The role of climate/soil of different zones/terroirs on grape characteristics

Abstract

According to the different concern of the ‘traditional’ and the ‘new’ wine-producing Countries, a variable importance is recognized to the climate/soil and to grapevine cultivars as factors affecting the wine quality. However, the viticultural experience can state that, within each area, climate and soil plays an incontestable role in affecting grape quality, and consequently wine quality, as well as the genetic characteristics of the cultivar.
Zoning different areas is an interesting tool to study and characterize the ecological, geological, ecophysiological and biological factors which interact with the grapevine to determine the wine quality and that can be summarized by the French word ‘terroir’. The aim is to delimit and individuate homogeneous territories that can give homogeneous, identifiable, corresponding, enological products.
Actually, different approaches may be pursued in the ‘zoning studies’: historical, bioclimatic, pedological, varietal or multi-disciplinary. Many experiences in zoning viticultural areas have been done, particularly in the traditional viticultural areas, such as the DOC and DOCG areas in Europe (in particular France and Italy). Different soil types, and microclimatic zones, may influence with the presence of grape phenol precursors, and then the wine structure and aroma. Some examples illustrate the variety-ambient interaction as the basic binomial for grape quality as well as for wines characterized by specific and identifiable attributes.

Study and valorization of vineyards “terroirs” of A.O.C. Cahors (Lot, France)

In the current context of market competition and consumption evolution, it is necessary to produce wines of a genuine typicity. The Terroir represents an unique and irreproducible inheritance that can be valorized through the origin and the sensory characteristics of the wines.

Zonazione aziendale nel territorio del Chianti classico e valorizzazione dei vini

Nell’ambiente del Chianti Classico è stato applicato un progetto di zonazione aziendale con l’objettivo di valorizzare le produzioni dei diversi vigneti. In particolare sono stati individuati sette siti, sottoposti a studio particolareggiato per un triennio.

Making sense of a sense of place: precision viticulture approaches to the analysis of terroir at different scales

Agriculture, natural resource management and the production and sale of products such as wine are increasingly data-driven activities. Thus, the use of remote and proximal crop and soil sensors to aid management decisions is becoming commonplace and ‘Agtech’ is proliferating commercially; mapping, underpinned by geographical information systems and complex methods of spatial analysis, is widely used…

The impact of delayed grapevine budbreak on lemberger wine sensory compounds under variable weather conditions

Spring freeze events threaten grape production globally. As grape buds emerge from dormancy in spring, freezing temperatures have the potential to damage green tissues, decreasing yield potential and compromising fruit quality by harvest.

The characterization of Vitis vinifera L cv. Cabernet sauvignon: the contribution of Ecklonia maxima seaweed extract

Biostimulants and biofertilizers are considered environmentally friendly and cost-effective alternatives to synthetic fertilizers, plant growth regulators and crop improvement products. Broadly, plant biostimulants are expected to improve nutrient use efficiency, tolerance to abiotic stress, quality traits and availability of nutrients in the soil or rhizosphere. Currently, seaweed extracts account for more than 33% of the total plant biostimulant market. Within this category, Ascophyllum nodosum (AN), is the most widely studied and applied in biostimulant formulations.
