Byrrh is a French quinquina created in 1866, known for its red, wine-based formula flavored with cinchona bark and other botanicals, resulting in a sweet, fruity flavor with a slightly bitter finish. It is enjoyed on its own, on the rocks, or as an ingredient in cocktails mixed with spirits like vodka, gin, or cognac. While sometimes compared to vermouth, it has a fuller body and a unique profile that includes notes of dried fruit, spice, and a hint of bitterness.
