They will all keep in the fridge for several months if you do cook them now. It is good to keep the admix separate, so if you need more you can always redose!

Now that you know the feeling of vine-only effects, it will be easier to assess the strength of the admixture, too.

Another plus to brewing separately is you can drink the admixture about 20 minutes after the vine... I find it absorbs/activates more efficiently that way.
