Aldehyde

Intermediate component between alcohol and acids. Thanks to a right quantity, especially in wine and by-product drinks, it emphasizes the bouquet. In Grappa the most representative substance is the acetic aldehyde; there are also the valerian aldehyde, the butyric acid, the exilic and the acetate. They organoleptically give an herbaceous flavour that can result negative if too plain.
