Glendalough Double Barrel

Glendalough Distillery (Mark Anthony Brands)

The double barrel treatment here is a study in how fire shapes wood, and wood shapes whiskey. The first-fill bourbon barrels — charred by fire before they ever held spirit — give the Glendalough its vanilla and caramel backbone. The Oloroso sherry casks — toasted to a different specification — add dried fruit and chocolate complexity.
