Natural lemon flavor. There is no drink more basic and more thirst quenching that my lemon tea. You can drink it on cold days (and i hope you do) but i made this tea for those hot summer days when your mouth is ready to guzzle. If you are thirsty - put one of these in your hand, twist the top get your head cocked in the right position, lift and load. Slam some lemon tea into your system. It's a delicious coolant that will leave you with one thought - more! Enjoy. Not genuine without my signature. - Joe. Joe Tea online store. Also try Joe Chips. www.joetea.com. (hashtag)joetea.
