Volvic 1.5L

You can’t get by without water.
You need it whether it’s cold or hot.
I find the ones with a long shelf life a bit scary, so I go with what’s available at the store
 

 
even so, it keeps until May 21, 2014…
(1.5L × 12 bottles) × 2 cases = 36L
Same amount stored at home and at the shop
