The only place to get brewing supplies is at a place called Friar Tucks. It is a liquor store chain in the area. Thay have your basic stuff, small bags of grain, extract, kits and basic equipment. Also if you go check out the walk in cooler. That is where they stash their liquid yeast and hops. Also they have a fairly large selection of craft beers and you can do a mix a six for $10, but it is limited to certain bottles not already packaged in a sixer. I always make sure to hit the place up when I go just to grab up some dry yeast and small things I might need. Their turnover isn't too bad from what I can tell. Bloomington/ Normal has several brewers in the area.
