What is the recommended psi for a jockey box?

The correct recommendation for the psi (pounds per square inch) in a jockey box is typically within the range of 30-35 psi. This pressure range is optimal for ensuring that the beer is dispensed properly while maintaining carbonation levels. When the pressure is set within this range, it provides a good balance between sufficient flow rate and maintaining the quality of the beer.

In contrast, pressures that are significantly lower, like the 10-15 psi range, may result in flat beer due to insufficient carbonation being maintained as it travels through the system. On the other hand, higher pressures, such as those in the range of 35-40 psi, can lead to over-carbonation or excessive foaming, which can undermine the serving experience by causing more waste and difficulty in pouring.

Thus, the choice of 30-35 psi is considered optimal for the effective operation of a jockey box, enabling the delivery of refreshing and well-carbonated beer.
