I searched everywhere and no luck. I am sure this has been asked, but I can't find it!

Is there any reason to NOT use water once it has been heated and cooled? I use bottled water in a Bonavita kettle because my tap water has issues. I like to add more water than needed so the kettle holds temp throughout the brew. Rather than pour out the left over, can I use I again the next day without negative impact on taste?
Previously heated (and especially previously boiled) water will lose a lot of its oxygen. If you want to save money on bottled water by reusing it, put it in a sealed bottle or jar and shake it vigorously. [Tip from my wife, the water treatment chemist.]

I once read from somewhere that oxygen "carries" the tastes to the tongue, or from another source: oxygen helps your tongue to taste the coffee (ie: your tongue needs oxygen to taste), or something like that anyhow. Thus you shouldn't boil the water...

Is there any thruth to that, I would not know. I only do what seems (or tastes) good to me. :P

All of the sudden a slew of info! Nice..

I will try the "re-oxygenation" method with shaking in a bottle. Doubt that's a word though!

The re-oxygenation process is so slow it won't recover overnight?

Well, the initial post asks about reusing water the next day - is the process of oxygen recovery so slow that it requires shaking the next day?

Yes. It is a very slow process.
