Thread Name: Whiskey in the Jar
Subject: RE: Whiskey in the Jar
In Britain, a "jar" is a wide-mouthed bottle, suitable for putting jam and pickles in. Storage jars - such as the "Kilner" jar - are adapted for long term storage and were the (recyclable) forerunners of tin cans.

Jars have, historically, been used for storing liquids as well and, presumably, drinking from them was common as can be deduced from common usages such as "I'll have a jar" (= a drink (usually) of beer) replacing "I'll have a pint".
