I'm brand new to homebrewing. Call me unconventional, but I skipped bottles/corny and went straight to sanke kegs. If you have a commercial kegerator system I don't see the point of corny kegs. If I had one I would use it as a reservoir help to clean the sanke. There's really no need to open sanke kegs and its not that hard to open them anyway(it's just a retaining ring). 180° Pbw and star san handle the cleaning. You can use co2, a garden sprayer, water pump, or vacuum pump to move the solutions in and out through a coupler with the one ways removed... Using as directed...Agitate them... Voila, clean/purged kegs. I use a two hole carboy cap with a ss racking cane in one hole and and plumb co2 to the other. Then I rack from the glass carboy directly into the keg, virtually eliminating any chance of contamination or oxygenation. I bought mine for $90 brand new for a 1/6bbl. And you can get 1/4, 1/3, or 1/2bbl for not much more. (Or $20 if you are a damn thief) The used corny was about $65 plus fittings. So really, why the corny?
Homebrew shop told me I would have to use a $10000 automatic commercial keg sanitizing system. I think this works just fine.
Thoughts?
