The actual flavor of grapes is formed by the few free aroma molecules already found in the pulp and in the skin, plus by those aroma molecules quickly formed by enzymatic/catalytic reactions. The review covers key aroma components of aromatic grapes, raisins and raisinized grapes, and the aroma components responsible from green and vegetal notes. This knowledge is used to explain the flavor properties of neutral grapes. The aroma potential of grape is the consequence of five different systems/pools of specific aroma precursors that during fermentation and/or aging, release wine varietal aroma. In total, 27 relevant wine aroma compounds can be considered that proceed from grape specific precursors. Some of them are immediately formed during fermentation, while some others require long aging time to accumulate. Precursors are glycosides, glutathionyl and cysteinyl conjugates, and other non-volatile molecules. info:eu-repo/grantAgreement/ES/DGA/T29 info:eu-repo/grantAgreement/ES/MINECO/AGL2017-87373-C3-1-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.082 2019 BIOCHEMISTRY & MOLECULAR BIOLOGY 98 / 296 = 0.331 2019 Q2 T2 1.614 2019 Biochemistry 2019 Q1 Molecular Biology 2019 Q2 info:eu-repo/semantics/review info:eu-repo/semantics/publishedVersion Lopez, Ricardo Universidad de Zaragoza (orcid)0000-0002-0730-6606 2009 750 Universidad de Zaragoza Dpto.
