    Interesting, I've just started drinking seltzer regularly and noticed that it was flat the next day in the fridge, which surprised me.

      "is this abnormal??"


      Maybe the cap was leaking "air", it sometime happen when the seal is first brake open when opening the bottle; water might not leak, but air and gas will.

      It could also be depended on the "quality" of the carbonation process; or if it was natural carbonation.

      That's why I buy small bottles instead of large ones.

        3-4 *hours*? I have to think you're doing something wrong (like leaving it open for a long time before putting the cap back on?) I buy seltzer in 1-liter bottles and it last 3-4 days.

        You could always try getting a SodaStream. Then you can re-charge your flat water whenever you like.

          or as goofy-looking as they are, those vacuum pump thingies that pump air into the bottle to help extend the life of the bubbles.

            +1. Mine last 5-7 days.

            3-4 hours seems too quick, but I do buy glass bottled seltzer because it lasts longer unopened.

              Yes. Mine lasts at least 3-4 days (sometimes even 7 days). The carbonation gradually fades.

              Don't store opened seltzer bottles on their side - you are creating an ellipse with more surface area than a circle, so greater loss of carbonation.

              And choose a good maker - not all seltzer is equally well carbonated....

                I dunno, I'm really picky about how flat things go especially it seems in plastic bottles. I consider plastic bottles to be effectively one-time use, like cans. A few hours seems about fine, but by the next day it's always too nasty. Doesn't matter if it's Coke, seltzer, whatever. Doesn't matter if it's 2-liter, 1-liter, 20oz bottle, 12oz bottle, just doesn't matter. So it could be just a matter of how picky you are about the carbonation. Or maybe it really is inferior carbonation, I don't know, but I know it's not just cheap seltzer that does it. Name-brand sodas are problematic as well, at least for me.

                Been a while since I bought anything fizzy in a glass bottle that wasn't a single serving (Boylan's ginger ale has been a recent fave, but that's just 12oz bottles), so I don't really know how much that might help.

                Been thinking about SodaStream again recently though as we've ramped up purchase of plain club soda/seltzer. Been buying it in cans for the moment. Been beginning a lot of sentences with "been".... ;-)
