Spent my vacation doing a mini-brewery tour in Wisconsin.
Hit up Sprecher... if you're in the Milwaukee area, take the tour - for like $10, you get a tour, a collectible glass and I think 5 decent samples of their beer and unlimited samples of all their soda. Very impressed with the operation and more importantly the beer. Their Octoberfest was good, but the real find is the Piper's Scotch Ale which is unlike any other scotch ale I've ever had... smooth and only about 8%. Also discovered Sprecher has an additional line called, "Chameleon" where they brew outside of their comfort zone. Not all were hits, but the Hops on Top (I think that was the name) was really good.
We also went to a brew-pub in the Madison-area called, "Vintage Brewing Co." - wasn't a fan of any of their beers, but the food was fantastic. I've run into a few of these kinds of places that try really hard to brew great beers but just fail when it comes to their food. With that said, they did have some interesting options, like a dark IPA that was molasses. I could see how some people would really enjoy it, I just felt it had too many things going on and fighting for dominance on my tongue. Go for the beer, stay for the food.
We had also planned to hit up New Glarus, but alas - it wasn't so. The GPS couldn't find it (or rather kept telling us it wasn't where it said it was), so we went without. I'll probably have to stop up in Kenosha at some point to pick up some as don't think they don't sell across state lines.
