Iced Tea prep

I'm trying to "meal prep" iced tea. I like to start my day with unsweetened iced tea at work, but im tired of the same old gold peak or whatever. How long would iced tea last if refrigerated in bottles? Id like to make maybe a dozen 12 to 16 oz bottles for the week. If anyone has done this before, any recommedations on bottles? Maybe something with wide mouth and i can cold brew one or two tea bags per bottle. Any insight is appreciated!
