What is Lillet recognized as?

Lillet is recognized as a mild quinquina that originates from Bordeaux, France. It is a fortified wine that is flavored with a blend of herbs and fruit, resulting in a refreshing and aromatic beverage. The term "quinquina" specifically refers to a style of fortified wine that is infused with quinine, derived from the bark of the cinchona tree, which gives it a slight bitterness that pairs well with other flavors.

Lillet is known for its use in cocktails or served chilled as an aperitif, making it a popular choice for summertime drinks. The Bordeaux region is historically significant for producing a variety of wines, and Lillet has carved out a niche by combining traditional winemaking with herbal infusions, contributing to its unique flavor profile.
