3. Research object: physic-chemical and organoleptyc indexes of grapes, musts, wine materials and sparkling wines. Research objective: Improvement of white sparkling wine's technology based on the development of grapes suitability criteria. Methods: generally accepted and new certificated analyses methods of chemical and physic-chemical indexes of musts, wine materials and sparkling wines. Theoretical and practical results: indexes system of musts and wine materials has been elaborated. It includes all indexes according to acting standard documents as well as row of additional ones: mass concentrations of phenolic matters, including their polymeric forms, pH, indexes G, ?G, ? and specific indexes of sparkling and foamy properties. The complex index (Оср) of wine materials quality has been proposed for the first time. It allows to forecast the sparking wine's organoleptic estimate just after making wine materials: If Оср?0,8 - sparking wine's estimate will be 8,91 0,03 mark, if 0,8<Оср 1,2 - sparkingwine's estimate will be 8,82±0,03 mark and if Оср 1,2 - sparking wine's estimate will be 8,72±0,04 mark. The method rules "Method of determination of grapes suitability criteria for of sparkling wines' production" have been developed and approved by UAAS. The method have been passed entrance examinations in wine works of SPE "Niva" and NSC "IVaW called after V.E. Tairov", recommended for introduction in wine-making industry and included in "Recommendation on the improvement of sparkling wines' quality". It is scientifically grounded and recommended expansion of possible range of sugar mass concentration in grapes from 160 to 200 г/дм3. Expedience of the use of the Sukholimansky sort is scientifically grounded for white sparkling wines' production, that allowed to include it in the standards "Виноматеріали для шампанського України та вин ігристих" and "Виноматеріали для шампанського України та вин ігристих". Novelty: regulatory of forming of sparkling wines' quality depending on the chemical composition and physic-chemical properties of wine materials have been determined: mass concentrations of phenolic matters, including their polymeric forms, indexes G, ?G, ? and specific indexes of sparkling and foamy properties. On the basis of that the system of indexes have been offered for the first time, as well as integral index of wine material's chemical composition and properties. It allows to carry out the prognosis of white sparkling wines' quality (coefficient of the correlation -0,88). Conformities to the law of change of values of row of wine materials' indexes at growth of degree of maturity of grapes have been determined. Dependence between the degree of maturity of grapes and index (oxydality) in wine materials have been determined. At the increase of grapes' sugar mass concentration from 161 2 to 201 3 г/дм3 values of index in wine materials went down from 1,13 0,07 to 0,77 0,06 мВ.дм3/мг, that testified about increase of phenolic matters' oxydation. Implementation degree: The volume of introduction of the method rules "Method of determination of grapes suitability criteria for of sparkling wines' production" have been made 5 thousand bottles of white sparkling wines the capacity 0,75 дм3. Effectiveness: An economic effect from the use of the Sukholimansky white sort in production of white sparkling wines makes 0,55 hrn per one bottle (0,75 дм3). Sphere, branch of use: wine making; production of white sparkling wines.
