If you leave too little head space in the bottle, the beer will not properly
carbonate. I don't know why, but it won't.

I use a bottle filler and find when it is withdrawn, there is just the
right amount of headspace.

Keep it simple, keep it home made, relax, have a home brew. . . or something
like that.
