Greek wines from Assyrtiko, Xinomavro and the islands inward

Wine regions of Greece

Greece has 33 officially demarcated wine regions, spread across the mainland, the Peloponnese, and dozens of islands. The conditions vary sharply: Naoussa in northern Macedonia sits at 350 metres above sea level and produces structured reds from Xinomavro, a grape that shares Nebbiolo's acidity and tannic backbone but is grown almost nowhere outside Greece. The Aegean Islands — Santorini chief among them — produce Assyrtiko on volcanic soils with almost no rainfall during the growing season, which forces the vine to reach deep for moisture and concentrates the grape's naturally high acidity. Crete, the largest wine-producing island, has its own indigenous varieties: Vidiano in white and Kotsifali in red are both underrepresented in export markets. The Peloponnese region of Nemea is the primary source of Agiorgitiko, a grape capable of producing everything from light, early-drinking reds to age-worthy bottles with 15 or more years in the cellar. Patras, also in the Peloponnese, produces Muscat of Patras — a fortified sweet wine with PGI status that has been made in the region since the medieval period. Greek wine labelling follows EU rules, meaning PDO (Protected Designation of Origin) and PGI (Protected Geographical Indication) appear on labels alongside regional names that rarely appear on European supermarket shelves.

Signature grapes of Greece

Greece has over 300 documented indigenous grape varieties, of which fewer than 30 are in commercial production at any meaningful scale. Assyrtiko is the most internationally recognised: it originates on Santorini, where vines trained in a low basket shape called kouloura protect grapes from Aegean winds. Old Assyrtiko vines on the island are often pre-phylloxera, meaning they were never grafted onto American rootstock after the 19th-century epidemic that destroyed most of Europe's vineyards. Xinomavro — the name translates literally as 'acid black' — is the dominant red grape of northern Greece and the sole permitted variety in Naoussa PDO wines. It is high in both tannin and acid, ages well, and is occasionally compared to Barolo in structure, though the two grapes are genetically unrelated. Malagousia is a white grape that was nearly extinct in the 1970s before being rescued by a single producer in Epirus. It is now cultivated across several regions and produces aromatic whites with stone fruit and floral character. Moschofilero, grown primarily on the high-altitude Mantinia plateau in the Peloponnese at around 650 metres, produces pale-coloured, low-alcohol whites with pronounced aromatics. Roditis is a pink-skinned grape used widely across the mainland for light, dry whites. For those interested in how indigenous grapes perform in other European contexts, orange wines, white wines, and red wines from producers across the continent offer useful comparison points.

Climate and terroir in Greece

Greece is not climatically uniform. The country spans roughly 800 kilometres from north to south, with Mediterranean, semi-arid, and highland continental conditions all present within its borders. Average summer temperatures in the Cyclades exceed 30°C, while Naoussa in northern Macedonia regularly sees snow in winter and has cool nights during the growing season that preserve grape acidity. Santorini receives less than 250mm of annual rainfall — less than most desert definitions — meaning vines subsist almost entirely on moisture drawn from morning fog and volcanic subsoil. The island's pumice and volcanic ash soils drain rapidly and contribute to the mineral character associated with Santorini Assyrtiko. In contrast, Drama in northeastern Greece has a more continental climate with higher rainfall and cooler temperatures, and it has emerged as a region capable of producing international varieties — Cabernet Sauvignon, Merlot, and Syrah — with structure that compares to northern European benchmarks. Greek producers have increasingly moved toward altitude viticulture as average temperatures rise: vineyards above 600 metres now account for a growing share of premium production. The combination of Greek indigenous varieties with genuinely diverse terroir conditions means the country produces a wider stylistic range than its modest global export share suggests. Bottles ship directly from the producer's cellar — not from a warehouse in the Netherlands.
