As you have certainly noticed, beer companies have a long and not entirely dignified history of employing (or exploiting) breasts to sell their products in ads. Since 2000, however, some breweries have turned this partnership to a more noble cause, this time exploiting  beer to help breasts, or at least help fund breast cancer treatment. About 80 breweries will join host Marin Brewing Company on Saturday for Breastfest 2013 at the Fort Mason Center Festival Pavilion in San Francisco from 2 to 6 p.m. Tickets are $50 in advance and $60 at the door, with proceeds benefiting the Charlotte Maxwell Complementary Clinic, which offers alternative medicine treatments for low income cancer patients in San Francisco and Oakland.

Local standouts include Lagunitas, Bear Republic, 101 North, Anderson Valley, Ace Cider, Napa Smith, St. Florian’s, Russian River, Third Street Aleworks, North Coast and Moonlight. There are lots of good ones from around the state, including Stone, Sierra Nevada, and some smaller interesting ones such as Elevation 66, Hangar 24, and Six Rivers. There are even some brewers from farther afield, such as Maui Brewing, Big Sky, Ommegang, and Abita.
