The glass bottle is the least likely to leak gas, so the taste is the best.
The difference between a plastic bottle and a metal can is that the plastic is a polymer material, and the arrangement between the molecules must be such that there is no tightness between the metal atoms, thereby causing the carbon dioxide to leak more easily, and the gas in the carbonated beverage of the same glass bottle is also Not easy to leak. Therefore, the glass bottle and the canned cola are better than the plastic bottle.
In the process of transportation and storage, the two methods of plastic bottle and canned can cause pressure drop due to deformation of the package, and the glass bottle does not have this problem. In addition, the permeability of glass, cans and plastic shells may still differ. The glass is stable in nature, and the inner wall only needs to be cleaned and can be used; however, the inner wall of the can made of aluminum alloy is actually coated, and the inner wall of the plastic bottle is similar. Plastic or plastic coatings may react with the cola liquid during storage, affecting the mouthfeel.
Different parts of the tongue touch the drink first, and the taste is different.
Some people think that because of the different shape of the opening of the can and the plastic bottle, the contact position with the tongue is different, which in turn causes the difference in taste: when drinking the can, the cola touches the front part of the tongue, the taste bud is rich, and it is more sensitive to bubbles and sweetness. Therefore, I feel that the taste is better. When drinking a bottle, cola directly pours into the back of the tongue, the taste is not as good as the former, but because a lot of bubbles directly into the stomach, it will feel more refreshing.
