One flaw I will take issue with in the 'microbrew capital' list is that it's somewhat irrelevant when you take into account distribution. Hill Farmstead and The Alchemist will make anyone's top ten yet they are not in catchment for Burlington VT.
I'm also truly surprised not to see Boston show up anywhere on this list no matter how I tweak the inputs. There are multiple dozens of breweries within the metro area.
Without question, Portland ME is a mecca. But MA & VT cities don't seem to make the cut while clearly over representing in the 'top' lists?
I'll take this list with a pinch of Irish Moss to damp it down a little.
Here's one of the more compelling brewery reports I've seen recently
