From the announcement in April:
I was surprised at this as well. Consolidation would make sense, but it may be they don't have the capital to grow and consolidate all in one move.The timeline remains tentative, Hauschild said, but "let's just say we’re hopeful we’re brewing beer at the new location in 2014.”
The new brewery is meant to expand on, rather than replace, the Brooklyn Center location, which will remain operating for the foreseeable future.
They may have to stop using it as a tap room, but I'm guessing they will leave it intact to use for other events. Their current tour set up in Brooklyn Center starts in what is basically already a 'tap room' but this update will likely improve on the plastic chairs and tables they currently have next to the bar.According to the article, they can only have 1 taproom open, so as soon as the new Brewery in Minneapolis is open, they have to shut down the Brooklyn Center taproom by law.
