With a total area of 230,000 acres (93,078 ha), 38,000 acres (15,378 ha) of which are planted to wine grapes, this region in the heart of the San Joaquin Valley region of the Central Valley produces 10% of all wine grapes grown in the state of California. Modern grape growing practices have shown that this region can produce very high quality wines. The region has seen tremendous growth and success due to the shift from high-volume production to high-quality production.
In years past, many of the grapes grown in Madera were used for the production of low-priced wines. Today the grapes are shipped to producers of wines throughout the state, including Napa and Sonoma. The wineries located in the region produce award-winning wines from the large variety of grapes grown in the Madera AVA designation.
