“…To determine the total content of elements in BT, they were subjected to a microwave-assisted decomposition using a MARS 6 system (CEM, USA). BT mineralization was conducted using the scheme given in [3] . Nitric, hydrochloric and hydrofluoric acids of reagent grade or higher were applied in the analysis of BT samples.…”

“…The authors of [37] assessed the nature of the supply of metals in the soil-grape chain, taking into account three extraction forms of elements from soils: total, acid-soluble, and mobile. In addition to mobile forms, the grapevine can also extract poorly soluble compounds from the soil [38], and each grape variety forms its own individual elemental image due to the different natures of metal absorption.…”

The features for assessing the authenticity of wines by region of origin are studied, based on the relationship between the mineral composition of the wine, the grapes, and the soil profile (0 to 160 cm) from the place of growth of Cabernet Sauvignon grapes. Soil, grape, and wine samples were taken from the territories of six vineyards in the Anapa district of Krasnodar Territory, Russia. Using the methods of ICP-OES, thermal, and X-ray phase analysis, the soils were differentiated into three groups, differing in mineralogical and mineral compositions. The soil samples of the first group contained up to 31% quartz, the second group up to 25% quartz and 19% mixed calcite, and the third group up to 32% calcite and 15% quartz. The formation of the elemental image of the grapes was studied, taking into account the total content and mobile forms of metals in the soil. The territorial proximity of the vineyards did not affect the extraction of elements from the soil into the grape berry, and the migration of metals for each territory was selective. According to the values of the biological absorption coefficient, the degree of transition of metals from the soil to a berry was estimated. For K, Ti, Zn, Rb, Cu, and Fe in all berries, the coefficient was higher than 1.00, which means that the berry extracts contained not only mobile-form, but also difficult-to-dissolve metal compounds. The migration of macro-components from the soil to the berry was low, and amounted to 6–7% for Ca, 0.8–3.0% for Na, and 25–70% for Mg of the concentration of their mobile forms. For all territories, the maximum correlation between metal concentrations in grapes and soil was observed for samples from a depth of 0–40 cm. The discriminant model based on concentrations of Rb, Al, K, Sr, Co, Na, Pb, Ca, and Ni showed the formation of clusters in the territories of vineyard cultivation. The developed model allow the problems of identifying wines by region to be solved with high accuracy, using their elemental image.

“…Экстрактивность вина -важный показатель качества продукта. Она дает возможность судить о вкусовых качествах вина, его способности противостоять окислению и даже натуральности винодельческой продукции [11,12,13]. В зависимости от применяемых препаратов экстрактивность всех образцов виноматериалов Шардоне изменялась в пределах 21,5…25,7 г/дм 3 .…”

The research was carried out in order to study the effect of various foliar fertilizers on the productivity of grapes, the quality of the must and the taste characteristics of wine products. The work was carried out in 2019-2021 in Anapo-Taman climatic subzone of Krasnodar Territory. The scheme of the experiment included the following options: without fertilizers (spraying with water) - control; Gumel lux 0.1 kg/ha; Filloton 1.0 l/ha; Agrumax 1.5 l/ha. Spraying was carried out three times in the following phases: “loosening of inflorescences”, after the end of flowering and in the “growth of berries” phase. Objects of study: Chardonnay grapes, its must and wine material. The bushes were formed according to the two-armed Kazenava cordon system, the planting scheme was 3.0 m × 1.5 m. The soil of the experimental plot was soddy-calcareous, powerful, low-humus, light-clay granulometric composition, formed on tertiary saline clays. Fertility is below average. The supply of nitrate nitrogen and mobile phosphorus is low, and that of potassium is high. The treatment of Chardonnay grapes with the studied preparations had a different effect on its productivity and the technological qualities of the must. The highest yield was noted in the variants treated with Agrumax and Gumel Lux fertilizers - 9.83 and 9.50 kg/plant. The excess of their productivity over the control was statistically significant and amounted to 3.13 and 2.80 kg/plant, respectively, with an HSR05 of 2.7 kg/plant. The effect of the drug Filloton on the yield of grapes was much weaker and manifested itself only in the form of a trend. Treatment with organomineral fertilizer Gumel lux contributed to an increase in the sugar content of the juice by 10.4% and the preservation in the must of the acidity optimal for dry white wines - 7.0 g/dm3. Wine materials in the variants with the use of Phylloton and Gumel Lux fertilizers were the most extractive in the experiment, which was reflected in their taste qualities, which received estimates of 7.82 and 7.73 points, respectively. According to the ratio of yield/quality of wine material, foliar top dressing with Gumel Lux provided optimal results.
