The truth, now just know what are these sediments of wine?

When we drink wine, we always meet wine with sediment, but we don't know much about wine, and we don't know whether these wine with sediment can be drunk. Let's know the composition of these sediments in detail and see if drinking wine with sediment is harmful to our health.

tartar

Tartar, the crystal of wine, is mainly composed of Tartaric Acid from wine, because wine is stored in a low temperature environment. The shape of tartar crystals is irregular and sometimes sticky, usually attached to the bottom of the bottle, the shoulder of the bottle or the bottom of the cork.

Crystallization in wine is not a quality problem. It is not harmful, but a substance that is bound to be produced during the fermentation and ripening of wine, especially during the ripening process. This is a sign of wine ripening. Only high-quality wine will have sediment, namely tartar. Because the unstable substances that affect the taste of wine have been separated from the wine, the wine becomes pure, the structure of wine taste is more stable, and the taste is more mellow and smooth.

distiller's grains

distiller's grains are Sur Lees, which are the most common in French Muscadet wines. In fact, "Lees" is an old English word, which is used to describe the dregs or sediments that sink to the bottom in a container like a fermentor. So "Sur Lees" means that there is precipitation on the surface of wine. When distiller's grains appear on the surface of wine, the winemaker will stir the wine every day, which can make the wine taste richer. In addition, distiller's grains are also common in aged sparkling wine.

Grape peels precipitate

When drinking wine, you may find some small black crumbs at the bottom of the glass, which are actually grape peels. Unfiltered red wines, such as Cabernet Sauvignon and Syrah, often have sediment in their bottles, but it is not common for light-bodied red wines to contain sediment.

protein, phenols and insoluble substances used in filtration

protein belongs to the category of microorganisms, so the color of wine containing protein is not so pure. Red wine, after phenolic polymerization, will form colored tannins, which is especially obvious in aged Porter. In addition, in filtered wine, some of the added filtering substances are insoluble, so precipitation will also occur.

Can the wine with sediment still be drunk?

The wine with sediment tastes more suitable. This is because there are often some unstable substances in new wine, which are not easy to combine with wine, so it will disturb the taste of wine. However, after a period of storage, these unstable substances have a biochemical reaction with wine and become crystals. So that the wine becomes more pure. To some extent, the appearance of sediment is also a sign of wine maturity. At this time, the wine has a smoother structure and a mellow and smooth taste.

do these precipitated substances sound healthy?

Many consumers are worried that the precipitation in wine (especially the crystal precipitation produced by tartrate) will affect their health. In fact, these wine deposits will not have a negative impact on human health. Tartaric acid is an organic acid existing in grapes and an important source of wine acidity. They are harmless tartaric acid crystals and will not affect health. Of course, these deposits are not particularly good for your health, so you don't need to drink them deliberately.

How to drink wine with sediment

Because some sediment substances in wine, especially peel sediment and phenols in red wine, will make the wine taste bitter and unpleasant; In addition, it will affect the clarity of the appearance and color of the wine, so the wine with precipitation needs special service-sobering up before drinking, and the methods are as follows:

1. Before deciding which bottle of wine to drink, the wine bottle should be kept in an upright state. Wines over fifteen years old should be kept upright for at least one week;

2. Before sobering up, you need to prepare a sobering up device, funnel, filter cloth and a light source;

3. When opening a bottle, don't shake or turn the bottle. After opening the bottle, observe the bottom of the bottle through the light source to make sure that the sediment has not polluted the liquid above.

4. Before pouring wine, look at the bottle at 9 degrees. When changing bottles, slowly tilt the bottle and slowly pour the wine into the decanter.

5. Pay attention to leave the last precipitated wine in the bottle on the bottle shoulder, and do not pour it into the decanter to ensure that there is no precipitation in the decanter.

After knowing this knowledge, you don't have to worry about seeing these sediments when drinking wine. After all, the better the wine, the easier it is to have sediments. At the same time, it indirectly shows that the wine you bought is a good red wine. Just open a bottle and enjoy it!
