Growler (jug)

A growler (US) (/ˈɡraʊlər/) is a glass, ceramic, or stainless steel bottle (or jug) used to transport draft beer.

The significant growth of craft breweries and the growing popularity of home brewing has also led to an emerging market for the sale of collectible growlers.

A properly sealed growler will hold carbonation indefinitely and store beer like any other sanitized bottle.

Some growler caps are equipped with valves to allow replacement of carbon dioxide lost while racking.

The term likely dates from the late 19th century when fresh beer was carried from the local pub to one's home by means of a small galvanized pail.
