SJV Grape Production
California’s climate has many advantages over other states in the US and countries when it comes to growing grapes. In general, winters are moderate to mild with precipitation ranging from 3 inches in the south to 40 inches in the northern part of the state. The growing season is long with few rain events experienced during the summer. Temperatures range from cool and mild nights and warm days in the north coast to a hot, dry and low humidity climate found in the San Joaquin Valley.
Grape growers in the Sothern San Joaquin Valley (Fresno, Tulare, Kings and Kern counties) are able to grow grapes for raisin, table, wine and juice concentrate. Annual precipitation ranges between 11 inches (Fresno) to 5 inches (Kern) so vineyards need supplemental irrigation. The lack of summer precipitation and warm days is perfect for growing grapes. The area is home to 95% of the states raisin and table grape vineyards and 70% of the states wine grapes.
