We love those kombucha and Kevita bottles, though we don't get them much anymore now that we're brewing our own. Anyway, a trick I learned for removing the labels easier is to fill the bottle with boiling water and let it sit at least 15 minutes, then test it by peeling up a corner if it comes up easily without leaving a bunch of sticky residue, then it's ready. I've even had the entire label come off in one swipe!
