A shipwreck discovered off the coast of southern France included nearly 10,000 amphoras containing nearly of Greek wine, presumably destined for trade up the Rhône and Saône rivers into Gaul.

The Greeks also employed vine training with stacked plants for easier cultivation and harvesting, rather than let the grapevines grow untrained in bushes or up trees. While ampelographers have been unable to identify the exact ancestry of any current "Vitis vinifera" grape variety among those grown by the ancient Greeks, several—e.g. Aglianico (also known as "Helleniko"), Grechetto, and Trebbiano (also known as "Greco")—have distinct Greek heritage. Not all Greek viticulture techniques were widely adopted by other wine regions. Some Greek vineyards used mysticism to ward off disease and bad weather.
