2 Reasons Why Grind Size Matters For Pressurized Portafilters


The topic of grind size in a portafilter is a contentious subject, so we thought we would look into it a little deeper to find out exactly what the truth is.

The grind size of coffee beans does not matter for pressurized portafilters. But there are different schools of thought on this topic. Some people say that the grind size is important for pressurized portafilters because it may create a larger energy density at the bottom of the filter puck, extracting more quickly.

However, other people say that this is not true because extractions are pressure-driven, and all extractions will be limited by how much pressure is being applied to them.

We have had hundreds of questions about pressurized portafilters, which we have tried to answer in this article. So stick around until the end to find out our most frequently asked question.

How Does A Pressurized Portafilter Work?

A pressurized portafilter works by applying pressure to the ground coffee with water heated to the appropriate temperature. It provides a balance between air pressure, water temperature, and the weight-loaded piston pump design. 

It has an interior side chamber holding air pressure created by heating water in the boiler. When the piston moves up and down inside the chamber, it forces hot water under high pressure through finely-ground coffee in the filter basket.

Do You Tamp A Pressurized Portafilter?

Many will say that you do tamp a pressurized portafilter. The coils of the coffee inside the portafilter need to be compressed to produce an even extraction. The pressure of the water entering through the group head will help with this process.

Others will say that you don’t tamp a pressurized portafilter. Even if you compress it, it won’t change anything because the water pressure is enough to extract even without any compression. In addition, they believe that tamping releases heat and flavor from the coffee before it reaches your cup, which isn’t good for espresso drinks.

The truth is that both methods are valid and depend on various factors such as technique, grind size, machine type, etc.

What Is The Difference Between A Pressurized And Non-Pressurized Basket?

There are two types of coffee baskets, the pressurized and the non-pressurized. There are many benefits to both, but they each serve different purposes. The pressurized coffee basket is designed to keep the water at a constant temperature for brewing, while the non-pressurized basket lets the water boil away while brewing to create pressure.

The benefit of using a pressurized basket is that it helps maintain a constant temperature while brewing. This helps achieve an even extraction which in turn creates a better-tasting cup of coffee. 

The disadvantage is that it can be difficult to clean because it traps grounds in its mesh filter and requires more attention during cleaning than regular baskets do.

How Do I Know If My Portafilter Is Pressurized?

There are several ways to determine if your portafilter is pressurized, but here are two you can use right away.

1) The most reliable way to find out if your portafilter is pressurized is by checking the pressure gauge on your espresso machine. If the reading on the gauge is over 10 bar, then your portafilter has been pressurized.

2) Another way to tell if your portafilter has been pressurized would be looking at how much coffee grounds are in it, as well as how long they have been sitting there. If you are using a double spouted filter, then there should be more grounds

Why Is Espresso Pressurized?

Espresso is pressurized because the pressure pushes the water through a group of coffee grinds. This creates a richer and stronger flavor.

The pressure raises the boiling point of the water, meaning it becomes hotter at a higher pressure. The increased temperature also boils off more water from the coffee grounds, maximizing their flavor extraction from these grounds.

Can I Use A Non-Pressurized Portafilter?

You may be able to use a non-pressurized portafilter if you have a compressed coil spring on the bottom so that the weight of the coffee puck is not resting on the rubber gasket. The more tightly packed coffee puck will help ensure water doesn’t leak through the bottom of the filter basket and into your espresso machine.

The problem with non-pressurized portafilters is that they don’t have an airtight seal, which means that the grounds can seep into the coffee. Non-pressurized portafilters are good for brewing decaffeinated coffee or tea, but they are not advisable for espresso. They also require more force to tamp because of their loose fit. 

Is A Pressurized Portafilter Bad For Your Coffee?

A pressurized portafilter is a type of espresso machine designed to offer increased pressure for brewing.

Advantages: Increased pressure can provide stronger extraction, meaning that more flavor can be extracted from coffee grounds into the espresso. It also helps to create crema on the top of the espresso – this is often used as a signifier of how well-extracted your espresso shot was.

Pressurized portafilters are popular because they do not require any specialized equipment to operate them. In addition, they are compatible with all kinds of grinders, tampers, and filters which makes them very versatile.

Disadvantages: They are more expensive than other types of portafilters like semi-automatic or piston portafilters.

What Does A Pressurized Basket Look Like?

A pressurized coffee basket is a container that holds the coffee grounds and water before it goes through the filter. The container has a lid and a plastic mesh with holes in it to allow the hot water to seep through and extract flavor from the grounds. The basket is typically made of steel or aluminum, but there are also models made of stainless steel, copper, ceramic, or plastic. Some have a filter inside them as well.

How Do You Clean A Pressurized Portafilter Basket?

To clean a pressurized portafilter basket you should first remove the portafilter from the espresso machine and use a brush to scrub off any oils or coffee grounds that might be leftover. Then soak it in a container of water for around 10 minutes.

Next, the user should take a brush and scrub off any dried coffee grounds. Finally, he or she should rinse it with hot water and dry it with a kitchen towel. The mechanism for this is pretty much the same as a regular portafilter. You want to make sure you have a firm grip on it, and you generally
