Has anybody used this machine that can post a review?
Nice to hear from another ROK (Presso) user. That was a nice summary the factors under your control with this machine.The ROK (Presso) is the wet shave of coffee IMHO. It's very easy to make awful coffee with one, and there's something deeply satisfying about pulling a godshot from this bare-bones hand lever machine. A large part of that satisfaction is due to the fact that along the road from your first battery-acid gusher to your first delicious, silky, crema-topped shot, you are forced to learn about the importance of roasting, grinding, freshness, bean variety, temperature and pressure. Sound familiar?
My shots usually come out like this guy's. When they don't, I usually know exactly why. BTW, I recommend the naked portafilter: better crema, great for honing grind & tamp.
