Glenrothes 27 years is part of the Cask Strength Collection by Signatory Vintage. The whiskey matures into a hogshead (cask 19015) and has a print run of 247 bottles. Expect an oily scent with notes of brown sugar, chocolate, vanilla and lemon. The palate is full and sweet with notes of raisins, plums, malt and chocolate. In the background note delicate herbs. The finish is long, some sweet and reminiscent of oak.
