This is way cool. Michigan didn't rank quite as highly as we sometimes like to think - but we're still in the top 10. Check out Ricahrd Florida's break down of how political, religious, and cultural leanings correlate with artisanal beer production.
"The numbers look slightly different, however, when we control for population (see the second map below). Vermont now leads with 3.68 breweries per 100,000 people, followed by Montana (3.23) and Oregon (3.16). Alaska, Maine, Colorado, Wyoming, Washington, Idaho, and Wisconsin round out the top 10. New Mexico, New Hampshire, and Michigan are the only other states to have more than 1 craft brewery per 100,000 people."
