midnight Malt 30 Year Old and new collections


Mortlach Midnight Malt 30 Year Old, announced in 2022, combines finishing in Bordeaux wine, Calvados and Guatemalan rum casks. Later experimental lines include the design collaboration Mortlach x Philippe Starck, the Neverbound French oak-finished release and a dedicated global travel retail collection. These are limited or specialist releases, not replacements for the three regular core bottles.


Historic Diageo Special Releases


Diageo has bottled Mortlach in several Special Releases, including The Lure of the Blood Moon in 2022, finished in Tawny Port, Red Muscat wine and virgin oak casks, and The Katana's Edge in 2023 with its own experimental wood influences. Always check the release year and individual ABV; editions vary.


Mortlach 75 Year Old by Gordon & MacPhail


In September 2015 Gordon & MacPhail launched a 75-year-old Mortlach from a first-fill sherry cask filled in 1939. Only 100 crystal decanters were released, at a reported £20,000 suggested retail price. This is a documented historic launch price, not proof of Mortlach's highest-ever auction sale. Gordon & MacPhail previously released a 70-year-old Mortlach in 2010.


Mortlach awards and international availability


Diageo's US retail listing identifies a 2021 San Francisco World Spirits Competition Gold Medal for Mortlach 12. This award applies to that expression and year, not automatically to every Mortlach bottle. Changes in competition results and stock should be verified at the time of publication.

Frequently asked questions about Mortlach


Mortlach is known for a weighty, savoury and complex spirit. Its unusual partial third distillation and worm tub condensers help produce a rich texture quite different from many lighter Speyside malts.


Mortlach uses six stills in a complex scheme that sends different spirit fractions through different paths. The average effective distillation count is often described as 2.81 rather than the standard twice-distilled Scotch process.


The 12 Year Old Wee Witchie is the usual starting point. Its European and American oak maturation balances robust Mortlach character with sweet spice. For more pronounced sherry influence, consider the 16 Year Old.


Yes. Mortlach has been part of the Johnnie Walker blending story since the 1920s and is currently a Diageo-owned distillery. Its spirit has historically contributed to blended whiskies.
