Want a better mouth feel and less channeling on your Gaggia Classic Pro? Then follow this simple tutorial for replacing the original 12.5 bar spring of the OPV to a 9, 6 or 5.5 bar spring. We take a look at the measured pressure of each spring, and determine the average flow rate in 4 separate extractions. Then we look at the results of the original 12 bar spring, as well as the 9 bar, 6.5bar and 5 bar springs.
