Interesting grinder particle size analysis

Regardless of grinder, you always see an increase in percentage of fines as you go to a finer grind setting. When you change other factors (rpm or bean load) it's not yet as clear. E.g., ...

Advice on super-automatic vs. manual espresso machine

Espresso at the touch of a button, but the quality was simply unacceptable. I've used Jura and Gaggia superautos, and they were no be...

Decent Espresso news
