Scientists in Spain Look to Old Vines to Save Wine Business
Genetic researchers in Spain’s wine country believe grape vines that have lived for more than 35 years are better able to deal with high temperatures brought by climate change.

Are my bubbles shrinking? A deeper look at oxygen desorption in wine
In the past decade, there has been an increasing amount of work dedicated to understanding micro-oxygenation in wine. Oxygen desorption into nitrogen gas is a similar process, but there has been little work focusing on this process and no work explicitly examining the effect that changes in wine components have on the process. The removal of excess dissolved oxygen from wine prior to bottling is commonly done in winemaking. A widely used method involves sparging nitrogen through the wine, in a process known as desorption. An indicator of the rate of oxygen desorption (DO) is the oxygen volumetric mass transfer coefficient (kLa), which can be determined experimentally. The aim of the study was to examine how temperature, superficial gas velocity, and ethanol and glycerol levels affected the kLa of dissolved oxygen into nitrogen gas in an aqueous solution of ethanol and glycerol.

A robot will use hydrogen fuel cells in vineyards 12 December 2022 19:03 |

A robot will use hydrogen fuel cells in vineyards
At the Vinitech trade fair in Bordeaux, the Exel group showcased an environmentally-friendly prototyping of Traxx using a new fuel, namely hydrogen. To achieve this, Exxact Robotics, the research centre for the Exel Industries group, and Fétis Group, via its subsidiary Dintec, have joined forces. The partnership has produced the Traxx Concept H2, the first autonomous green hydrogen vineyard tractor. More specifically, Dintec has designed a hydrogen-powered generator comprising the hydrogen fuel cell, hydrogen storage, the secure control and command of the unit and its integration into the machine. The standard hydrogen fuel cell from the road market (buses, trucks, etc.) was customised for this system to include all the functionalities required for agricultural use.
