There is a brand-new tasting room in the Los Angeles area--as a matter of fact, it's the only tasting room in Los Angeles.
The tasting room of the D'Argenzio Winery of the Russian River Valley in Sonoma County is located in Burbank, CA.
Fantastic pinot noirs, zins, cabs, and merlots!
The tasting room is open to the public Thursday-Sunday (Friday and Saturday nights are especially fun!) And you get to taste for free! Get a glass, and hang out with friends. The winemakers are there, and they really explain the wines well.
