Korbel is the only major Brandy maker in the US which still maintains total control of its own wine making, brandy distillation, barrel aging, blending, and bottling. Our own people, in our own facilities, closely control every step of the brandy making process. We crush and ferment only the finest California brandy grapes to make our base wines. The young wines are then distilled in a copper lined still to ensure the highest level of purity and flavor. The fiery heat of the water-white new distillates is slowly mellowed in one of our 30,000 small, American oak, barrels.
