В статье представлены результаты двухлетних исследований по изучению влияния внекорневых подкормок гуминовым препаратом нового поколения GSN-2004 HUMILIFEтм (ОСН-2004) на урожай и качество винограда столового сорта Мускат янтарный и технического сорта Каберне-Совиньон в условиях Южного берега Крыма. По результатам исследований 2017-2018 гг. установлено, что внекорневые подкормки изучаемым препаратом разработанной нормой 4 л/га, способствуют увеличению урожайности винограда сорта Мускат янтарный в среднем на 23,9%, при этом повышение урожайности составляет 2,7 т/га. Урожайность винограда сорта Каберне-Совиньон увеличивается на 26,5%, при этом повышение урожайности составляет 2,2 т/га. Подтверждено положительное влияние внекорневых подкормок на показатели качества винограда сорта Мускат янтарный, которое выразилось в увеличении средней массы грозди у изучаемого сорта на 40,3%, увеличении массовой концентрации сахаров в соке ягод на 5,4% и увеличении значений глюкоацидометрического показателя (ГАП) на 15,6%. Положительное влияние внекорневых подкормок на показатели качества винограда сорта Каберне-Совиньон выразилось в увеличении средней массы грозди на 23,0% и увеличении массовой концентрации сахаров в соке ягод на 7,1%.The paper summarizes findings of a two-year study on the impact of foliar fertilizing with a new generation humic preparation GSN-2004 HUMILIFEтм (ОСН-2004) on the harvest and quality of ‘Muscat Yantarniy’ table grapes and ‘Cabernet Sauvignon’ wine grapes in the conditions of the southern coast of Crimea. The data of the 2017-2018 study established that foliar dressing with the preparation under study in the ratio of 4 l/ha increases the harvest of ‘Muscat Yantarniy’ grapes on average by 23.9%, or by 2 t/ha. The yield of ‘Cabernet Sauvignon’ grapes was increased by 26.5%, thus increasing the harvest by 2.2 t/ha. The positive impact of foliar dressing on quality indicators of ‘Muscat Yantarniy’ grapes was confirmed. Thus, the average cluster weight increased by 40.3%, total sugars in the berry juice increased by 5.4 %, and gluco-acidometric index increased by 158.06 %. The study confirmed the positive effect of foliar dressing on quality characteristics of ‘Cabernet Sauvignon’ grapes, as demonstrated by a 23% increase in the average cluster weight and a 7.1 % increase in the total sugars in the berry juice.

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%.

In order to study effect of oak sawdust on the quality of Kyoho wine immersed by fermented Cabernet Sauvignon residual, Kyoho wine aged without oak sawdust (KWO), including KWO1 and KWO2 according to immersed orders by fermented Cabernet Sauvignon residual, was taken as control to compare the effect of oak sawdust on quality of Kyoho wine (KO), including KO1 and KO2 according to aged orders by oak sawdust. During the 15 days of aging, physical and chemical indicators, such as chroma, tonality, and total phenol in wine were determined simultaneously by using a spectrophotometer, including tannin content by KMnO4 titration, once every 3 days. The results showed that the chromaticities of Kyoho wine were 3.21, 3.02, 4.46, and 3.71 for KO1, KO2, KWO1, and KWO2, respectively. Similarly, the hues were in turn 0.73, 0.68, 0.97, and 0.72, respectively. Tannin contents were 1601.5 mg/L, 1517.3 mg/L, 337.2 mg/L, and 115.6 mg/L; total phenol contents were 277.67 mg/L, 222.1 mg/L, 64 mg/L, and 79.8 mg/L. Therefore, the contents of tannin and total phenol from KO1 wine were all the highest values. The chroma and tone of the four types of wine showed an upward trend of “S.” The chromaticity and tone were the lowest for the KO2 wine and the highest for the KWO1 wine with the larger difference between KO2 and KWO1.

AbstractA substantial oenological literature exists on opinions of experts and neophytes as they relate to opinions about the quality of wines (Ashenfelter and Quandt, 1998; Cicchetti, 2004; Lindley, 2006). These opinions can be contrasted with factual binary questions about wine: Is it oaked? Does it contain sulfites? Is it filtered? Is the grape varietal Cabernet Sauvignon or Cabernet Franc? Syrah or Grenache? Pinot Noir or Gamay? Such factual binary issues are examined within the broader context of the various measures of factual judgment: Overall Accuracy (OA), Sensitivity (Se), Specificity (Sp), Predicted Positive Accuracy (PPA), and Predicted Negative Accuracy (PNA). The resulting biostatistical methodology derives from biobehavioral diagnostic research investigations. The purpose of this report is to apply this methodology to the discipline of oenology to compare wine judgments with wine facts. Using hypothetical examples, wine judges’ classifications of wines as oaked or unoaked were analyzed for their degree of accuracy. The results show that OA is a poor measure of the accuracy of binary judgments relative to Se, Sp, PPA, or PNA. The biostatistics of the problem could have wide-ranging applications in the design of future oenological research investigations, and in scientific research more broadly.

Riesling, Chardonnay, Shiraz and Cabernet Sauvignon grapes can make magnificent wines but there are also many other excellent wine varieties that for many of us are rarely experienced. Vines for Wines will expand the wine lover’s knowledge and appreciation of a great range of wines and help to explore their individual preferences for specific varieties, blends, flavours and styles. This book is based on the highly successful Wine Grape Varieties, which is an aid to identifying grape vines. Vines for Wines, however, focuses on wines from the average consumer’s point-of-view, introducing the different wine grape varieties and the wines made from them, including blends. Each variety is represented by a colour photograph of the grape variety, its current world plantings, wine produced and notes describing the varietal characters for each wine grape variety. The tasting terms and wine notes for each variety provide a benchmark for the consumer to assess the quality of wines they drink, and to allow them to share and compare their experiences confidently with other wine lovers.

Anthocyanin Pigments

The Dragasani vineyard is one of the most ancient existing in Romania being famous for obtaining red and white wines of the highest quality. The present study has performed during five years (2005-2009), focusing on the anthocyanin profiles of the autochthonous Novac grapevine cultivar, in comparison with Cabernet Sauvignon cultivar which, also provides wines of high quality. The obtained results put into evidence, a special potential and chromatic structure in case of the grapes and wines characteristics for these autochthonous cultivars, which are very closed to those shown by the Cabernet Sauvignon. For all the cultivars studied, the amounts of cationical flavidium within the anthocyanin matter do keep continuously was growing, while acidity decreased and glucides was accumulated. However, at some moment, these synthesis indices of the cromatical structure’s quality begin to decline. Depending of the viticultural year it is the genetical nature of the respective anthocyanin pigments to differentiate through the involvements of each of the 3 categories of pigments (yellow, red or blue). During the wine’s evolution (maturation and aging), due to the modification of its cromatical structure, the ratio between the yellow and red pigments does confer to the wine a colour nuance which continues to increase, significantly improving the wine’s visual attraction. For the autochthonous grapevine cultivars for red wines, their antocyanins potential their respective qualities do enable us to state that on the basis of the quality of the raw materials, wine types of high qualities could be created, being so endowed that they could bear as well an origin denomination.
