Proper No. Twelve Irish Whiskey is a premium triple-distilled blend of fine grain and single malt Irish whiskey, founded by MMA champion Conor McGregor. Crafted at the Bushmills distillery in Ireland, it is aged for four years in bourbon barrels, producing a smooth, approachable spirit with pronounced notes of vanilla, honey, and toasted wood.

The whiskey is bottled at 80 proof (40% ABV) and is distilled entirely in Ireland following traditional Irish whiskey production methods. Its triple-distillation process results in a notably smooth character that distinguishes it from Scotch and American whiskeys. This 1.75L format (a handle) contains the equivalent of roughly 40 standard 1.5 oz servings, making it well-suited for entertaining.
