This is a 10 gallon batch of English Bitter that I brewed yesterday(01-05-2012). One batch split between 2-6.5 gallon fermenters. Both were pitched from the same starter and aerated and sealed exactly the same.
As you can see, one is bubbling away and the other hasn't produced a single bubble. Both will ferment exactly the same and the end result will be close if not exactly the same.
In closing, if you did all or most everything right, you will make beer. Bubbles are exciting(to a point) but they really don't mean anything.
