Portafilter FAQs
Portafilter FAQs
What is a Bottomless/Naked Portafilter?
A bottomless portafilter lets you see the espresso flow directly from the basket, offering a clear view of your extraction process. It's perfect for spotting channeling—an issue where water finds weak points in your coffee puck, rushing through unevenly and leading to a bitter, uneven shot.
With a bottomless portafilter, channeling shows up as erratic, splattery streams or gaps in the flow. Ideally, you want a smooth, honey-like stream that forms evenly from the basket. If you notice channeling, it’s a cue to adjust your grind, improve your tamp, or distribute the coffee grounds more evenly. It’s like a diagnostic tool for better shots!
Is a Bottomless Portafilter Better?
It depends on what you’re after! A bottomless portafilter is a great tool for dialing in your espresso. It gives you a clear view of how your shot’s pulling—any uneven flow or channeling is easy to spot.
Plus, it’s easier to clean, works with a wider range of basket sizes, and let’s be honest, it looks amazing in action!
That said, it’s less forgiving than a spouted portafilter if your technique’s off. If you love geeking out over your espresso and tweaking your grind and tamp, it’s definitely worth the upgrade.
Are Portafilter Baskets Universal?
No, portafilter baskets come in various sizes and designs to fit different machines, with common diameters being 58mm, 54mm, and 51mm.While compatibility is key, a bottomless portafilter offers more flexibility since it doesn’t have the fixed height of a spouted portafilter. Always check your machine's requirements to ensure the right fit.
