Although the four main flavors – sweet, salty, sour, and bitter are all your tongue is really capable of tasting, the long lasting impression that wine leaves in your mouth is far more complex. When you drink or taste wine, your taste buds and your sense of smell are involved, adding to the way you interpret wine overall. The flavors, aromas, and sensations that wine is comprised of provide the interaction that you taste when you sample wine.
Sweetness is something that wines are well known for. With most types of wine, grapes are responsible for the sweet taste. Grapes contain a lot of sugar, which breaks the yeast down into alcohol. The grapes and yeast that were used to produce the wine will leave behind various sugars, which your tongue will be able to quickly detect. Once your tongue detects these various sugars, the stimulation of sweetness from the wine will be ever so present in your mouth.
Alcohol is also present in wine, although your tongue doesnt really know how to decipher the taste of alcohol. Even though the tongue doesnt really taste alcohol, the alcohol is present in the mouth. The alcohol found in wine will dilate blood vessels and therefore intensify all of the other flavors found in the wine. After you have samples a few types of wine, the alcohol level can easily have an effect on your taste buds, making it hard to distinguish other drinks that you may have.
Another flavor is acidity, which will effect the sugars. With the proper balance of acidity, the overall flavor of wine can be very overwhelming. Once you taste wine that contains it, the flavor of the acidity will be well known to your tongue. Although acidity is great with wine, too much of it will leave a very sharp taste. With the right levels, acidity will bring the flavors of the grape and fruits alive in your mouth – providing you with the perfect taste.
Yet another effect of flavor are tannins, which are the proteins found in the skins of grapes and other fruits. If a wine has the right amount of tannins, it will give your tongue a great feel, and bring in the sensations of the other flavors. Once a wine starts to age, the tannins will begin to breakdown in the bottle, giving you a softer feel to the taste. Tannins are essential for the taste of wine – providing the wine has been properly aged.
The last flavor associated with wine is oak. Although oak isnt put into the wine during the manufacturing process, it is actually transferred during the aging process, as most wines will spend quite a bit of time in oak barrels. Depending on how long the wine is left in the oak barrel or cask, the ability to extract the flavor will vary. Most often times, wine will be aged just enough to where the oak taste is visibly there – and adds the perfect sentiment to the taste.
