Argentinians mix it with cola, San Franciscans take it with a ginger ale back, and Italians sip it neat.

Wherever you are in the world, one thing is certain—Fernet is not going away. With a history that spans centuries, this amaro is the kind of niche sipper that inspires obsession: since the drink’s herbal (and usually secret) formulations continue developing in the bottle, obsessives are inclined to seek out an array of blends and vintages.

At 70 proof, Letherbee’s freshly refined take on the signature digestif is smooth, perhaps startlingly so. The prominence of saffron evokes popular Fernets, but supporting notes of rhubarb root and myrrh gum scaffold the palate as to not let bitter notes overpower. Spearmint and eucalyptus lend a subtle, pleasant mentholated finish.

Given Letherbee’s penchant for balanced flavors, this Fernet is versatile—shoot it, sip it after a meal, add it to coffee, or mix it in a complex cocktail.
