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.

Les outils pour favoriser le renouvellement des générations en viticulture

French lawmakers have chosen the family-type winegrowing business as the benchmark for drafting the legal framework for winegrowing businesses and winegrowers. In france (source: msa), in 2022, there were 1,444 new winegrowers, an increase of 3% compared with 2021, representing 10% of new farm managers. The retention rate for winegrowers is 75% (up 13% on 2021), compared with 77% for all agricultural sectors (stable).

Performance of Selected Uruguayan Native Yeasts for Tannat Wine Production at Pilot Scale

The wine industry is increasing the demand for indigenous yeasts adapted to the terroir to produce unique wines that reflect the distinctive characteristics of each region. In our group, we have identified and characterized 60 native yeast strains isolated from a vineyard in Maldonado-Uruguay, in which three strains stood out: Saccharomyces cerevisiae T193FS, Saturnispora diversa T191FS, and Starmerella bacillaris T193MS. Their oenological potential was evaluated at a semi-pilot scale in Tannat must vinification in the wine cellar to have a more precise and representative evaluation of the final product.

Geospatial technologies in spatially defined viticulture: case study of a vineyard with Agiorgitiko variety in Koutsi, Nemea, Greece

Geospatial technologies have significant contribution to viticulture, especially in small-scale vineyards, which require precise management. Geospatial data collected by modern technologies, such as Unmanned Aerial Vehicle (UAV) and satellite imagery, can be processed by modern software and easily be stored and transferred to GIS environments, highlighting important information about the health of vine plants, the yield of grapes and the wine, especially in wine-making varieties. The identification of field variability is very important, particularly for the production of high quality wine. Modern geospatial data management technologies are used to achieve an easy and effortless localization of the fields’ variability.

Interaction among grapevine cultivars (Sangiovese, Cabernet-Sauvignon and Merlot) and site of cultivation in Bolgheri (Tuscany)

Different “landscape unit” have been identified in Bolgheri area (a viticultural appellation in the Tirrenian coast of Tuscany) by the aid of pedological, landscape and agronomic observations in the 1992-1993 period. In all cultivar (Sangiovese, Cabernet Sauvignon and Merlot) x landscape unit combinations, experimental plots were chosen in homogeneous vineyards, single cordon trained (about 3300-4500 vines/hectare). Grape maturation was studied by weekly samples of berries from veraison to vintage in the 1992-1995 period. At harvest yield and must composition traits were measured and, from the most représentative plots, sixty kilograms of grapes were harvested each year and vinified according to a standardised scheme. Wines were evaluated by standard chemical and sensory analyses.
