I use freezer tape or golf grip tape, wrapped at least one full turn around the bottle with at least some overlap. The golf grip tape works better than the freezer tape because the freezer tape tends to slide on the bottle, regardless of whether the bottle is glass or plastic.
I use Sharpies, but all that I write is a 2-digit number on the label (which will become a 3-digit number sometime in the relatively near future. I'm up to 83 at present). Since the tape is wrapped all the way around each bottle, there's plenty of room to cross out the previous number and reuse many times before having to replace the tape.
On my computer, I've maintained a DIY mixing log for over 5 years which contains all of the details for each number.
