I have an Apple beer in my secondary and the gravity is at1.000. Thier seems to be some bubbles coming up and making foam at the top, and when I put it in my beaker to take a hydro reading you could see the bubbles, Like carbonation in it? Is that carbonation? And if I add the 3/4 cup sugar and bottle is will this add to much carbonation and make the dredded beer bomb or will I be ok. :rockin:
