- Sugar is immediately perceived on the end of the tongue.
- Acidity is perceived on the sides and under the tongue and the taste persists.
- Salt is rapidly noticed on the front edges of the tongue.
- A bitter taste is perceived slowly on the back part of the tongue and the taste remains for a long time.
In the same manner as the nose, the perception in the mouth develops in several stages: The attack, the middle of the mouth and the finale.
The attack is the first sensation and can be frank, keen or soft.
The middle of the mouth: the flavours develop on the tongue. There one determines if the wine is sharply refreshing, round, full or, on the contrary, empty.
The finale, also know as ‘length' or aromatic duration, is the time - in seconds - (‘caudalies') in which the taste remains in the mouth after the wine has been swallowed or spit out.
