In its infancy, wine was produced in regions where the vine grew wild. From its origins in the Near East, cultivation of the grapevine spread to the Old Kingdom of Egypt, and, around 2500 BCE, the vine was brought, via trade, to the Minoan Bronze Age civilization of Crete.
Despite Crete’s latitude, the island’s moderate climate proved suitable for the vine, and in viticulture the Minoans surpassed all their contemporaries. (They also developed indoor plumbing—clearly a civilization ahead of the times.) The practice was passed to their successors, the Mycenaeans, to other islands in the Aegean, and to the mainland of Greece. The Greeks spread cultivation of the vine throughout much of Europe. The first vineyards in France were in Massalia, a Greek colony at modern-day Marseilles, and Southern Italy’s modern varieties Greco and Aglianico may be Greek in origin. The Greeks took viticulture northward as well, to the banks of the Danube and the coastline of the Black Sea. Ultimately, the Greeks were responsible for not only spreading the vine geographically but also democratizing the consumption of wine. In ancient Egypt, wine was regarded as the sweat of the sun god Ra; the Greeks drank wine at religious and ceremonial events, but they also drank socially. As wine consumption in Greece spread to new social classes, additional vineyards were needed. The Romans carried the Greeks’ vines even farther, but the tradition of many modern-day European wine regions extends back to ancient Greece.
While preeminent in the ancient world, Greek wines languished until a late 20th-century surge in interest and quality. Greece’s vinous reputation had long been rooted in retsina, an aromatized wine flavored with Aleppo pine resin, and, for many, the wine is still the only reference point for the country
Per 5th Ed. Oxford Companion, the most planted white varieties in Bulgaria are apparently now Muscat Ottonel, Chardonnay, SB, and Red Misket (in that order).
