>>2180597I don't think they should taste metallic at all. I would be very suspicious if they did. Then again, everything is so filled with chink crap that looks good and usually works fine if you don't use it too much, which leads to good amazon reviews often. But again, I can easily vouch for nalgene steel bottles, they are great. Love mine, you can even boil water in it, just unscrew the lid first.
