I'm drinking a current batch of a mild London Ale. Was only my second batch. I've had about 10 bottles that were fantastic, perfectly carbonated, etc. I've had about 4 that were WAY over-carbonated, so I'm thinking somehow the sugar might not have gotten distributed well enough?
I took 5/8 cup priming sugar, dissolved into 1/2 cup boiling water, and poured into the carboy with a sanitized funnel. Then when I put in the racking cane tried to stir it. I tried not to stir too aggressively to stir up the sediment.
Maybe I'm answering my own question here, do I need to transfer to another carboy or bucket for bottling, and add sugar when 1/2 full?
