In 1923, John Walker and Sons acquired the distillery from then owner Alexander Cowie and two years later, they in turn became part of Distillers Company Limit- ed, and subsequently Scottish Malt Distillers and then Diageo. There have been a few official releases as well as a selection of independent bottlings.
Mortlach had its own floor maltings until 1968 and remains one of only a handful of distilleries still using wooden worm-tub condensers to cool their spirit. The dis- tillery is also one of only three distilleries using ‘partial triple distillation’ as also practised at Benrinnes and Springbank. The house style is full, rich, and robust, with the spirit showing a great affinity for sherry wood, resulting in some magnifi- cent older bottlings. (17-year-old Whisky offered by Adelphi)
