I'm in the second stage and transferred from the bucket to the carboy on 4/17. I'm using Potassium Metabisulfite solution in my airlock, 2 grams per gallon of water. Yesterday I slid the carboy out from under the table where I keep it to take a peek, then pushed it back. When I pushed on the carboy I noticed that I the airlock released a lot of air and then sucked the solution down into the wine! I'm assuming the pushing put too much pressure on the airlock. Maybe 1 tsp fell into the wine. I'm well before the stage where I'm supposed to be adding this stuff, and just hoping I haven't ruined anything! Again, it was a tsp of solution, but just need to hear from someone this will be ok.
