So stainless steel becomes the obvious choice for people who want a rugged, portable and lightweight bottle, too. (Stainless steel is much lighter than glass for the same sized container.)
6.0 L Imperial: Equivalent to eight standard 750 ml bottles or two Double Magnums. In sparkling wines this volume is referred to as a Methuselah.
The drawbacks are that you can’t tell how much water you have remaining in the stainless steel bottle, and you can’t squeeze it to get more water out. Instead, you tip the bottle up and drink the water coming out of the nozzle.
It took us a while to find the right stainless steel bottle to carry in our . We wanted one that had a comfortable and well-functioning nozzle that lets air into the bottle to equalize air pressure as you drink (not all bottles do this).
