I've been kegging for about 5 years now and for the most part, if I need bottles, I just fill a couple from my already carbonated keg. However, a month ago, we brewed up a batch of IPA and we had just under 6 gallons at packaging time. I decided that we'd put the remaining 1 gallon into bottles and carbonate with the Coopers sugar tabs. The beer has been in bottles for a month at room temp and there is zero carbonation. It occurred to me that I fined the beer with gelatin before kegging. Did the gelatin remove ALL the yeast and thus, no carbonation? If so, what is the best method for adding a little yeast to the bottles? How much per bottle? They are 22 oz bottles.
