Cognac is a type of brandy that is named after the town of Cognac in France where it is primarily produced. It is made from specific varieties of grapes that are grown in the Cognac region of France and distilled twice in copper pot stills. Cognac is then aged in oak barrels, which imparts a rich and complex flavor profile with notes of oak, vanilla, and caramel. Cognac is typically enjoyed as a sipping spirit and is often served in a snifter glass to enhance its aroma and flavor. It is also a common ingredient in classic cocktails such as the Sidecar and Brandy Alexander. The age of the cognac is indicated by the labeling, with VS indicating a minimum of two years of aging, VSOP indicating a minimum of four years, and XO indicating a minimum of ten years.
