The short answer (TL;DR)

A Greek wine label normally tells you, in roughly this order: the producer’s name, the grape variety or wine name, the region or appellation, the vintage, the alcohol percentage, the bottle capacity, and — for serious wines — a PDO (“Protected Designation of Origin”) or PGI (“Protected Geographical Indication”) classification. Look for these seven elements and you will know, at a glance, whether the wine in front of you is a generic table wine or a serious appellation bottling.

The seven elements every Greek label carries

1. Producer (winery name). Usually the most prominent text on the label. Producers signal style: a Naoussa Xinomavro from one estate is not the same as another’s.

2. Grape variety or wine name. Either the variety (Assyrtiko, Agiorgitiko, Moschofilero) or the proprietary name of the wine (Megas Oenos, Ramnista, Thalassitis). Proprietary wines almost always list the variety on the back label.

3. Region or appellation. Santorini, Nemea, Naoussa, Mantinia, Patras, Cephalonia. The PDO or PGI status formally controls what may be written here.

4. Vintage. The year the grapes were harvested. For serious bottles this matters; for entry-level wines less so.

5. Alcohol percentage. Almost always between 12 % and 14.5 % for Greek dry wines. Vinsanto and other sweet wines climb higher.

6. Bottle capacity. Standard is 750 ml for still wines; 500 ml is common for Vinsanto.

7. Classification. PDO (ΠΟΠ), PGI (ΠΓΕ), or simply wine of Greece. Explained below.

What does “PDO” mean?

PDO stands for Protected Designation of Origin (in Greek: ΠΟΠ, Prostatevomeni Onomasia Proelefsis). It is the strictest European quality classification, and it means that:

  • the wine comes from a specifically defined geographic area,
  • the grape varieties allowed are tightly regulated,
  • yields, winemaking techniques and (where relevant) ageing requirements are controlled,
  • the entire process is overseen by the relevant Greek and EU authorities.

Examples of major Greek PDOs include PDO Santorini, PDO Nemea, PDO Naoussa, PDO Mantinia, PDO Cephalonia and PDO Patras.

A bottle labelled PDO Santorini (dry white) is made from at least 85 % Assyrtiko, with the balance from the permitted local varieties Aidani and Athiri, grown on Santorini and vinified to the appellation’s specifications. (Many PDO Santorini whites are in fact 100 % Assyrtiko.) The label is, in effect, a guarantee.

What does “PGI” mean?

PGI stands for Protected Geographical Indication (in Greek: ΠΓΕ, Prostatevomeni Geographiki Endeixi). The rules are looser than PDO — typically a larger geographic area and a wider range of permitted grape varieties — but the indication still ties the wine to a specific Greek region.

Examples include PGI Drama (Northern Greece, where international varieties like Sauvignon Blanc and Cabernet are widely grown alongside indigenous ones) and PGI Peloponnese.

PGI is not “lesser” than PDO — many extraordinary wines are made under it, particularly with international varieties that PDOs do not allow.

”Old Vines” / Palaies Klimates / Vieilles Vignes

There is no single European legal definition of “Old Vines,” but in Greek practice the term usually denotes vines of 40 years or older. Old vines tend to produce lower yields, more concentrated fruit and a stronger expression of site. On Santorini, where ungrafted vines often exceed a century, the term is essentially redundant — but on the mainland it tells you something meaningful.

Other special indications you may see

  • Single Vineyard. A wine made from a single named plot. A sign of intent: the producer is showcasing site rather than house style.
  • Estate Bottled (Κτήμα / Domaine). All grapes from the producer’s own vineyards within the appellation.
  • Wild Ferment. Fermented with indigenous yeasts from the vineyard, rather than commercial yeasts. Adds texture and savoury complexity.
  • Natural Wine. No single legal definition, but typically minimal intervention: indigenous yeasts, little or no added sulphur, no fining or filtration. Read producer notes for specifics.
  • Reserve / Reserva / Grande Reserva. For PDO Nemea and PDO Naoussa, these terms have specific minimum ageing requirements set by the appellation. Elsewhere they may indicate the producer’s own house category.
  • Nykteri. A traditional Santorini style: late-picked grapes, fermented overnight, aged in oak.

FAQ

What does “Reserve” actually mean on a Greek label? On PDO wines (notably Nemea and Naoussa), Reserve and Grande Reserve indicate longer minimum ageing periods set by the appellation. On non-PDO wines, the term is used at the producer’s discretion to indicate a step up from the standard cuvée.

Is the vintage on a Greek wine important? For entry-level wines, less so; they are made to drink within a few years. For premium wines — top Nemea, Naoussa, single-vineyard Santorini — vintage matters considerably and reflects both the season and the wine’s drinking window.

Where on the label is the alcohol percentage shown? Almost always on the front label, near the bottom, as a small number followed by ”% vol.” — typically between 12 % and 14.5 % for Greek still wines.
