Fernet is a category of aromatic, bitter herbal liqueurs originating from Italy, with the most iconic brands including Fernet-Branca, which was established in 1845 in Milan. Fernet is traditionally crafted by infusing a blend of herbs, roots, spices, and botanicals—often including myrrh, rhubarb, chamomile, cardamom, and saffron—into a base of neutral spirits, then aging it for added complexity.

Fernet is celebrated for its intense, bold flavor profile, with pronounced bitterness balanced by subtle sweetness and aromatic depth. It is traditionally consumed as a digestif to aid digestion, but it has also become popular as a cocktail ingredient, especially in countries like Argentina, where it is mixed with cola. The category appeals to enthusiasts who enjoy complex, challenging spirits with a rich heritage, artisanal production methods, and a distinctive, memorable taste.
