Abstract/OtherAbstract:
The effects of the joint pre-fermentative maceration and hyper-oxygenation of Airén white must and wine on the phenolic content, chromatic characteristics, volatile composition and sensory characteristics, not previously described in combination, have been evaluated. A total of 20 phenolic and 149 volatile compounds have been identified and quantified for that purpose. As a consequence of the oxygen addition, the concentration of hydroxycinnamic acid derivatives and flavan-3-ols decreased (above all t-GRP and (+)-catechin) leading to color stabilization, but also decreased that of several volatile compounds with a great importance for quality aroma. The pre-fermentative skin maceration, previously applied to the hyper-oxygenation of Airén musts, provided the aforementioned color stabilization in the respective wine but also increased the content of short-chain fatty acid esters and terpenes and decreased the concentration of C6 alcohols. That combination of pre-fermentative treatments (skin maceration followed by must hyper-oxygenation) produced an improvement of the global impression of the final wine based on significant better scores of tropical fruit, body and herbaceous notes.
