How to distinguish true and false red wine? Practical tips for distinguishing true and false red wine
4hw.com.cn: for friends who don't understand red wine, sometimes they are easily cheated by packaging. There are many fake and shoddy red wines on the market. Many friends don't know how to distinguish true and false. Let's teach you some methods to distinguish true and false red wines!
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. What you need is easy to find, that is, edible alkali, which is sold in supermarkets.
Identification method I
[main ingredients] red wine, edible alkali, water
[Others] napkin
[operation process]
1. Add a little water with half a spoonful of household edible alkali to boil 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 alkaline water mixed with water on the red wine;
5. At this time, a magical thing happened. If the red wine turns dark blue, it is real red wine. If there is no response, the red wine is fake.
Because the natural anthocyanins of red grapes show purple red under acidic conditions and blue-green under alkaline conditions, which is also a color characteristic of many natural pigments. If the pigments are mixed, the color will not change.
Identification method 2, applicable to occasions outside the home
Stack the white napkin on the table, drop a few drops of red wine, and the uniform diffusion is the real wine. That's because the pigment particles of fake red wine are large, which will precipitate in the middle of the napkin, and the outward diffusion is just water marks.
The fake liquor on the market is basically pigment blending, so the accuracy of these two methods is almost 99.9%. So why not 100%? That is, there is another possibility. If the fake red wine uses grape skin pigment or other pigments that can change color due to different pH, it will not be detected, but the cost of this method is not low and troublesome.
So at least we can know that if our red wine does not change color with edible alkali, it must be false. There is no doubt about this.
