At least six wineries in Northern California have seen severe or total damage from the fires ravaging Sonoma County, according to a CNBC news report.

The report states 22 fires have blazed through more than 170,000 acres in California, damaging approximately 3,500 homes and commercial properties. At least 17 people have died with many more reported missing.

In Napa Valley and Sonoma County, five wineries have sustained significant or total losses. Several other wineries have reported damage to their buildings or vineyards. The Paradise Ridge Winery in Sonoma is reported to have been completely destroyed. 

The Napa Valley Vintners and Sonoma County Vintners believe the numbers could change, as not all winery owners have been able to assess damage while the fires are still burning.

Harvest season is underway in both Napa and Sonoma’s wine country, but the Napa Valley Vintners estimates 90 percent of the grapes were already picked before the fires started burning during the past weekend. The grapes remaining on the vines are mostly Cabernet Sauvignon, but the association does not expect them to be harmed by the smoke, as that variety of grapes is thick-skinned.

It remains to be seen what the fires’ economic impact will be on the region’s wine industry. It is also unclear how the smoke will affect this year's wine product.
