Meditrinalia was a Roman feast of unclear meaning, probably dictated by a wish to honour the new grape harvest. At that time, people devoted themselves to the consumption of wine from the new vintages, which wanted to gain the favour of the gods. It is known that this festival was associated with Jupiter and played an important role in the agricultural rituals of early Rome.
Little information about this holiday has been preserved. The festival was probably of great importance in an early Roman agricultural society.
