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. Table wine, the third category, is wine in it s natural form - which is different from any other type of wine. Normally, grapes are the preferred ingredients for making wine. They contain an equal amount of acid and sugar, which can t be found in any other type of fruit. When drying the grapes, a high amount of heat is needed. When this happens, the flavor and quality of the wine won t be any good. Wine that is damaged from heat loses all of it s flavor and color, making it virtually impossible to drink - or sell. Colder temperatures on the other hand may slow the aging process, although it can also prevent the wine from getting the chemical reactions it needs as well. On the other hand, vertical racks can come in handy when storing wine for short periods of time, or wine that is best consumed young. Tilted racks are another type of rack you should avoid using, as they can dry out the corks or deposit the sediments too close to the cork. For your wine storing needs, you should always go with a horizontal rack. Wine lovers who want to open a bottle of wine every now and then, and keep the cork in great shape will truly appreciate the gift of a corkscrew. Corkscrews are also used in restaurants as well, as they can easily remove even the toughest of corks. Another great gift that relates to wine is the pocket vineyard, which is an electronic device that contains a wine glossary, vintage wine charts, and even suggestions and ideas for pairing wine with food. Light causes the wine to age prematurely, making it in your best interest to store wine in a dark location. To prevent damage to the wine from sediment, you should also store wine in a location that is free of vibration. If you store wine in places that are free from vibration, it will give the sediment in the bottle ample time to settle.
