A guy never wants less head ... except when it comes to his beer.

The object (or so we've thought) when pouring a beer, is to tilt the glass and prevent as much foam (or head) on the beer as possible.

But that's not the case as it shows in the video. If you pour a beer with almost no foam, that means you've trapped all the CO2 in the glass. When those bubbles pop, the gas expands. Then, when you drink that beer, you're drinking that CO2. So if you eat some food, when what you ate hits your stomach, it's going to hit that CO2 in your stomach causing you to feel bloated.

Ideally, you're looking at about two-thirds liquid, and one-third foam. It'll still have plenty of bubbles and it won't taste flat.

So, while it might seem weird, and look like you're wasting beer by pouring it vigorously and creating a lot of foam, you are, in fact, pouring it properly to prevent all that CO2 from taking up space in your stomach, and helping you get all the sweet flavors of the malt and the bitterness of the hops out of your beer. And yes, all that foam, will eventually settle down, back into beer.

Cheers!
