What should the psi be set to when using a nitro trap system?

When using a nitro trap system, the appropriate pressure setting is typically in the range of 30-40 psi. Nitro systems are designed to dispense beers, particularly stouts and other styles that benefit from nitrogen infusion, creating a creamier mouthfeel and a thicker head. The higher pressure required compared to standard CO2 systems allows for the correct dissolution of nitrogen into the beer, which ultimately contributes to the desired texture and carbonation level.

In a nitro trap setup, the balance between pressure and the beer's viscosity is crucial for ensuring proper delivery through the faucet, while preventing excessive foaming or flat pours. Lower psi settings, such as 10-15 or 20-25, may not provide sufficient pressure to properly push the beer through the lines. Similarly, excessively high settings like 40-50 psi can lead to over-carbonation, resulting in an undesirable pour and negatively impacting the beer’s quality. Therefore, 30-40 psi is recognized as the optimal range for achieving the best results in nitro systems.
