Whenever you are out on the town, you might have noticed that most water carafe’s come with a glass that you very neatly place over the top, to act as a lid. Aside from being a great idea, there is a legitimate and a cool scientific reason behind this.
Does Water Expire?
Scientifically speaking, the water that is around now is the same water that filtered through prehistoric animals. There is no such thing as “new” water, so the question is: can it really expire? Well, yes and no. Water doesn’t expire per se, but it does have a chemical reaction after being exposed to open air, which changes the composition slightly and thus affects its taste.
When water is exposed to the air, carbon dioxide from the air reacts with the water and makes the water’s mineral composition more acidic. This is what brings about the change in taste of the water – albeit only slight.
So, how do we stop this from happening? Going back to the opening thought of why glass water carafe’s come with a glass to place on top; if the two main criteria are met, you stand a pretty good chance of keeping your water for days.
If you block the air and prevent it from interacting with the water, you stop the pH level changes in the water. Make sure you do this with a non-porous material (like glass or plastic) as even the smallest pore will allow for air to seep into the water and make it taste slightly different.
Aquazania – Perfectly Balanced Water
Aquazania takes the best possible care to ensure that water is purified to the highest possible level. It is then immediately bottled and sealed to prevent any acidification of the water.
We’d LOVE to hear your thoughts on this. If you have a glass of water next to your bed when you go to sleep, do you notice a major change in the taste if the water has been standing overnight? What do you think it tastes like? Share your thoughts with us.
