I do not normally bottle beers unless I am entering a competition or sending a bottle or two to friends and relatives. I have been tasked to brew and bottle for a friend's wedding party, which is in three and a half weeks. The party is at a bar and they don't allow outside kegs, so these bottles will be given away to the participants, assuming at the end of the afternoon. Right now the ten gallons of beer is cold crashing and will be dry hopped cold for a few days. I plan to fill bottles this weekend, but I always lose some carbonation when I bottle from a carbed keg.
The questions I have are, rather than use a beer gun and try to fill four cases of 12 ounce bottles with carbonated beer, should I just add sugar to the kegs and only force carb the kegs up slightly? Will three weeks be enough time?
