Methodological approach to zoning

Abstract

An appellation or geographic indication should be based on the terroir concept in order to ensure its integrity. The delimitation of viticultural terroirs must include two consecutive or parallel steps, namely (a) the characterisation of the environment and identification of homogenous environmental units (basic terroir units, natural terroir units) taking all natural factors into account, as well as (b) the characterisation of the viticultural and oenological potential of these units over time.

La délimitation des terroirs viticoles doit inclure deux étapes consécutives ou parallèles, en l’occurrence (a) la caractérisation de l’environnement et l’identification d’unités environnementales homogènes (unités terroir de base, unités terroir naturels) prenant en compte tout facteurs naturels, ainsi que (b) la caractérisation du potentiel vitivinicole de ces unités à travers le temps.

Can different green manure fertilizations affect the vine balance and grape quality? First evidence of multi-year study

In the context of sustainable viticulture that implements organic practices to maintain soil fertility, green manuring plays a crucial role due to its ability to stock carbon and nitrogen in soil while supporting biodiversity.

New biological tools to control and secure malolactic fermentation in high pH wines

Originally, the role of the malolactic fermentation (MLF) was simply to improve the microbial stability of wine via biological deacidification. However, there is an accumulation of evidence to support the fact that lactic acid bacteria (LAB) also contribute positively to the taste and aroma of wine. Many different LAB enter into grape juice and wine from the surface of grape berries, cluster stems, vine leaves, soil and winery equipment. Due to the highly selective environment of juices and wine, only a few types of LAB are able to grow.

Release and perception of γ-nonalactone and massoia lactone in the red wine matrix: impact of ethanol and acidity

Climate change (CC) is altering grape/wine composition, leading to challenges in maintaining wine sensory quality.

Ochratoxin a degradation by Botrytis cinerea laccase: effect of oenological factors and redox mediators

This study evaluates the effect of different oenological factors and natural mediators on the degradation of Ochratoxin A (OTA) using Botrytis cinerea laccase.

The informative potential of remote and proximal sensing application on vertical- and overhead-trained vineyards in Northeast Italy

The application of remote and proximal sensing in viticulture have been demonstrated as a fast and efficient method to monitor vegetative and physiological parameters of grapevines. The collection of these parameters could be highly valuable to derive information on associated yield and quality traits in the vineyard. However, to leverage the informative potential of the sensing systems, a series of preliminary evaluations should be carried out to standardize working protocols for the specific features of a winegrowing area (e.g., pedoclimate, topography, cultivar, training system). This work aims at evaluating remote and proximal sensing systems for their performance and suitability to provide information on the vegetative, physiological, yield and qualitative aspects of vines and grapes as a function of different training systems in the Valpolicella wine region (Verona, Italy).
