@RedDenver I can't burp on command very well at all but then again I've never really seen the purpose in trying to burp when I don't need to. There's no problem when it's required though.

Only when drinking beer.

I used to be able to. Like @ZRod said, just swallow air and belch it out.  I think that's a question of ab strength, because I just tried it for the first time in 20 years and I couldn't do it.
