Science Behind the Shape

The glass bowl is based on the grape varietal.

A wine glass should be:

  • colourless
  • transparent
  • unadorned
  • thin-walled with a cut and polished lip
  • egg-shaped
  • made of crystal

The quality and intensity of the aromas are determined not only by the character of the wine but by the environment in which it is contained.

We have only 5 taste sensations on the tongue, but are able to distinguish between many thousands of olfactory differences. Therefore our sense of smell is a key factor in what we taste.

The shape of the bowl directs the wine smoothly onto the tongue, and traps the blanket of aromas that sit on top of the wine in the glass, capturing them for the nose.

Bouquet can only develop in a range of temperatures. Low temperatures temper the intensity, whereas high temperatures push mainly alcoholic fumes.

When wine is poured out, it starts to evaporate and the aromas quickly fill the glass in layers according to their density and specific gravity. The lightest vapors are at the rim, the heaviest on the bottom. Consequently the size and the shape of the glass can be fine-tuned to the typical aromas of a grape variety.

Physical movements and adjustments are controlled subconsciously. The shape of the glass forces the head to position itself in such a way that you drink and do not spill.

Wide open glass shapes require us to sip by lowering the head. Narrow rims roll the head backwards and the liquid flows because of gravity. This delivers and positions the beverage to different zones of the palate. Drinking in big sips to quench the thirst will diminish the influence of the vessel, and only the aftertaste will offer flavor. Alcoholic beverages are consumed according to their strength in small to very small quantities at a time. This gives the chance to control the flow where the beverage contacts the tongue. The resulting nerve message is delivered at a speed of 400 m/sec to our brain where it leaves a lasting first impression. In most cases we would be disappointed if the sweet fruit flavors were lacking, and tart components dominated the taste picture. If this occurs, the blame is usually put on the quality of the wine but never on the shape of the glass.

Cut Rim compared to Rolled Rim

Cut Rim - Wine flows smoothly onto the tongue

Rolled Rim - Inhibits the flow of wine and accentuates acidity and harshness
