Korbel Champagne Cellars is a winery based in Guerneville, California. Since 1882, Korbel has primarily manufactured California champagne, using the méthode champenoise process. In this process, sparkling wine is fermented inside the same bottle from which it is served. The company is a division of F. Korbel Brothers, and also makes brandy and still wine, and imports Prosecco from Italy.

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.
