Impact of organic inputs on soil biodiversity in vineyard systems. A monitoring approach during 20 years

Abstract

Conventional vineyard practices have lead in many environmental disturbances as erosion, soil compaction, loss of organic matter and soil biodiversity, water contamination… Therefore, there is an increasing interest to develop sustainable viticulture in the famous Champagne vineyard for 20 years: a program called “VITI 2000” has been developed since 1986 by CIVC (Inter-professional Committee of Champagne Wine) in collaboration with scientists. The aims are i) to assess the impact of viticultural practices on soil functioning, environmental properties and wine quality, ii) to advice progressively sustainable practices to winegrowers. One strength of this program is to allow a long term field experiment: earthworm communities, microbial biomass, soil and vine parameters were followed during 25 years in 19 plots representing 66 treatments to test the impact of pesticides applications (nematicides, fungicides, herbicides), or organic matter inputs, or vine management (organic vs conventional vs integrated). This program ended in a huge data collection e.g. the data table of earthworm communities (species, body mass, sexual stage) presents more than 39 000 lines. A database, compatible to others soil fauna databases developed by the laboratory EcoBio (University Rennes 1), has been developed. First results indicate that i) grass strip between the vine rows and compost quickly stimulate biological soil processes, while dried organic matter inputs have a slow positive impact, ii) fungicides containing copper alter in the same pattern earthworms and microorganisms, iii) integrated management could be as positive as organic practices. Statistical treatments are still going on and further results will be discussed.

Evaluating South African Chenin blanc wine styles using an LC-MS screening method

Sorting Chenin blanc is one of the most important white wine cultivars in South Africa. It has received a lot of attention and accolades in the past years and more research than ever is dedicated to this versatile cultivar. According to the Chenin blanc association of South Africa, there are three recognized dry wine styles, Fresh and Fruity (FF), Rich and Ripe Unwooded
(RRU), and Rich and Ripe Wooded (RRW). They are traditionally established with the aid of expert sensory evaluation, but the cost and the (subjective) human factor are aspects to be taken into account. A more objective and possibly robust way of assessing and attributing these styles can be the use of chemical analysis.

New markers for monitoring “fresh mushroom aroma” in wine: A dual approach using microbiological and chemical tools from the vineyard to winery–A synthesis of recent research advances

The ‘fresh mushroom off-flavour’ has been recognized by the wine industry as an emerging defect since the 2000s. For many years, this off-flavour was not specifically characterized and rather grouped under ‘earthy’ and ‘musty’ taints. However, it has become increasingly problematic due to its rising prevalence. In some vineyards, incidents of this off-flavour now occur as frequently as once every five years. This trend may be associated with climatic changes affecting regions that are more prone to warm and wet seasons.

High density balsamic vinegar: application of stable isotope ratio analysis to determine watering down.

Aceto balsamico di Modena IGP (ABM) is an Italian worldwide appreciated PGI (Protected Geographical Indication) vinegar,  obtained from cooked and/or concentrated grape must (at least 20% of the volume), with the addition of at least 10% of wine vinegar and a maximum 2% of caramel for color stability (EU Reg. 583/ 2009).
