Hello, newbie here, got the deluxe kit for Christmas, brewed on Jan. 1st, bottled 2 weeks ago today. Smells great, taste is pretty good, but it just taste pretty flat. There is some carbonation present, just not a whole lot. I was actually worried about over carbonation because the sugar for bottle fermenting was for 5 gallons, and I ended up with only 4 gallons of beer at the end (guess I lost quiet a bit when I racked it). I feel like I followed the instructions so I am not sure if it just needs more time or what.
Of note, out of the 7 bottles that were tried yesterday (not all by me), all were pretty flat except one. This one seemed to be way over carbonated. When the cap was removed the beer volcanoed all over, and even after letting it settle you could not pour it without it turning to straight foam.
Any ideas on what to do now? Or how do I prevent this in the future?
