Just across the shimmering blue waters of the Santorini caldera awaits a quieter world, one that remains untouched, authentic, and deeply rooted in the volcanic soul of the Cyclades. This is Therassia, a small island where time appears to move differently. While the rest of the world flocks to the white-washed cliffs of Oia, a remarkable new wine story is unfolding at Mikra Thira, the first winery ever established on this secluded sister island.

For the modern traveller seeking experiences beyond the ordinary, Mikra Thira offers what has become modern luxury itself: an unhurried connection to the land. Born from volcanic soil and sculpted by the relentless Aegean winds, Therassia shares the legendary terroir that made Santorini’s wines world-famous. Yet, it possesses a unique microclimate and a rugged landscape that feels ancient and elemental. Here, ungrafted vines, many over 80 years old, thrive in the mineral-rich earth, cultivated using the traditional “kouloura” basket-pruning method found nowhere else on earth.

The vision for Mikra Thira began in 2007, eventually becoming a reality a decade later when acclaimed Greek winemakers Vangelis Gerovassiliou, Vassilis Tsaktsarlis, and Ioanna Vamvakouri united with a bold ambition: to bottle the raw beauty of Therassia. What they have created is far more than a mere production site. Nestled near the village of Potamos and overlooking an endless horizon of Aegean blue, Mikra Thira is a destination where architecture and landscape exist in perfect harmony. Designed in the classic Cycladic style using local materials, the winery houses state-of-the-art facilities alongside an intimate tasting space that offers, quite frankly, unforgettable sea views.

At the heart of the Mikra Thira philosophy is a profound respect for the island’s fragile ecosystem. The vineyards are cultivated organically, reflecting a commitment to sustainability and a slower, more intentional approach to luxury. The portfolio spans both islands, with the iconic Assyrtiko grape taking centre stage. Celebrated for its crisp acidity and saline minerality, every bottle captures the essence of this dramatic volcanic theatre.

But perhaps the greatest luxury Mikra Thira offers is the thrill of discovery. Far from the well-trodden tourist paths, Therassia invites you to slow down, breathe in the salt-heavy air, and experience the Cyclades as they once were: pure, elemental, and deeply inspiring.

Whether you are walking the volcanic earth, tasting wines born from ancient vines, or watching a gold-leaf sunset melt into the Aegean from Greece’s most unspoiled vantage point, Mikra Thira represents the next, most exclusive chapter of Santorini’s legendary wine heritage. It is, quite simply, the caldera’s best-kept secret.
