Zonazione dell’area viticola doc durello

Abstract

[English version below]

Il lavoro di zonazione riveste un ruolo importante per capire le potenzialità e la vocazionalità di una specifica area viticola. La viticoltura dovrebbe essere vista in funzione dell’obiettivo enologico che si vuole realizzare e quindi particolare importanza riveste il risultato delle vinificazioni delle uve provenienti dai vigneti delle diverse aree della zona di produzione oggetto d’indagine. La zonazione dell’area a DOC Monti Lessini Durello ha preso in esame la varietà “Durella”, vitigno autoctono del territorio, che rappresenta la maggior parte della produzione vitivinicola della zona. Durante il quadriennio 2002-2005 si sono effettuati i rilievi vegeto-produttivi e le vinificazioni delle uve di questa varietà provenienti dalle 15 aree individuate attraverso un’indagine podologica del territorio di coltivazione Monti Lessini Durello, che si estende su un’ampia superficie nelle province di Verona e Vicenza. Un aspetto innovativo di questo lavoro e di aver introdotto, sebbene solo per un’annata, la valutazione del potenziale enologico del vino anche attraverso il processo di spumantizzazione con il metodo classico. In questo modo si è potuto poi verificare, attraverso l’analisi sensoriale, non solo le peculiarità delle diverse zone ma anche la loro attitudine al processo di spumantizzazione, confrontando la valutazione dei vini fermi con quelli spumante di ogni singola area vocazionale. Tale analisi ha evidenziato al di là delle diverse caratteristiche di ogni singola area l’attitudine di questo vitigno a dare origine a vini spumanti di elevata qualità.

The task of zoning plays a significant role in understanding the potential and suitability of a specific vine-growing area. Viticulture should always be considered in the light of the oenological objectives that one has in mind and the results of the vinification of grapes from different areas within the production zone under consideration are therefore of particular importance. The zoning of the Monti Lessini Durello D.O.C. area focused on the indigenous “Durella” variety, which is responsible for the majority of the zone’s viti-vinicultural production. During the four-year period of 2002-2005 we carried out surveys regarding vegetative and fruit yields, as well as vinifying grapes of this variety from the 15 areas we identified as a result of a pedological study of the region for the cultivation of Monti Lessini Durello, which covers quite a large area in the Provinces of Verona and Vicenza. An innovative aspect of this work was that – if only for one vintage – we also introduced an evaluation of the various wines’ oenological potential by subjecting them to prise de mousse. In this way, we were able to test, by means of sensory analysis, not only the peculiarities of the different zones but also their appropriateness for producing sparkling wines, comparing our evaluation of the still wine and the sparkling one from each specific production area. This analysis highlighted – apart from the different characteristics of each individual area – this variety’s aptitude for producing sparkling wines of very high quality.

Juice carbon isotope discrimination is related to vine growth and fruit quality of Barossa Shiraz

Aim: Interactions between soil, climate and management that modulate vine growth, yield and grape composition are strongly defined by vine water availability and nutrient uptake during the season. Carbon isotope discrimination (δ13C) has been used as an integrative measurement of vine water availability during the season, with the potential to identify spatial variations of terroir in

Adsorption capacity of phenolics compounds by polyaniline materials in model solution

The aim of this work was to study the trapping capacity of four polyaniline polymers towards phenolic compounds in wine-like model solutions. METHODS: The model wine solution was composed of 12% (v/v) and 4 g/L of tartaric acid adjusted to pH = 3.6. A series of centrifuge tubes (15 mL) were filled with 10 mL of model solution enriched with 50 mg/L of five phenolic compounds (i.e., Gallic acid, caffeic acid, (+)-catechin, (-)-epicatechin, and rutin), and treated with different doses of PANI polymer (i.e., 0, 2, 4 and 8 g/L). After the addition of the polymer, the samples were stirred using a platform shaker at room temperature (20 ºC) for 2, 8, 16 and 24 h. All treatments included three replications.

Impact and comprehension of nitrogen and lipid nutrition on the production of fermentative aromas with different S. Cerevisiae yeasts used for spirits

In the Cognac appellation, the production of white wines is almost exclusively dedicated to elaborate Charentaise eaux-de-vie. In this sense, the quality of Cognac eaux-de-vie intrinsically depends on the quality of the base wines subjected to the distillation stage. In this context, the production of these base wines differs from those of classic white wines to release particular organoleptic properties during the distillation stage.
