Two wine festivals were celebrated each year by the ancient Romans. One, in April, according to the William Smith Dictionary, on Lacus Curtius, was the urban wine festival, Vinalia urbana (as opposed to the August country wine festival, Vinalia rustica), at which occasion wine casks were first opened and tasted, with a libation poured to Jupiter.
Happy Wine Tasting!
