I’ve always heard it’s best to pour your beer in a glass and thanks to this video, I now know why.

Max Bakker is a beer sommelier (aka expert) who works for Anheuser-Busch InBev. In the above video, he explains why you may experience stomach issues when drinking beer. It could be that you’re going about things all wrong.

If your goal when pouring a beer is to produce zero foam, you’re not releasing the CO2 in the glass. Instead, the CO2 is being released in your stomach, causing discomfort – especially while eating. So next time, pour it with vigor and break the CO2 out.
