Subject: Pressurized portafilter- Tamp or no tamp?
 

I'm planning to buy the Delonghi EC702 Semi-Auto pump espresso machine. It comes with a built In tamper which means I tamp upwards. I planned to buy an external tamper (Espro calibrated tamper) Do I have to tamp espresso If I'm using a pressuzied portafilter? If so and I can use an external tamper, do I still need to use 30 pounds of pressure?

It doesn't really matter, because a pressurized portafilter is for people who don't want to be bothered with correct grinding and tamping. You get seemingly good results without craftsmanship.

In a pressurized PF there's usually a plastic or rubber device or a double wall located below the actual filter basket that forces the coffee to pass through small openings, thus generating pressure. That way it creates foamed coffee (bubbles made of air) that has nothing to do with real crema, which is an emulsion of water and aromatic oils that forms tiny bubbles around carbon dioxide released from the coffee beans during extraction when water is pressed through finely ground fresh coffee at around 9 bar and the right temperature. Since extraction has already taken place when pressure develops in a pressurized portafilter, no crema can arise. It may look like it, but it certainly doesn't taste like it. It's a fake. You can taste the difference.
