Santorini

Quick answer

Santorini is a Greek wine region in the southern Aegean Sea and the Cyclades island group. In Greek and European Union wine law, Santorini is a Protected Designation of Origin (PDO): a protected place name with rules about where the grapes come from and how particular wines are made.

The legal PDO area covers the islands of Santorini and Thirasia. That matters because a bottle labelled Santorini refers to a defined place, not to every Greek wine made from Assyrtiko.

The region’s most important grape is Assyrtiko, a white variety that originated on Santorini and is now grown in other parts of Greece. Dry Santorini PDO white must contain at least 85% Assyrtiko under the current specification. These wines are typically dry, firmly acidic, concentrated and textural, often with citrus and savoury or steely impressions. Individual wines can vary with vineyard site, yield, harvest timing, vintage and winemaking.

Santorini is also associated with Vinsanto, a traditional sweet wine made from raisined grapes. Vinsanto is a specific regional style and designation, not a synonym for all sweet wine.

Where is Santorini?

Santorini lies in the southern Aegean Sea, southeast of mainland Greece, and is the southernmost of the Cyclades islands. Fira is the island’s main administrative and orientation centre. Familiar localities include Pyrgos, Megalochori, Akrotiri, Emporio, Mesa Gonia, Exo Gonia, Vothonas, Vourvoulos and Oia.

These town names help you understand the island’s geography, but they should not be mistaken for separate wine regions. The protected wine name is Santorini, and the demarcated PDO area also includes Thirasia.

There is no useful mainland driving time from Athens: Santorini is an island reached by air or sea. For an Australian learner, the practical point is simply that Santorini is a specific Greek island origin, within the wider geographic context of Greece, the Aegean and the Cyclades.

Greek PDO terminology is not identical to the Australian GI system. Both protect geographic names, but a Greek label should be read according to its Greek and EU designation rules rather than Australian regional categories.

What is Santorini wine known for?

Santorini is best known for dry white wine based principally on Assyrtiko. The grape contributes naturally firm acidity, while the island’s growing conditions can produce wines with substantial body, concentration and a noticeable palate texture.

“High acidity” does not mean the wine is thin or flavourless. A Santorini white can be both refreshing and weighty: think citrus-like freshness alongside a broad, dense or almost salty-feeling texture. These are broad expectations, not guarantees for every bottle.

The official description includes citrus and lemon- or orange-peel characters, steely notes, freshness and a rich palate. You may also see the word minerality used for some wines. Treat that as a sensory description, not as proof that volcanic rock has transferred a literal flavour to the wine.

The same grape can taste different outside Santorini. An Assyrtiko from another Greek region may be a very good wine, but the word Assyrtiko alone does not guarantee the classic Santorini combination of structure, acidity and texture.

Why are the vines trained in baskets?

Santorini is dry, exposed and windy. Strong seasonal northerly winds, including the Meltemi, influence how vines are grown. Instead of being trained on a conventional upright trellis, many vines use kouloura: their canes are shaped into a low, circular basket close to the ground.

The basket helps shield the fruit from strong winds and intense exposure. It is a practical response to the island’s conditions, not merely a decorative tradition. Other traditional training systems also exist, and not every vineyard uses exactly the same form.

Santorini’s soils are volcanic-derived and include pumice and ash. Rainfall is very low, creating limited water availability and water stress. Sea air and dew are also part of the island’s growing environment. Together, these factors help explain vineyard choices and recurring structural tendencies, but they do not mechanically determine flavour. Site, vine age, crop level, weather and winemaking still matter.

What is Vinsanto?

Vinsanto is associated with Santorini’s sweet wines made from raisined grapes. Grapes are dried before fermentation, concentrating their sugars and flavours. The relevant PDO rules distinguish between wine from raisined grapes and liqueur wine from raisined grapes, with specific production and ageing requirements.

That is why Vinsanto should not be used as a loose synonym for “sweet wine”. Nor should it be confused with Italy’s Vin Santo, which refers to different Italian wine traditions.

For an Australian reader, the label distinction is useful:

• Santorini tells you the protected place of origin.
• Assyrtiko tells you the principal grape variety.
• Vinsanto identifies a specific traditional sweet, raisined-grape style.

How to read a Santorini label

If you see “Santorini” or “Santorini PDO”, you are looking at a wine connected to the defined Greek origin. If you see “Assyrtiko” without Santorini, check the stated origin: the wine may come from another Greek region.

A dry Santorini white is a useful choice when you want freshness without a lightweight palate. Serve it chilled, but not so cold that its texture and aroma disappear. Its acidity and structure can work well with grilled prawns, oysters, baked fish, feta, lemon, herbs and other salty or high-acid foods.

The simplest way to remember the region is: Santorini is the place, Assyrtiko is the grape, and Vinsanto is the traditional sweet style.

Frequently asked questions

Is Santorini a grape variety?

No. Santorini is a place and a protected wine designation. Assyrtiko is the grape most strongly associated with the region.

Is all Assyrtiko from Santorini?

No. Assyrtiko originated on Santorini but is now planted in other Greek regions.

Is Santorini wine always white?

The region is principally known for dry white wine, especially Assyrtiko-based wine. The PDO also covers specific raisined-grape and liqueur-wine categories. Do not assume every wine associated with the island has the same style.

Is Vinsanto the same as sweet wine?

No. Vinsanto is a specific traditional Santorini style made from raisined grapes. It is not a generic term for all sweet wine.
