Glendullan
Signatory 100 Proof 2012
Single Malt Whisky
57.1% • 700ml • Speyside

Under the busy canopy of Dufftown, Glendullan has long been a distillery that gets on with things, quietly turning out a dependable Speyside malt while flashier neighbours soak up the attention. It began in 1897 under the guidance of William Williams, an Aberdeen blender and broker, and over the decades it slipped, as so many did, into the larger family of companies that now sit under Diageo’s umbrella.
The place you see today is the product of change rather than romance. A major modernisation arrived in the early 1960s, then in 1972 a new distillery was built beside the old one and run alongside it for a time. Eventually the original site bowed out in 1985, leaving the newer plant to carry the name forward and keep the spirit style consistent.
Glendullan’s public face is often tied to The Singleton, where “The Singleton of Glendullan” was positioned for markets like North America. That role suits it. The distillate tends to be straightforward and friendly, with orchard fruit, soft malt sweetness, and a fresh, lightly grassy edge that keeps things lively without shouting. The stillhouse setup is workmanlike and balanced, with three wash stills and three spirit stills, geared toward producing a clean, repeatable character that plays well in blends and behaves beautifully when given patient time in oak.
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.
