The wine mainly has to be decanted to be able to taste it better. Decanting a wine means moving the liquid from one container to another, known as a decanter, to remove sediments and imperfections. Although these are part of the wine, since they have a bitter taste, it is not pleasant to find them in the glass.
Decanting also allows the oxygenation of the wine, since when decanted, the confinement aromas of a wine that has been bottled for a long time disappear. As it is a living organism, its sensory characteristics improve with oxygen after opening the bottle, its specific aromas appear that are often hidden by the time the bottle has been sealed. It is for this reason that many times the last glasses of the bottle taste much better than the first, because the wine is already oxygenated. In addition, it will be important to have properly preserved the wine to keep all its properties intact.
Many times we will have seen people stirring the wine inside their glass, they do this to decant it, although this method is not as effective as decanting the wine into another container. It must also be taken into account that with too much oxygen the wine begins to evolve worse, unfavorable to its taste, after a few days open, although a slight contribution of oxygen during the fermentation of the grapes can help change the quality and final color. Of the wine.
Differences between decanting a young wine and an old one
To decant a young wine we only have to open the bottle and empty it into the decanter, but for an old wine we have to open the bottle and empty it very slowly, observing that with the light (normally that of a candle) that the sediments are removed. remain in the neck of the bottle and do not fall into the decanter. The result will be an exquisite wine without bitter flavors due to imperfections.
It is not enough to open the bottles in advance to oxygenate them, since physics has shown us that, in the neck of the bottle, there is not enough space for oxygenation. The best way to do this is to decant it into another glass container.
