A big shot beer expert at Anheuser-Busch has made it his life's mission to teach people how to drink beer, and he is warning people that pouring beer wrong could cause stomach aches.
Max Bakker explains that when you pour beer slowly and carefully, the carbon dioxide gets trapped in the beer and then all those bubbles go to your stomach, causing you to get bloated.
Amazingly, the carbon dioxide trapped in the beer can expand to more than two times the actual volume of the beer.
So, the trick is to start with a tilted glass and pour vigorously, which will create a bunch of foam. The foam ends up making the beer taste better. And, because the foam doesn't end up in your belly, you feel better while chugging your brew -- a win-win. (Daily Mail)
