Mortlach was established in 1823 in the wake of the Excise Act. Built on the site of an older illicit distillery Mortlach was the first legal distillery in Dufftown which is the epicentre on Speyside. Now under the ownership on Diageo it plays a very important role in some of the world’s finest blends. This is due to the oily meaty character it has and the mass production. Known as “The Beast of Dufftown” this character is due to its special distillation process resulting in a spirit which has been distilled 2.81 times. Mortlach is again making its mark as a single malt with last years Diageo Special Release bottling selling out in record time.
