There’s something strange about this tea that I can’t put my finger on. It’s not the carbonation since I’m a big fan of carbonated drinks and I carbonate all kinds of drinks on my own (homebrewer). I’m generally not sensitive in any way to artificial sweeteners or flavors but something in this tea doesn’t sit right with me. I’ve had it a few times now and every time it seems to give me a minor stomach ache. The regular Lipton Green Tea bottles w/o CO2 are good for what they are but I wouldn’t recommend this stuff.
