FGMO/thymol mixture last over winter?

[dtwilliamson]

I am out of my FGMO/thymol mixture. If I make a new batch will it retain it's effectiveness over the winter for use next season? I would hate to waste a new batch for only a couple of uses since a 50 gram batch lasted me all season for 3 hives.

If you store it in a tightly covered Mason or canning jar in a dark place you can store it safely. I even store it this way during the summer to keep it fresh
