Bottomless or 'naked' portafilters were originally designed as a training tool. Without the obstruction of a spout, it becomes much easier to see what's happening as the water passes through the tamped coffee. This is particularly helpful for spotting channeling - a frequent culprit when it comes to suboptimal extractions. In recent years they've also become popular because of their aesthetics. If you get your tamping and distribution just right, the extraction looks stunning!
This bottomless portafilter is an original Rocket Espresso part. It should make the perfect companion to any Rocket espresso machine, whether it's as a training tool, or simply for the beautiful look!

A note on distribution, channelling & spraying
Using a bottomless or naked portafilter can be a humbling experience. If your tamp and distribution aren't exactly right, not only can you get a wonky extraction, you may even experience some spray. That doesn't mean anything is wrong with your portafilter. It, unfortunately, means that there's something wrong with your puck preparation.
Those good old spouts that your original portafilter came with mask those issues, for better or for worse, but now that you've upgraded, you're seeing the naked truth, and sometimes it ain't pretty.
How do you fix it, you may be wondering? Well, it's all about even distribution and an even tamp. You can achieve this without any extra accessories, but we have some tools that might help with the distribution part at least. These will help you make your extraction Instagram-video-worthy and your espresso exceptionally tasty:
For even tamping, there's nothing quite like a Puqpress!
