Growler

A growler is a refillable container for fresh draught beer, often made of glass or stainless steel with a sealable lid. Common sizes are roughly one to two litres. Breweries and shops fill it at the tap.

Unlike beer in gas-tight bottles or cans, the beer keeps only for a limited time because carbonation and freshness fade quickly once opened. In Germany, food law requirements apply to filling and handing over.
