Zonazione aziendale nel territorio del Chianti classico e valorizzazione dei vini

Abstract

[English version below]

Nell’ambiente del Chianti Classico è stato applicato un progetto di zonazione aziendale con l’objettivo di valorizzare le produzioni dei diversi vigneti. In particolare sono stati individuati sette siti, sottoposti a studio particolareggiato per un triennio.
I parametri ecopedologici sono stati correlati ai dati fenologici e produttivi, con particolare riguardo alle sostanze coloranti. I vini ottenuti nelle varie tesi sono stati sottoposti ad analisi sensoriale allo scopo di valutare le potenzialità dei vitigno Sangiovese seconda diverse tecni­che di vinificazione, sia in legno che in acciaio.
I risultati sottolineano la variabilità fenotipica del Sangiovese, in relazione alla struttura fisica dei suoli esaminati. In particolare l’accumulo degli zuccheri risulta dipendere dalle caratteristiche del suolo, mentre il contenuto acidico risulta maggiormente influenzato dal­l’annata. ln condizioni climatiche simili i migliori risultati sono stati ottenuti in suoli ricchi di scheletro e terra fine, con buon drenaggio. La tecnica di maturazione del vino ha diversa­mente influenzato i prodotti ottenuti nei vari vigneti.

On a large farm in the Chianti Classico area, seven vineyards were studied. They had different levels of productivity despite similar cultural practices. The different vineyards were studied over a three-year period with regard to environmental and pedological aspects.
The parameters obtained have been correlated to phenological and productive trends, with regard to the sensorial analisys of wine and the color components. The wines were matured in oak barrel and steel tank to point out the best enological use of the different vineyards productions.
The results underline the phenotypical variability of Sangiovese, especialiy due to the physical structure of the examined soils. In particular, sugar accumulation depended on the soil characteristic, white acidity depended on the year. Under similar climate conditions, the best results on wine were obtained in sandy soils originating from sandy limestone rich with rock fragment. Maturation technique, using oak barrels or steel tanks, has differently influenced wines obtained from various soils.

Are all red wines equals regarding their vulnerability to Brettanomyces bruxellensis ?

Odours deemed harmful by the consumer and described as “stable”, “horse sweat” or “burnt plastic” can be found in wines. The responsible molecules are volatile phenols, produced by a spoilage yeast: brettanomyces bruxellensis. This species is particularly well adapted to the wine environment and can resists many stresses such as a high alcohol level, a low ph or high levels of SO2, more or less efficiently depending on the strain considered.

Impact of the maturity and the duration of maceration on phenolic composition and sensorial quality of Divico wines

Following its approval in 2013 by Agroscope, Divico became the first interspecific grape variety in Switzerland with high resistance to downy mildew (Plasmopara viticola) and grey rot (Botrytis cinerea), and medium resistance to powdery mildew (Uncinula nectator). Extremely riche in color, Divico grapes showed great enological potential to different styles of wine. Quickly, many wine growers were interested in planting this promising variety. Many of its potential are to be explored in the coming years.

Chemical and sensory profile of Brazilian red wines upon the cultivar and geographic origin of vineyards

Identifying best parameters to characterize genotypes capability of retaining adequate malic acid at harvest and in final wines

Under current climate change pressures, obtaining grapes with adequate acidity at harvest is one of the main challenges for growers, especially if the goal is producing sparkling wines. This issue arises from two main occurrences: i) higher temperatures enhance degradation of malic acid; ii) grape maturity may occur under suboptimal climatic conditions due to an advanced phenology.
