>Water is harder to store in the winter since it will freeze and burst containers if full Very true. I live in a hot climate and often freeze water bottles to take with me in the summer. A full sealed bottle, even a solid one like a Nalgene, will easily break when frozen. But I've found that leaving 10-15% of space empty and cracking the top ever so slightly prevents any sort of breaks. Leaving the bottle cracked open might not work so well for car storage though, unless it's secured upright.
