These guys have been around for awhile, and locally don't get enough credit. They are putting out some fine brews, and now with better distribution, the beer you get in a store is always fresh. Also, with the new Iowa laws, they have started making higher alcohol beers as well. I was at their taproom last weekend and tried their 8.5% weizenbock on tap...amazing. Complex grains, not to sweet, and way too easy to drink, especially in 90 degrees and 100% humidty. If I stayed there any longer, I would've gotten pulled over, and of course my wife wouldn't have been happy. So I did what every responsible beer drinker does, took some to go.
Just off the beaten path if you Travel I-80 through Iowa. Tasting room and brewery are located in Main Amana in the Amana Colonies. A nice little tourist area and historical site of a religious commune. I enjoy their "Iowa Pale Ale"
