The wide variety of microorganisms has been identified in many wine-making countries on the berries of grapes. These are yeasts of different families, forms and kinds, bacterium, mold fungi. In the article, we present the results of investigating species composition of microflora of berries of white and red types of grape, which grows in different economies of the Krasnodar region and the republic of Abkhaziya. The sowings onto the elective media were conducted for the development of entire spectrum of yeast. The grown colonies after preliminary microscoping were separated into the cultures and subjected to testing according to the culturalmorphological signs, being guided by determinants and benefits. It was established the specific variety of microflora on the surface of the berries of grapes of all investigated types, without dependence on the place of their growth. Obtained data showed that the group of yeast, which constantly is present in the complex of the epiphytic microorganisms of grapes of Saccharomyces, Pichia, Hansenula, Hanseniaspora was characteristic for all types of grapes in all investigated regions. The heterogeneity of the taxonometric composition of microflora is shown. Prevailed yeasts were of family Saccharomycetaceae, form Saccharomyces vini. A quantity of yeast of Saccharomyces vini decreases in a number of Myskhako-Caucasus-Fanagoriya, that as a whole will be coordinated with the climatic conditions. Only the type of Pinot nuar grapes had yeasts of Brettanomyces Dekkera. On the berries of Cabernets and Karaburnu we have discovered yeasts of Schisosaccharomyces acidodevoratus, causing acid-reduction. On the berries of the grapes, which grew in joint stock company APF “Fanagoriya” we haven’t revealed the presence of lactic acid bacteria Lactobacillus brevis and yeasts of the form of Schisosaccharomyces acidodevoratus. In the same farm the smallest quantity of yeastswreckers is noted, which we the forms of Pichia and Candida. In the microflora of Cabernets, Risling and, especially, Karaburnu grapes, we have found lactic acid bacteria Lactobacillus plantarum and Lactobacillus brevis. Lactobacillus plantarum. Among the bacteria the total quantity of coccic flora composes - 56 %, the rod-shaped - 44 %. Two types of active acetous bacteria are identified – Acetobacter aceti and Acetobacter xelinum. Especially high was their surface concentration on the berries of Kachich type of grapes
The article reviews the results of studying the influence
of mineral fertilizers on the qualitative indices of the
Merlot grape variety in the Anapo-Taman zone of the
Krasnodar region. The technology of cultivation of
grapes on the experimental plot was in accordance with
the accepted for the given zone and culture.
Agrobiological work was carried out at the optimal
time and had a high quality of execution. Grape bushes
are laid in a 3.0 x 2.0 m pattern. Formation - a twoshoulder
horizontal cordon. On the bushes we formed
the same load of shoots and bunches. Scheme of the
experiment: option 1 – no fertilizers (control); option
2-superphosphate with a mixture of potassium salt
(P90K90) from the autumn; option 3 –nitroammofoska
(N120P120K120) from autumn; option 4 – ammonium
nitrate (N60) in early spring. Analysis of the results of
studies on the study of biological features of growth,
fruiting, yield and quality of Merlot grape varieties on the background of the use of mineral fertilizers shows
their high efficiency in the conditions of the AnapoTamanskaya
zone of the Krasnodar region and can be
recommended for use in production conditions.
Mineral fertilizers ensures the receipt of dry bulk wine
of superior quality control sample (without fertilizers)
the concentration of tartaric acid 17.3 25.1 percent,
phenolic compounds 17.1 – 40.0 %, and alcohol
content of 7.2 and 9.3 %, titratable acids 11.8 and 13.7
%, given extract by 17.4 %, with a decrease of the
mass concentration of total sulfur dioxide and pH. The
most effective is the introduction of NPK

The article reviews the results of the study of the influence of treatment of Saperavi grapes with the growth regulators (Biodux and Avibif) on the quality of grape must and wine in the Anapо-Taman zone of the Krasnodar region
In this article chemical and technical characteristics questions of vine materials, received from protoclones of grapes of Saperavi grade - one of the basic classical grades of grapes selected in "Pobeda" Joint-Stock Company are taken up. Samples of grapes have been used for preparation of red table wines by mash fermentation on septum in workshop of micro winemaking of The North Caucasian zone scientific research institute of gardening and wine growing. They have not given vine materials identical on physical and chemical and organoleptical features. Samples with low productivity essentially differed on organoleptical qualities from other samples and had the highest sampling estimations that allows to take measures on loading regulation on a grape bush and correct quality of wine in further by means of methods of agricultural technics. For making high-quality table red vine materials it is recommended to use apple-lactic fermentation by means of oxygen-eating bacteria
