Couvreur Sour'hum Rum 50.5% 700ml

Michel Couvreur (1928–2013) was Belgian-born and trained in the wine industry — work that drew him to Burgundy in the 1950s. In 1964 he moved to Scotland and took up employment in the Scotch whisky industry, where he developed what would become the foundation of his life's work: a strong preference for malt whisky aged in ex-Sherry barrels (particularly Pedro Ximénez), and a dim view of the bourbon-barrel-finished norm that defines most Scotch. In 1978 he returned to Burgundy and set up an independent whisky operation in the village of Bouze-lès-Beaune, just outside Beaune in the Côte de Beaune.

The Couvreur cellar in Bouze-lès-Beaune is unconventional: behind stone, ivy-draped walls, the property contains 150 metres of natural-spring tunnels — once a wine cellar — that now hold whisky casks ageing under cool, humid Burgundy conditions rather than maritime Scottish ones. Couvreur sourced unaged spirit from Scottish distilleries (he never named them publicly, preferring 'Scotch' to a single distillery designation), shipped it to Burgundy, and matured it in ex-Sherry casks for periods ranging from 6 to 40 years. He even grew Bere Barley — the oldest Scottish barley variety — in Orkney for use in his commissioned distillations.

Couvreur's central conviction — that '90% of a whisky's quality comes from the barrel, only 10% from the distillation' — runs against Scotch industry orthodoxy that emphasises distillery character and provenance. His whiskies are accordingly identified by ageing profile (Vintage, Single Malt, Bere Barley) rather than distillery. Couvreur died in 2013; the operation has continued under his successors. The current line includes the Vintage releases (single casks at varying ages), the Blossoming and Cap a Pie blends, the Clearach (Sherry-cask single malt), and the Bere Barley releases.
