Interesting article by JonBonne naming Steve&Jill Matthiasson the Chron's Winemaker of the Year:
SFChron:Winemaker of the Year
I've not yet tried any of their Tendu wine that is made from purchased grapes from YoloCnty.
The Matthiasson wines that I've had are interesting & well-made, but never going to get big scores out of Monktown.
Their one Refosco I've tried (probably the only true Refosco dal PeduncolaRosso in Calif) was as good as any I've had from Friuli.
