Sorry if this is a noob question. I have some 5-liter plastic bottles of drinking water. I normally just drink from the tap so I haven’t used any of that in about a year.

I know they’re probably still good to go for quite a while but I’m wondering - what do you all typically do? Do you use and replace the water so the stored one doesn’t taste stale?

Also, are there any good alternatives to storing drinking water in plastic? I’m trying to reduce my usage of plastic containers for long term food and liquid storage.
