Well, duh. The Greeks spread wine production all over the ancient Mediterranean.
It’s funny that they don’t have a popular international wine product today. I never see Greek wines promoted here, and we’re mildly cosmopolitan: our health-foods store had a special on Georgian wines a while back ... the former Soviet republic, not the state a few hours south.
They don’t make enough to ship ‘em anywhere. :’) If you look in the better stores (specialty shops, gourmet cooking joints, high-end liquor stores, and Greek groceries) you’ll find some selection, including Retsina, which has been called the national beverage of Greece. It’s wine mingled with pine resin, and it has been identified in Mycenaean kitchen artifacts (IOW, older than this 600 BC thing).
Most larger wine shops carry at least a bottle or two of Nemea. Goes very well with rack of lamb.
