There are a number of eateries in San Diego that have started reserving taps for wine kegs rather than beer, and like the brew that San Diego???s beer snobs have grown accustomed to, this is craft wine, the real deal, and the fact that it???s in a keg is a good sign rather than a red flag.Take the taps at The Linkery, Jay Porter???s North Park eatery that focuses on local and sustainable foods.
