Yea ive had it for about a week and a half and now its watery so maybe its the juice and the 18mg backups i have arent great either cherry flavor tastes like if you got axe spray in ur mouth by accident
It shouldnt have gone off that quick, has it been in the sun or the heat as both heat and sun will cause juices to go off very quickly.
The cherry may just need a little steeping if its a chemical/alcohol kind of perfumy (if you know what I mean,lol), taste to it. I would definatly try steeping it. I've known very bad juices taste rather good after a good steep.
