I can drink it. It is a relatively common situation for wine to have sediment, because wine is made from grape fermentation, and the sediment is generally not filtered clean peel and pulp, many winemakers will deliberately leave some in order to maintain the aroma of wine, so it is normal for wine to have sediment, and in the case of wine without peculiar smell and no deterioration, even if there is sediment, it can be drunk. 1. The sediment in the wine may be the grape pulp and skin left over during winemaking, which is a relatively common situation.
2. If there is a crystal precipitate in the wine, it may also be tartrate, and in the process of making wine, tartaric acid and potassium combine to form a reaction, and such a crystal precipitate will occur.
What to do if there is sediment in the wine.
1. If there is sediment in the wine, you can put the bottle upright in a cool place, and the impurities will slowly precipitate to the bottom of the bottle, and you can pour it out and drink.
2. If there is sediment in the wine, you can pour the wine under the light source, pour the wine slowly, and stop when you see the sediment at the mouth of the bottle.

If there is sediment in the wine, it means that the wine has been aged for some time. Its precipitation will be divided into two types, one is the soft pigment precipitation formed by the precipitation of natural pigments. The other is the hard tartaric acid precipitate formed by the precipitation of tartaric acid.
Neither sediment can be drunk, just place the bottle upright before drinking, let the sediment fall into the bottom of the bottle, and then avoid the sediment when pouring the wine.
The wine has sediment at the bottom and can be drunk normally. Once the wine has reached the point of fermentation, the skins float on top, the color changes from dark to light, and the seeds and most of the flesh residue settle at the bottom of the bottle, at which point the residues should be separated from the wine. The specific method is to suck out the wine in the middle with a siphon, then put the residue into gauze, squeeze it by hand from light to heavy, and then twist it like a garment, so that the wine in the residue is basically clean.
Finally, all the liquor is mixed together and placed in jars to continue fermentation. At this time, the wine is very cloudy, you don't have to mind, the wine at this time is called Yuan wine. There is a layer of sediment at the bottom, which is the "corpse" and impurities of yeast after completing its historical mission, and this layer is used to make yeast paste industrially.
Extended information: Recently, the State Food and Drug Administration issued a consumption tip for home-brewed wine to teach you to make good wine. In order to improve the quality of home-brewed wine, it is recommended that consumers try to buy fresh, ripe and undamaged wine grapes when purchasing raw materials.
2. The fermentation equipment of self-brewed wine should be cleaned, disinfected and drained with hot water or highly edible alcohol before use; The temperature should be controlled between 15 and 25 during fermentation, and avoid higher than 30; Due to the large number of microorganisms in the epidermis of grape raw materials, it is recommended to add an appropriate amount of active dry yeast for winemaking before fermentation to achieve the purpose of inhibiting the reproduction of miscellaneous bacteria. It is strictly forbidden to add water to the fermentation vessel during fermentation.

If you open a bottle of wine and find sediment, don't rush to the fire, let alone throw it away, you may throw away a good wine. Generally speaking, it is normal for wine to have sediment in it, and it is basically harmless to the body, but sediment is also divided into types.
Some of the sedimentation is already present when the wine is bottled. When some wines are bottled, some unfiltered peel residues and the like will follow into the bottle to form a sediment, which helps to maintain the quality of the wine, and the residue will exude a rich fruity aroma after opening the bottle, so pay attention when pouring the wine.
Wine is a highly complex mixture, and the physicochemical precipitation produced by the wine, the crystalline precipitate that appears at the bottom of the glass, is actually tartrate, which is produced from potassium and tartaric acid, which is a natural product of grapes. Since tartaric acid is less soluble in alcohol than in grape juice, it will combine with potassium to form potassium bitartrate during the vinification process, forming this crystalline precipitate.
Pigments and tannins are also the main substances for the formation of precipitates after oxidation**. After the wine is bottled and stored for a period of time, there will be more or less granular, powdery or flaky sediments, which is a normal phenomenon, especially for some wines that have not been frozen and filtered, and the sediment is even more obvious, and the bottom of the wine bottle is made into a depression to facilitate the collection and separation of these sediments.
Therefore, the crystallization in the wine is not a quality problem, it is not only harmless, but a substance that must be produced during the fermentation and ripening process of the wine, which is a sign of the maturity of the wine. Because the unstable substances that affect the taste of the wine have been separated from the wine, the wine becomes purer, the taste structure is more stable, and the taste is more mellow and smooth.
What to do with sediment in wine?
If you want to open a bottle of old wine, you should remove it the night before and keep the bottle upright. This gives enough time for the sediment to sink to the bottom of the bottle, and the cork should be carefully removed and slowly poured into the glass to prevent the sediment from mixing with the wine. Wine over fifteen years old should remain upright for at least a week.
Before pouring the wine, keep your eyes at 90 degrees from the bottle, and slowly tilt the bottle to slowly pour the wine into the decanter when you start changing bottles; Be careful to leave the last sediment in the bottle on the shoulder of the bottle and not pour it into the decanter to ensure that there is no sediment in the decanter.

It is normal for drinking wine to have sediment, and wines that contain sediment are generally of good quality, unless you are drinking a blended wine. In both red and white wines, sediment generally does not appear in young wines.
Common sediment types.
1) Crystal precipitate.
2) Wine vat. 3) Protein.
4) Precipitation of grape skins.
5) Insoluble substances used in filtration.

