Aroma Composition of Wines Produced from Grapes Treated with Organic Amendments

The application to agriculture of wheat-straw spent mushroom substrate amendments (compost/vermicompost) used grow Pleurotus ostreatus has been analyzed. study was conducted in a vineyard where the effect on (1) physicochemical properties soil and leaf (2) analytical characteristics aromatic composition wine were resulted an increase organic matter macronutrients (NO3−, P2O5 K2O) soil. With regard leaves, NO3− K2O contents those vines fertilized with vermicompost higher, metallic content same regardless treatment applied. analysis colorimetric parameters showed that there higher compounds red violet colorations case obtained after vermicompost. In addition, for this type wine, concentration volatile obtained. Thus, grouping aroma into series, greatest differences among wines rest fruit, floral, herbaceous, green fruit series. principal component clearly differentiated from wines, addition its effects values total polyphenol index, responsible brown tones.
