Influence of grapevine age on general physicochemical and phenolic parameters of Rabigato (<i>Vitis vinifera</i> L.) white variety: Results from three vintages

The preservation of the old vine heritage, combined with fact that vines could present greater resistance to biotic and abiotic factors, has led an increase in research studies about contribution age on grape wine quality. Thus, main goal this work was evaluate potential influence grapevine several general physicochemical phenolic parameters during maturation a Rabigato white variety. Therefore, grapes from two adjacent vineyards, difference 30 years (one 20 other 50 years, at beginning study) were studied. At technological maturation, results obtained for three consecutive vintages studied (2019 2021), analysed, do not seem indicate clear differentiation between musts younger older vineyards. However, phenolics, suggest be factor content, nevertheless totally confirmed by considered. With we will contribute expand knowledge impact composition.
