Letherbee's Barrel-Aged Absinthe draws its caramel hue from a six-month stint in unused, charred-oak casks. A straightforward white absinthe recipe mellows in the aging process, softening the anise notes to let sumptuous floral and spice layers resonate. Besides the color, the full-sized barrels also imbue the Absinthe Brun with toasty hints of vanilla and caramel. Bottled at 126 proof, the spirit-forward drink is an addictive sipper that can also add depth to a variety of cocktails.
