FAQ: Why Must Compressed Air Never Be Used To Serve Draft Beer?

Why must compressed air never be used to serve beer?

It is equally important to note that compressed air is never recommended as a gas source. The brewing industry invests millions of dollars in keeping air (oxygen) out of the keg package and, therefore, applying air pressure to the beer keg is detrimental to beer quality.

How long does it take Draught beer served using compressed air or a party pump to go bad?

Dispensing keg beer with a party pump (air): Any draft beer will remain fresh for no more than 8-12 hours. Air contains oxygen, and oxygen is an enemy of beer.

Is there air in beer?

The carbon dioxide that forms the bubbles in the head is produced during fermentation. The carbonation can occur before or after bottling the beer. If the beer continues fermenting in the bottle, then it naturally carbonates and the head is formed upon opening and/or pouring the beer.

When pouring a draft beer Why must you avoid imposing the faucet in the beer?

When pouring a draft beer, why must you avoid immersing the faucet in the beer? When pouring a beer, do not put the beer or the beer glass in contact with the beer faucet. If the glass was cold frosted, rinse it out before filling. The reason is simple: sanitation.

What gas goes in a keg?

When the tap is pulled to dispense beer, carbon dioxide flows into the pressurized beer keg, mixes and pushes the beer upward through the beer line and tap into your glass. The carbon dioxide compressed gas acts as the carbonation for the beer when it’s dispensed and allows the beer to taste its best.

Do you leave the CO2 on in a Kegerator?

To be on the safe side, we always recommend shutting off the CO2 when you do not have a keg hooked up. Technically speaking, the components of a kegerator will not allow CO2 passed the coupler when it is not hooked to a keg.

Which of the following is an appropriate reason to use a glass rinser prior to pouring a beer?

When you rinse a beer glass, it becomes more slippery, and there’s less friction when beer fills it. This allows a more even, clean pour and a substantial, fragrant head. As we’ve established before, beer foam is actually a good thing, because it carries a great deal of your beer’s aromas, and smelling is half the fun.

Can a keg be tapped twice?

The good news is yes, you can tap a keg twice —with some limitations, of course. In the event that you’re using a manual or O2 pump, you’ll unfortunately only get one tap out of your keg.

How long will a keg last once tapped?

How Long Does a Keg Stay Fresh? For most beers on tap, dispensed with CO2, the rule of thumb is that non-pasteurized beer will retain its freshness for 45-60 days, if proper pressure and temperature are maintained. If you are serving up pasteurized draft beer, the shelf life is around 90-120 days.

Why do beers have a head?

The head is a lid that prevents the carbonation from escaping too quickly; without it, that refreshing tingle wouldn’t last long at all. That same head also protects your beer against air. It forms an airy layer over your beer, preventing it from oxidising too quickly.

Does more foam mean less beer?

Apparently, this strategy is misguided. That halo of bubbles we’ve been told so adamantly to avoid may actually be beneficial. Foam, isn’t the enemy: a heavy topping of bubbles doesn’t damage the drinking experience—eventually those bubbles themselves fizzle into beer. So, get to pouring (and drinking!).

Why do Breweries rinse glasses?

First, rinsing the glass removes any unsee-able particles of dust or dirt, resulting in a properly “beer clean” glass. The carbonation in beer will cling to any speck of dirt, potential leftover beer residue, dishwasher cleaning chemicals, etc.

Should the tap touch the beer?

The tap faucet should never touch any part of the beer, and should definitely never become immersed in the beer itself. This is important, as to not transfer anything that might be on the outside of the tap into the beer you are pouring.
