Local is not better. As I wrote at Joe's, a steaming warm cow patty is both local and fresh. Local does not mean the brewer is better or even admirable. He might be the local abusive businessman or the slacker kid who lets health and safety standards slip. Their beer can really suck. Suck so bad all you can do is post oblique warnings.
As the Beer Nut noted, we've done this one before. I wrote this coming on about five years ago now. Velky Al makes a good point that little beer is actually made of local stuff. Craig dissected today's question concluding "all beer is local to somewhere" which is about as smart as I am ever going to be even the second time around.
