What is the proper way to pour a beer?


When you pour the beer slowly down the side of a tilted glass, a smaller head is formed, and more CO2 remains dissolved in the beer. If you hold the glass upright and pour straight into the glass, more gas is released, and a larger head will form. Real a cionados will insist that different beers have different ideal pours. Generally, pour an ale so that it has about half an inch of head, lagers with a larger one, and allow a wheat beer to have a big, pillowy head.

What causes beer bubbles?

Beer bubbles/fizz/carbonation is caused by the action of yeast. When the yeast eat the sugars in beer, they produce a by-product of carbon dioxide (CO2) and alcohol. Carbon dioxide is a gas that dissolves in the liquid and remains that way under pressure until you open the beer. You can further release the CO2 by pouring beer into a glass. When you do this, the CO2 that is released during the pour carries some of the aroma with it.
