It's a beautiful brewery, made to look like an European castle or chateau. They also took the tops off of some old copper mash tuns or brew kettles to sit over the top of their stainless steel tanks to enhance that appearance. However, appearances, like words, can be deceiving. I also toured Capital Brewery the same day, where they actually use a copper tun and kettle. Looking through the door of the kettle, the difference was apparent.
I still have to get out to New Glarus and do that one. Their brewery does look beautiful in the pics, and I'm very familiar with topography in the area. Southwest Wisconsin reminds me a lot of Southern Belgium near the border with Luxembourg with the rolling hills and stone farmhouses. We used to camp at nearby Yellowstone Lake every summer.
If you are up in that area again you should try Ale Asylum and the Great Dane Brewpup. Great Dane has several locations in the area, be sure to try the one on the ismuth.
