PietroButtita has been making wines up in LakeCnty for the Rosa d'Oro label for a number of yrs. For the last few yrs, he's been making his wines under the PrimaMateria label. After a long/convoluted process, Pietro has finally got his tasting room in Oakland open in the Temescal area of Oakland. All of his wines are available there to taste.
Pietro is also a very talented chef and I believe there are also plans to do some food events eventually.
Anyway, for EastBay folks, probably worth stopping in for a visit. I've not been yet, but I like Pietro's wines in general.
