About Grossen Bart Brewery

Grossen Bart Brewery is a brewery on Delaware Avenue in Longmont. Its website says the taproom keeps up to 15 beers on draft at a time. That is a lot of choice from a single brewery.

The styles run from hoppy IPAs to stouts, porters and sours. You will also find Belgian dubbels and crisp lagers. The website calls its Perfect Pilsner a standout, with a crisp and refreshing balance.

You can take the beer home too. The website says cans and bottles are filled in-house. That makes it easy to bring a few pours home.
