The main ingredient in cognac is the Ugni Blanc grape variety. This grape is the primary grape used in the production of cognac, and it is grown in the Cognac region of France. The Ugni Blanc grape is known for its high acidity and low sugar content, which makes it perfect for distillation and aging.
The grapes used in cognac production must come from one of six different terroirs in the Cognac region. These terroirs, known as Grande Champagne, Petite Champagne, Borderies, Fins Bois, Bons Bois, and Bois Ordinaires, each have their own unique soil composition and microclimate, which contribute to the distinct flavors and characteristics of the cognac.
Among these terroirs, the grapes from the Grande Champagne terroir are considered the best quality and are often used to produce premium cognacs. The soil in the Grande Champagne region is rich in limestone, which helps to produce grapes with a high acidity and aromatic complexity.
In addition to the Ugni Blanc grape, a small amount of other grape varieties, such as Folle Blanche and Colombard, may also be used in the production of cognac. However, these varieties are less commonly used and are often blended with Ugni Blanc to add complexity to the final product.
It's worth noting that the production of cognac involves a lengthy and complex process. After the grapes are harvested, they are pressed to extract the juice, which is then fermented to convert the sugars into alcohol. The resulting wine is then distilled twice in copper stills to create a clear, high-proof spirit known as eau-de-vie.
The eau-de-vie is then aged in oak barrels for a minimum of two years, although many cognacs are aged for much longer periods of time. During the aging process, the spirit takes on the flavors and aromas of the oak, as well as developing additional complexity and smoothness.
