7 extremely accurate ways to identify real and fake wine you need to know during Tet

1. Volume of wine in the bottle

Usually wine is bottled automatically, so the volume of wine in the bottles is very even. Meanwhile, if counterfeiting these bottles of wine by hand, it is difficult to avoid the bottles being full or empty differently (although the difference is not large, but the observant can still notice).

When choosing wine, first observe the row of wines from the same brand to see if the volume of the bottles is the same. Then check the next factors.

2. Check for air bubbles in the bottle

Another experience is to observe the bubbles rising by turning the wine bottle upside down. If it is real wine, the bubbles will be very fine and even, moving slowly, not vertically, but spreading out and then gradually rising. Looking above, you will see slightly larger bubbles clinging to the bottle.

If it is fake wine, the bubbles will be larger and tend to rise vertically at a faster rate. If it is made from industrial alcohol, the bubbles will stick to the bottle wall.

3. Check the bottom of the bottle

Many professional counterfeiters also use the method of drilling a very small hole in the bottom of the bottle to pull out the real wine, then pump in fake wine. So, when choosing wine, you should flip the bottom of the bottle to observe, if you see a small hole or any unusual signs, you should not buy it.

However, these holes are very difficult to detect, usually in "dangerous" places such as the gaps between the letters A, B, O or places that few people pay attention to... You have to be very observant to be able to detect these holes.

4. Tin stopper on bottle cap

For real wine, the cork on the bottle cap is usually closed by machine, the tightness and safety of the wine is very good so you can easily turn the cork. As for fake wine, turning the cork will not be easy because they are usually closed by hand.

5. Use baking soda

Add a little baking soda to the wine, if the wine changes color or becomes darker, it is real wine. Fake wine will not change color because the additives do not react with the baking soda.

6. Use white vinegar

Using baking soda can only detect fake wine, but to check whether the wine is 100% from grapes or not, you need to use white vinegar.

How to do it: If the wine still has a color change after the baking soda test, add a spoonful of white vinegar. If the wine immediately returns to its original purple-red color, it is real wine from grapes.

7. Use chalk to write on the board

Pour a drop of wine on a piece of chalk. If the drop of wine on the chalk becomes brighter after drying, it is real wine. If the drop of wine is darker, causing the chalk to change color significantly, it proves that the wine contains chemical dyes.
