Remember the show “Cheers”? The bartender wipes each glass with a bar towel, leading us to believe that’s how beer glasses are supposed to be cleaned. But, this is wrong. Mostly because of the dirt and grime that gathers on the towel after wiping down the bar top transfers to the beer glass.
Bars, restaurants, breweries and beer distribution centers use dispense gas to help pump beverages through beer gas lines or to carbonate fizzy drinks on site. The dispense gas, which can be either carbon dioxide (CO₂) or a nitrogen (N₂) mix, has numerous functions, such as improving the taste of the beverage, keeping the contents of the keg sterile, and helping to maintain the draft beer equipment.
