Profitec Flow Control completes Espresso Machine
I can't imagine buying an Espresso Machine without Flow Control. The dark roast beans I bought and dialed in remained harsh and bitter in the cup. That's it. That's all you get. Instead, I lowered the temp on the PID and lowered the last 15s of flow to about half flow rate. Result was a rich, smooth, non-bitter 50ml shot. Fabulous!
