 The 4th-century BC Greek writer Theophrastus left a detailed record of some Greek influences and innovations in viticulture, one of which was the study of vineyard soils and their proper match to specific grapevines.Another innovation was the minimization of yields for more intense concentration of flavors and quality, rather than increased quantity.The economics of the time favored high yields for most crops, and intentionally limiting agricultural output was exceedingly uncommon in the ancient world.
