Tokaj wine region is famous for its aszú wines, which are made of noble rotted raw materials. There is also a continuous change in the life activity of Botrytis cinerea as a result of climate change, which not only alters the rate of acidification but also its characteristic biochemical processes. Increasing sugar content is associated with a fructose excess, an increase in succinic acid, fumaric acid, citric acid, a change in the composition of phenolic compounds and an increase in phenolic acid content. This study examines the polyphenol content measured in the last 4 vintages and presents the typical phenolic acid composition.
