I made solar tea but it was larger then my old gallon container. It was 6 qrts.
I put in about 14 tea bags and the I bought at SAMs in the coffee isle, Unsweetened Razzberry flavor liquid. It does need sweetening. or else over ICE.

I will look for the substitute but true nutra stuff in the meantime.
I like this container, it has the spout on it and I use to use it for family cookouts for Ice tea. Also water in the fridge in the summer.

I have been drinking too much diet pepsi and toooooo much sweet tea.
