PURL

Purl is a hot beer flavoured with gin, sugar and ginger. It was originally beer or ale mixed with gin, wormwood, or other bitter herbs, but the recipe changed towards the end of the 19th century. It was popular in England around the end of the 19th century and the start of the 20th century, and would often be sold on the canals and waterways by travelling salesmen known as
purlmen.
