Scientists have discovered and dated the oldest complete wine production facility ever found, including grape seeds, withered grape vines, remains of pressed grapes, a rudimentary wine press, a clay vat apparently used for fermentation, wine-soaked potsherds and even cups. Dating 1,000 years before the earliest comparable find, the 4100 B.C. discovery was made in the same mysterious Armenian cave complex as an ancient leather shoe announced last summer.
