Ancient Greece and wine help satisfy demand. Wine historians have theorized that the Greeks may have introduced viticulture to Spain and Portugal, but competing theories suggest that the Phoenicians probably reached those areas first. The grape clusters, vines and wine cups that adorn Greek coins from classical times bear witness to the importance of wine to the ancient Greek economy. With every major trading partner, from the Crimea, Egypt, Scythia, Etruria and beyond, the Greeks traded their knowledge of viticulture and winemaking, as well the fruits of their own production.

Name of Greece "Graecia" (Greek: ), literally meaning 'the land of the Greeks', which was used by Ancient Romans to denote the area of modern-day Greece. Similarly, the Latin name of the nation was "Graeci", which is the origin of the English name "Greeks". Those names, in turn, trace their origin from "Graecus", the Latin adaptation of the Greek name Γραικός (pl. ), which means 'Greek', but its etymology remains uncertain. It is unclear why the Romans called the country "Graecia" and its people "Graeci", but the Greeks called their land "Hellas" and themselves "Hellenes". Several speculations have been made.
