So I've kegged my last batch, was an 'imperial IPA', and will drink it in my house with some few friends. It's a borrowed 19L cornelius keg, and I think that we cannot drain it completely. Since I've to give it back to the owner I was thinking about fill some bottles. And them I've think about let my friends fill bottles when we're drinking, directly from tap. I will use a DIY jockey box with ~15m coil and a flow controled faucet, with 'push-back creamer' function, somewhat like that. I use standard crown type metal caps and my capper is like this.
So, there is a way to do this without anything else, or I strictly need at least a thing like this BMBF?
