JHCCoffee as Jake alluded to, fortunately the goal is to make espresso and not pucks. That said, most people prefer drier pucks because whilst there doesn’t seem to be any effect on the espresso, drier pucks are less messy.
I’ve had both the original decent set up. And then they sworksdesign kit. And now the latest decent group head kit. I switched to the latter for two reasons.
I like to keep my Decent current with the latest updates and John’s commitment to ensuring that every owner has the option, via upgrades, to have the equivalent of the current latest model and therefore avoiding obsolescence, makes this possible. And he keeps these upgrades relatively affordable.
The amount of testing that went into the design of the latest grouphead upgrade was such that I wasn’t tempted to second guess and go with alternatives.
Hope that helps.
