  • Easy brew head cleaning with the Espazzola

    The cleanness of your espresso machine will highly influence the cup quality. Dirty water from the brew head will lead to a dirty cup, it’s as simple as that. There several ways to clean the brew head. Methods include back flushing and cleaning with a stiff-bristled stick. Although important, I have to admit that these…

  • Water, the weakest link in espresso brewing?

    I recently disconnected my Everpure Claris water filter because of a my house renovation. This left me with a problem. Where could I find filtered and softened water for my espresso machine?

Although the roast results looked fine…

  • Tiny cheap fluid bed: chaff collector and more testing

Secondly we wanted to configure the PID of the TC4/ Arduino to make it accurately execute pre defined roast profiles. Tije’s chaff…
