About
Dufftown's first distillery and one of the most distinctive in all of Scotland, known for its legendarily complex '2.81 times' distillation process -- a partial triple distillation using 6 mismatched stills of different sizes and shapes. This 'Mortlach way' produces a big, meaty, intensely concentrated spirit nicknamed 'the Beast of Dufftown.' Long a blender's secret (prized for Johnnie Walker), Diageo launched it as a premium single malt brand in 2014.
Production Details
The Mortlach Tale
In 1823, when James Findlater chose a plot of land beside the River Dullan in what would become Dufftown, he couldn't have known he was founding what locals would later call "the Beast of Dufftown." He simply knew the springs flowing down from the Conval Hills ran clean and cold, and the barley grew well in Speyside's gentle climate. Mortlach became Dufftown's first distillery, a pioneer in a town that would eventually house seven.
But Mortlach's early years read like a cautionary tale of Scottish enterprise. Ownership passed through hands like water through Highland peat—Findlater to Macintosh and Gordon, then to Robertson for £270, then to the Gregory brothers. By 1837, the Grant brothers of Aberlour had joined the fray, but production had ceased entirely. For years, the buildings served as a church and brewery, the stills silent, the mash tun cold.
Everything changed when George Cowie arrived in 1853. Where others saw complexity as chaos, Cowie saw opportunity. When his son Alexander joined in 1896, they expanded from three stills to six—but not in any conventional way. The Cowies installed stills of different sizes and shapes, creating what became known as Mortlach's "2.81 times" distillation process. It wasn't quite double distillation, wasn't quite triple—it was something uniquely their own.
Today, those six mismatched stills still stand in the Dufftown stillhouse like a copper orchestra of different instruments. Three wash stills and three spirit stills work in careful choreography, some spirit cycling through multiple vessels, creating a partial triple distillation that defies easy explanation. The Douglas fir washbacks hold fermenting wash for either 55 hours or 110 hours—short and long fermentations running side by side. Ancient worm tubs cool the spirit vapors, coiling copper serpents that add their own character to every drop.
The 12-ton full lauter mash tun processes 48 mashes each week, fed by those same Conval Hills springs that attracted Findlater two centuries ago. The water carries minerals from granite and peat, the geological signature of this corner of Banffshire written into every bottle.
When John Walker & Sons acquired Mortlach in 1923, they understood they'd bought something extraordinary. For decades, this intensely concentrated spirit became the backbone of Johnnie Walker blends, a closely guarded secret among master blenders. They called it "the Beast" for good reason—few single malts could match its power and complexity.
Under Diageo's stewardship, Mortlach finally stepped into the light. The 2014 launch as a premium single malt brand revealed what blenders had known for generations. Today, expressions like the 12-year-old Wee Witchie and 20-year-old Cowie's Blue Seal carry forward that tradition, each bottle a testament to the stubborn genius of mismatched stills and the 2.81 process that remains unchanged.
From its stillhouse windows, you can see across Dufftown to the other distilleries that followed Mortlach's lead. But none sound quite like this place—the particular rhythm of six stills working in calculated discord, the Beast of Dufftown still breathing fire after two hundred years.
