Brewing espresso with a bottomless portafilter (or naked portafilter) is not only addictive to watch but also reveals a lot about your extraction! Issues like sour espresso, too long brew times, or an uneven tamp become immediately visible with a bottomless portafilter.
Using a bottomless portafilter requires some attention and practice. You might not achieve a perfect extraction right away since this portafilter does not protect against splashing as a closed portafilter with a double spout does. However, it provides you with enough information to improve your technique!
Good to know about your bottomless portafilter
- Requires some basic knowledge: it’s helpful to master the basics of brewing espresso. Without the right setup, there can be a lot of splashing 😉
- Hygienic: no bottom where coffee grounds can get stuck, making cleaning easier
- Can be addictive: it’s very satisfying to achieve the perfect extraction!
There are handy barista tools for the bottomless portafilter to help prevent splashing. For example, our WDT tool and coffee distributor for evenly distributing the coffee, and a good tamper. Want to know more about using the bottomless portafilter? Read our blog (coming soon)!
