Progetto di zonazione delle valli di Cembra e dell’Adige. Analisi del comportamento della varietà Pinot nero in ambiente subalpino

Abstract

[English version below]

Nel 1990 la Cantina LA VIS ha intrapreso un progetto di zonazione dei terreni vitati allo scopo di acquisire le conoscenze scientifiche atte a consentire il miglioramento delle qualità dei prodotti. Tale progetto si è articolato su di una superficie di 2000 ettari ubicati lungo l’asta fluviale del fiume Adige da Trento a Salorno e del torrente Avisio da Lavis a Segonzano. Data la vastità dell ‘area indagata si è suddivisa la stessa nelle zone di Cembra, Lavis, Meano e Salorno.
Nell ‘ambito di tale progetto è stata posta particolare attenzione al comportamento della varietà Pinot nero, sia sotto gli aspetti vegeto-produttivi che su risultati ottenuti a seguito di prove di microvinificazione.
I parametri vegeto-produttivi presi in considerazione (valori medi quadriennali 1992-1995) hanno evidenziato come nelle quattro zone oggetto d’indagine la produzione non ha manifestato differenze statisticamente significative nei vari ambienti, anche se alcuni dei parametri influenzanti la resa presentano delle differenze fra loro, come ad esempio il peso medio del grappolo che a Cembra présenta i valori più bassi. Analizzando i parametri qualitativi, si evidenzia come a Cembra, conseguenza di una maggiore quota altimetrica, si ha un basso grado zuccherino, una più alta acidità totale e un minor pH. L’analisi organolettica dei vini ottenuti e la successiva elaborazione statistica ha evidenziato come nelle due annate d’indagine (1992-1993) nella zona di Cembra, si sono ottenuti vini con note di tipicità e gusto superiore alla média e si è potuto evidenziare come nell ‘unità pedologica CE2 di tale zona si sono avute sensazioni gustative ed aromatiche superiori alla media.
In 1990 Cantina LA VIS undertook a zonation project of the vine terrains for the purpose of acquiring scientific knowledge to improve product quality. This project was centered on an area of 2000 hectares along the banks of the Adige river from Trento to Salorno and the Avisio stream from Lavis to Segonzano. Due to its vast size the area under examination was divided into four zones: Cembra, Lavis, Meano and Salorno.
The project examined in particular the Pinot Nero variety, the vegetal-fertile aspects as well as the results of microvinification tests.
The vegetal-fertile parameters taken into consideration (averages values from 1992-1995) show that in the four areas production did not differ significantly under the various environments, even if some parameters affecting the yield do differ, as for example in Cembra the mean weight of the grape bunch was lower. By analyzing the qualitative parameters it was found that in Cembra, with a higher altitude, there was a lover sugar level, higher total acidity and a lower ph. Analysis of the organoleptic characteristics of the wines obtained and the successive statistical elaboration has shown that the two harvests in Cembra produced wines with a more superior flavor and typicality and pedologie unit CE2 of this area a higher than average flavor and aroma were evident.

The importance of soil and geology in tasting terroir; a case history from the Willamette valley, Oregon

Wines differ from each other based on seven different factors: the type of grape; the bedrock geology and resulting soils; the climate; the soil hydrology; physiography of the site; the winemaker and the vineyard management techniques. The first five of these factors make up what the French call terroir, “the taste of the place”.

Metabolomics screening of Vitis sp. interspecific hybrids to select natural ingredients with cosmetic purposes

Introducing natural ingredients using green chemistry practices is a major challenge in cosmetics industry to follow the market trend. Among the plants of cosmetic interest, vine products show a remarkable diversity of natural substances with high potential for the cosmetic and dermatological sectors. To date, research focuses on well-known compounds like E-resveratrol and E-ε-viniferin,

Influence of agrophotovoltaic on vine and must in a cool climate

The current energy crisis means that interest in agrophotovoltaics has increased significantly. The reason behind this is that the system aims to combine agricultural production with energy production. During the three-year period from 2020 to 2022, the effects of photovoltaic panels on the vine, the yield and the quality of the must were studied in Walenstadt in northern Switzerland, an area with a cool, humid climate. 65 Pinot noir vines were planted in the 160m2 study area. Because of the large edge effects, only 3 repetitions with 4 vines each could be created. A significantly lower leaf infestation by Plasmopara viticola was observed among the panels in each of the three years.

OPTIMISATION OF THE AROMATIC PROFILE OF UGNI BLANC WINE DISTILLATE THROUGH THE CONTROL OF ALCOHOLIC FERMENTATION

The online monitoring of fermentative aromas provides a better understanding of the effect of temperature on the synthesis and the loss of these molecules. During fermentation, gas and liquid phase concentrations as well as losses and total productions of volatile compounds can be followed with an unprecedented acquisition frequency of about one measurement per hour. Access to instantaneous production rates and total production balances for the various volatile compounds makes it possible to distinguish the impact of temperature on yeast production (biological effect) from the loss of aromatic molecules due to a physical effect³.

Optimisation de la fertilisation du Cot sur le Causse de l’Appellation d’Origine Contrôlée Cahors

The Appellation d’Origine Contrôlée area of ​​Cahors (Lot) covers an area of ​​21,700 ha, spread over 45 municipalities, of which only 4,300 are planted with vines. The main grape variety of this AOC is the Cot noir which represents 70% of the grape varieties, thus giving their typicality to the wines of this region; but despite this importance, to our knowledge, its physiology has remained relatively unstudied.
