Smelling is important to appreciating wine. The part of the brain that houses our ability to taste is called olfactory center where there is a bulb that forms part of the brain. As wine is swallowed, internal pressure in the mouth forces the aromas into the olfactory mucosa. The "signals" and then sent via neurons to the olfactory bulb. As wine is warmed in the mouth aromas are intensified.

Sensations in the Mouth:

The taste of the wine has different sensations in the mouth. Whilst it is common knowledge that our tongues are most sensitive to the sweetness at the tip of the tongue, and saltiness on the either side and over the top of the of the tongue near the front. We feel the sourness along the sidesof the tongue but further back and you may feel the bitterness on the rear top of the tongue. Mouthful and Textures
Mouth feel is a term that advanced tasters always refer to as a quality parameter of the wine. It is the sensory perception of touch and texture or tactile sensations on the surface of the oral cavity, including the filiform papilla that send signals via the trigeminal nerve to the brain about textural differences in food and wine. It is interesting to note that astringeny, body, viscosity, bitterness, and acidity in a wine are interrelated.

There are some other sensations of the mouth feel that are divided into the following way.

Irritating - Ranging from the Spritz and Prickling to Tingling and Peppery.

Heat - Ranging from the Chilli Hot to Warm for example High alcohol wines.

Textural - Creamy, syrupy for example sweet wines.

Weight - Viscious, full or thin and watery from low alcohol and low acid wines

Acidity - Metallic, steely, sour, soapy

Flavour - Concentrated, active and intense.

These are all generalizations that are researched but there can be more to it and it is all the more interesting to know about these facts that are so true but not very much noticed.
