Germany, or rather the area that belongs to it today, has a wine culture that is over two thousand years old. But imported wine was already being drunk before that, as evidenced by a Greek wine bottle made of clay dating from around 400 BC found in a Celtic tomb. The oldest vineyards were located on the banks of the Rhine, Neckar and Moselle. These rivers with their elongated valleys, as well as their tributaries, are still the classic growing areas today. Viticulture was established by the colonization of the Greeks in Gaul and then brought to perfection by the Roman culture. The conquest of Gaul by Julius Caesar (100-44 BC) brought Roman viticulture from the Rhône valley to the Rhine.
