An engraving shows Galla Placidia (390-450), daughter of Roman emperor Theodosius I, in captivity. New research shows in some cases, we are drinking almost the exact same wine as Roman emperors — our Pinot Noir and Syrah grapes are "siblings" of the ancient Roman varieties.

genetically similar to wines that may have existed for thousands of
years, a new study finds. In the face of climate change, that’s
risky.
