Chilled water tastes different than warm or boiled water. What is the reason for this?
In: Chemistry
Assuming that it’s the same water and not from different sources which may contain different salts.. there are 2-3 major factors
1. The temperature itself. When water touches our taste buds, the temperature sets off slightly different responses to the brain.
2. The material. Chilled water may be stored in any container- plastic/glass/metal. Warm/Hot water is almost always used with metal and sometimes glass. So this is also a small factor.
3. Gases. The most important factor is gases. If a liquid surface is kept in contact with a gas, the gas WILL dissolve in the liquid slowly. The colder the temperature, the faster the gas will dissolve in liquid and vice versa. Boiled water is thus absolutely devoid of gases ( bud-bud-bud-bud bubbles, remember? ). That’s why bottled water tastes sweet while boiled water tastes bitter. Oxygen.
