Mead, a honey-based fermented beverage, was used as early as the 5th century and was widely used by the Middle Ages. Monks originally created the drink as a medicine, but its happy effect caused it to became popular with everyone.
The term "honeymoon" came from the use of mead after a wedding. After the final toast, the bride and groom were supplied with enough mead for a month (one moon). This was believed to enhance fertility, especially for a son.
