This is when all of the Livermore wineries open with craft and food vendors, tastings and a chance for you to do all of your gift shopping.  Most wineries have a modest tasting fee (although there is no fee to come and shop) and many wave that fee if you bring a nice gift for Toys for Tots.  This event is so much fun that I fly here from the farm just to participate, who can say no to Steven Kent wines and holiday shopping all at the same time?  I will be in the barrel room at the Steven Kent Winery from noon until 5 PM both days.  5443 Tesla Rd in Livermore.
