A pressurised basket is dual wall, with a the second wall providing a restriction, usually through a single pin hole, simulating the effect of the perfect Grind and Tamper, generally makes home espresso making that little bit more fool proof. A non-pressurised basket doesn't have the second wall and therefore the grind and tamper of the coffee has to be tight enough to provide the back pressure for the perfect extraction.

What is a pressurised basket?
Before I was using a standard Gaggia Classic PF and basket.
I can't actually recall if it had one or two spouts.
The handle snapped off it, hence the switch to bottomless.
