Sonoma wineries-any free tasting wineries?
If you are up by Frick, you can figure that about 75%+ of the places you would just stop in for a look-see would have free tasting. That area has become my first choice of wine tasting/touring. Even the Geyser Peak tasting room (large for that area) is a calm respite (also complimentary) as compared to most anything on or near Highway 29 in that next county over.
personally, i think paying for a wine tasting is silly when you can just drive through russian river and dry creek valleys, beautiful little winding roads, and taste for free at charming little family-owned tasting rooms that only fit a handful of people.
My favorites in RR and DCV:
Dutcher Crossing (my #1)
Rosenblum (downtown Healdsburg)
i know that one or two of these have a small fee that is refundable upon purchase (i think dutcher crossing, maybe rosenblum), which kind of defeats the question i'm answering, but i always end up buying at least a bottle.
Are you looking for Sonoma valley or Sonoma county?
Havn't been down Hwy 12 in some time, but there are a fair number of places that don't charge in Dry Creek. David Coffaro (might need an appt) doesn't charge, nor does Unti (again, just call first). Rosenblum doesn't charge, and I don't remember Ridge charging or Preston. Christopher Creek is another good stop.
