Complementarity of measurements of electric resistivity of soils and ΔC13 of must in studies and valorization of wine terroirs

Abstract

The correlations between vine water deficit cumulated over the ripening period of grapes, assessed by ΔC13 in must sugar, and the main analytic variables of grapes are significant. As a result ΔC13 is a useful tool in zoning homogeneous areas according to their technological qualities when harvesting. There is no significant correlation between ΔC13 in must sugar and soil electric resistivity in the same zone. Thus it is impossible to combine a few measurements of ΔC13 and a zoning of electric resistivity to distinguish areas of which the aptitudes are different. In the event of little water deficit (ΔC13<-25,5‰), a pedological study based on zoning by means of electric resistivity is a complementary tool of zoning according to water uptake conditions, since harvest quality varies a lot with the texture of the sub-soil and its geophysic behaviour.

Evaluation of the enological potential of red grapes in southern Brazil

The Campanha Gaúcha is located in the pampa biome and has unique characteristics, as it is the hottest producing region with the lowest volume of rain in Southern Brazil. Furthermore, the large extensions of flat or low-sloping areas, harsh winters and great sunshine during the ripening period, made this the second largest producer of fine wines in Brazil.

Evolution and sensory contribution of ethyl acetate in sweet wines

Ethyl acetate (EtOAc) is the main ester present in all wines, generally produced by yeasts during alcoholic fermentation and sometimes by bacteria during barrel ageing. Its odor is characterized by solvent notes, which give wines their acescent note [1].

Viticultural sites and their valorisation in Istria (Croatia)

Pratiquement tout le territoire d’Istrie possède les bonnes conditions naturelles pour la viticulture, laquelle dans ce lieu a une tradition millénaire. La viticulture était et reste toujours la plus importante branche de production agraire et d’économie. Les sites viticoles en Istrie sont caractérisés par des diverses conditions naturelles.

What drives Indications of Geographical Origin protection and governance mechanisms in the U.S. and European contexts? A contribution of the social sciences

There are fundamentally two different ways in which indications of geographical origin (igos) can be protected. The us approach favors the pre-existing trademark system through collective marks (cms), while the eu approach favors a maximalist approach via a sui generis system which promotes appellations of origin (aos). A consensus however emerges regarding the fundamental protection of origin against misleading, confusing and dilutive uses. Previous literature discusses these competing igo logics from historical, legal and international trade perspectives. In this paper, we depart from the field of social sciences, in particular from recent advancements in the well-established literature on proximities, in order to provide a reflection on the different logics underpinning the aos and cms systems.
