Water status modelling: impact of local rainfall variability in Burgundy (France)


Water status is a key factor in vine development and berry ripening. Water status is strongly affected by environmental parameters such as soil and climate. Whereas at local scale the soil variability is frequently accounted for, little scientific reports are available concerning the impact of local rainfall variability on grapevine water status. In order to accurately register the space and time variations of rainfall at local scale, a dense rain-gauges network has been installed in Burgundy. It is composed of 45 rain-gauges over a 28 km² area. Rainfall data collected by each rain-gauge in 2014 and 2015 was used as input variables in the grapevine water balance model proposed by Lebon et al (2003). All other climate variables, vineyard and soil parameters were kept strictly identical for each simulation in order to capture the consequences of the sole spatial variability of rainfall on vineyard water status.

As rainfall dynamics impact on the vineyard depends on the soil water content, water balance was modeled considering successively soils with low (50 mm) and medium (150 mm) soil water holding capacities, representative of the soils of the area. The daily fraction of transpirable soil water, averaged on the grape ripening period, was used as an output variable to assess the potential consequences of soil water status on grape characteristics.

During the 2014 (2015) vintage, the mean FTSW from veraison to harvest varied from 0.22 to 0.41 (0.09 to 0.25) for soils with low water capacity with an average difference of 0.04 (0.03). Ranges of 0.31 to 0.76 (0.09 to 0.16) with average differences of 0.09 (0.02) were observed for soils with higher water capacity in 2014 (2015). Therefore, it seems that the spatial variability of rainfall at local scale could significantly affect the vineyard water balance, depending on the vintage and the soil water capacity.
The contribution of local rainfall variability to vineyard water balance in comparison to other factors also impacting the vineyard water status is discussed.

Managing precision irrigation in vineyards: hydraulic and molecular signaling in eight grapevine varieties

Understanding the physiological and molecular bases of grapevine responses to mild to moderate water deficits is fundamental to optimize vineyard irrigation management and identify the most suitable varieties. In Mediterranean regions, the higher frequency of heat waves and droughts highlights the importance of precision irrigation to meet vine water demands and demonstrates the necessity for a deeper understanding of the different physiological responses among varieties under water stress. In this context, previous reports show an interplay between stomatal regulation of transpiration and changes in leaf hydraulic conductivity, also with the involvement of aquaporins (AQPs), particularly under water stress. However, how those signaling mechanisms are regulated in different grapevine varieties along phenological phases is unclear.

Les motivations du vigneron en quête de l’expression “terroir”

During the 1985 harvest, I was able to notice in the taste perception a break in the harmony of the wine during even partial blends of grapes from different plots. At the same time, I noted a good reaction from customers for greater product customization. As a result, I was led to seek the objective limits of the terroir of a cuvée and by a constant and permanent refinement of the parameters specific to each of the terroirs.

Dynamics of Saccharomyces cerevisiae population in spontaneous fermentations from Granxa D’Outeiro terroir (DOP Ribeiro, NW Spain)

Granxa D’Outeiro is a recovered ancient vineyard located in the heart of DOP Ribeiro, where traditional white grapevine varieties are growing under sustainable management. Spontaneous fermentations using grape must from Treixadura, Albariño, Lado, Godello, and Loureira varieties were carried out at experimental winery of Evega. Yeasts were isolated from must and at different stages of fermentation. Those colonies belonging to Saccharomyces cerevisiae were characterized at strain level by mDNA-RFLPs.

Effect of alcoholic strength on the phenolic and furfural compounds of Brandy de Jerez aged in Sherry Casks®

Brandy is a spirit drink produced from wine spirit aged for at least six months in oak casks with a capacity of less than 1000 L and minimum alcohol by volume (ABV) of 36%. During the aging process, physicochemical and sensory changes take place. Manifested by colour, flavour or aroma variations that improve the quality of the initial distillate.

Physico-chemical properties of vine pruning residues with potential as enological additive

Grapes are one of the world’s primary fruit crops, and pruning activities generate high amounts of annual wood wastes [1]. These pruning shoots contain valuable phenolic compounds and could have numerous potential applications [1,2]. Consequently, the aim of this work was to evaluate the physico-chemical properties of vine pruning residues with potential as enological additives. For this purpose, grapevine shoots from 12 varieties grown in Chile were collected during the winter of 2021.
