GOP lawmaker slams Teamsters for meme about 'free the growler' bill The bill would remove the cap that prohibits five breweries from selling growlers and beer to go. Author: One of the sponsors of a bill to "free the growler" got into a chippy exchange on Twitter with the Teamsters Union that opposes the proposal. State Rep. Jim Nash, R-Waconia, along with a bipartisan group of Minnesota legislators last week announced a bill that would allow all breweries in Minnesota to sell growlers by removing the "growler cap" in state law. The "growler cap" prohibits breweries that sell more than 20,000 barrels per year from selling growlers and beer to go. Currently, there are five breweries that are too big to sell growlers.
