Part of the refreshed line-up from ‘the Beast of Dufftown’, this expression from Mortlach has been matured exclusively in American oak ex-sherry casks, with a percentage of refill wood, and bottled at 43.4% abv. The oldest expression in the range, this 20-year-old is affectionately named ‘Cowie’s Blue Seal’, in tribute to one of the very first bottlings of Mortlach dating back to 1909.
