The article presents the results of studies, carried out in 2018-2020 in soil and climatic conditions of viticultural zone of the South Coast of Crimea on wine grape variety ‘Cabernet-Sauvignon’. It was established that double application of national chelated micronutrient fertilizers Tiaton and Chelaton Extra for foliar dressing of grapes contributed to an increase in the average bunch weight by 9.3-15.3 g (10.3-16.9%), shoot productivity by 10.4-17.1% and cropping power by 0.6-1 t/ha (10-16.7%) in comparison with the control. It was experimentally determined that test treatments with Chelaton Extra preparation led to a significant increase in the average length of annual shoots by 13.3 cm (9.3%) and a gain in the green matter of bushes by 265.9 cm3 (12%). Using of the studied micronutrient fertilizers against the background of increased grape productivity positively influenced the process of sugar accumulation and ensured the value component at the control level. The studies have proven that double treatment with Chelaton Extra fertilizer contributed to an increase in the mass concentration of phenolic substances in wine by 10.7%.

The article presents the results of studies of 2019-2020, carried out in the soil and climatic conditions of Crimean Mountain-valley viticultural zone on table grape variety ‘Italia’. It was experimentally determined that five-fold foliar treatment of grape plantations with gel fertilizers has led to a significant increase in the average length of annual shoots by 15 cm (9.2%) and an increase in the green matter of bushes by 165.1 cm3 (9.1%). It was found that using of preparations of experimental system of mineral nutrition manufactured by Agrinos and Lima-Europe companies during two growing seasons of grape plants has led to an increase in the average bunch weight by 42.9 g (7.4%), shoot productivity by 8.1% and an increase in the cropping capacity by 1.8 t/ha (10.2%) in comparison with the control. Using of the studied mineral gel fertilizers against the background of increasing grape productivity did not affect the process of sugar accumulation and the level of titratable acids. The studies showed that two-year fertilizer utilization of the studied system of mineral nutrition contributed to a significant increase in organoleptic characteristics of table grapes.

An urgent task of today for grape growers is to find effective ways to achieve the compliance of conditional parameters to phenolic ripeness of grapes while maintaining high cropping capacity. In this study the influence of foliar treatment of grapes with nitrogen-containing preparations "Siamino Pro 500" on productivity and phenolic maturity of ‘Cabernet-Sauvignon’ grape variety was investigated. Studies were carried out during 2018-2019. Grape maturity degree was assessed by the Glories method, based on the determining of the total and extractable anthocyanin potential of grapes. It was shown that, as a result of the experimental scheme of processing, the cropping capacity increased by 10- 14%, as well as the bunch weight - by 13 - 16%. Use of the preparation contributed to the onset of technical maturity of grapes at the earlier period compared to the control. The content of anthocyanins extracted from the skins was 49- 56%. Experimental grape samples were characterized by a higher content of titratable acids (by 1.4 and 1.2 g/l) and a lower sugar accumulation (by 9 and 16 g/l). Positive influence of the experimental scheme of processing on organoleptic properties of wines was observed.

