For the professional tasting and evaluation of a wine in the context of a wine evaluation or wine address, there are specially designed wine glasses. Due to their composition and shape, these are particularly well suited to optimally develop the aroma, bouquet and colour of a wine or to present it to the taster and thus enable an objective assessment. There are different manufacturers or brands. The glass most commonly used worldwide was developed by the French authority INAO in the 1950s. It has a short stem and a slender egg-shaped glass body. It has a capacity of 21 to 22.5 cl, and is only filled to about one third of its capacity for tasting.
In 1980 the DLG (German Agricultural Society) created the glass "Kabinett" for professional wine tastings (135 mm high). In the meantime it has been replaced by a new glass "Sensus" suitable for white and red wine, which was developed by the DLG together with Schott-Zwiesel (182 mm high). Three prototypes were tested intensively for two years. In the meantime the new glass has been adopted as a DIN standard. It has been in use at the DLG Federal Wine Award since 2000. The results were backed up by a principal component analysis of physical parameters. This also clearly showed that the intensity of the perceptibility of the various aroma substances increases with the height of the goblet and with the reduction of the opening diameter for white and red wine.
The glass is equally suitable for tasting white and red wines. It is characterized by a secure stand as well as good swivel and discharge characteristics and also meets demanding aesthetic requirements with its classic shape. For the tasting of sparkling wines, the "Sensus sparkling wine glass" is also available with a mousse point. The latest model "Sensus Black" enables perfect blind tasting. In this case, you have to rely exclusively on the palate and nose, as the wine colour is not visible. For the trained eye, the sight of the unknown wine in the glass is often enough for first insights. The deep black of the glass swallows any light, so that neither colour nor other characteristics of the wine are visible, thus ensuring the greatest possible objectivity.
The traditional French Tastevin is a traditional tasting bowl made mostly of silver, but it has no practical significance. See also under wine glasses, wine appeal, wine evaluation and wine enjoyment.
