Sherry-Cask American Single Malt Whisky

American Single Malt whisky (100% malted barley distilled at a single US distillery, per TTB American Single Malt category) matured in former Spanish Sherry casks (PX, Fino, Oloroso). The sherry maturation imparts dried-fruit, hazelnut, leather, and toffee notes that are flavor-load-bearing in stirred and sherry-leaning cocktails (Rob Roy variants, Boulevardier substitutions).
