Most of my bottles are the EZ-cap, swing top type Like this. My question is, has anyone ever found an easy way to mark these bottles so they can tell different brews apart? With normal bottle caps I can just mark the cap with a sharpie but I don't want to do that with these swing top bottles. Labels won't work because I often put them in an ice chest and the water will just wash them off. Help!
