Anyone buy beer in growlers? I only have a quart growler? We have some interesting laws in California. Growlers can only be filled at the site of a brewery, although a few brewers have "duplicate licenses" for tasting rooms which allows growlers to be filled at satellite facilities. I mentioned the Sierra Nevada Torpedo Room in Berkeley, although another local brewery (Half Moon Bay Brewing) is doing something similar in Berkeley.
Sierra Nevada is kind of strict about filling too. They'll only fill their own growlers. I've seen someone bring in another one and was told they didn't do it. State law allows any growler to be filled, but any markings of another brewer must be covered up and a tag/label attached with the brewer and specific beer. I understand that lots of brewers don't want to do it.
