Had my first two and it may be because I didn't leave enough headspace? Should I open and recvap the others, or will I just have gushers?
Or possibly conditioning temp too warm near a heat duct?
5 gal batch, used 5 oz sugar, made the fg, it was a kolsch, and stored at between 68-70 degrees but because it was near a heat duct temp could have gone up intermittently