Сложные эфиры являются важной составляющей в сложении букета коньяков, в количественном отношении уступая только высшим спиртам. Уровень их содержания в коньячных виноматериалах и дистиллятах зависит от многих факторов (сорта винограда, агроэкологических условий его произрастания, технологии получения виноматериалов и дистиллятов и др.). В связи с этим исследования, направленные на регулирование комплекса ароматических веществ коньячных виноматериалов и дистиллятов с целью повышения их качества являются актуальными. Представленные в статье результаты исследований позволили оценить влияние некоторых физико-химических и технологических факторов на ароматобразующий состав коньячных виноматериалов и дистиллятов. Установлено, что с повышением степени зрелости винограда в коньячных виноматериалах образуется больше средних эфиров. Наиболее существенный их прирост в виноматериалах установлен при массовой концентрации сахаров в винограде 162-175 г/дм3. Выявлено, что технологические обработки сусла оказывают положительное влияние на состав ароматобразующих веществ виноматериалов. Эффективность обработок возрастает при содержании фенольных веществ в сусле более 400 мг/дм3. Изучено влияние 12 рас дрожжей из КМВ ФГБУН «ВННИИВиВ «Магарач» и установлена целесообразность использования рас дрожжей вида Saccharomyces oviformis, обладающих повышенной способностью к синтезу эфиров. Показано, что брожение сусла без доступа кислорода воздуха способствует повышению содержания в виноматериалах и коньячных дистиллятах суммы летучих компонентов, в т.ч. средних эфиров. Результаты исследований могут быть использованы для оптимизации технологических режимов и параметров производства коньячных виноматериалов и дистиллятов с целью повышения их качества. Esters are the essential components in the composition of brandy bouquet, in terms of quantity giving place only to higher alcohols. Their level of content in brandy base wines and distillates depends on many factors (grape variety, agroecological conditions of growing, production technology of base wines and distillates, etc.). In this regard, the studies aimed at regulating the complex of aromatic substances of brandy base wines and distillates in order to improve their quality are relevant now. The research results presented in the article made it possible to assess the effect of some physicochemical and technological factors on the aroma-producing composition of brandy base wines and distillates. It was found that increasing of the degree of grape maturity raises the formation of medium-chain esters in brandy base wines. The most significant increase of esters in base wines was established at mass concentration of sugars in grapes - 162-175 g/dm3. It was revealed that technological processing of the must positively effects the composition of aroma-producing substances of base wines. The effectiveness of the processing increases when the content of phenolic substances in the must is more than 400 mg/dm3. The influence of 12 yeast races from the Collection of Microorganisms of Winemaking of the FSBSI Institute Magarach was studied, the expediency of using yeast races of the Saccharomyces oviformis species, possessing an increased ability to synthesize esters, was established. It was shown that must fermentation without the access of air oxygen contributes to an increase in the content of the sum of volatile components, including medium-chain esters, in base wines and brandy distillates. The research results can be used to optimize the technological modes and parameters of production of brandy base wines and distillates in order to improve their quality.

AbstractIn the period 2011–2013 a technological characteristic of the Ukrainian clone Aligote 61-6 was made at the Institute of Viticulture and Enology – Pleven. The Bulgarian candidate-clone Aligote N 10 was used for control. During the grapes ripening, the dynamics of sugar accumulation was monitored. Upon technological maturity the indicators of the yields were accounted and mechanical analysis was performed. The chemical composition of the must, the obtained wines and their organoleptic qualities were analyzed. In its mechanical composition, Aligote 61-6 was typically wine one and it did not differ significantly in the texture and structure of the cluster and berry from the control. The theoretical yield of both clones was high. They exhibited good sugar accumulation and similar acid content. Grapes from the control had better technological indicators for obtaining wines of optimal chemical composition and quality. In the 2011 and 2013 vintages, the control wines exceeded those of the Ukrainian clone in terms of sugar-free extract content. The experimental wines Aligote N 10 had higher titratable acidity compared to the Ukrainian clone. The difference in the phenolic substances ratio and the colour intensity in the samples from both clones were insignificant. The control wines were superior in their organoleptic qualities to those of the Ukrainian clone.

