I received a comment from a Judge that my Helles was slightly oxidized. I transfer from my Carboy to the corney by forcing CO2 into the carboy using a hood with and racking cane. Similar the sterile siphon shown on B3, but just with CO2 at a low PSI. The only thing I can think is that I didn't purge the keg enough and it picked up O2 during the transfer stage or when I counter pressure filled the bottles. I cap on foam so who knows. I'm not going to put to much thought into it. It was just one comment.
But it got me thing to how I could do a closed system transfer. I thought it may be easy to go from the racking cane directly to the outlet side of the corney avoiding any opening of the keg. As long as the keg was sanitized and flushed with CO2, I'd be set. No oxidation or contamination.
Anybody have a set up like this? Got Pics?
