Expect fresh brews from Lagunitas, Trumer Pils, Linden Street Brewery, Santa Cruz Ale Works, Thirsty Bear, and others, in a giant covered beer hall. Sip away in the biergarten while the kids enjoy their own root beer-filled sippy cups; there's a kids' area with Root Biergarten for them to go wild. An intriguing German-style Homebrew Competition (in conjunction with the Mad Zymurgists Club) is scheduled. Entries were collected in San Leandro, Livermore, and Berkeley last month. Other attractions include music, pub food, and -- because this isn't the early 1900s but it is the Bay Area -- an eco fair.
