The developement of vineyard zonation and demarcation in South Africa

Abstract

[English version below]

L’histoire de viticulture de l’Afrique du Sud embrasse 340 ans, et a commencé, à la province du Cap, où les colonisateurs hollandais ont planté les premières vignes. L’arrivée des Huguenots français en 1688 a avancé, le développement. Les vins de Constantia deviennent renommés, et ainsi ils sont les premiers “vins d’origine” de l’Afrique du Sud. Pendant l’occupation britannique de la province du Cap en 1806, la viticulture a développé, davantage, dû à l’inaccessibilité, de l’Europe et ses vins pendant cette période. On a plant, la plupart des vignobles à la région côtière du sud-ouest, aux environs de la province du Cap, et aux vallées limitrophes. Ces régions sont toujours productrices principales de vin. Vers 1850, les exportations de vin étaient très limitées, dû à la détérioration de la qualité de vin. Ce fait a résulté du manque de contrôle d’origine et de qualité. L’industrie a reconnu ce problème, ce qui mène à la fondation d’un système de contrôle de Vin d’Origine en 1973. Des experts techniques font la démarcation des secteurs de vin, en employant quatre catégories. Ces sont: (1) Régions, (2) Districts, (3) Circonscriptions (‘Wards’), et (4) Domaines. Faute d’assez de traditions, d’expérience et des données expérimentales (contrasté avec les pays européens de viticulture), la philosophie sud-africaine de démarcation embrasse l’identification des unités de terrain naturel, en employant des données techniques qui sont disponibles.

The 340 year old history of viticulture in South Africa started with the first planting of vines by the Commander of the first Dutch settlers at the Cape. Further expansion was encouraged by succeeding Governors and also stimulated by the arrival of the French Huguenots in 1688. Constantia wines became internationally famous and thus were the first ‘wines of origin’ from South Africa. After the British occupation of the Cape in 1806, viticulture was further stimulated due to the inaccessibility of Europe and its wines to Britain at that stage. Vineyards were mainly established in the south-western coastal zone around the Cape and in adjacent Inland River valleys were irrigation water was available. These areas, characterized by a Mediterranean climate, are still the main wine producing regions today. Towards 1850, wine exports reached an ail time low because of the deterioration in wine quality, mainly as result of the absence of control over origin and quality. This problem was realized by the industry and resulted in a Wine of Origin Control system since 1973. Demarcation of existing vineyards was, and still is, done by technical experts, using four categories, viz. (1) Regions, based on broad geographical features and administrative boundaries; (2) Districts, based on geographical and macro climatic features; (3) Wards, essentially based on uniform soil, climatic and ecological patterns; and (4) Estates, based on the concept of singular ownership of vineyards and wine being produced on the estate. To demarcate Wards, land type maps are used. Land types are a concept unique to South Africa and are defined as a class of land over which the macro climate, the terrain form and soil pattern each displays a marked uniformity. Land types differ from each other in terms of macro climate, terrain form or soil pattern, or combinations of these natural factors. Lacking sufficient tradition, experience and experimental information, compared to the old word wine countries, the philosophy behind demarcation in South Africa is to identify natural terrain units, using available technical information, and then allowing such units to develop and demonstrate particular wine styles and character, rather than demanding proof of uniqueness before demarcation is done.

Biochemical responses of crimson seedless (Vitis vinifera) grapevines to altered micro climatic conditions and different water treatments in the Breede River Valley of South Africa

The South African Table grape industry has to expand to new markets with high quality niche products, but limited water availability threatens sustainable production. To overcome this challenge and to obtain high-quality products for the new markets, require constant technological advancement. Currently, limited available scientific information about growth balances and physiology and especially grape quality parameters, hinders technological advancement and thus efficient regulatory management of the morphological, chemical, and pathological status of table grapes, especially in response to abiotic factors.

Outside and inside grapevine roots: arbuscular mycorrhizal fungal communities in a ‘nebbiolo’ vineyard 

In field conditions, grapevine roots are colonized by arbuscular mycorrhizal fungi (AMF). Little is known about the species composition of AMF communities associated to grapevine.

Tutela legale delle denominazioni di origine nel mondo (con aspetti applicativi)

Uno degli aspetti più importanti nel commercio internazionale dei vini a denominazione è quello del riconoscimento dei diritti di esclusiva garantiti sui e dal territorio geografico d’o­rigine. Al fine di cautelarsi nei confronti della sempre più agguerrita concorrenza mondiale, è opportuno adottare adeguate protezioni ufficiali e legali delle denominazioni che possono derivare sia dalla “naturalità” del prodotto stesso che dalla “originalità” più particolare.

Impact of toasting on oak wood aroma: creation of an oak wood aroma wheel

The impact of toasting process to produce aroma from oak wood intrinsic composition is well documented. It is admitted that such complexity contribute to the wine quality after barrel ageing. Despite our knowledge on the molecular identification of aroma impact compounds of oak wood, little research have been carried out, on a sensory level, on the aroma diversity of toasted oak wood.

High-resolution climate modelling for the Cognac region under climate change

Climate change has varied effects across French vineyards, with marked regional differences in temperature shifts. Fine-scale studies highlight significant local climate variability, emphasizing the need for precise regional characterization to adapt vineyard management at the regional scale.
