Beyond the Bailey
“A bentley is the non-alcoholic equivalent to rum punch. It is reputedly named after David Williams Bentley, Bishop of Barbados from 1927 to 1945, who is said to have invented it to encourage moderation among his flock. Fresh lime juice and sugar are also used to make lemonade (still) and lime squash (fizzy)”
