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. It also adds a beautiful aesthetic to the process of espresso extraction.
This bottomless portafilter is specifically designed to fit with Expobar espresso machines with a 58mm EB-61 group head. The look is very similar to the portafilters that come with Expobar machines, just without the spouts or bottom to the holder. The sturdy plastic handle can be removed and swapped if you so choose, and it comes with a free triple shot basket!

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!
