Most bartenders pour hundreds of draft beers a day, and so they are familiar with finicky tap handles and know how to tilt the glass just right to get that perfect head. The typical patron has likely never used a draft system before, and unless they have bartending experience, may have never poured their own beer either.
Standard tap handles can be opened slowly, and if not done properly can cause turbulence, similar to putting your thumb over the end of a hose, resulting in liquid agitation and a foamy beer. Bartenders know to fully open the tap handle, giving it the perfect stream of beer, but most of your customers won’t know this. So to give them a helping hand, we recommend using “Trigger Taps,” often referred to as On/Off Taps or Pass/Fail Taps. The purpose is to only allow a tap to be fully opened or fully closed, thereby reducing the possibility of a first-time self-pour customer accidentally pouring a glass full of foam.