Researches on non-root additional fertilizing of grapes with complex water-soluble fertilizer called Nutrivant plus have been conducted in corporation "Pobeda" in Temrjuksky area of Krasnodar territory on the implanted plantings of technical grade Rhine Riesling. In the test, the following kinds of Nutrivant plus were used: oleiferous (N0P20K33), sugar beet (N0P36K24), grapes (N0P40K25), universal (N19P19K19), grain (N6P23K35). Each mark of Nutrivant plus contained a certain set of microelements. The test consisted of six variants:1 variant - without additional fertilizing(control); 2 variant: grapes - before flowering, grapes - a growth phase of berries (a berry about a pea), oleiferous - the beginning of maturing of berries; 3 variant: universal - before flowering, universal - a growth phase of berries (a berry about a pea), oleiferous- the beginning of maturing of berries; 4 variant: grain - before flowering, grain - a growth phase of berries (a berry about a pea), oleiferous- the beginning of maturing of berries; 5 variant: Sugar beet - before flowering, a sugar beet - a growth phase of berries (a berry about a pea), a sugar beet - the beginning of maturing of berries; 6 variant: universal - before flowering, grain - a growth phase of berries (a berry about a pea), grapes - the beginning of maturing of berries. Norm of the expense of fertilizer is 3 kg/hectares. The expense of a working liquid - 700 l/hectares. The result was, that in the third, fourth and fifth variant of the test the increase in a crop from a bush happened accordingly on 7,5, 13,8 and 17,8 %. The maximum increase of a crop in the fifth variant was accompanied by increase in mass concentration of sugars in juice of berries on 0,6 g/100 см3и decrease titratable acidities for 0,6/dm3 As a result triple not root additional fertilizing of grapes plants grade Riesling with Nutrivant plus (universal - before flowering, grain - in a growth phase of berries and grape - in the beginning of maturing of berries) promoted more optimization of a water mode of leaves, increase in weight of a cluster, a crop from a bush and productivity, mass concentration of sugars and phenolic substances in juice of berries
The article reviews the results of the studies of the influence of treatment of Saperavi vines with lignohumate of "A" grade on the quality of grape must and wine in Anapо-Taman zone of the Krasnodar region
There was given the review of the results of the study
in the conditions of the Anapa-Taman zone of the
Krasnodar region of the influence of the treatment of
vines of Saperavi of lignohumates of the grade "В"
(“LG-B Bio”, “LG-B Best Bio”, “LG- Best L”) on the
quality of must and wine materials. The technology of
the grape cultivation on the experimental plot
corresponded to the adopted technology which is used
in the JSC "Pobeda" of Temryuk District and was
widely accepted for the keeping of fruit-bearing
plantations of the zone of uncovered viticulture.
Agrobiological works were carried out at the optimum
terms and were of high quality. Vines of the third- year
of life, embodied by the scheme in 3,0 x 1,5 m. The
forming is a one-sided Guyot with a height of the trunk
in 60 cm. On bushes there was formed the same load
shoots and clusters. There were carried out the
treatments of grape leaf surfaces by the solutions of
lignohumates twice: the 1st – before the flowering and
the 2 nd in the beginning of the formation of berries (in
20 days after the first one). The spraying was carried
out in the early morning hours. The accounting of the
grape harvest and the sampling for the determination of
the quality of must and wine materials (10 kg per each
type) was conducted in September 20, 2012. The
technological and physical-chemical analyses were
carried out in the shop of mini winemaking and in the
accredited testing laboratory of the grape processing of
the scientific center of the winemaking SCSRIHGG of
the RAAS. The preparations "LG-B Bio", "LG-B
Super Bio" and "LG-B Best A" as grape growth
regulators have the equal and stable effect
The article reviews the results of the study of the influence of treatment of vines of Saperavi with lignohumate of grade "A" on its uvological and fruitful properties in the Anapо- Taman zone of the Krasnodar region
We have presented opportunities to improve the nutritional value of wine production: improvement of biogenetic soil, using organic fertilizers. The nutritional value is ensured by not only high-quality biochemical diversity of berries, but also the safety of products that do not contain toxic inclusions. Bio-fertilizer stimulates the biotransformation of toxic soil residues to replenish soil nutrients for the plant, providing grape raw material with biologically active substances and improves the nutritional value of wine products. Food safety of grapes is ensured by reducing it residues of hazardous chemicals migrating from the soil into the plant and the grapes. It has been established, that after 3 years of application of biofertilizers we significantly improved food safety and quality in the biochemical parameters, especially important for the classic wine grape varieties. The soil content of toxic residues in grape raw material is reduced to 50%, the amount of organic acids increases by: 4,22 mg/dm3(Gallic, coffee acid, chlorogenic; 0.7 g/cm3 amber; of 1.33 mg/dm3 ascorbic; 0.25 mg/dm3 nicotinic
The article is dedicated to the study of new complex growth regulator called Zerebra agro and its influence on agrobiological and technological indicators of grapes. Studies were conducted in the Anapo-Taman Wine Growing Zone of the Krasnodar region (PAO Pobeda, Temryuk District). The fruit-bearing plantations of the white variety Viorica were cultivated three times during the vegetation period: before flowering (May 27), after flowering (June 20), the growth phase of berries (July 18), berries ripening (August 13) 200 ml / ha. Application of the growth regulator Zerebra agro resulted in a significant increase in the average mass of the bunch (by 11.5%), due to an increase in the number of berries (by 12.6%), yields from the bush (by 11.8%) and yields of plantations (by 1.17 tons or %). The increase in the experimental variant of the vine harvest was not accompanied by a decrease in the sugar content of the berries juice and an increase in the titrated acidity. The use of Zerebra agro allowed to reduce the degree of death of the central buds of wintering eyes at two and a half times, also to increase the coefficients of fruiting and fruit bearing, as well as the proportion of eyelets with two inflorescences and more. The greatest decrease in the death of the central wintering buds, as well as an increase in the embryonic fruiting index, was observed in the zone of 1-5 buds, which makes it possible to apply in the experimental version a short pruning length of fruit vines and to abandon the dry garters of fruit shooters
