Well, if you read various media reports, all of California's vineyards blew up and then fell into the ocean. Anybody with winemaking experience was killed. There are no grapes left west of the Rockies. I hope you like Manischewitz and Wild Irish Rose.
In reality, a few wineries were tragically destroyed. Quite a few vineyards had minor damage ranging from a few vines fried on the perimeter to burned end posts and melted driplines. Those are being repaired as we speak. A significant amount of grapes went unpicked due to smoke exposure (about 20% unpicked in Napa and Sonoma). A small percentage of those that were picked had low levels of smoke contamination. You will never taste those. Meanwhile, 2018 and 2019 were record large harvests in the face of flat demand growth. So, in terms of supply, everything is just about in balance. People are already bottling some of their excess 2019, or preparing to extend their short 2020 with it (up to 15% of the blend can be a different vintage).
It has been, apropos of 2020, the most trying harvest ever across the West coast (OR and WA too). But the rumors of the wine industry's death are greatly exaggerated.
EDIT: For those who don't know, I am a consulting winemaker living in Sonoma County. Our clients span the country, but a major focus on the West coast.
