Try pouring it with the glass on a forty-five degree angle so the beer slides down the inside wall of the glass and doesn't splash in the bottom. A frosty cold glass helps too.
no the beer foam does not get u drunk
Drink the foam
160 12 ounce glasses to a standard 1/2 barrel.
"beer foam" or "head" is hydrophobic proteins in beer that make tiny bubbles when beer is poured. Breweries put lots of effort into making sure there beer has an appropriate amount of head for the style.
Root beer
It is foam and is often called the 'head' of the beer. The pattern it leaves on the glass as it is drunk is called lacing.
barm
Sounds like it.
May be due to the fact that the cup is not as smooth as glass. This allows for a much larger surface area for the dissolved gases to come out of solution. Increased surface area causing this can be seen in the nucleation (frosting) at the botom of modern lager glasses
About a finger's length. 1.5 inches! If too much foam is accumulated at the top of a beer, whoever you are serving it to is getting short-handed their alcohol.
This is a liquid who incorporated the gas, as the beer foam for example.
Beer is often referred to as suds. The primary reason is the foam that occurs on the top of a beer. The proteins in the beer create a higher surface tension that captures the CO2 and makes the 'head' of the beer.
