A diverting drinking vessel which could be found in village inns and public houses for centuries had a resurgence in popularity in the late eighteenth and early nineteenth centuries. These vessels had been made throughout England and northern Europe since at least the fifteenth century. Most commonly called puzzle jugs, they were also sometimes called teasing pitchers or wager jugs. It was a challenge to determine how to drink the liquor which they contained and wagers were often placed on the outcome of the attempt.
By the time of the Regency, puzzle jugs were being made not only for use in inns and taverns, but also for home use. Many gentlemen enjoyed entertaining their male visitors with drinking games using their own puzzle jugs.