В стрессовых погодных условиях применение минеральных удобрений при внекорневых подкормках оказывает существенное влияние на рост и развитие виноградных растений, способствует повышению урожайности и улучшению качества продукции (содержание сахаров, титруемых кислот, фенольных веществ, витаминов, сохранности продукции и т.д.). В статье приводятся результаты исследований по изучению влияния органического удобрения природного происхождения Изабион на продуктивность и качество урожая винограда технических сортов Алиготе, Бастардо магарачский и Шардоне в почвенно-климатических условиях Юго-западной виноградарской зоны Крыма. В ходе проведения исследований установлено, что применение изучаемого удобрения способствует повышению средней массы грозди на 15,8-40 г, урожая с куста - на 0,8-1,4 кг и урожайности винограда - на 1,8-2,9 т/га в сравнении с контролями. Экспериментально определено, что опытные обработки привели к существенному увеличению средней длины побегов в среднем на 7,7 % и прироста вегетативной массы на 11,8 %. На фоне применения исследуемых систем питания отмечено увеличение концентрации сахаров в соке ягод на 11-18 г/дм(5,7-12,1 %). При расчете экономической эффективности технологии выращивания технического сорта винограда Алиготе установлено, что двукратная внекорневая подкормка минеральным удобрением Изабион снижает фактическую себестоимость произведенной продукции в среднем на 19,7 % и повышает рентабельность производства на 39,5 %. Using of mineral fertilizers in foliar dressing in stress weather conditions significantly effects growth and development of grape plants, promotes an increase in cropping capacity and product quality (content of sugars, titratable acids, phenolic substances, vitamins, product safe-keeping, etc.). The article presents the results of studies on the effect of natural organic fertilizer Isabion on the productivity and quality of grape yield of wine varieties ‘Aligote’, ‘Bastardo Magarachskiy’ and ‘Chardonnay’ in the soil and climatic conditions of the South-West viticultural zone of Crimea. In the course of the research it was found that using of the studied fertilizer contributed to an increase in the average bunch weight by 15.8-40 g, the yield per bush - by 0.8-1.4 kg, and the cropping capacity of grapes - by 1.8-2.9 t/ha in comparison with controls. It was experimentally determined that test applications have led to a significant increase in the average shoot length by 7.7% and in the green matter by 11.8%. Against the background of using the studied food systems, an increase in the concentration of sugars in the juice of berries by 11-18 g/dm (5.7-12.1%) was registered. When calculating the economic efficiency of wine grape variety ‘Aligote’ growing practice it was found that double foliar dressing with Isabion mineral fertilizer reduced actual cost of production by an average of 19.7% and increased profitability of production by 39.5%.

Систематизированы современные литературные данные о направлениях повышения качества отечественных игристых вин. Для увеличения выхода сусла рекомендовано использование пневматических мембранных прессов. Установлено, что использование мембранного пресса «Diemme Velvet 150» позволяет увеличить выход качественных фракций сусла до 68,2 дал/т. При повышении выхода сусла из 1 т винограда в получаемых виноматериалах происходит увеличение концентраций галловой, сиреневой, кафтаровой, каутаровой кислот, (+) - эпикатехина, кверцитина, кверцитин-3-0-гликозида, процианидинов, полимерных флаваноидов при одновременном снижении концентрации (+) - Д-катехина. Разработан многокритериальный показатель контроля качества виноматериалов, полученных из сусла при различном его выходе из 1 т винограда. Установлено, что лучшими по пенистым свойствам, ароматобразующему комплексу и органолептической оценке являются сортовые виноматериалы Каберне-Совиньон и Рубиновый Магарача, приготовленные с использованием штамма дрожжей 47-К. Приведены оптимальные технологические схемы обработок виноматериалов для белых игристых вин. Сделан вывод о том, что сахаросодержащие компоненты виноградного происхождения целесообразно применять вместо тиражного ликера для повышения качества игристых вин. Установлена корреляция между массовой концентрацией полимерных форм фенольных веществ и значением показателя максимального объема пены (V): для розовых игристых вин - 0,777, для красных игристых вин - 0,834. С целью повышения качества игристых вин рекомендуется применение автолизатов винных дрожжей, полученных на установке ВА-0,6 для кавитационной обработки дрожжевой массы. Приведен перечень разработанных и утвержденных СТО (стандартов организации) для определения специфических показателей при производстве игристых вин. Present-day literature data on the directions of improving the quality of locally produced sparkling wines are systematized. To increase the must yield, using of pneumatic membrane pressing machines is recommended. It has been established that using of membrane pressing machine Diemme Velvet 150 allows increasing the yield of high-quality must fractions to 68.2 daL/t. With an increase in the yield of must per 1 ton of grapes, an increase in the concentrations of gallic, lilac, caftaric, cautaric acids, (+) - epicatechin, quercitin, quercitin-3-0-glycoside, procyanidins, polymer flavonoids with simultaneous decrease in the concentration of (+) - D-catechin in the resulting base wine is observed. A quality control multi-criteria indicator of base wines obtained from must at its different output per 1 ton of grapes was developed. It was established that varietal base wines of ‘Cabernet-Sauvignon’ and ‘Rubynovyi Magaracha’, prepared using the 47-K yeast strain, are the best in terms of foaming capacity, aroma-producing complex and organoleptic evaluation. The optimal technological schemes of base wine processing are presented for white sparkling wines. It is advisable to use sugar-containing components of grape origin instead of tirage liqueur to improve the quality of sparkling wines. A correlation between the mass concentration of polymeric forms of phenolic substances and the value of maximum foam volume indicator (V) was established: for rose sparkling wines - 0.777, for red sparkling wines - 0.834. In order to improve the quality of sparkling wines, it is recommended to use autolysed wine yeasts obtained at the VA-0.6 unit for yeast mass cavitation treatment. A list of developed and approved STOs (standards of organizations) for determining specific indicators in the production of sparkling wines is given.

