winemaker Ulrich Allendorf has been invited to a wine tasting to Oestrich-Winkel in the Rheingau. In the case of a neutral white light, he gives his guests a glass of Riesling for tasting. It tastes fruity, slightly dry. A little later the next round. The wine that is now driving up to a red light in the room, appears to the experts, fruity and sweeter than the previous one.

again and again, the winemaker changed the light in the room, then Red, then Green, then Blue and finally Yellow. The green light served the wine in front of the connoisseurs of sour and immature, the blue light kredenzte watery. In yellow light, the wine tastes harmonious – perfectly balanced between sweet and sour.

The remarkable thing: It was always the same wine. The different taste, the experts have only imaginary, of the different coloured light trails. A deception of the senses.
