Rapporti tra diverse tipologie di terreno e risposte produttive e qualitative delle uve Merlot e Carmenère nell’area DOC Piave

Abstract

[English version below]

Da anni la ricerca viticola sta orientando le sue attenzioni verso lo studio della vocazionalità degli ecosistemi viticoli, perché fulcro della produttività della vite e qualità dei suoi frutti. Dal 2007 anche l’area a DOC del Piave, situata nella parte orientale della regione Veneto, è oggetto di uno specifico studio.
Il lavoro ha messo a confronto due diverse tipologie di suolo, uno a tessitura fine (limoso –argilloso) più a sud dell’area DOC Piave e l’altro a tessitura più grossolana (ghiaioso –ciottoloso) nella zona più a nord. Entrambe le varietà coltivate erano allevate a Sylvoz, innestate su Kober 5BB. Lo studio ha verificato nella bacca il contenuto di sostanze coloranti, il contenuto in solidi solubili, dell’acidità totale, del pH oltre ai parametri produttivi e vegetativi quali: n° grappoli/vite, produzione uva/vite, peso medio del grappolo e il legno di potatura.
I risultati ottenuti nel triennio, hanno permesso di evidenziare come le caratteristiche del terreno abbiano influenzato nettamente sia le rese produttive sia la qualità delle uve. Qualità che per la varietà Merlot è stata superiore nei suoli limoso – argillosi, al contrario il Carmenère ha trovato il miglior adattamento nei suoli ghiaioso – ciottolosi. L’analisi sensoriale ha confermato i dati analitici del Merlot ma non pienamente quelli del Carmenère.

Giving the important effects of the environmental factors on the vine productivity and grape quality, a branch of viticulture research has been focusing on the relation between vines and their ecosystems for years.
The DOC Piave area, located in the eastern part of the Veneto region, was the object of a specific zoning study from 2007 to 2009.
The study compared two different types of soils, one located in the Southern part of the DOC Area has clay-loam texture, the other located further Nord has a gravelly texture. For both varieties the trellising system was Sylvoz and the vines were grafted on Kober 5bb. Sugar accumulation, pigments amount, total acidity and pH were determined along with vegetative and productive parameters.
The results confirmed that there exist a close relationship between soil and grape quality, but each variety responds in a different way: Merlot had the most interesting quality when grown clay-loam soils, while a different behaviour was found in Carmenere. The wine sensory score confirmed the grape analysis for Merlot, but only partially for Carmenere.

Spectral discrimination between Vitis vinifera and labrusca by spectroradiometric techniques

Brazil is one of the few countries where vineyards of Vitis labrusca and Vitis vinifera coexist in the same geographical spaces, due to complex processes of territorial occupation by successive waves of European settlers.

Oak wood influence on the organoleptic perception of red wine

Some wood substances such as ellagitannins (vescalagin, castalagin, grandinin, roburins (A, B, C, D, E)…) can be extracted during wine ageing in oak barrels. The level of these hydrolysable tannins in wine depends of the species and origin of oak wood as well as its treatment during barrel realization.

Effects of mulching with municipal solid waste (MSW)-compost on the soil microbiota and decomposition activity in a productive vineyard in Apulia (Italy)

Application of municipal solid waste (MSW)-compost as a mulching material in vineyards supports sustainable practices and aligns with both circular economy and zero-waste principles.

How do different oak treatment affect the sensory composition of Chenin blanc wines over time?

Wooden barrels have been the preferred method for oak maturation for wines, but the use of alternative oak products, such as staves and oak chips have increased in South Africa due to lower production costs. This study investigated the effect of different oak products used during fermentation and ageing on the sensory profile, degree of liking and perceived quality of a South African Chenin blanc wine. The different wine treatments included an unoaked tank control wine, wines matured in 5th fill barrels, wines matured in new barrels from three different cooperages, and wines matured in 5th fill barrels with stave inserts from two different cooperages.

The relationship between enzyme treatment and polysaccharide extraction in wine making, and subsequent sensory effects in Cabernet Sauvignon wines

AIM To determine the effect of both ripeness and enzyme maceration on the astringency and bitterness perception of Cabernet Sauvignon winesRecent work has contributed to a more detailed understanding of the grape cell wall deconstruction process from ripening through crushing and fermentation, providing a better understanding of what role polysaccharides play in post-harvest fermentation of grapes(1,2). Current research on glycomics in red wine making suggest polysaccharides are important sensory impact molecules (3–6). METHODSOur experimental system harvests Cabernet Sauvignon grapes at three different ripeness levels and makes wine both with and without enzyme treatment.
