There was a long article in today's (Sunday's) Santa Rosa Press Democrat about the effects of the fire on various wineries in Sonoma and Napa counties. The link is www.pressdemocrat.com.
It seems that the fire concentrated itself in a couple of areas: The first on the east slope of Howell Mountain, and the second along Hwy 128 just southeast of Calistoga.
The Glass fire doesn't seem to have done much damage in Sonoma county, though Ledson came close to burning (but it didn't), and some vineyards in the Kenwood area seem to have had some damage.
