Foam explained This gas (carbon dioxide) is produced during the fermentation, bottling and kegging of beer, when the beer is pressurised and condensed into a space. That means when a beer is opened or poured into a glass, the gas bubbles rise to the top and create a foamy layer full of protein, yeast and hoppy residue.

You may wonder, is it good to have foam on a beer? The foam head doesn't only allow the carbonation to escape from the liquid. It also adds the aroma of the beer and the initial flavor to the first sip.

Similarly one may ask, does beer foam get you drunk? Over the years, studies have shown that, yes, bubbly booze can indeed help alcohol enter the bloodstream faster, leading to more rapid (but not overall higher levels of) intoxication.

Besides above, why you want head on your beer? Beers can range from highly effervescent in the case of many sours, or soft and creamy like a stout. The head of your beer also greatly helps to display a beer's aroma and prevent all of the carbonation from escaping and becoming flat.

Likewise, what is the correct way to pour a beer? The proper pour guarantees a better flavor experience. Hold your glass at 45 degrees in your hand and pour the beer at the mid-point of the glass. Tilt your glass upright as the beer is half-poured. Finish pouring beer into upright glass so there's ½-1 ½ inches of foam.


Do bubbles get you drunker faster?

Scientists have known since the 1920s (hello Gatsby) that bubbles intoxicate you faster than a flat beverage would, but that's not all. In 2007, scientists showed that drinking vodka mixed with something carbonated spikes your blood alcohol content to a higher level than just vodka.

How much foam should be on a beer?

Level the glass when half to two-thirds full and pour until full. This will achieve the proper amount of foam. The head should be one-half inch to 1 1/2 inches.

Does foam waste beer?

Getting as much beer out of the keg via your draft system is paramount to the bottom line and often, foam waste, is the culprit of diminished returns when it comes to beer sales. Foam is caused by two variables: temperature and pressure. Properly managing your beers' temperature can be complicated.
