The folks at GlenAllachie (including the legendary Billy Walker) have gone and made a blended Scotch whisky! White Heather 21 Year Old is made with whiskies from Speyside, the Highlands and Islay, aged in first-fill American barrels, sherry butts, and second-fill barrels and hogsheads. The blend also enjoyed three years of additional maturation in Pedro Ximénez puncheons, Oloroso puncheons, and Appalachian virgin oak casks. The name comes from a blended whisky brand that was discontinued back in the 1980s, which was acquired by The GlenAllachie Distillers Company in 2017.
