Where Are California's Organic Vines? CCOF Stats Shows 4 Percent of State's Wine Grape Vines are Organic–A Quarter Are in Napa

Newly released data from CCOF, the state's largest organic certifier, shows that there are 23,187 acres of wine grapes in the state that are certified organic compared to industry statistics of a statewide total of about 550,000 acres of bearing wine grapes. 

(Ridge Vineyards, which uses Organic Certifiers, has about 200 more acres of organically grown wine grapes.)

Compared to Europe's major wine growing countries–where 18 percent of wine grapes are certified organic, California's numbers are pretty low–just 4 percent. That's about one fifth as much percentagewise as the three leading organic wine grape countries in the EU.

In 2016, CCOF certified 10,644 acres of organic wine grapes, which means acreage has more than doubled since 2016. 

Napa Has 24 Percent of State's Organic Wine Grape Acreage

Of the wine grapes in California that are certified organic, one county has 24 percent, or about a quarter of all of the certified organic wine grapes in the state. Napa has 5,550 acres of certified organic wine grapes. That amounts to 12 percent of the county's wine grapes overall.  

Sonoma Organic Wine Grapes Are 11 Percent of State's Organic Wine Grape Acreage

In comparison, Sonoma has 2,537 acres of organic wine grapes (according to CCOF) out of a total of about 60,000 acres of wine grapes, according to government officials. That is about 4 percent of the wine grapes grown in Sonoma.
