For the professional tasting and assessment of a wine within the framework of a wine evaluation or wine talk, there are wine glasses specially developed for this purpose. Due to their composition and shape, these are particularly well suited to optimally develop the aroma, bouquet and colour of a wine and to present them to the taster, thus enabling an objective assessment. There are various manufacturers and brands. The most widely used glass in the world was developed by the French authority INAO in the 1950s. It has a short stem and a slender egg-shaped glass body. The capacity is 21 to 22.5 cl, for tasting it is only filled to about one third.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
