Sonoma and Napa Organic Wine Grapes Decline from 2015 to 2016

The number of certified, organically grown wine grapes dwindled in both Napa and Sonoma counties from 2015 to 2016, according to recent crop reports.

Certified organic acreage in Napa dropped from 3,897 acres in 2015 to 3,210 in 2016, a drop of 677 acres or 17.6%. In 2015, Napa's organic acreage accounted for 9 percent of total vineyard acres; by 2016, that figure dropped to 7.4%.

On the other hand, the use of glyphosate used in Napa on wine grapes declined from 2015 to 2016 from 53,808 pounds on 37,566 acres to 47,524 pounds on 32,921 acres, a sign that fewer wineries are using the herbicide, a designated carcinogen in California.

Sonoma, a sometimes hotbed of organic dairy, egg, fruit and vegetable crops, also saw a decline from an already small number of organic wine grape vineyards during the same period. 

In 2015, Sonoma county had 1,578 acres of organic grape vines, which decreased to 1,405 acres in 2016, a decline of 11%. About 2 percent of the wine grape vines in the county are certified organic (in comparison to Napa, where about 7.3 percent are certified organic).

In 2016, Napa wine growers used 65,132 pounds of glyphosate. Sonoma growers used 74,281.
