Zoning influence in chromatic parameters in Monastrell grape

La zonazione viticola rappresenta un importante strumento di indagine per valutare e interpretare le potenzialità produttive e qualitative di un territorio. Con l’obiettivo di studiare come l’ambiente influisca sulla qualità dell’uva nell’areale di Brisighella, sono stati monitorati, nelle annate 2007, 2008 e 2009, 14 vigneti per la varietà Albana e 38 per la varietà Sangiovese, rappresentativi di una area vitata di circa 1000 ha.

The aging potential of Burgundy chardonnay wines is considered as quality indicator. However, some of them exhibit higher oxidative sensitivity and premature oxidative aging symptoms, which are potentially induced by no-enzymatic oxidation such as Fenton-type reaction (Danilewicz, 2003). This chemical mechanism involves the action of transition metal, native phenolic compounds and oxygen which promote the generation of highly reactive oxygen species (ROS) such as hydroxyl radicals (OH) or 1-hydroxyethyl radicals (1-HER) from oxidation of ethanol. Such mechanism is involved in the radical oxidation occurring during bottle aging. According to Elias et al.,(2009a), the 1-HER is the most abundant radical in forced oxidation treated wines. Consequently, understanding its evolution kinetic in dry white wines is of great importance.

The dynamic evolution of some bioclimatic indices largely used to define the vocation of areas to grape growing was assessed over 43 years (1965-2007) in four sites of the Abruzzo Region (Central Italy).

Italy is the leader table grape producer country in Europe and the eighth worldwide (OIV, 2021). The italian production area is sized at approximately 47,248 hectares with a production of 9.66 million quintals of grapes. Apulia and sicily are the main producing italian regions which collectively account for over the 90% of the italian production area (istat, 2022).

REVINE is a 3 year European projected funded by PRIMA programme which proposes the adoption of regenerative agriculture practices with an innovative and original perspective, in order to improve the resilience of vineyards to climate change in the Mediterranean area. The potential for innovation lies in developing and combining new approaches that make agriculture more environmentally sustainable and enable a circular economy capable of improving farmers’ incomes. Primarily REVINE aims to improve soil health and biodiversity by promoting the multiplication of soil saprophytic microorganisms and the presence of useful microorganisms linked to the life cycle of the plant, such as rhizobacteria (PGPR) and fungi (PGPF) that promote plant growth which, in addition to increasing plant performance, increase tolerance to biotic and abiotic stresses.
