Cognac is a variety of brandy named after the commune of Cognac, France. It is produced in the surrounding wine-growing region in the departments of Charente and Charente-Maritime.

Brandy is a liquor produced by distilling wine. Brandy generally contains 35–60% alcohol by volume and is typically consumed as an after-dinner digestif. Some brandies are aged in wooden casks. Others are coloured with caramel colouring to imitate the effect of aging, and some are produced using a combination of aging and colouring. Varieties of wine brandy can be found across the winemaking world. Among the most renowned are Cognac and Armagnac from south-western France.