Red wine is drinkable with a small amount of sediment, and it is normal for wine to have sedimentation. From the point of view of material composition and **, normal precipitation can be roughly divided into two categories. The first type is fine granular sediments, which usually appear at the bottom of the wine bottle.
This type of precipitation is often due to years of storage, in which the wine is subjected to micro-oxidation, in which the small molecules of pigments and tannins are continuously oxidized and polymerized, eventually forming macromolecule precipitation, which is produced only in red wines.
The second type is a crystalline precipitate formed by tartaric acid, which is usually attached to the cork or the inner wall of the bottle. This type of precipitation is due to the fact that the solubility of tartaric acid, which was originally dissolved in grape juice, decreases under low temperature and high alcohol content, and gradually forms glassy crystals, which are produced in both white and red wines, and are mostly in white wines.

The small amount of precipitation in the wine generally does not affect the normal drinking, on the contrary, it is precisely the sign of the wine's maturation, because the unstable substances that affect the taste of the wine have been separated from the wine, so that the wine becomes purer, the taste structure is more stable, and the taste is more mellow and smooth.
In the new wine standard in our country, there is a clear regulation on the clarity of wine, and a small amount of precipitation is allowed for wine bottled for more than 1 year. So don't worry when you find sediment in the wine.
Wine contains tartaric acid, an organic acid that crystallizes when the temperature drops; During storage, the combination of tartaric acid and tannins, wine pigments and other substances in the wine will produce flocculation; The iron ions in wine are oxidized when they are inactivated by oxidase, resulting in the formation of precipitates.
Precautions for storing wine
1. Bottled wine should be stored in a stable, dry, dark and cool place, which can prevent the inactivation of oxidase in the wine, and thus avoid the oxidation and precipitation of iron ions. In addition, it can also avoid the reduction of resveratrol, which has the effect of lowering blood lipids, antithrombosis and preventing coronary heart disease in alcohol;
2. If the bottle mouth has been opened, it should be sealed with a cork stopper, and the cork should be kept moist to prevent the turbidity or deterioration of the wine caused by the contamination of miscellaneous bacteria in the air;
3. For the bottled wine that has been opened, seal it completely, try to isolate the air or put a small amount of vitamin C tablets in the wine to prevent the oxygen in the air from reacting with the compounds in the wine and produce flocculents, and at the same time avoid the reaction between oxygen and phenolic substances and make the wine brown;
4. A small amount of lemon juice can be added to the wine to reduce its pH value, so as to further avoid the precipitation of tartaric acid crystals. At the same time, citric acid can form soluble complexes with iron ions, which can protect iron from oxidation and precipitation.

Red wine is made from fresh grapes through natural fermentation, and there is sediment in it, which is generally not filtered and left behind by grape skins, many of which are deliberately retained in the filtration by winemakers in order to maintain the original fruity aroma of the wine, which is a normal phenomenon. Therefore, as long as the red wine has not deteriorated, the sediment in it will not affect the consumption.

It's normal for red wine to have sediment, but if it has a strange smell, you can't drink it. Generally, the color of old wine will become lighter and there is precipitation, as long as it does not deteriorate, it will not affect the continued drinking. If the taste is not alcoholic, but has the taste of vinegar, rotten vegetable leaves, or even rancidity, it is spoiled and can no longer be drunk.
Generally, the normal precipitate is tartrate, the solubility of tartaric acid in alcohol is lower than that in grape juice, and during the brewing and storage process, it will combine with potassium to form potassium bitartrate, which is a common precipitation.
Although wine helps to protect the stomach and help digestion, people with gastrointestinal diseases should not drink wine, otherwise it can easily aggravate the condition.
For people with stenosis of blood vessels, if you drink too much red wine, it is not conducive to blood supply function, and it will also increase blood lipid burning and promote arteriosclerosis.

Red wine is drinkable if it has sediment. It is very normal for wine to have sediment, and sediment in red wine has no effect on the quality.
The precipitation in red wine generally comes from tannins and pigments or tartaric acid.
When you usually drink a bottle of red wine by yourself, you can stand up the bottle before opening the bottle and put it in a cool place to let the precipitation slowly fall to the bottom of the bottle. Since the whole process can take as long as a few hours, it is best to erect it a day in advance if it is an aged wine.
If you are not sure whether there is sediment in a bottle of wine, use a lamp to shine a light on the bottom of the bottle and use the light source to see if there is sediment in the bottle. However, it is important to remember not to shake the bottle before or after opening, otherwise the sediment will float.
When pouring the wine after opening the bottle, pour the wine slowly into the decanter, and if you don't have one, use a clean container with a thin mouth. Because a small amount of sediment is at the bottom of the bottle, most of the wine is clear when poured.
Red wine is a type of wine and does not necessarily refer to red wine specifically. The composition of red wine is quite simple, it is a fruit wine made by natural fermentation, and the most important thing is grape juice, and there are many ways to classify wine. In terms of the color of the finished product, it can be divided into three categories: clean red wine, white wine and pink wine.
Among them, red wine can be subdivided into dry red wine, semi-dry red wine, semi-sweet red wine and sweet red wine, and white wine can be subdivided into dry white wine, semi-dry white wine, semi-sweet white wine and sweet white wine. Pink wine is also called rosé wine and rosé wine. The bayberry made is called bayberry red wine.
