Il sistema vigneto del Lago di Bolsena: caratterizzazione della produzione di Cannaiola di Marta

Abstract

[English version below]

Il comprensorio del Lago di Bolsena (VT) è un territorio ad elevata vocazione vitivinicola in cui il paesaggio della vite storicamente persiste e caratterizza la fisionomia dei luoghi. Qui gli agroecosistemi viticoli possiedono una valenza ecologico-ambientale, storico-culturale ed economica di rilievo. La ricerca condotta ha previsto la caratterizzazione della tipologia delle produzioni e degli ambienti di coltivazione di diversi vitigni locali, in particolare il vitigno autoctono Cannaiola di Marta, con l’obiettivo di salvaguardarne il valore biologico, valutarne la qualità in funzione dei microambienti di coltivazione e il ruolo nella definizione della fisionomia del paesaggio. Mediante indagine cartografica è stata condotta un’analisi diacronica a scala territoriale per evidenziare il ruolo dei vigneti nell’uso del suolo e nella definizione dell’ecomosaico ambientale. In vigneti rappresentativi dell’eterogeneità degli ambienti di coltivazione, il vitigno autoctono Cannaiola di Marta è stato caratterizzato con indagine ampelografia rispetto alla varietà certificata Canaiolo nero. La qualità della produzione è stata rapportata alla tipologia di suolo e alla variabilità fisiografica. Uno studio dell’architettura dei vigneti ha completato l’analisi dei modelli viticoli. I risultati ottenuti hanno evidenziato l’unicità della produzione della Cannaiola di Marta e la particolarità degli ambienti di coltivazione per una qualità superiore. E’ emerso il carattere di vulnerabilità di questa produzione dovuta alla frammentarietà dei vigneti, a fronte di un elevato valore storico-culturale degli impianti. Il sistema vigneto della Cannaiola di Marta si inserisce armonicamente in un ecosistema prezioso per la salvaguardia delle risorse ambientali e paesaggistiche di un territorio fra i più suggestivi del Lazio.

The northern part of the Lazio region, i.e. the area around the Lake of Bolsena, is highly vacated to grapevine production. Since the past, rural landscape has been characterized by vineyards, that represent still today a distinctive trait of this territory. Here vineyards exhibit economical, but also ecological, historical, biological and social functions. Nonetheless, vineyard surface is decreasing dramatically, with evident loss in biodiversity and landscape diversity. The study was carried out in order to characterized through a systemic approach the production of the local variety Cannaiola di Marta and its territorial contest. In order to preserve this production and the related landscape, the germplasm unicity was evaluated, the grape quality was tested in the highly differing physical environments, and the physionomy of the vineyards, as well as that of the rural landscape, was measured through cartographic elaboration. The research has proved that the investigated area is suitable for high quality and unique productions. It is also possible to attribute to these vulnerable vineyards a cultural significance, based on the employment of historic germplasm, on traditional vineyard traits and cultural practices. The viticulture of this territory is included in a equilibrated ecosystem, in which vineyards might preserve the environmental resources of one of the most agreeable territory of the Lazio region.

Effects of bottle closure type on sensory characteristics of Chasselas wines

Several winemaking operations, such as filtration, pumping, and racking, are known to potentially facilitate the incorporation of atmospheric O2 into the wine. Control of grape must oxidation is one key aspect in the management of white wine aroma expression, color stability and shelf-life extension. On the one hand, controlled must oxidation may help to remove highly reactive phenolic compounds, which otherwise could contribute to premature oxidation. And on the other hand, in certain cases of extreme protection of the must from O2 (e.g. pressing under inert atmosphere), it can help to preserve varietal aromas and natural must antioxidants.

Pesticide removal in wine with a physical treatment by molecular sieving

All along the winemaking process, conditioning and aging, wine is susceptible to be contaminated by different molecules. Contaminations can have various origins, related to wine microorganisms or as a result of an exogenous contamination. The aforementioned contamination of the wine can be caused by the migration of molecules from the materials in contact with the wine or by a contamination from exogenous molecules present in the air. Regardless of the source of the contamination, mainly two types of consequences can be observed.

Effect of irrigation regime on carbon isotope ratio (δ13c) in different grapevines

In Castilla-La Mancha as other winegrowing regions, vineyards suffer the effects of the global climate warming. Severe spring and summer droughts are increasingly frequent, which concur with the phenological stages most susceptible to water and temperature stress. Under these conditions, irrigation use is required in order to ensure the vineyard growing sustainability. However water resources are increasingly limited, for this reason is required to choose cultivars displaying high water use efficiency.

Influence of deficit irrigation on grapevine cv. “Touriga Nacional” in Douro region: A metabolomic approach

Aim: This study aimed to evaluate whether irrigation of Touriga Nacional in Douro Demarcated Region (DDR) can partly mitigate the negative impacts of ongoing climate change on grapevine yield and quality and its impact on plant metabolism.

Yeast diversity in Vitis labrusca l. Ecosystems

Although there are detailed studies on the microbiota of Vitis vinifera L. grapes, little is known about the diversity of yeast communities present in non-vinifera Vitis ecosystems (i.e., grapes and spontaneously fermenting grape musts). Potentially scientific and/or enological valuable yeast strains from these non-vinifera Vitis ecosystems might never be isolated from V. vinifera L. Using a standard culture-dependent strategy, we studied the population of yeast species during initial stages of spontaneous fermentation of V. labrusca L. (Isabella) grape musts. Rare non-Saccharomyces yeast species were recognized in Isabella, including Candida azymoides, Pichia cecembensis, Candida californica, Candida bentonensis, Issatchenkia hanoiensis and Candida apicola.
