Historical Trubetskoy vineyards with total area of 200 hectares are located on the slopes of Kakhovka Reservoir within the Black Sea Valley of the East European Plain at 46 degrees 48 minutes North latitude and 33 degrees 21 minutes East longitude.
South-Eastern slopes, coming down to the water, – are the main area for growing grapes. Exposition of the slope with 16-degree angle is perfect for planting vines.
Experts of “Prince P.N. Trubetskoy Winery” made a thorough selection of saplings from the best nurseries of Italy and France. Starting from 2003 new vines of international grapes varieties Aligote, Riesling and Cabernet have been planted in the historic vineyards of prince Trubetskoy. These are the varieties, chosen by an experienced winemaker Golitsyn for the first plantings more than a century ago. In 2007-2008 Merlot, Sauvignon Blanc, Chardonnay, Pinot Noir and Pinot Blanc have been added to the varieties. In 2011 vineyards have been supplemented with Cabernet Franc and Petit Verdot, in 2012 – 5 hectares of Rhine Riesling, and in 2013 – 5 hectares of both Malbec and Syrah varieties. High quality of saplings and a well-developed root system enabled first grape harvest from the vines already in 2007. And after the first bottling in 2011 the wines of Trubetskoy of the new time have been produced. Now the vineyards are in optimal fruit bearing period, which can be proved by the quality of the crop. Outstanding wines, made of tasty and aromatic berries, make up the winery collections.
The geological structure of “Prince P.N. Trubetskoy Winery” soils consists of 2-3 layers of forest and 1-2 buried soils, underlain by reddish brown clay. The latter one lies on Neogene Pontian limestones at a depth of 15-40 m. Groundwater lies 25-30 m deep. Top-soil of terroir is represented by southern thin humus accumulated medium-loam black soil.
Perennial vines have been planted from 2003 to 2013. Experienced oenologists and soil scientists determined the best areas for planting of certain varieties, with the help of French consultants. As a result, each vine is located in the place, where soil and climatic characteristics meet its needs perfectly. “Prince P.N. Trubetskoy Winery” agronomists do not seek to increase the number of grapes, but are guided by the qualitative characteristics of each crop. According to the chief agronomist Andrey Vasilenko, rationing of vine yield secures high quality of wine, as the limited number of bunches on vine makes the grapes healthier (due to improved aeration), ensures higher concentration of sugars, extraction, aromatics.
One of the best ways to improve the quality is to reduce the quantity. This gold standard, used for production of great wines in France and the whole world, is also accepted at “Prince P.N. Trubetskoy Winery”. The norm of yield for red wine grapes varieties is 50-60 q/ha, and for white – up to 70 q/ha. The best time of the day is picked for harvesting grapes. As a rule, it is early in the morning, when the berries are still not heated up by the sun.
Climate of the winemaking region is temperate continental. The sum of active air temperatures higher than 10 °C amounts to 3300-3400 degrees, rainfall amount for the period with such temperatures comes to 200-220 mm, during the year – 330-380 mm. Average duration of vegetation period is 225-230 days. The rate of evaporation from the soil comes to 320-380 mm.
The unique climatic conditions of Khersonska oblast have been evaluated by the chief winemaker of the time prince Golitsyn. He noted Khersonskiy region as area with climate, suitable for viticulture. Sum of day and night temperatures and availability of water reservoir near the vineyards make climatic conditions of the region optimal for cultivation of grapes.
