Human odorant receptor for characteristic petrol note of Riesling wines identified

Climate change does not stop at grapevines. Too much sun means that the bouquet of German Riesling wines becomes dominated by a petrol note (some) customers do not appreciate. A research team from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has identified the human odorant receptor responsible for the perception of this special aroma. Their paper is published in the Journal of Agricultural and Food Chemistry.
