Hanaps, or drinking vessels for wine, are frequently mentioned in 14th-century inventories. Few have survived, however, as silver plate was often melted down to realize funds for the owner. Wine, customarily diluted throughout the Middle Ages, was poured to the top of the boss and then water was added to the flare of the bowl, roughly in the proportion of four to one.
