The South Coast Southern California region begins in Ventura County just north of Malibu and stretches all the way south through the Temecula Valley to San Diego County. This region’s wineries are tucked in canyons and valleys while some have tasting rooms right along the Pacific coastline. Besides growing their own winegrapes, many South Coast winemakers source their grapes from other California regions. The wineries here will greet you with genuine Southern California hospitality.
