But at the beginning there is the act of drinking and the pleasure of alcohol is not in the savour. This is explained by the double oral, tactile and gustatory innervation . Alcohol has precisely the property to excite these nerves and this wakes up the oral organ to the conscience by creating inside a feeling of plenitude . Any one can notice this by tasting a strong liquor. This sensitivity is distinct from the taste which recognizes only the substance.
Alcohol thus reveals to the conscience the mouth itself.
This is a part of the pleasure. The faculty of an organ to occupy a field of the conscience or to withdraw itself is a phenomenon related to a need, the impulse and its satisfaction. It is thus for the stomach and hunger, or erotic excitation. Without taste or odor, the carbon dioxide contained in sodas operates in the same way on the mucous membrane inside the mouth. The cold or the heat works in the same manner and beer is good with freshness, CO2 and alcohol.
