Nykteri means ‘harvesting at night;. This production is made from Assyrtiko and it is aged in oak barrels for three months. The results are a textured, nutty, and crisp white wine with a pleasant finish.
The estate vineyards of Koutsogiannopoulos Winery comprise 15 hectares of vines which continue to be cultivated in the traditional way of weaving them into the shapes of baskets or crowns. These vineyards lie in the areas of Vothonas, Megalochori, and Fira. Long term contracts with farming families on the island also bolster the amount of fruit available in this bare and sparse land. What makes the vineyards in Santorini unique is the volcanic soil on which they grow. The soil consists of white volcanic ash mixed with schist and limestone; it contains hardly any organic matter and is therefore poor in nutrients. The ash soil traps the moisture in the air during the nighttime and early morning hours, acting as a kind of reservoir, initially storing water and then providing necessary moisture to the vine. The combination of the especially hot and dry climate with the volcanic soil works to keep disease in check. Phylloxera cannot survive in the Santorini climate and so root stock is essentially original, with some of the oldest continually producing vines on the island estimated at 400 years old.
