Global warming, as we know, affects those who work the soil more than anyone else. Winegrowers are already finding themselves on the front line of the battle against the effects of “global warming”, sometimes with pitifully inadequate resources. Others are studying the possibilities of adapting vines to future climate conditions, which may turn the winegrowing world upside down in the coming years. To estimate the adaptation potential of grape varieties and get to know the wines that will be produced from them, Project “Oracle” has been rolled out by Bernard Magrez, owner of several grands crus classed among the most prestigious from the Bordeaux region. Eighty-four grape varieties are currently “being studied” in an equal number of temperature regulated vats, a unique device, borrowed from the aeronautic industry, that will make it possible to simulate the temperature model forecast for 2050 in the Bordeaux area.
