Hacked a moka pot to create this amazing little espresso machine, powered by a bicycle track pump! No more burned, bitter coffee – just great flavour using this innovative high pressure brewing technique!
I replaced the moka pot’s pressure relief valve with a Schrader valve from eBay. Luckily the threads matched perfectly and it was able to create a good seal, allowing it to reach a pressure of more than 100psi!
The resulting coffee has great flavour and no bitterness, similar to espresso brewed on high end machines.
