Headed to Sonoma

CorTot thought this was worth mentioning said

The Mrs. and I are headed to Sonoma for a much needed long weekend away from all the things. Its been quite a while since we were last there and while there are some absolute must stops.

Is there anything off of the beaten path that has come up in the last 5 years or so that anyone would highly recommend? (Don’t worry about style of wine we are all over the place in that regard.)
