I have recently ran out of Carbonation Drops that I have exclusively used in the past. I decided to use sugar and put a heaping teaspoon of sugar in every bottle. Two unexpected things happened, the beer did not carbonate totally and the beer tasted really sweet.
What can be done to avoid this in the future. I have a keg system now, so I do not expect to ever use sugar to carbonate again, unless I can control the taste or use the drops.
What can be done to make sure the sugar does not affect the taste and will carbonate the brew?
