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.

Identification of key-odorants in Sauternes Wines

The aim of the present work was to investigate Sauternes wines aromas. The flavor profiles of two wines (vintages 2002 and 2003) were investigated. Key-odorants have been determined by AEDA applied to Amberlite XAD-2 resin extracts. Various complementary techniques were used to identify the compounds (pHMB extraction, chemical synthesis of non-commercial standards, co-injections on two capillary columns, odor description at the sniffing port, GC-MS and GC-PFPD).

When organic chemistry contributes to the understanding of metabolism mechanisms

Many compounds of interest in wine are difficult to analyze since they are present in very small quantities or they are unstable. The need for reliable data led scientists to develop complex method in order to overcome the analytical difficulties and provide accurate quantitative data for grape or wine characterization.

Adapting the vineyard to climate change in warm climate regions with cultural practices

Since the 1980s global regime shift, grape growers have been steadily adapting to a changing climate. These adaptations have preserved the region-climate-cultivar rapports that have established the global trade of wine with lucrative economic benefits since the middle of 17th century. The advent of using fractions of crop and actual evapotranspiration replacement in vineyards with the use of supplemental irrigation has furthered the adaptation of wine grape cultivation. The shift in trellis systems, as well as pruning methods from positioned shoot systems to sprawling canopies, as well as adapting the bearing surface from head-trained, cane-pruned to cordon-trained, spur-pruned systems have also aided in the adaptation of grapevine to warmer temperatures. In warm climates, the use of shade cloth or over-head shade films not only have aided in arresting the damage of heat waves, but also identified opportunities to reduce the evapotranspiration from vineyards, reducing environmental footprint of vineyard. Our increase in knowledge on how best to understand the response of grapevine to climate change was aided with the identification of solar radiation exposure biomarker that is now used for phenotyping cultivars in their adaptability to harsh environments. Using fruit-based metrics such as sugar-flavonoid relationships were shown to be better indicators of losses in berry integrity associated with a warming climate, rather than solely focusing on region-climate-cultivar rapports. The resilience of wine grape was further enhanced by exploitation of rootstock × scion combinations that can resist untoward droughts and warm temperatures by making more resilient grapevine combinations. Our understanding of soil-plant-atmosphere continuum in the vineyard has increased within the last 50 years in such a manner that growers are able to use no-till systems with the aid of arbuscular mycorrhiza fungi inoculation with permanent cover cropping making the vineyard more resilient to droughts and heat waves. In premium wine grape regions viticulture has successfully adapted to a rapidly changing climate thus far, but berry based metrics are raising a concern that we may be approaching a tipping point.

Riesling aroma composition in light of changing global temperatures – delving into the effects of warmer nights on the volatile profile of riesling grapes

Climate is a key parameter when the modulation of berry and subsequent wine composition is considered. Recent decades have already seen an increase in global surface temperatures
