Page 3, *note minor quibble - a hophead is technically not a heavy drinker, it's someone who wants more and more and more hops in their beer. Of course most hopheads are actually heavy drinkers
but I have met the occasional one who doesn't drink that often - though when they do they want a super hoppy beer. And then on the other hand you have super heavy drinkers, like people who drink 12-24 cans a day, but it's all completely unhoppy pisswater like Coors or Budweiser so they're not hopheads.
As someone who's not a really hophead, but I do know a lot of beer, this series is fun - thanks for the scanslates!
Edit: page 11 panel 4 (lower right) is pretty confusing if you don't really know your beer history. Alesmith is in San Diego, modern IPAs were created in Yakima Washington, but the Brut IPA Style was created in San Francisco and that must be what he means here, so maybe instead of 'this beer' 'the Brut IPA'
