Greece
A study guide to Greece through three grapes — volcanic Assyrtiko from Santorini, silky Agiorgitiko from Nemea, and tannic, age-worthy Xinomavro from Naoussa.
Greece has been making wine for around four thousand years, and its greatest strength is one almost no other country can match: a deep bench of indigenous grape varieties grown nowhere else, on volcanic islands and cool northern mountains alike. You could spend a career on them, but three do most of the work of putting Greece on the world's fine-wine map — and if you learn these three, you understand modern Greek wine.
The trick is to treat Greece as three grapes in three terroirs: Assyrtiko, the searing white of the volcanic island of Santorini; Agiorgitiko, the supple red of high-altitude Nemea in the Peloponnese; and Xinomavro, the fierce, age-worthy red of cool, northern Naoussa. Fix those three and the rest of Greece falls into place around them.
The one thing to fix first: three grapes, three terroirs
Greece is hot and Mediterranean, but its best wines all come from somewhere that tempers the heat — an island wind, a mountain plateau, a northern slope.
- Assyrtiko — Santorini (white). Bone-dry, saline, and screamingly high in acidity, off ancient phylloxera-free, volcanic vineyards.
- Agiorgitiko — Nemea (red). Deeply coloured, soft and velvety; altitude is the dial that turns it from plush and fruity to structured and age-worthy.
- Xinomavro — Naoussa (red). Pale but ferociously tannic and acidic, and built to age for decades — Greece's answer to Nebbiolo.
Assyrtiko — Santorini PDO
If Greece has one truly world-famous wine, it is Santorini. The island is a drowned volcano in the southern Aegean, and its vineyards are unlike anywhere else on earth: planted on deep volcanic ash, pumice and sand with almost no clay, and — because phylloxera cannot survive in that sandy soil — ungrafted, own-rooted, and phylloxera-free, with some vines centuries old.
Santorini, in the Cyclades (southern Aegean): the wine villages ring the flooded volcanic caldera. Labels-only, on a 3D terrain basemap — tilt and rotate to see the caldera cliffs; there is no boundary overlay.
The other half of the story is wind. Santorini is fiercely dry and swept by the summer meltemi, so growers weave the vine canes into a low, ground-hugging basket called a kouloura — the grapes grow inside the coil, sheltered from wind and sun and able to catch the night's sea dew, the vineyard's main source of moisture.
The grape is Assyrtiko, and it is a marvel: it holds blistering acidity even at full ripeness under a blazing sun. PDO Santorini dry white is at least 75% Assyrtiko (often 100%, sometimes rounded out with local Athiri and Aidani), giving a wine that is bone-dry, high in alcohol, and unmistakably saline — lemon and lime, crushed seashell, and a smoky, flinty mineral bite — that ages beautifully. Two variations are worth knowing: Nykteri (a riper, barrel-aged Santorini) and Vinsanto (a lusciously sweet wine from sun-dried Assyrtiko).
The three grapes at a glance

|---|---|---|---|---|
| Assyrtiko | Santorini | Cyclades (S. Aegean) | White | Bone-dry, saline, searing acid, mineral; ages |
| Agiorgitiko | Nemea | NE Peloponnese | Red | Deep colour, soft velvety tannin; plush → structured with altitude |
| Xinomavro | Naoussa | Macedonia (north) | Red | Pale, high acid + high tannin, tomato/olive; ages decades |

Greek wine law, in brief
Greece follows the EU model. PDO (Protected Designation of Origin; in Greek ΠΟΠ) is the top tier — grapes 100% from the named zone, with set varieties, yield limits, and tasting approval; Santorini, Nemea and Naoussa are all PDOs. Below it, PGI (Protected Geographical Indication; ΠΓΕ, also called regional wine / Topikos Oinos) needs at least 85% from its larger zone and allows more grapes (including international ones). Plain Wine (table wine) is the base. As a rule, the tighter the geography on the label, the stricter the rules behind it.

