I brewed two beers yesterday and I'm moving the blowoff to their serving kegs for purging. I'd like to keg-condition these two beers. They currently are sitting under slight pressure, with some Starsan in them after being rinsed. My plan (for each) is to dissolve about 4oz of sugar in some hot ware, let it cool, and pour into the serving keg, then reseal, move the blowoff to the liquid out, and put the gas in on either a blowoff tube or sounding valve. Will I have any problem with the sugar water solution sitting in each keg (at room temp) while fermentation is happening in my FVs?
