(UPI) -- In an effort to revive an ancient ritual, an Australian winemaker says he plans on harvesting some of his grapes during a full moon -- in the nude. Mike Hayes, of Queensland, has been studying 4,000-year-old wine-making techniques as part of a Churchill Fellowship, The (Brisbane) Sunday Mail reported Sunday. Hayes said the first record of nude harvesting and crushing of the fruit with bare feet for wine came from Georgia, the birthplace of wine-making.
