I he an issue with beer pouring foamy. I have done all the research on why it could be happening but I'm not sure any apply to me. My question is because of a consistent problem of beer leaking from the post when the coupler is hooked up I've stopped hooking it up other then when I need a pour. Could this potentiAlly be my foam problem, my thinking is maybe my system is treating every pour like a first pour because of the constant unhooking of liquid coupler? Any feedback would be appreciated. Thank you.
