Some beers are drunk for their taste. Some beers are drunk for their alcohol content. Others are for volume drinking. Sometimes you want a cheap, not too alcoholic drink that you can sit and get steadily drunk with, without getting twatted after a few pints. In the UK drinks such as Carling and Strongbow do this job. Not the classiest or the tastiest drinks, but you can get into double figures without making a tit out of yourself.
"Fancy a Stella?"
"No, mate, I'm on the Carling. Strictly volume drinking tonight"
