Waldmann Brewery and Wurstery (445 Smith Ave., St. Paul; 651-222-1857; waldmannbrewery.com), in one of the oldest commercial buildings in the Twin Cities, is officially up and running.

The Smith Avenue building is one of the oldest surviving commercial buildings in the Twin Cities. Built in 1857, it sat empty for years before Tom Schroeder bought it and began to research its history.

After discovering it was once a saloon, its fate was sealed, and Schroeder made the decision to turn it into a brewery. Waldmann is serving a tightly edited menu of sausages, including tasty housemade wursts and a snappy Red Table Meats hot dog, cheese and meat plates and other snacks that go well with drinking.

The opening beer menu includes a harvest hefeweizen, an oktoberfest, a pilsner and a festbier.

The building has been lovingly restored to close to its original state. Furniture, including oil lamps, either are or feel like they’re from the saloon’s heyday.

The brewery is open at 11 a.m. Tuesday through Sunday.
