Ancient Rome was in a nebulous state throughout its existence. From roughly 800 B.C. all the way up to the Roman Empire’s collapse in 476 A.D., the area that qualified as Rome stretched from parts of Africa through most of Europe and even the Middle East. Viticulture was bubbling up through Greece and Italy, eventually making its way to the rest of the far-off Roman territories. And, much like the empire’s landscape and politics, its drinking habits were volatile and constantly changing.
