Do you need to tamp pressurized portafilter?
Pressurized portafilters (generally) do not need tamping down. Brush the edges of the filter basket off so there are no stray coffee grounds to get into the threads of the brew head. I like to smooth the basket down with a light tamp to make sure the grounds are even within the basket.
How do I know if my portafilter is pressurized?
Okay, now let’s talk about pressurized portafilters, which are just different types of filter baskets. A pressurized basket has a false bottom, so it’s also known as a dual-wall basket. From the top, it has a grid of holes like any other filter basket.
Why are portafilters non-pressurized?
Non-pressurised baskets are the original style of basket used when brewing espresso. The difference here is that they do not contain the second wall, there is nothing else creating pressure when you brew your coffee other than the grind of the coffee and how hard you compress it when tamping.
Does grind size matter for Pressurised portafilter?

What is the difference between a Pressurised and non Pressurised portafilter?
When using a pressurised basket, the single hole creates a build up of pressure below the coffee which forces the espresso through. With a non-pressurised basket, there are multiple holes so the pressure is dependant on your grind size and tamp pressure.
Is a pressurized portafilter bad?
When using pressurized portafilter the coffee is being forced through a small hole which results in aeration, producing faux crema (foam). For these reasons, the coffee made with pressurized portafilter isn’t as good as the espresso made with a non-pressurized filter basket.
Are pressurized portafilters good?
Pressurized portafilters are better for beginners because they are more forgiving with respect to grind size and tamping. To better illustrate the benefits of a pressurized portafilter, we have to quickly review how a non-pressurized basket produces espresso.
