So I have just started drinking my second batch. First bottle seemed like had a bit too much carbonation for my tastes. So a few days later I opened a second bottle and poured into a glass. The glass immediately filled with foam and over flowed. I think i figured out my problem. Does this sound right? I made the batch from a kit which included the necessary amount of priming sugar. But I shorted the recipe by a gallon of water to get a bit more flavor out of it. So I'm thinking being a gallon short caused the amount of priming sugar to be too great, hence over carbing. No exploding bottles yet and its been 3 weeks though. Does that sound like a reasonable explanation for my all head pour?
