What do you use to mark natural rind cheese. Food colour and a brush? Or can one buy special markers containing food colour?
Anything that you write on the wheel will soon be overcome by mold (both covered up by mold, and eaten by mold). You either need to keep the cheese on a numbered board/mat, or use numbered stencils that are placed on the cheese turning the final turn in the press. Cut numbers out of a piece of plastic (like a flexible cutting board) and lay them on top of the wheel and then press for an hour+.
We used red food colouring on a bamboo skewer on a Parmesan, and then oiled the rind to prevent mold growth, and it seemed to work OK.... If you are growing mold on it, Bantams suggestions would seem logical....

Thanks, tried food colour on Romano, so far a bit faded but no mould
