See whether the red wine has aging ability, which is available on the market 95 More than % of red wines do not have the ability to age. Those red wines that do not have the ability to age are not better the longer they are stored. The best drinking period depends on the storage environment, the selected grapes and the winemaking process. But there are also some red wines that have the ability to age and can be stored for decades or even hundreds of years. The aging ability of red wine mainly depends on the intensity of tannins contained in the wine and the type of grapes. For example, Cabernet Sauvignon is more suitable for making aged wine. There is a way to identify whether wine can age. This is to buy a dozen bottles of the same wine and open a bottle every six months to taste the taste. If the internal structure does not change much within two or three years, it means it can be kept longer.

Look at the vintage of the red wine, even if it is from the same winery and the same winery Brands and red wines are also different from year to year. This depends on the rainfall, temperature, lighting, etc. of the year. Take the Bordeaux region in 1995 as an example. This year, the summer temperature was high and slightly dry, and the grapes grew better. In addition, October was dry. The alternation of hot days and some humid weather provides good conditions for the growth of noble rot, so the quality of red wine this year is higher.

Look at the date of the red wine. The shelf life is generally ten years, but it is best to drink it within 5 years, because red wine has a decline period, and the longer it is stored, the worse the taste (except for red wine with aging capabilities). It is best to drink it at its peak, but it is difficult to grasp the peak period and must be analyzed from many aspects.

Some red wines are marked with the year of the wine, such as 2005 dry red wine, which means it was produced in 2005. No matter when you buy it, the shelf life must be calculated from 2005.
