Converting 10 gal keg to primary

sorry if this has been posted, but the old posts i found had to do more with conditioning out of kegs.

i’d like to use a 10 gal stainless keg as a primary fermenter. instead of drilling a hole in the lid to put in a stopper and airlock, can’t i just remove the liquid post and put a stopper/airlock in there? any idea as to what size stopper i should try? thanks

The gas in post works well…

Put a gas disconnect on the keg. Run some tubing from the disconnect into a quart jar of sanitizer/vodka.

I thought NB sold a disconnect with an airlock fitted to it. I can’t find it now. But here is a home build on the idea.

This site mentions removing the post and finding a grommet with a 3/8 opening to fit the opening on the keg. It doesn’t mention what the OD of the ring would be. So I guess take your keg and an airlock to the old style hardware store and see what fits.

That’s what I do.

Thanks Nighthawk. I guess I somehow deleted the rest of my post last night. But, thats direction I was headed.

+1. A wider tubing will decrease the chance of sucking liquid up into the keg. (Or leave the end out of the liquid until active fermentation begins.)
