I just came back from a visit to San Fransico and went on a tour of the Anchor Steam Brewery. What a great experience, oh yah the free beer was pretty good also.
Being a homwbrewer for several years, I finally was able to see how the big boys do it. I recommend to anyone who may get a chance, see if your local brewery offers any tours. I found it a great experience and learned a few things.
If you drink. don't drive. Hell, don't even putt!
