Mortlach 8 Year Old Douglas Laing Provenance 2008 Single Cask DL11257 PRV1205 (2016) 70cl

Mortlach’s main claim to fame, production wise, is as the home of the most fiendishly complex distillation regime in Scotland.

The wash (from clear wort and long fermentation) is split between three wash stills; No. 3 wash still and No.3 spirit still work in tandem and as per normal.

The low wines from wash stills No. 1 and 2 is, however, split into two parts. The first 80% of the run is collected as the charge for spirit still No. 2. The remaining 20% (called weak feints) forms the charge for spirit still No.1 otherwise known as ‘The Wee Witchie’. This distils the weak feints three times with only the heart of the final run being collected. It all adds up to the new make spirit having been distilled 2.81 times.

In addition to this, all the stills are run relatively speedily with no air rests to rejuvenate the copper and all lyne arms running into cold worm tubs. The result of this complex regime in a copper-starved environment is a building up of sulphur and ‘meatiness’ in the new make spirit, with the ‘dud runs’ on the Wee Witchie providing an extra meaty boost. Although it is aged in a mix of casks, Mortlach’s weight makes it an ideal partner with ex-Sherry casks.

While other meaty spirits are made [most notably Benrinnes and Dailuaine] none have Mortlach’s weight, meaning that this is a highly-prized base note for blends. As a result, there has been little stock available for single malt bottlings bar the occasional independent bottlings (most notably with Gordon & MacPhail) and small batches of a 16-year-old in Diageo’s Flora & Fauna range. Mortlach seemed destined to remain a cult malt.

In 2014, however, that changed with the launch of a four-strong range: Rare Old, Special Strength, (both no-age-statement), 18-year-old, and 25-year-old.

Mortlach was the name of the original village which sprang up around the abbey of the name, founded by Saint Moluag in the 7th century. With the building of Dufftown in 1817 the old name fell in abeyance – apart from the distillery.

The distillery was the first to be licensed within Dufftown, being founded by James Findlater, Donald Mackintosh and Alex Gordon in 1823. It passed briefly into the hands of the Grant brothers of Glen Grant fame who gutted the buildings and used the equipment for their distillery in Rothes.

It was George Cowie and his son Alexander who, from the 1850s on, recommenced whisky production and steered Mortlach to a pre-eminent position as a blending malt.

Although no-one is sure where the unique distillation regime originated, its adherence to richness and weight singles Mortlach out as one of the distilleries with a robust belief in the older ways of making whisky.

It remained in the Cowie’s hands until 1923 when it became part of John Walker & Sons and from there via DCL into Diageo.

In 2014, it was announced that a mirror image of the existing distillery would be built which, when completed, will double total capacity.
