Suze is a French aperitif known for its distinct bittersweet flavor profile, primarily derived from the gentian root. Gentian, a plant native to the mountainous regions of Europe, is valued for its digestive properties and its intensely bitter taste. Suze was first introduced in the late 19th century, around 1889, and has since become a staple in French bars and homes, often enjoyed as part of various cocktails or served simply with tonic or as part of a spritz.

The aperitif is characterized by its golden yellow color, which it traditionally gets from the natural coloring of the gentian root, although some variations may use additional coloring agents. Suze's flavor is complex, featuring not only its hallmark bitterness but also herbal, citrus, and floral notes, making it a versatile ingredient in mixology.

In addition to gentian, Suze may contain a blend of other botanicals and ingredients, which contribute to its unique taste and aroma. It is relatively low in alcohol compared to many spirits, usually around 15-20% ABV (alcohol by volume), which makes it a popular choice for lighter, aperitif-style cocktails.

Suze has experienced a resurgence in popularity beyond France, particularly among bartenders and cocktail enthusiasts around the world, who appreciate its unique flavor and its ability to add depth and complexity to drinks.
