The winegrowers of the Rhine Valley know all the secrets of Riesling, the German varietal par excellence, a wine that has been grown for centuries in this region thanks to the resounding influence of the river. However, over recent years, they have become aware of the harmful effects of global warming on their vines, a phenomenon that is increasing and which could well put the growing of Riesling at risk.
In order to preserve the typicity of their white wine, growers are today gambling on new skills acquired by scientists.
At the University of Geisenheim, students and professors have developed a technique that is unique in the world: an experimental vine that can simulate global warming over the next 50 years.
