How to distinguish the true and the false of red wine
Four seas network: now the water in the red wine industry is very deep. After a series of high-rise packaging, the market value of inferior red wine has doubled several times or even a dozen times. Many friends who do not know red wine are hard to distinguish the quality of a bottle of red wine. Let's teach you some ways to distinguish real and fake red wine!
For most of our friends, can we really accept the taste of red wine? In fact, acid, bitter and astringent are the basic three flavors of red wine. We are used to eating spicy hot tongue and can't taste any fruit fragrance, flower fragrance and wood fragrance. It's no wonder that many Chinese people want to drink red wine with Sprite. Well, no matter what it's mixed with, as long as it's real wine, we don't care. We're afraid of meeting fake wine. The wine industry is now 'deep in water'. Some fake wines are packaged in high-end and high-grade atmosphere, but the cost is only a few yuan a bottle. According to industry insiders, it is very common for fake wine to be mixed with water. Some fake wine can be mixed with water in a single bottle up to 80%.
The essence of the program is to teach you how to identify the authenticity of wine.
The effectiveness of this method has reached 99.9%. The most important thing is that this test method is very simple, and what is needed is easy to find. It is edible alkali, which is sold in supermarkets.
Identification method I
[main ingredients] red wine, edible alkali and water
[other] napkin
[operation process]
1. Use a small half spoon of household edible alkali to put a little water to mix with it;
2. Prepare an ordinary napkin;
3. Drop a few drops of red wine on the napkin, the wine will spread evenly, and there will be no precipitation in the middle;
4. Drop the edible alkali water mixed with water on the red wine;
5. At this time, magical things happen. If the red wine turns dark blue, it is the real red wine. If there is no reaction, the red wine is fake.
Because red grape presents the natural anthocyanins of color, purple red in acid condition, and blue green in alkaline condition, which is also a color characteristic of many natural pigments. If the pigment is mixed, the color will not change.
Identification method 2, suitable for occasions outside the home
Put the white napkin on the table, drop a few drops of red wine, even diffusion is the real wine, that's because the false red wine pigment particles are large, it will precipitate in the middle of the paper towel, and the outward diffusion is just water trace.
The fake wine on the market is basically pigment blending, so the accuracy of these two methods is almost 99.9%. So why not 100%? That's another possibility. If the fake red wine uses grape skin pigment or other pigment that can change color due to different pH, it can't be detected, but the cost of using this method is not low and troublesome.
So at least we can know that if the red wine in our home does not change color with edible alkali, it must be fake, which is beyond doubt.
