What is considered the typical flow rate of beer in a draft system?

The typical flow rate of beer in a draft system is generally around 2 gallons per minute, which equates to approximately 2 ounces per second. This rate is important for ensuring that the beer is dispensed efficiently while maintaining its quality and carbonation.

A flow rate of 2 gallons per minute strikes a balance between speed and control, allowing bartenders to serve customers quickly without risking excessive foaming or spillage, which can occur if the beer is poured too quickly. This rate also helps maintain an ideal pour that results in a proper head, enhancing the drinking experience by showcasing the beer's aromas and flavors.

Flow rates that exceed this typical benchmark, such as 3 or 4 gallons per minute, could lead to issues such as over-carbonation and loss of flavor due to excessive agitation. Therefore, understanding and maintaining a flow rate of around 2 gallons per minute is crucial for quality draft beer service.
