How is draft system balance achieved?

Draft system balance is achieved by balancing the applied pressure with the system's total resistance. This concept is essential in ensuring that beer is dispensed properly without excessive foaming or flatness.

In a draft system, pressure needs to be set in accordance with the resistance encountered by the beer as it travels through the lines from the keg to the tap. This resistance can come from factors such as line length, diameter, and any bends or fittings in the system. If the applied pressure is too high compared to the resistance, this can lead to over-carbonation and excessive foaming when the beer is poured. Conversely, if the pressure is too low, the beer may pour flat and unappealing.

By carefully balancing the applied pressure to match the total resistance, the technician ensures that the beer flows smoothly and maintains its intended carbonation level as it is served. This balance is critical for delivering a quality beer experience to the consumer.