Preserving rare grapes is not just a matter of variety. Recent dna research has shown that unusual and unknown grape varieties provide clues to wine history. During the centuries, 525 Georgian grape varieties had been known but most of them were degenerated. Nowadays, more than 437 rare Georgian vine varieties are preserved in the geo 038 collection of Agricultural Research-Scientific Center, established in 2014 under the Environment Protection and agriculture ministry. Study of the genetic pool of Georgian grape varieties determine the sustainability of the sector and enrichment of the modern wine market. For this reason the studies of the rare aboriginal grape varieties have begun by their ampelography, phenology, chemical, and oeno-caprological characterizes. The aim of this study is to investigate rare, Georgian, aboriginal wine-grapes by their ampelography, chemical and oenolo-caprological characterizes, and to offer different style and aroma wines to the market, enriching the modern wine assortment. The present study investigated firstly the rare Georgian aboriginal grape variety (Chvitiluri) by its characterizes. In this study grapes caprologycal indication, dynamic development of the sugar accumulation, TA and pH in berries, polyphenols extract in skin and seeds, and phenolic compounds were determined. The grape has been compared with Georgian and French wine-grapes and their products as well. The results show that the grape variety - Chvitiluri, and vinification technique (aging on lee) have the significant impact on the total phenol content in wine. White varietal wine contents high alcohol 13,2%, total phenols 733-500mg/l. Wine has specific, varietal characterizes color, taste, aroma. This study indicates that the rare local, aboriginal variety presents the perspective sort for wine production and can be returned in wine production.

The climate changes in Murfatlar vineyard in recent years consist inthe increase ofmonthly average temperatures, recorded in both cold and warm seasons, accompanied by an irregular distribution of rainfall during the year, which significantly influences the growth of grapevine, the quality and production of grapes.Six representative cultivars were studied, three for white wines: Chardonnay, Columna and Muscat Ottonel and three for red wines: Fetească Neagră, Mamaia and Cabernet Sauvignon. In the last two years (2019-2020) warm winters and very dry summers have led to the onset of budburst, almost simultaneously for all the studied cultivars, followed by a very weak growth and development of shoots (2020) and an acceleration development of phenophases, mainly berween veraison and ripening. Water stress during the vegetative period, a hygroscopicity below 60% between July and August and low vegetative apparatus influenced the growth ofthe berries, resulting small grapes, and a very low must yield in 2020.Concerning the quality of grape production, the studied cultivars achieved more sugar concentrations in berries up to 35.8 g/L (in 2019) and 36.0 g/L (in 2020), higher than the values obtained in normal years. In the conditions of a pronounced dry climate manifested in the two years of study, the productions were below the normal level, especialy in 2020, achieving much diminished productions for all cultivars, except the Mamaia cultivar. The Mamaia cultivar had a positive reaction, registering an increase of production, that exceeded the multiannual value by 20% in 2020 andby 10% in 2019, the concentration of sugars in the must being above the average value obtained in normal years, exceeding by 3% and 9%, respectively, the multiannual average. Statistical calculations were done using SPSS Statistics 17.0, using mainly the Duncan test for a degree of significance of 5%.
