Or, at least, label every bottle in large, easy to read letters. Gaff tape or duct tape and a magic marker is all you need. Use colored markers if you like. This is what I do. I also label my beakers to prevent any mix-ups while processing.

Wrap the tape all the way around the bottle and repeat the label so you can read it from any angle.

Make the letters big enough that you can read them in the dark.
