I'm posting this in MO instead of IL because Belleville is just across the river from St Louis, but 290 miles from Chicago.
Anyway, the annual Learn to Homebrew day is November 3, 2012. There's an event at Dave's Homebrew and Gourmet in downtown Belleville. It's a few blocks from the Belleville Downtown Metro Link station, or a 20 minute drive from downtown StL. The event will be held outside, behind the store. Several folks including myself are bringing beers for the local experts to taste (I need to hurry up and bottle my North English Brown). Should be a lot of fun!
122 E. Main, Belleville IL 62220
Recent brews: Amber ale w/ honey malt, Dunkelweizen, Oktoberfest, Alt, Kölsch, English Brown, Rye IPA, Amarillo IPA. 55 gallons so far in 2013.
