Beer foam is reasonable

If you’ve ever tried your hand at bartending only to realise you are unable to pour a beer without forming a head of foam - you are in luck.

A beer sommelier has revealed to Business Insider the proper way to pour a beer - and it turns out that a head of foam is actually a good thing when enjoying a nice cold one.

And beer bloat is actually the result of pouring a beer incorrectly - or pouring a beer with minimal foam.

According to Max, carbon dioxide that has not been released into a glass when pouring a beer, which is what happens when you pour beer into a tilted glass slowly, has a disastrous effect when it settles in your stomach.

This slow-pour means the CO2 has nowhere to go - which leads to bloating when the liquid is disturbed in your stomach and the remaining carbon dioxide is released - especially once you add food to the mixture.

The solution? Pouring a beer down the side of a glass with vigour.

This method of pouring a beer ensures that the CO2 is broken out into the glass - meaning the bloating that occurs when drinking a beer that was not poured properly doesn’t happen.

So before you try to send back a beer for having too much foam, remember that the foam is actually protecting you from feeling full and uncomfortable.

And the foam is where “you will taste the sweetness of the malt and the bitterness of the hops” as well as protect the integrity of the beer aroma.
