Irrigation and terroir: two opposite concepts? Point of view of international experts and french consumers

Abstract

At long term, qualitative irrigation seems to be the most systematic, if not the best, cultural practice for dealing with climate change and yield increases without decrease grape quality. Given this backdrop, the acceptance or irrigation within the frameworks of the terroir definition takes a central place. Consistently, the objective of this work is to evaluate this compatibility. Since irrigation is basically a social practice, it is important to understand it from a sociological point of view.

To meet this commitment, a qualitative questionnaire was implemented: standard personal interviews with no frequency (subject surveyed once) with a multi-topic research (omnibus research). 18 participants to the 19th GiESCO Meeting were selected as participants to the questionnaire. In a second instance, a quantitative questionnaire was evaluated: depth or intensive questionnaire with close-ended questions. In parallel, 512 French wine consumers participate to an Internet survey. This way, subject was approached from a twofold perspective: qualified researchers and French wine regular consumers.

Results show that surveyed expert seems to agree (in 63% of cases) with the idea of not changing a terroir by adding water under a controlled management of the water status in the vine. Level of agreement seems to be related with expert’s provenance and therefore expert’s observations in their local weather. Finally, concerning consumer’s approach, the level of implication in wine seems to play a role in accepting irrigation; consumers not implicated on wine don’t have a formed opinion whereas implicated consumers showed both; for and against a reasoned irrigation as a tool to deal against climate change. Moreover, within qualified consumers, age could serve for explaining the acceptance of irrigation: young (≤35 years old) and medium consumers (from 36 to 64 years old) were more likely to accept irrigation and a different grape variety to preserve wine quality.

The effect of cropload on the volatile aroma characteristics of ‘Beihong’ and ‘Beimei’ red wine

Beihong and Beimei were bred as winemaking cultivars released by Institute of Botany, the Chinese Academy of Sciences in 2008. The cultivars are selected from the population of ‘Muscat Hamburg’ (Vitis vinifera) ×V. amurensis. They are extended to most provinces in North of China because they have strong resistance to cold and disease and need not be buried in soil in winter. To better understand the effect of cropload on volatile compounds during wine-making, we surveyed volatiles composition and content of different cropload level in 3-years-old ‘Beihong’ and ‘Beimei’ vines which planted in east foot of Helan mountain of Ningxia (EHN).

Characterization of Glycosidically Bound Aroma Compounds of País cv. grapes of different Chilean zones

País grape has been estimated to arrive to Chile almost 500 years ago, being the first strain grown in this country. Traditionally, this grape has been used to mix with other varieties, to produce poor quality wines, but today is beginning to be used in the production of high quality wines. However, very little is known about the chemical characteristics of this variety. The aroma is one of the most important quality attributes of wine. Volatile compounds of this beverage may come from the grape (varietal aromas), from the fermentation process, from the ageing. The aromatic compounds are found in the grape in two forms: as free volatile compounds and as non-volatile compounds. The last ones, are aroma precursors present mainly as glycoconjugates formed by a sugar and an aglycone…
