To spot the Union Brewery, look for a large corner building with red brick walls, rows of tall windows, and a silver cupola on top, nestled behind some leafy trees right at the edge of the sidewalk.
Alright, time to raise a glass-at least in spirit! The Union Brewery, built in 1856 by two determined German immigrants, Anton Geiger and Simeon Hotz, is more than just pretty brickwork. Imagine Iowa City in the late 1800s: horse-drawn wagons rattling past, hints of malt and hops drifting from open cellar doors, and Conrad Graf, the legendary brewmaster, busy perfecting Graf’s Golden Brew in the cool beer caves below. When Iowa’s prohibition law hit in 1884, the Union Brewery was at the very center of a riotous rebellion-furious beer lovers stormed the streets, and poor Conrad ended up owing $7,000 after an angry attorney took him to court. Undaunted, the brewery pressed on, switching to soda during prohibition, but those clever yeast spores refused to retire; let’s just say their soda packed a little extra punch! Underneath your feet, a genuine secret: preserved tunnels snake from here to other old breweries, built to shuttle barrels between chilly beer caves. Over a century later, developers are still dreaming of reopening them for bold explorers. Since 1986, the Union Brewery’s been on the National Register of Historic Places-a toast to wild nights, underground mysteries, and very stubborn yeast!
