Questions for those using vodka and water together to taper

If I made a batch of 5 days worth, would it go bad?

I don't need to refrigerate do I?

Thanks

We don’t really know how long your suspension will last so it’s good to make small batches and I believe most members will refrigerate it, but again, we don’t have enough scientific research to know for sure. 

OK I will experiment, I won't refrigerate due to evaporation.

I think a batch would last 5 days, as vodka stays ok for ever I think.

 

Do you cover the mixture to avoid evaporation?
