Had some seltzer water in the fridge (canned) and decided to brew some tea with it. I chose a green tea because I figured boiling the water would boil all the carbonation out of it. Even with the water only getting to about 180 degrees most of the carbonation left. Next time I'll have to stop at about 160 and see if that helps.
The overall flavor was mostly the same but lighter. Not bad. I'll give it a try with a lower temp next time.
