Investigation on harvesting period choices for correct interpretation of experimental results

Abstract

Happens too often in scientific papers to find the same harvesting period of a cultivar, although the used treatment influence a maturity curve of investigated thesis.
This inevitably leads to wrong conclusions when comparing the treatment effects, since obtained on maturity stages more or less far from those technologically correct.
The present paper has the aim to enhance the sensibility of our environment, and not only, this fundamental aspect in the framework of a larger project, has the aim to enhance various aspects of “quality” (for example organoleptic, economic, social and existential) and of its “economies” (Cargnello G. (1996): La qualite economique, l’economie de la qualite et la qualite economique des preferences: differentes considerations. Compte-rendu n° 9 GESCO, Budapest (Hongrie), 21 -23 Août, pp.379-384.). It was conducted on cv. Prosecco in “Terra della Valle del Piave” in collaboration with respected Casa vitivinicola Carpenè – Malvolti di Conegliano.
Particularly, the research about short cut (Spur Pruned Cordon of Conegliano) and long (precisely of training form “Prosecco Alta Marca”), showed that production of the last one is penalised if harvesting time is judged on thesis of Pruned Cordon, and inversely, in function of product typology we want to obtain and of enterprise objectives we want to achieve.

Sensory and chemical effects of postharvest grape cooling on wine quality

Wine cellars are affected by seasonally fluctuating workloads and face challenges especially in the harvest period connected to the required timely processing of the harvested grapes.

EVALUATING WINEMAKING APPLICATIONS OF ULTRAFILTRATION TECHNOLOGY

Ultrafiltration is a process that fractionates mixtures using semipermeable membranes, primarily on the basis of molecular weight. Depending on the nominal molecular weight cut-off (MWCO) specifications of the membrane, smaller molecules pass through the membrane into the ‘permeate’, while larger molecules are retained and concentrated in the ‘retentate’. This study investigated applications of ultrafiltration technology for enhanced wine quality and profitability. The key objective was to establish to what extent ultrafiltration could be used to manage phenolic compounds (associated with astringency or bitterness) and proteins (associated with haze formation) in white wine.

Effect of pre-fermentative addition of oenological tannins on the volatile composition and colour characteristics of white wines

This study investigates the effect of pre-fermentative addition of oenological tannins on basic physicochemical parameters, total polyphenols index (TPI), antioxidant activity (DPPH method), colour traits, and volatile organic compounds (VOCs) of white wines made from ‘Vermentino’ or ‘Erbaluce’ grapes (Vitis vinifera).

Contribution of soil and atmospheric conditions to leaf water potential in grapevines

Etant lié au sol et aux conditions atmosphériques, le statut hydrique influence la physiologie de la vigne d’une part, mais joue aussi un role important en ce qui concerne la qualité du raisin et donc du vin d’autre part. Nous avons mesuré, dans la région de Stellenbosch, le statut hydrique sur des pieds de Sauvignon Blanc non irrigués, implantés sur 2 terroirs différents, l’un froid, l’autre plus chaud.

The« Sigales’ method »

Le comportement de la vigne est étroitement lié aux propriétés hydriques des sols surtout dans leurs parties profondes.
