Impact of organic inputs on soil biodiversity in vineyard systems. A monitoring approach during 20 years

This presentation aims to demonstrate that the value attributed to wine as we today know it is based on three factors: 1) sensory balance, 2) personality, and 3) bioactivity.

As greenhouse gas emissions continue to rise, climate projections indicate an increased likelihood of heat waves and drier conditions in canada. these changes pose significant challenges to grapevine cultivation, particularly during critical growth stages such as new plantings. interspecific hybrid grape varieties, developed through different breeding programs that combine vitis vinifera with more robust species like v. riparia and v. labrusca varieties, are often touted for their potential resilience to environmental stress.

Considering That Innovation Supports A Company’s Competitive Advantage And Drive Higher Profits (Dogru A. & Peyrette J., 2022), A Key Challenge Of Wine Companies Is Getting Practitioners To Understand That Innovation-Related Wine Research Increases The Likelihood Of Competitive Advantage, Bringing Financial Success. A Continued And Enhanced Investment In Research Is, Thus, A Prerequisite For Commercial Success In Today’s Globalized And Competitive Wine Industry (Høj P., Pretorius I.S., & Day R., 2003).

According to the Protected Designation of Origin (PDO), Cava is protected in the quality sparkling wines made by the traditional Champenoise method were the wine realize a second fermentation inside the own bottle1. Geographical and human peculiarities of each bottle are the main way for the final quality2. The aim of this study is to find correlations and which target compounds are the most representative of the quality of two different grape varieties, Pinot Noir and Xarel·lo. The quality of these two types of grapes is being studied for each variety by a previous classification of the vineyard made by the company who provided the samples (qualities A,B,C,D, being A the better one and D the worst one). The target compounds studied are organic acids and polyphenols. The methodology for the determination of organic acids is HPLC-UV/vis and for some of them the enzymatic methodology.

Glutathione is a tripeptide that is mainly found in reduced form in grapes. It generates during the maturation of the grape, increasing significantly after veraison [1].
