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

    1. "is this abnormal??"

      no;

      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.

      M.

      1. 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. 3-4 hours seems too quick, but I do buy glass bottled seltzer because it lasts longer unopened.

            1. 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....
