Southern California has six AVAs (American Viticultural Areas) in our practical sourcing range: South Coast, Temecula Valley, San Pasqual Valley, Ramona Valley, Antelope Valley, and Cucamonga Valley. The region also includes substantial non-AVA acreage in Riverside, San Bernardino, and northern San Diego counties. Total acreage is small by California standards; quality, at the upper end, is high.
Climate
Mediterranean. Dry summers, wet winters, marine influence within twenty miles of the coast, with substantial day-night thermal swing in the inland hills. The climate is closer to southern France and northern Spain than to Napa or Sonoma. The Rhone and Spanish varietals that thrive in those regions also thrive here.
Soils
Variable. Decomposed granite at many of the hillside sites; sandy loam in the valleys; volcanic and limestone at a few specific sites. The soil variation across short distances is significant, and the small grower can find a site that suits a specific varietal well.
Acreage
Total Southern California wine acreage is approximately 4,000 acres, against Napa's 45,000 and Sonoma's 60,000. The small acreage limits both supply and visibility. Most of the wines stay regional. Most consumers outside the region have not encountered them.
Why this matters for the club
Limited supply plus distinctive varietals plus marine-influenced quality means the region's best wines are largely unavailable to the chain retail consumer. The club's sourcing rule means we can access them. The relationships with growers are direct. The wines reflect both the region's specific character and the small-acreage grower's specific attention.
