The Vineyards

Exceptional Cycladic Aromas

Vines grown in the volcanic, porous soil of Milos under warm and dry climate conditions. Wine stored in an underground labyrinth which provides the needed humidity and steady, cool temperature. The whitewashed Kostantakis “Spilia” (Cave) opens its wooden doors and welcomes you to try its new production of uniquely flavored wines.


Kostantakis –Milos Cave Winery is located in Milos island, just 500 meters from the charming seaside village Pollonia and 300 meters from the closest seacoast. Konstantakis Winery is in the heart of a cultivated area of 4 hectares. At the same area are the majority of the vineyards of Kostantakis estate. Slightly elevated in the middle of a wonderful garden, next to Kostantakis Residence, the visitor can enjoy the unique and unlimited view of the Aegean Sea, the mountain and the neighboring island Kimolos.
Milos (or Melos) is a volcanic Greek island and belongs to the island group of Cyclades, in the Aegean Sea southeast of mainland Greece. Cyclades are one of the island groups which constitute the Aegean Archipelago. The name refers to the islands forming a circle (``circular islands``) around the sacred island of Delos. The municipality of Milos also includes the uninhabited offshore islands of Antimilos and Arcadies. The combined land area is 160.147 square kilometers (61.833 sq mi) and the 2011 census population was nearly 5.000 inhabitants.


Cyclades islands are peaks of a submerged mountainous terrain, with the exception of two volcanic islands Milos and Santorini. The climate is generally dry and mild,. Milos is the southwestern most island in the Cyclades group. Milos has a Mediterranean climate with mild, rainy winters and warm to hot dry summers.
The vineyards, most of which are located near by the Kostantakis wineny are trained low in traditional bush shape (cup- shape). The soils are sandy clay and has a very distinctive geology, meaning that the rocks and minerals its soil and subsoil are made of point directly to its special creation. Some rocks and minerals of the island are very characteristic and owe their origin to volcanic processes.
An interesting blend of varieties are found in Kostantakis vineyards , including Assyrtiko, Monemvasia , Roditis ,Savatiano, Malagousia, Mavrotragano, Mandilaria, Mavro Aidani and Moscato (Muscat).

Open in the evening only, this is the only winery on Milos, built into a cave. Small production of 10,000 bottles a year, most gets drunk on Milos. The wine is delicious and fruity, the information very interesting and the 'bartender' very friendly and keen for you to try everything (6 wines in all). I definitely recommend this.

What a winery! Had our eye on it from the day we arrived in Milos. A small family run winery in Pollonia, a pleasant 600 mtr walk from centre of town through narrow local roads and private houses. ( see pics) . The winery is hidden away from the main town, right next to the Kostantakis family residence. We met Petros Kostantakis ( 3rd generation owner of the winery) at the reception. Enterprising young lad,he showed us around the modest sized cellars neatly stacked with wine bottles ready to be labeled. Tasted 3 excellent wines there. Said, they were planning expansion of the brand and production over the next 2-3 years. We wish him and his family all the best!

My wife and I visited Kostantakis winery several times during our stay in Milos. We were staying at the Kostantakis Residence - the accommodation run by the same family that owns the winery. The winery is in its infancy, having produced wines commercially for only six years. Nevertheless, the petite winery exudes a unique Melian charm and the wines they produce are very drinkable. We particularly enjoyed the semi-sweet rose wine. Our host, Petros, was very friendly and knowledgeable about the wines and unique history of the cave around which the winery was born. Best of all, the wine tasting is free and the bottles for sale are very reasonably priced. Highly recommended!

We just stumbled upon this winery on our self-guided driving tour of Milos. We saw the signs and the idea of a cave winery was intriguing. We were there with one other couple and enjoyed tasting several of their wines and learning about the history. The wine is much lighter and fruitier than what we would see in the US (especially the red) - but we bought a few bottles and are able to enjoy it stateside!
