keg hopping is frustrating to me and I think I may have developed a solution. I normally fill my kegs with sanitizer and push out with CO2, hopefully getting an oxygen free keg. The only problem is, popping the keg open to toss in a bag of dry hops probably introduces a ton of 02. What if I took a keg that was clean and sanitized, added a sack of dry hops to in, then during primary fermentation connected the airlock to my outpost on my keg so that the ensuing fermentation would purge the keg of 02 as it was replaced with c02 from fermentation. I'd have a spunding valve set to 1 or 2 psi on the inpost to allow 02 to escape.
Would this in theory leave me with an 02 free keg with dry hops in it that I could then do a closed transfer?
