Produced using the original late-19th century recipe in the heart of French Catalan territory, Byrrh combines a generous, port-like wine and mistelle base with a firm backbone of natural quinine to produce a fruity, refreshing aperitif by itself, with tonic and a twist. In cocktails, Byrrh mixes well with vodka, gin, cognac, tequila, Irish whiskey, and grapefruit. Very nice with bleu cheese.
