The two major types of filter baskets are pressurized and non-pressurized.Pressurized portafilters have one small hole in the bottom and use the tiny hole to build pressure to push espresso through. The non-pressurized baskets have small holes on both sides.
Now let’s dive deeper into the difference to make a better choice on which is best for you .
1. Pressurized Portafilter Baskets:
- These baskets have a built-in pressure release valve that helps create artificial pressure during the brewing process.
- The valve assists in compensating for inconsistencies in grind size or tamping pressure, making it more forgiving for beginners.
- Pressurized baskets often produce a crema layer on top of the espresso, even if the coffee is not freshly roasted or ground.
2. Non-Pressurized Portafilter Baskets:
- Non-pressurized baskets rely solely on the barista's skill to control the pressure and extraction process.
- They require a consistent grind size, proper tamping technique, and precise brewing parameters to achieve a balanced and flavorful shot.
- Non-pressurized baskets are favored by experienced baristas as they provide more control over the brewing variables, resulting in a more nuanced and authentic espresso flavor.
In summary, pressurized baskets offer convenience and forgiveness for beginners, while non-pressurized baskets demand skill and precision but allow for a higher level of customization and quality in the espresso shot.
