Wine Tasting in Santorini

Santorini is one of the world’s most celebrated wine destinations. Perched above a 3,600-year-old volcanic caldera, the island’s vineyards produce wines unlike anything else in Greece, built on one of the oldest winemaking traditions in the Aegean and a terroir that simply cannot be replicated.

Here is what to know about wine tasting in Santorini, from the grapes that define the island to the wineries worth visiting.

What Makes Santorini Wine Unique?

Santorini wine is unique because the island’s vines grow in volcanic soil without irrigation, producing small, intensely concentrated grapes that yield wines with high acidity, distinct minerality, and flavors impossible to replicate anywhere else. Santorini’s volcanic soil is one of the few places on earth where phylloxera cannot survive, meaning many of the island’s vines are ungrafted and several centuries old. To survive near-constant winds and low rainfall, local farmers train their vines into a distinctive low basket shape called a kouloura, which protects the grapes from the elements and concentrates their flavor.

Santorini's Signature Grape Varieties

Before you sit down for a wine tasting in Santorini, it helps to know the grape varieties you are likely to encounter.

Assyrtiko

Assyrtiko is Santorini's flagship grape and one of the most distinctive white wine varieties in the world. It produces dry whites with sharp citrus and green apple notes, bracing acidity, and a saline mineral finish that comes directly from the volcanic soil. Look for it in its pure form as a single-varietal Santorini PDO white, or blended with Athiri and Aidani for a slightly rounder, more aromatic style.

Nykteri

Nykteri is a rich, barrel-aged expression of Assyrtiko that takes its name from the Greek word for "night," a nod to the tradition of harvesting grapes after dark to preserve their acidity in the summer heat. It is fuller-bodied than a standard Assyrtiko, with notes of stone fruit, honey, and toasted oak, while retaining the grape's signature mineral edge.

Vinsanto

Vinsanto is Santorini's celebrated sweet wine, made from sun-dried Assyrtiko, Athiri, and Aidani grapes that are left to raisin on the vine before pressing. It is amber in color, intensely concentrated, and layered with dried fig, caramel, coffee, and spice. Aged in oak barrels for a minimum of two years, Vinsanto is one of the most complex dessert wines produced anywhere in the Mediterranean.

Mandilaria

Mandilaria is the island's primary red grape variety, producing wines with deep color, firm tannins, and flavors of dark cherry and earthy spice. It is often blended with Mavrotragano, a rarer indigenous variety, for more structured red wines.

The Best Wineries in Santorini to Visit

Santorini has a concentrated cluster of exceptional wineries, many perched along the caldera rim with panoramic Aegean views. These are the standout names worth knowing before your port day.

Santo Wines

Santo Wines is Santorini’s largest and most visited winery, operated by the island’s agricultural cooperative and representing over 1,200 local growers. Its tasting terrace sits high above the caldera near the village of Pyrgos, offering one of the most spectacular views on the island.

Estate Argyros

Estate Argyros is widely regarded as one of the finest producers in all of Greece, with vineyards that include some of the oldest ungrafted vines on the island, several estimated to be over 300 years old. Their benchmark Assyrtiko delivers bright citrus and stone fruit aromas with the island’s signature mineral finish.

Venetsanos Winery

Venetsanos Winery is one of Santorini’s most dramatically situated wineries, built into the cliffside above the caldera near Megalochori with unobstructed views of the Aegean below. The winery produces award-winning Assyrtiko-based whites and is the featured stop on the Unforgettable Wine Tour: Stunning Santorini Views, Tasting and Fira shore excursion.

Mikra Thira Winery (Thirassia)

For travelers looking to go beyond the main island, Mikra Thira Winery sits on the quieter neighboring island of Thirassia and focuses on indigenous varieties including Assyrtiko and Mandilaria grown in volcanic soil. It is the featured winery on the Thirassia Winery Tasting and Blue-Domed Santorini shore excursion.

Estate Karamolegos

Estate Karamolegos is one of the island’s most recognized producers, known for a wide portfolio spanning Assyrtiko whites, sweet Vinsanto, and rich reds with deep fruit and warm spice notes.

Wine Tasting at Royal Beach Club Santorini

Royal Beach Club Santorini is Europe’s first-ever Royal Beach Club, located along a volcanic black sand beach with spectacular views of the Aegean Sea. For cruisers looking to combine a premium beach day with an authentic local wine tasting, the Ultimate Santorini Day with Royal Beach Club + Wine Tasting excursion is the most complete way to experience both.

Wine Tasting in Santorini: Tips for Cruise Travelers

• Book early. Royal Signature Excursions like the Thirassia Winery Tasting and the Venetsanos Wine Tour have limited availability, so booking before your sailing is the move.
• Start with Assyrtiko. It is the lens through which every other Santorini wine makes more sense, and it pairs well with virtually everything on a Greek mezze spread.
• Do not skip Vinsanto. Even if you do not typically drink sweet wine, Santorini’s Vinsanto surprises most first-time tasters with its complexity. Sun-dried grapes and decades of oak aging produce something genuinely unlike any other dessert wine in the Mediterranean.
