You'll get to taste three of Dovetail's beers during this lengthy (and super-informative) tour, but the most interesting moment comes when participants are asked to sample three different types of water. Dovetail uses reverse osmosis to try to replicate the water of Pilsen, the Bohemian city where the pilsner beer was born—the resulting liquid is noticeably different from what comes out of the average Chicago tap. The European-style touches don't end there; you'll also see a giant steel tub that is used to expose wild beers to natural bacteria in the air and a copper kettle that's more than 100 years old. When the tour is over, continue pretending that you're in Germany with a radler and a pretzel in Dovetail's taproom.
Booze included: Three .3L pours selected by the tour guide and a complimentary .3L Dovetail glass.
