Colombard
Colombard is the workhorse white wine grape of California's central valley. It produces very good wines of high acidity and good flavor. Colombard (often called French Colombard) blends well with Chenin Blanc and is a usual component of most California non-varietal everyday white wines. Grown in many regions of France, including Cognac and Armagnac and used in many of the ordinary table wines of southern France.
