Many of today varieties bear probably inheritance shares of old vines in it, which already in the antique one of Greeks, Romans and Phoenicians were cultivated. However, most of today still existing traditional grape varieties may have emerged only in the Middle Ages or later centuries from the then existing varieties. Most of the ancient grape varieties had a blue or black berry color. The red, yellow and green varieties are only later through mutation originated and were through vegetative propagation obtained as independent color variants. So are Pinot Blanc. Pinot Gris and Pinot Meunier by buds mutations on Pinot emerged. Which varieties were actually cultivated by the Romans can only be surmised today, because of the Roman varieties there is nothing but Latin names and rough descriptions.
