The dependence of the productivity of the Riesling
Rennel vineyards and the quality of table wine from it
under the conditions of the Anapa-Taman Winegrowing
Zone was studied. It is established that the
vineyards of the Riesling Rhine variety are planted
with the highest yield, planted according to the
scheme of 3.5x1 m. In this embodiment, at a density
planting shrubs 2857 pcs. / Ha, the yield of grapes was
the highest - 131.4 c / ha. Maximum accumulation of
sugars in the grapes observed in the variants with a
width of 2.5 m aisle highest extract content from
different wine stocks options with row spacing of 2.5
m where the amount of extractables amounted to 17.1
- 19.2 g / dm3
. The increase in the total concentration
of aromatic compounds of up to 540 mg / dm 3
helps
to improve the quality of white table wine, and further
growth of aromatics to 1090 mg / dm3
- it reduces the
organoleptic evaluation. High tasting marks (7.88-8.29
points) received wine materials from sites having a
spacing of 3.5 m. Thus, considering the quality of the
wine, the cost of planting material, laying and care of
vineyards, it is worth considering the 3.5x1 planting
scheme , 5 m more suitable for the production of
quality table wines in the Black Sea agroecological
zone of viticulture in the south of Russia
Currently, more and more popular in the world are indigenous grape varieties. Now in Russia and abroad there is a growing interest in Krasnostops - a high quality indigenous red grape varieties of technical direction. The object of research was the red technical grape variety called Krasnostop Anapa and Krasnostop AZOS, grown in Anapa ampelocalamus and wine from them. As a control, we used two classic grape varieties of varying degrees of saturation in color and extract content of the wines of Cabernet Sauvignon and Saperavi. The article presents the materials of years of research – agrobiological, technological and economic indicators of technical grades of grapes of selection of the Anapa station – Krasnostop Anapa and Krasnostop AZOS. The amount of anthocyanins in wine from Anapa Krasnostops has superior data for these components in the control options. The mass concentration of phenolic substances and their monomer forms in wine materials of grape varieties Krasnostop AZOS and Krasnostop Anapsky is higher than in the quality control of red wines-Cabernet Sauvignon, which indicates a high accumulation of phenolic substances in new grape varieties. In the years of the study of Krasnostop AZOS and Krasnostop Anapsky on organoleptic properties of wine has received good performance - and of 8.78 8.73 points. The brands of wines developed on their basis will fill up a number of high-quality table and liqueur red wines in the Russian market. These grapes have high potential and great prospects in the light of the global trend of their use in winemaking. All this allows to recommend these grades for wide introduction into production in the southern wine-growing regions of Russia
The studies revealed that the application of spirits as a
strength agent of 91.0 - 96.6% in special wines
contained more vitamin-like substances than wine,
alcoholized with double-distilled water with 75%
alcohol concentration. The highest marks for tasting
wines were given to the options made with the use of
rectified grain origin alcohol as an agent of alcohol.
Application of double-distilled water wine leads to
accumulation of unnecessarily high undesirable
groups of compounds such as methanol and fusel oil,
thereby reducing the quality of the wine. Organoleptic
parameters were the best for selection of wines from
Anapa ZOSViV - Dionysus and Krasnostop EPA, as
well as - Cabernet Sauvignon. We can conclude that
for the production of high-quality red dessert wines
we need, along with the classic varieties, wider use of
new autochthonous varieties using alcohol agents of
rectified grain origin
