Best Ways to Store Water Long-Term Without Chemicals?

[CeruleanScribe]

Looking to build up my water reserves for long-term storage, but I’d really like to avoid chemical treatments if possible. I’ve come across a lot of info about using bleach or tablets, but I’m curious about the most reliable non-chemical methods people actually use and trust. I’ve got a few food-grade barrels and some glass containers, but not a ton of space, so smaller scale ideas are welcome.

Has anyone had success with thoroughly boiling, then sealing water

Boiling then pouring into sterilized glass jugs has worked for me, but be careful with storage temps—ever try rotating your supply every six months to keep it fresh?
