What is the sediment in wine? Why is there precipitation?

Some friends asked, if there are impurities or black dregs in the wine, is the wine expired or broken? Why is there sediment in wine? What exactly are these deposits?

The brand LEESON red wine of Yuncang Winery shares that there are generally two types of sediments, one is tartaric acid. Wine is fermented with fresh grapes as raw materials. During the fermentation process, there will be a substance called tartaric acid. This substance will appear as a crystalline substance at low temperature, and the chemical reaction produced by the unstable substance inside will sink. The substance is the sediment that we usually see in wine. The second type, which is more common in old wines, is the flake-like sediment, which is mainly composed of pigments and tannins.

If you look closely, there will be some sediment in almost every bottle of wine, which is very normal. These precipitates are granular and vary in size. Then, some people are worried, will these sediments affect the quality of wine?

The brand LEESON red wine of Yuncang Winery continued to share that these sediments do not harm the human body or the quality of the wine. Red wine with sediment will not affect the quality, but it shows that it is a sign of red wine maturity. Only high-quality wines will have this kind of precipitated "tartar". If the "gems" in the wine can also be found in younger wines, this proves that the wine is rich in minerals.

How to drink good wine with sediment?

The first step is to keep the wine upright before drinking to allow the sediment to sink to the bottom of the bottle. If it is a wine that has been aged for many years, it should be established and kept upright for more than a week.

The second step is to prepare the decanter, as well as the light source and filter. If it is too late to prepare the filter, you can omit it, and tear off the wine cap. Try to choose a gentle way to open the bottle, and you can use an old wine corkscrew. Do not turn or shake the bottle when opening the bottle to avoid raising the sediment and contaminating the wine above.

The third step is to prepare to pour the wine. The eyes are at 90 degrees to the wine bottle. Slowly pour the wine from the bottle into the decanter. This process needs to be carried out under the light source, so that you can see the sediment in the bottle. Sediment remains on the shoulder of the bottle. If sediment appears on the shoulder of the bottle, stop pouring. Then pour the wine in the decanter into the glass, and you can taste the wine elegantly.
