I am really becoming a fan of this one.
Definitely a flavorful, 100% sherry single malt. Does anyone have an idea of which distillery this could be? Maybe it's Glenfarclas (kind of like a trick question), but other distilleries with a lot of sherry casks would be ones like Glenrothes, Glendronach and Aberlour. Damn speyside malts for being so hard to distinguish.
