Originating in the US, Canada and Australia, Growlers are 64 U.S. fl oz (3.2 pints) glass or ceramic jugs used to transport draft beer. The modern glass growler was first introduced by Charlie and Ernie Otto of Otto Brothers’ Brewing Company in Wilson, Wyoming in 1989.
The term dates back to the late 1800s when fresh beer was carried from the local pub to one’s home by means of a small galvanized pail. It is claimed the sound that the CO2 made when it escaped from the lid as the beer sloshed around sounded like a growl.
A properly sealed growler will hold carbonation indefinitely and store beer like any other sanitized bottle.
