Mortlach
First Editions 2009
Single Malt Whisky
53.1% • 700ml • Speyside

Founded in 1823, Mortlach was the first legal distillery established in Dufftown, years before the town became one of Speyside’s great whisky centres. Its early history was somewhat unsettled, with changing ownership and periods of closure, though stability arrived under the Cowie family in the nineteenth century. Alexander Cowie, a physician by training, is largely responsible for shaping the distillery’s famously complex production regime, which remains central to Mortlach’s identity today.
The distillery is best known for its unusual “2.81 distillation” process, a deliberately intricate system involving six stills of different shapes and functions. Rather than following a simple double distillation model, portions of the spirit are redistilled in varying combinations, producing a notably weighty and characterful new make. Traditional worm tub condensers further contribute to this style by limiting copper contact and preserving richer, heavier compounds within the spirit.
For much of its history, Mortlach was highly valued as a blending component, particularly within the Johnnie Walker portfolio, where its dense spirit added structure and depth. As a single malt, however, it has gained a devoted following for precisely those same qualities. Mortlach often displays a darker, more robust profile than many Speyside whiskies, with notes of dried fruit, spice, roasted nuts, and a savoury richness that develops particularly well in sherry casks.
Although modern releases have become more widely available, Mortlach retains a slightly old-fashioned character, both in production and personality. It is a distillery whose reputation rests less on elegance or delicacy, and more on substance, texture, and a quietly uncompromising style.
Founded in 1988 by Andrew Symington, Signatory Vintage Scotch Whisky Company emerged during a period when independent bottling was still a relatively understated part of the Scotch whisky landscape. Symington’s approach was clear from the outset: to source individual casks and present them with minimal interference, often at natural cask strength, allowing the character of both distillery and maturation to remain fully intact. It was a philosophy rooted not in consistency, but in variation, and in the belief that each cask had something distinct to say.
Over time, the company built a reputation for both breadth and depth. Its releases have spanned an extraordinary range of distilleries, from well-known names to those long since closed, preserving liquid that might otherwise have disappeared into blends or obscurity. This archival instinct has become one of Signatory’s defining traits, offering drinkers access to styles and profiles that no longer exist in active production. The acquisition of Edradour Distillery in 2002 added a physical anchor to its operations, while leaving its core identity as a bottler unchanged.
What distinguishes Signatory most clearly is its transparency and structure. Bottlings typically carry detailed information, including distillation and bottling dates, cask type, and outturn, presented without embellishment. Much of the range is released without chill filtration or added colouring, reinforcing a sense of fidelity to the cask. Alongside its single cask releases, the introduction of the 100 Proof range has provided a more structured offering, where whiskies are selected and batched to be bottled at a consistent strength of 57.1% ABV. These releases retain the company’s emphasis on clarity and integrity, while offering a slightly more approachable framework for regular availability, balancing individuality with a degree of continuity.
Across series such as the Un-Chillfiltered Collection, Cask Strength releases, and the 100 Proof range, the underlying principle remains consistent: each bottle represents a moment in time, shaped by wood, spirit, and patience, and presented with a minimum of intervention.
