St. Paul’s Flat Earth Brewing is re-branding and will change its name to Saint Paul Brewing beginning April 3.

The brewery will continue to produce Flat Earth’s four flagship beers, just under the new label. In addition, the brewery will partner with local nonprofit Footprint Earth to create a beer brand they’re calling Arbeer (a play on the word arbor). A portion of the proceeds from that beer will support Footprint Earth’s mission “to help educate local communities to be better stewards of Earth,” according to a news release.

The first Arbeer will be “a red ale with a low IBU, excellent drinkability and an earthy finish,” according to the release.

Saint Paul Brewing owner John Warner said part of the idea of the re-branding is to remove the name “flat” from the beer brand.

“Flat beer doesn’t fly for me,” Warner said.

There are other changes going on at the brewery, which is located on St. Paul’s East Side in the former Hamm’s Brewery.

The taproom, which is currently on the first floor, will move to the second floor, which is in the process of being renovated. That will be complete in October of this year.

Eventually, the rest of the second floor will also be converted into a restaurant, and the third floor will become an event center. Those changes aren’t going to be complete until fall of 2021, though, Warner said. Eventually, the first floor will become production, offices and packaging space.

Arbeer will be introduced at a tapping event at the brewery (688 E. Minnehaha Ave., St. Paul) at 4 p.m. April 2. The beer will be available at local bars and restaurants the first week of April to celebrate Earth Month.
