Soil management with respect to nitrogen mobilization and nutrient supply of grapevines on loess soil

What if, in 25 years, most wines were dealcoholized and flavored ? What if vines were only cultivated to combat erosion, store carbon, and provide anthocyanins…? What if climate change completely changed the list of vine varieties cultivable for wine production in France? What if food stores had completely disappeared in favor of virtual platforms? And if… because the long-term future is not predetermined and therefore not knowable, because the future is open to several possibilities, because the future does not emerge from nothing but from the present which conceals heavy trends and weak signals, prospective approaches make it possible to consider the room for maneuver that actors have to promote the advent of a future, which we can hope to be chosen, at least in part.

Differences in wine flavour proceed primarily from grape quality. Environmental factors determined by the climate, soil and training systems modify many grape and wine quality traits. Metabolic profiling based on proton nuclear magnetic resonance (1H-NMR) spectra has been proved to be useful to study multifactorial effects of the vine environment on intricate grape quality traits. The capacity of this method to discriminate the environmental effects on wine has to be demonstrated.

Increasing water scarcity and unpredictable rainfall patterns necessitate efficient water management in grape production. This study proposes a novel approach for monitoring grapevine water status in a commercial vertically-shoot-positioned Vitis vinifera L. Tempranillo vineyard using non-invasive spectroscopy with a battery of different AI methods to assess vineyard water status, that could drive precise irrigation. A contactless, miniature NIR spectrometer (900-1900 nm) mounted on a moving vehicle (3 Km/h) was employed to collect spectral data from the vines’ northeast side along six dates in season 2021.

Cultivation of a few number of clones is causing the loss of vineyard biodiversity, resulting in the disappearance of biotypes that could be of interest to face future challenges,

The purpose of the present study was to understand the overall concept of an aged dry white wine using a descriptive mental questionnaire. A total of 680 worldwide participants, grouped according to their involvement in the wine business, replied to an online questionnaire to characterize the sensory analytical and synthetic descriptors of an aged dry white wine. The descriptors were selected using a Check-All-That-Apply (CATA) approach concerning wine colour, aroma, taste, mouthfeel, and global appreciation.
