Studio dell’ambiente viticolo attraverso la parametrazione (punto di incrocio) delle curve di maturazione delle uve (pinot nero, oltrepo’ pavese pv italia settentrionale – 45° parallelo Nord)

Abstract

Sono stati presi in considerazione alcuni dati agrometeorologici dell’Oltrepò Pavese (temperature e piovosità degli ultimi 80 anni) e gli studi delle curve di maturazione condotti in zona sul Pinot nero da spumante negli anni (1988-1991, 1999-2000, 2006-2008), si nota che l’aumento progressivo negli anni delle temperature attive (indice di Winkler) ha determinato un anticipo dell’invaiatura, definita dal parametro “punto di incrocio” (intersezione delle funzioni di zuccheri ed acidità nel tempo), con conseguente anticipo della data di vendemmia di circa 12-15 gg.

English version: Some climate data of Oltrepò Pavese D.O.C. zone – 45° of latitude north, north-west Italy – (mainly temperature and rainfall of the last 80 years) and some studies of Pinot noir ripening are considered. An increase of the temperature (Winkler index, °C) has been recorded mainly in the last twenty years. According with this the date of the full veraison, pointed with the method of the cross point between the lines of sugar (°Brix) and total acidity (g/L), results anticipated of 15 days with vintage advance of about 12- 15 days.

Distinguishing of red wines from Northwest China by colour-flavour related physico-chemical indexes

Aim: Northwest China occupies an important position in China’s wine regions due to its superior geographical conditions with dry climate and sufficient sunlight. In this work, we aimed to investigate the physico-chemical colour and flavour characteristics of red wine in Northwest China.

Market entry strategies in the U.S. alcohol distribution: The case of French wine exporters

This study examines the different strategies adopted by wine exporters located in France for penetrating international alcohol distribution networks in the U.S. market (and to a lesser extent the Canadian market). Grounded in the Business-to-Business (B2B) marketing literature (Ellegaard and Medlin, 2018), this study adopts a framework integrating a ‘Stakeholder’ approach for understanding the logics behind exporters’ strategies to penetrate the alcohol distribution networks (wholesalers, importers, alcohol monopolies).

INFLUENCE OF THE THICKNESS OF OAK ALTERNATIVES ON THE COMPOSITION AND QUALITY OF RED WINES

Aging red wines in oak barrels is an expensive and laborious process that can only be applied to wines with a certain added value. For this reason, the use of oak alternatives coupled with micro-oxygenation has progressively increased over recent years, because it can reproduce the processes taking place in the barrels more economically and quickly [1]. Several studies have explored how oak alternatives [2-5] can contribute to wine composition and quality but little is known about the influence of their thickness.

Transcriptomic analyses of wild Vitis species under drought conditions for next-generation breeding of grapevine rootstocks

Drought is one of the main challenges for viticulture in the context of climate change. Selecting drought-tolerant plant material can be an effective strategy for a sustainable viticulture.
