To fully appreciate the personality of different grape varieties and the subtle character of wines, it is essential to have an appropriately fine tuned glass shape. The shape is responsible for the flow of the wine and consequently where it touches the various taste zones of the tongue. The initial point of contact depends on the shape and volume of the glass, the diameter of the rim, and its finish (whether it is cut and polished or rolled edge) as well as the thickness of the crystal.
As you put your wine glass to your lips, your taste buds are on alert. Once the tongue is in contact with the wine three messages are transmitted at the same time: temperature, texture and taste. Wine is composed of different elements: fruit, acidity, mineral components, tannin and alcohol. The combination between the sense of smell and taste leads into the wonderful world of flavour.
It is the glass shape which is responsible for balance and harmony of flavours. RIEDEL was first to discover the concept: ”The content commands the shape!”
