Looking for advice.
I use a 5 gallon CO2 purged corny keg for secondary fermentation. I cut the dip tube about a half an inch short, and inserted the tube into a hop filter that I drilled a hole in. I also have a spunding valve as an airlock. When it is ready, I cold crash and transfer under pressure to a purged serving keg.
My question is - can I also prime with priming sugar at this stage?
All thoughts appreciated
