First, look at the price. If it is too low, then most likely you are offered to purchase a surrogate. To make a bottle of natural wine, you need to spend money on it production , which is not very cheap, as well as bottling, transportation, storage. In this regard, the production of powdered wine is much cheaper , respectively, and cost its in the store is pretty low.
Be careful when buying wine in boxed. Since the use of such containers is cheaper than glass bottles, they are often used not by the most conscientious manufacturers .
When buying wine, pay attention to the label. An excerpt will not be indicated on a bottle of powdered wine, nor can such wine be vintage. Such a drink has a sweet, cloying taste, does not have the aftertaste characteristic of natural wine. Most often fake sweet, semi-sweet and semi-dry wines. But dry ones are always natural, since faking them is very difficult and expensive.
You can check the naturalness of the wine in the following way. Take a bottle, sharply turn upside down. Take a good look at the remaining sediment. In natural wines, it is allowed, but it should not be much, and it has a rather dense consistency. If you have a surrogate, then there can be a lot of sediment, and it will be loose.
Pour some wine into the glass. Shake in a circular motion. If there are traces on the walls of the glass, the so-called “wine legs”, then this is a natural product. The longer these tracks last, the better the wine.
You can drop a couple drops of glycerin into a glass of wine. If it sinks to the bottom and does not change color, then the wine is natural. If the glycerin turns red or yellow, then you have a fake.
Fill a deep bowl with water, pour wine into a vial, pinch the neck with your finger. Dip the vessel with the drink into water and turn it over. Remove your finger. If the wine begins to mix with water, then this will indicate that the drink has additional impurities, flavors and other additives. Natural wine will not mix with water.
