Caractérisation du terroir en Espagne : méthodologie de l’évaluation et de la validation

Abstract

In recent years, there has been a growing interest in characterizing the ecological environment of vineyard production, and the growing need to delimit and characterize with precision the different homogeneous viticultural units. This has allowed the development of new studies which have as their objective the Vineyard Zoning. The delimitation and characterization of wine-growing areas poses specific problems in Spain, not only linked to the specific characteristics of the territory, but also to the size, distribution and index of viticultural occupation in the designations of origin.

In this work we try to describe the methodology that has been applied to the Denomination of Origin Ribera del Duero (325,000 Ha and 12,000 Ha of vineyard) and to the Qualified DO Rioja (300,000 Ha and 50,000 Ha of vineyard) with the objective of systematically and analytically defining homogeneous units, in which the viticultural vocation can be expressed quantitatively with the resulting comparative discussions (Sotés and Gómez-Miguel, 1994, 1997).

Eliminating Brettanomyces and lactic acid bacteria in wine: the potential of Ultra-High Pressure Homogenization (UHPH)

Ultra-High Pressure Homogenization (UHPH) is an innovative technology that can be seamlessly integrated at various stages of winemaking. Its application helps minimize or even eliminate the need for sulphites and other antimicrobial or antioxidant treatments, offering a faster and more sustainable alternative.

Non-saccharomyces yeasts in the biocontrol of grape molds in vineyards to reduce the use of pesticides

The wide diffusion of organic cultivation of vineyards and the need to reduce the use of pesticides highlights the urgent need for alternative and sustainable methods of vine protection by pathogen molds.

CHARACTERIZATION OF ENOLOGICAL OAK TANNIN EXTRACTS BY MULTI-ANALYTICAL METHODS APPROACH

Oak tannin extracts are commonly used to improve wine properties. The main polyphenols found in oak wood extracts are ellagitannins¹ that release ellagic acid upon hydrolysis and comprise numerous structures². Moreover, oak tannin extracts contain other compounds giving a complex mixture. Consequently, the official OIV method based on gravimetric analysis of the tannin fraction adsorbed on polyvinylpolypyrrolidone is not sufficient to describe their composition and highlight their chemical diversity.

Application of nitrogen forms such as nitrate, urea, and amino acids effects on leaf and berry physiology and wine quality

Nitrogen (N) uptake by grapevine roots in forms like nitrate, ammonium, urea, or amino acids influences vegetative and generative growth, impacting grape quality and wine sensory profile. The study examined nitrogen’s influence on phenolic compounds in leaves, berries, and wine across different scales — hydroponics, soil culture, and vineyard trials. Nitrogen forms altered metabolite patterns in leaves and wine significantly, affecting aroma and flavor. Key nitrogen assimilation enzymes (NR, NiR, GS) in grapevine rootstocks responded to nitrogen forms and timing. Hydroponically grown rootstocks fertilized with various forms showed differences in enzyme expression and activity, suggesting rootstocks can assimilate amino acid glutamine (Gln).
