The Penn Museum published an article about the discovery of a type of alcoholic beverage that dates back to the early Neolithic period (7000–6600 BC). Recovered from early pottery from Jiahu, a village in the Yellow River Valley, remarkably preserved as liquids inside sealed vessels of the Shang and Western Zhou Dynasties.
The contents of the vessel was a mixed fermented beverage of rice, honey, and fruit well over 9,000 years old. While we would not recommend people drink the contents of the jar, the beverage was recreated by Dogfish Head Brewery and served at the Waldorf-Astoria Hotel, New York City, 19 May 2005.
