That's why I'm trying for smaller bottles of concentrate.
And you say no air exposure, so this means period right? So how can I mix the powder and water without exposure? Or do you just mean constant air exposure, so if I fill the bottle to the brim and there is just a tiny air bubble, is that good enough for a few months do you think?
Or is there some tool I'm missing that does this?
