Santorini Wineries: A Journey Through Volcanic Terroir and Ancient Traditions
Santorini, a jewel of the Cyclades in the Aegean Sea, is renowned for its breathtaking sunsets, whitewashed villages, and unique volcanic landscape. But beyond its iconic beauty lies a rich and deeply rooted winemaking tradition that has captivated people for millennia.
The island’s distinctive terroir, shaped by a cataclysmic volcanic eruption, has fostered a winemaking culture unlike any other, producing wines that are as singular and captivating as Santorini itself.

A History of Winemaking on Santorini
The story of winemaking on Santorini dates back an astonishing 3,500 to 4,000 years, making it one of the oldest wine-producing regions in the world. Archaeological evidence suggests that the Minoan civilization, which flourished before the island’s massive eruption around 1600 BC, cultivated vines and produced wine. While the eruption buried the island in a thick layer of volcanic ash, effectively wiping out all life, the resilient vines were eventually replanted, and winemaking resumed, a testament to the island’s enduring viticultural spirit.
During the Middle Ages, particularly under Venetian rule from the 13th to 16th centuries, Santorini’s wine trade truly flourished. Venetian merchants introduced the island’s wines to European markets, where they quickly gained a reputation for their intense acidity, minerality, and remarkable aging potential.
The sweet, sun-dried wine known as Vinsanto became a particularly prized export, even serving as the official Eucharistic wine for the Russian Orthodox Church for a period. This historical significance speaks volumes about the quality and longevity of Santorini wines.

One of the most remarkable aspects of Santorini’s wine history is its immunity to the phylloxera epidemic of the 19th century. Unlike most of Europe, where vineyards were decimated by this vine louse, Santorini’s unique sandy, volcanic soils acted as a natural barrier, preventing the parasite from surviving. As a result, many of the vines on Santorini are ungrafted and centuries old, contributing to the unparalleled depth and complexity found in the island’s wines today. This ancient lineage gives Santorini an almost mythical quality in the wine world.
Traditional viticultural practices, such as the unique “kouloura” vine-training system, have been preserved and perfected over generations. This method involves weaving the vines into low-lying, wreath-like baskets on the ground, protecting the grapes from the island’s strong winds, scorching sun, and minimal rainfall, while also capturing the nocturnal sea mist for essential moisture. This ingenious adaptation to the harsh environment is a cornerstone of Santorini’s winemaking heritage.
Today, Santorini’s winemakers skillfully blend these ancient traditions with modern technology, producing world-class wines that continue to gain international recognition. The island’s dedication to its indigenous grape varieties and unique terroir ensures that Santorini remains a vital and fascinating region for wine enthusiasts.

The Taste of Volcanic Earth: Typical Santorini Wines
Santorini’s wines are truly a reflection of their volcanic origin, offering a sensory experience unlike any other. The island’s unique soil, high temperatures, strong winds, and limited rainfall contribute to wines with distinctive characteristics.
Assyrtiko: This white grape variety is the undisputed queen of Santorini and accounts for the vast majority of the island’s vineyard plantings. Assyrtiko wines are celebrated for their bracingly high acidity, often described as “piercing” or “razor-sharp,” which gives them incredible freshness and longevity. They typically exhibit intense minerality, often evoking notes of wet stone, flint, and a distinctive salinity, a direct influence of the volcanic soil and sea air. Aromas lean towards citrus, particularly lemon and grapefruit, sometimes with hints of green apple or passionfruit.
While most Assyrtiko is fermented and aged in stainless steel to preserve its crispness and purity, some producers also create oaked versions, known as Nykteri. These barrel-aged Assyrtikos develop greater complexity, with notes of toasted nuts, honey, and a richer texture, while still retaining their signature acidity. Assyrtiko’s vibrant character makes it an ideal pairing for the island’s fresh seafood cuisine.
Nykteri: A Protected Designation of Origin (PDO) wine, Nykteri is a dry white wine made primarily from Assyrtiko grapes (at least 75%), often blended with smaller percentages of Athiri and Aidani. Traditionally, Nykteri grapes were harvested at night (hence “nykteri,” meaning “night” in Greek) to avoid the intense daytime heat.
These wines are typically aged in oak barrels for at least three months, resulting in a more full-bodied wine with a richer texture, heightened aromas of citrus peel and honey, and a longer, more complex finish.
Vinsanto: This naturally sweet dessert wine is arguably Santorini’s most famous and historically significant wine. Vinsanto (a name derived from “Vino di Santo” or “wine of Santorini”) is made from sun-dried grapes, primarily Assyrtiko, Athiri, and Aidani. After harvesting, the grapes are laid out in the sun for 7 to 15 days to dehydrate, concentrating their sugars and flavors.
The resulting must undergoes a slow fermentation, often lasting several months, and is then aged in oak barrels for a minimum of two years, though many Vinsantos are aged for significantly longer. The long aging process contributes to its characteristic amber color and complex aromas of dried fruits (apricot, fig, raisin), honey, caramel, coffee, and spices. Vinsanto offers a rich, velvety texture and a delightful balance of sweetness and acidity, making it a truly exceptional dessert wine, perfect for savoring on its own or with rich cheeses and desserts.
Athiri & Aidani: These are other indigenous white grape varieties found on Santorini. Athiri produces lighter, more aromatic white wines with floral and citrus notes, while Aidani contributes delicate floral aromas and a subtle sweetness. Both are often blended with Assyrtiko to add complexity and aromatic nuances to dry white wines.
Mavrotragano & Mandilaria: While Santorini is predominantly known for its white wines, there are also a few red varieties. Mavrotragano is a rare red grape gaining recognition for producing intensely colored, full-bodied wines with firm tannins and aromas of dark fruit, herbs, and spices. Mandilaria, another red grape, offers deep color and high tannins, often contributing to robust blends.

Uncorking the Experience: Booking Santorini Wine Tours
For any visitor to Santorini, a wine tour is an absolute must-do. It offers a unique opportunity to delve into the island’s liquid history, witness its distinctive viticultural practices at first hand, and, of course, taste the exceptional wines. Booking a wine tour in Santorini is straightforward, with a variety of options to suit different preferences and budgets.
Many tour operators specialize in wine experiences, offering both small-group and private tours. These typically include transportation to several wineries, guided tours of the vineyards and cellars, and multiple wine tastings, often paired with local cheeses, cured meats, and traditional Greek meze (appetizers). Some tours even incorporate a sunset viewing at a scenic caldera-edge winery, combining two of Santorini’s most iconic experiences.

You can book wine tours online through various tour aggregation websites or directly on the websites of individual wineries. It’s advisable to book in advance, especially during the peak tourist season (May to September), as popular tours and wineries can fill up quickly. Many tour companies offer flexible booking options, including “book now, pay later” policies and free cancellation up to a certain point.
When booking, consider the duration of the tour, the number of wineries visited, the types of wines offered for tasting, and whether food pairings are included. Private tours offer more flexibility in terms of itinerary and pace, while small-group tours provide a social atmosphere and are generally more cost-effective. Don’t hesitate to check reviews and compare options to find the perfect Santorini wine adventure for you.