The full guide below covers Greece's two great reds in depth:
- Agiorgitiko / Nemea — how altitude splits one grape into several styles
- Xinomavro / Naoussa — cool northern slopes and a red built to age
- The other homes of Xinomavro, food pairing, and classic exam questions
Agiorgitiko — Nemea PDO
Nemea, in the north-east Peloponnese, is Greece's largest red-wine PDO, and its wine is 100% Agiorgitiko ("St George's grape"). Agiorgitiko is the crowd-pleaser of Greek reds: deeply coloured, with soft, velvety tannins, ripe red and black fruit (plum, cherry), a lick of spice, and only moderate acidity — which is exactly why altitude matters so much here.
Nemea, in Corinthia (north-east Peloponnese, inland from the Gulf of Corinth): vineyards climb from the warm valley floor up to the high Asprokampos plateau. Labels-only 3D terrain — tilt to read the altitude; no boundary overlay.
The PDO is effectively an altitude ladder, and reading it is the key to the region:
- Valley floor (~230–450 m) — warmest; the earliest-ripening, softest, fruitiest, most immediately drinkable wines (and good rosé). Low acidity can make wines here flabby in hot years.
- Mid-slopes (~450–650 m) — the balanced middle ground, where most of the serious wine is grown.
- Asprokampos plateau (~650–1,050 m) — coolest and highest; harvest comes weeks later, acids stay fresh, and the wines are the most structured, aromatic and age-worthy (the best age 10–15 years).
Agiorgitiko is also wonderfully versatile — it makes everything from pale dry rosé to oak-aged, cellar-worthy reds — but the single most useful thing to know is that in Nemea, higher means fresher and finer.
Xinomavro — Naoussa PDO
If Agiorgitiko is Greece's charmer, Xinomavro is its aristocrat — a difficult, thrilling grape whose name literally means "acid-black". Naoussa, in Macedonia in the north, is its benchmark: PDO Naoussa is a dry red, 100% Xinomavro, aged a minimum of one year in oak (add even 1% of any other grape and it is legally demoted to Imathia PGI).
Naoussa sits on the eastern slopes of Mount Vermio in Central Macedonia, west of Thessaloniki and the Thermaic Gulf. Labels-only 3D terrain — tilt to see Vermio; no boundary overlay.
The vineyards climb the eastern slopes of Mount Vermio (roughly 150–400 m) in a cool, continental climate — cold winters, warm-but-not-scorching summers, and the mountain funnelling in cool, damp Aegean air. Xinomavro ripens late and needs every bit of that season.
The result is a wine often compared to Barolo's Nebbiolo: pale, almost translucent in colour, but with searing acidity and firm, drying tannins, and a haunting savoury aroma — red fruit, tomato and sun-dried tomato, black olive, dried herbs — that deepens with age into tar, leather and spice. It is austere and demanding young and can age for 10–20 years; it is Greece's most serious, longest-lived red.
Xinomavro turns up elsewhere in the north, too: higher, cooler Amyndeo (also rosé and sparkling), Goumenissa (blended with Negoska), and Rapsani on the slopes of Mount Olympus — but Naoussa is the grape's spiritual home.
Food
Greece's wines are table wines in the truest sense. Santorini Assyrtiko, all salt and acid, is made for the Aegean's grilled fish, octopus, and briny meze (and cuts through fried calamari like a knife). Agiorgitiko, soft and generous, is the friendly all-rounder — lamb, tomato-based stews (stifado), grilled meats. Xinomavro's acid and tannin want fat and umami: slow-cooked lamb and beef, aged cheese, mushrooms, and anything rich and savoury.
Classic exam questions
- Why are Santorini's vines phylloxera-free and ungrafted? — the deep, sandy volcanic soil the louse cannot survive in; the vines grow on their own roots.
- What is the kouloura, and why is it used? — a low, basket-shaped vine training that shelters the grapes from Santorini's fierce wind and sun and catches dew.
- What grape is PDO Nemea, and how does altitude change it? — 100% Agiorgitiko; low/warm sites give soft, fruity wine, the high Asprokampos plateau gives fresher, more structured, age-worthy wine.
- Describe PDO Naoussa and its grape. — dry red, 100% Xinomavro, min 1 year in oak; pale, high-acid, high-tannin, savoury (tomato/olive), long-lived.
- Which Greek grape is often likened to Nebbiolo, and why? — Xinomavro — pale colour but fierce acidity and tannin, and great age-worthiness.
- What do PDO and PGI mean in Greece? — PDO (ΠΟΠ): top tier, 100% from zone; PGI (ΠΓΕ / regional wine): ≥85% from a larger zone, more grapes allowed.
Three grapes, three terroirs — a volcanic island, a mountain plateau, a northern slope — and Greece stops being a wall of unfamiliar names and becomes three clear ideas you can taste.
