| Summary: | The aim of this study is to evaluate the impact of Botrytis cinerea, a noble rot, on the aroma components of Amarone, a dry red wine produced from withered grapes. A comparative analysis of wines obtained from manually selected healthy and botrytized grapes was done. Aroma analysis revealed that most compounds varied significantly according to the percentage of botrytized berries utilized. Botrytized wines contained less fatty acids and more fruity acetates than healthy wines. A positive correlation between the content of N-(3-methylbutyl)acetamide, sherry lactone and an unidentified compound and the level of fungal infection was also observed. The results indicate that noble rot can significantly modify important aroma components of Amarone wine. |
