Observatoire du Grenache en Vallée du Rhône: incidence du terroir sur la diversité analytique et sensorielle des vins

Abstract

Rhone Valley A.O.C. Vineyards cover more than 70 000 hectares, of wich more than 40 000 plantedwith Grenache N. The Grenache observatory was created in 1995. The object of this 24 parcels network covering main Rhone Valley soils is to state the effect of terroir on plant physiology and wine characteristics. The results show a very important diversity in Grenache behaviour, but a good stability of the differences for the three studied vintages. This allows to characterize different types of grapes which vinified in the same conditions give very different wines. Main discrepancies affect the acidic and phenolic content of grapes and wines. They are confirmed by sensorial analysis wich gives a good description of gustative and aromatic characteristics of wines coming from the different parcels.

Struck flint aroma in Chardonnay wines: what causes it and how much is too much?

Struck flint/struck match/gun smoke/mineral aroma is considered desirable in some styles of wines, with this character sometimes evident in wines such as Burgundian Chablis and cooler climate barrel-fermented Australian Chardonnay.

Evidence of successful wine business strategies: customer acquisition, value or retention?

This presentation illustrates a series of successful wine businesses, which have managed to counter the downward trend impacting the global industry. How these businesses have been successful is explained through the planning and execution of strategies that focused on a clear and consistent aim in attracting new consumers. These cases add weight to the ehrenbergian position that for a business to be successful it must target new customers as a priority over alternative options like increasing value or improving customer retention.

Evaluation of phenology, agronomic and oenological quality in minority wine varieties in Madrid as a strategy for adaptation to climate change

The main phenological stages (budburst, flowering, veraison, and ripeness) and the fruit composition of 34 Spanish minority varieties were studied to determine their cultivation potential and help winegrowers adapt their production systems to climate change conditions. In total, 4 control cultivars, and 30 minority varieties from central Spain were studied during a period of 3 campaigns, in the ampelographic collection “El Encín”, in Alcalá de Henares, Madrid. Agronomic and oenological characteristics such as yield, and total soluble solids concentration have been monitored.

Extraction of stilbenes from grape cane waste and their possible applications

Vine pruning residues constitute a significant fraction of vitivinicultural waste; in fact, depending on the variety and training system, they can reach 1-5 tons/ha/year.

Producer organisations at the service of the favourable chain of values to winegrowers and winemakers: the example of France

French law and European Union law recognise the existence of interprofessional organisations that bring together all the links in the wine industry.
