Spatial characterisation of terrain units in the Bottelaryberg-Simonsberg-Helderberg wine growing area (South Africa)

Abstract

The first South African wine was made by Jan van Riebeeck on the second of February 1659. His initial determination to produce wine at the Cape refreshment station was continued by other governors resulting in improvement and expansion of the embryo industry. As the colony opened up and new areas were discovered, so the wine industry developed to its present extent of over 100 000 ha (SAWIS, 1999). The initial expansion was based on ease of access and mainly focussed on fertile valleys, with rivers to provide irrigation in the more arid regions. Yield was often the overriding factor considered. However, when over-production became a problem in the early twentieth century, the focus was moved to quality. This eventually resulted in the introduction of the Wine of Origin legislation in 1973. South Africa is, therefore, a relatively young wine-producing country and has little tradition or experimental data to support delimitation of areas of origin. Such areas are demarcated on application by the producers. Natural factors, such as landscape, soil and macroclimatic patterns are used to determine boundaries, after which these demarcated areas are allowed to develop to express their specific wine style and character instead of proving their originality beforehand (Saayman, 1998). The identification and spatial characterisation of terrain units will act, therefore, as a scientific basis for the delimitation of areas for the production of characteristic wines of high quality. It will also provide an important basis for future development and management decisions and enable South Africa to remain competitive in an ever-expanding international wine market.

In recent years, heightened awareness of the environmental impact has led to sustainability as a key issue for the winemaking sector.

Toasted Vine-Shoots As An Alternative Enological Tool. Impact On The Sensory Profile Of Tempranillo Wines

The use of toasted vine-shoots as an alternative enological tool to make differentiated wines has generated interest among researchers and wineries. However, the evolution of these wines in bottle and the effect on the sensory profile has not been studied so far.

Response of red grape varieties irrigated during the summer to water availability at the end of winter in four Spanish wine-growing regions: berry phenolic composition

Water availability is the most limiting factor for vineyard productivity under Mediterranean conditions. Due to the effects caused by the current climate change, wine-growing regions may face serious soil moisture conservation problems, due to the lower water retention capacity of the soil and higher soil irradiation. The aim of this work was to evaluate the effects of soil recharge irrigation in pre-sprouting and summer irrigation every week (30 % ETo) from the pea size state until the end of ripening (RP) compared to exclusively summer irrigation every week (R) in the same way that RP, on berry phenolic composition at harvest.

Effects of soil characteristics on manganese transfer from soil to vine and wine

Aim: In recent times the export of Beaujolais wines has been jeopardised due to a limit of manganese content (Mn) in wine implemented by China (2 mg/L), related to suspicions of potassium permanganate fraud. Nevertheless, soil Mn content may be high in some soil types in Beaujolais. The aim of this study was to improve knowledge of manganese transfer from soil to vine and wine because data on this subject is scarce.

Les effets du terroir ou l’expression des potentiels à valoriser

Research into the effects of the Terroir is of major interest for the wine sector. The study of Terroir-Vine-Grape relations, even if it is complex, is fundamental for all viticulture: indeed, the quality of the grape must be the result of the most reasoned agro-viticultural management of the vine possible, which must first, to respect a production balance. The goal sought by the winegrower is to obtain a wine, the optimized result of the interactions Terroir-Grape variety. This link to the terroir is therefore essential to establish by taking into account on the one hand the behavior of the vine (which is the cause), and on the other hand, its effects on the grapes and finally on the wine.
