Assyrtiko is a white variety, indigenous to the island of Santorini, where the vineyard contributes to the picturesque aesthetic of the island’s landscape. Assyrtiko, however, is being cultivated throughout the Aegean Sea. It has been classified as a noble white variety, and is one of the most renown greek varieties internationally. It is a multi-dynamic variety that is able to give us fine wines, either dry or sweet, and allows a wide range of cultivation approaches and techniques as well as vinification at different stages of ripening.
The history of the grape variety
Assyrtiko
There are several theories regarding the origin of Assyrtiko, with the most convincing theory claiming that the name means "Assyrian", placing the roots of Assyrtiko somewhere in Mesopotamia (present day Iraq). This theory, however, is yet to be proven either genetically or scientifically, so for now it just remains a theory.
VINEYARD CULTIVATION
ASSYRTIKO GRAPE VARIETY
The presence of calcium carbonate that neutralizes the acidity of the soil, in connection with the pH that ranges from 7 to 8.5, is ideal for the absorption of most trace elements by the plant.
Calcium carbonate also improves soil structure, ensuring good drainage and good soil temperature. These soil characteristics contribute to the good phenolic and technological ripening of the grapes and therefore to the production of wines with rich structure and volume, intensity in colour and balanced acidity.
The vineyards in Dafnes area are located northeast of Psiloritis Mountain, which is the highest of the island, with an altitude 2456m. The relief of the wider area is formed by rolling hills, almost parallel to each other, extending from the northern part of the prefecture to the south at an altitude of 300-500m. The vineyards are planted on the slopes of these hills, east or west oriented.
The elongated valleys that are formed between the hills serve as natural canals, transferring the conducive chilled breeze from Cretan Sea to the center of the prefecture, maintaining the temperature at the slopes at very good levels all around summer. Rainfall is rare during the summer, so plants and grapes avoid virus infections.
The variety has been fully acclimatized in Dafnes. The great advantage of Assyrtiko at our area is that it matures properly, because of the beneficial microclimate.

GREEK LEGISLATION FOR ASSYRTIKO VARIETY
The characteristics of Assyrtiko wine
Assyrtiko variety gives us wine of high colour intensity, that differs depending on its age. It varies from pale yellow with green hews that gets more and more golden with the pass of time.
The unique aromatic bouquet combines some fresh aromas of citrus, with those of white fruits and herbs. The ageing potential is lead by the acidity that makes it last through time, developing a unique, intense palate of aging aromas.
In the mouth, we find the corresponding flavors to the aromas, a rich body and a crispy acidity that is typical of the variety.
Depending on the vinification method, it has an aging potential of 8-10 years. Regarding the dessert wines from the variety of Assyrtiko, because of the dehydration of the grapes under the sun, we are left with wines of high alcohol contents and well-rounded tannins.
Assyrtiko is considered as one of the finest and most noble greek white varieties.
