The hardest part is waiting for frags to fill in.

I missed your dosing plans, are you working in vinegar and sugar into the fray or just sticking with vodka for now? When I was reading into this some of the suggestions involved using those as well. I was wondering if a person could just mix in a little sugar and vinegar into the vodka and just dose it all at once or would that degrade the vodka somehow.
