Investigation on the Oenological Applicability of Bioprotection in Tokaj Wine Region
Zsuzsanna Bene

Abstract
Viticulture and oenology are increasingly focused on environmental sustainability, food safety and health awareness. Reduced or zero sulphur in wine preservation is one of the key aspects of organic production, where bioprotection cultures are used to prevent oxidation, inhibit the growth of harmful microorganisms. Particular attention should be paid to the microbiological protection of noble rot raw materials, because the presence of Botyrtis cinerea fundamentally alters the composition of the associated microflora and allows bacterial growth resulting changes in chemical composition associated with increased amounts of sulphuric acid-binding ketoacids, so that there are certainly a number of advantages to be gained from reducing or replacing sulphur-dioxide by bioprotection. In the present study, the experience with the application of Erbslöh Oenoferm® MProtect Metschnikowia pulcherrima is shown in the treatment of raw materials with different degrees of noble rot in the Tokaj wine region.
