I've never had an issue with carbonation, but I made a batch of barleywine (partial all-grain brew). I added the usual amount of corn sugar--3/4 cup/5 gallon. It has been in a bottle since late June and it's scarcely carbonated.
The final reading revealed approximately 15% alcohol (I added honey to boost the alcohol). I also pitched champagne yeast in secondary. Does the high alcohol content interfere with carbonation? Should I have used more corn sugar to comensate?
Is it possible to use carbonation pellets at this stage to boost carbonation? The beer isn't supposed to be ready until around Christmas, but the lack of carbonation concerns me.
