A couple of years ago a team of crack Glengoyne tasters locked themselves in a room with several dozen Glengoyne 21 Year Old samples drawn from European Oak casks which had been soaked in Oloroso sherry prior to filling. Several hours later they emerged blinking into the daylight, triumphant. The result speaks for itself. Uncork a bottle and brace yourself for a riot of red apples, toffee, honey, oak, sherry and cinnamon.
