Salt I have about a dozen brown glass growlers in the shed from Magic Hat and Cape Cod Beer. I usually use two for each visit to the Cape Cod Beer brewery, but I havent gone since the dead of winter. My brother just stashes the magic hat ones for when he goes to vermont about once a year. deffinately the way to go. but like mentioned, you pretty much need to drink the growler that day or else it goes flat; having said that, its not usually a problem cuz its always something delicious
