New Year's Day Wineries in Napa or Sonoma

Hi, doing a return trip to California wine country with a large group of friends over New Year's, and was curious if anyone had any recommendations for wineries that might be open on New Year's Day. I found the link below, but am curious if anyone is aware of any Sonoma wineries that might be open and/or has any views on the Napa ones. (We know Alpha & Omega quite well, having been there a few years ago and are going back on NYE.)

We tend to like smaller producers (i.e., things not easily accessible on the East Coast) and we are a semi-large group (~10) so need somewhere that can accommodate us. Other wineries we have liked in the past include Unti, Robert Young, Freeman's, Robert Hunter and Lynmar. On this trip we are hitting a few of the bigger producers on NYE, including Joseph Phelps, Clos Du Val, and Clos Pegase.

Thanks!
