I have unlocked master mode, and I have just completed a second brew. I would like to lower the serving pressure to experiment with lower foam pours.
Is it actually possible to do this at this stage of the process? I can think of no reason why "change CO2 pressure" should not be available, but I cannot find any way to do so.
Is this something that can only be set before starting a brew? That doesn't make any sense, so I hope I am wrong...
