I've read somewhere that you're supposed to put vodka or sanitized solution in your airlock. I don't drink vodka, so I don't have any on hand. So I put a solution of starsan in my airlock. But then i was thinking: what if some of this solution gets into my wine? I quickly poured it out and just put in plain old water.
Am I being too careful here? What's the worst that could happen if I get 1 ounce of starsan in 5 gallons of water solution in my wine?
