This is what I came up with
Floss holders (on clearance) and hair elastics.
I write the name of the flavor on the blank side, loop them onto a hair elastic and this slip them on the bottles.
After someone takes a bottle from the fridge the tag goes into a baggie I have stuck to the door with a magnet.
No more confusion and everyone knows what they are getting. The labels can be used again and again, so I won't have to make them up for each batch. Also it was cheap and easy. maybe not something to look for in a girlfriend, but with craft projects I'm all about the cheap and easy.
