It is also important to use the appropiate glass for tasting wine.
We cannot use just any. Usually the professional Wine tasters use the standarised glass Afnor, that at a time was used all over the world.
Nowadays, it?s been substituted by other glasses that seem to be more suitable and above all more revolutionary and that with no doubt will go on changing, in the future.
In any case the glass should have certain characteristics. A good wine tasting glass should be made of fine glass, plain, colourless, limpid and of straight and pure forms, without decoration or odd corners.  Before each wine region used to have its own wine tasting glass model.
Now there is a tendency towards homogeneity of forms as well as sizes, adjusted to the unanswerable experts advise.

The most used seem to be as we have already commented before, a transparent and fine crystal glass, that allows the judging of the wine without strings attached, ball shaped, lightly closed at the top, to avoid the aromas to escape and to let the content swirl easily, a slim stem allowing to hol the glass without needing to put a single finger in the wine, because the fingerprints could be marked or the heat could be transmited to the wine. These are the necesary qualities of an ideal tasting glass. All these requesites are accomplished by the glass “Oenologue”, from Bordeaux, that is being accepted by other Wineries. It?s possible that this glass “Oenologue” ends up by displacing the classical tasting glass Afnor, smaller in size and not so nice.

It may be difficult to understand for the profanes that a variation in size or a couple of milimetres in the thickness of the glass may affect the final result of something as traditional as it is wine, but it is like this. The art of tasting wine is a sensorial game, where alll the perceptions, no matter how light they are, will end up by being valid. Therefore the content is necessarily decisive in it.
In this respect wine tasters have made several tests with different glasses to realise that the same wine expresses itself differently, depending on the glass it is poured.
