Quick Overview

We do not modify stainless steel portafilters!

Product description

Okay, so you have an extra 58mm portafilter and you want to go bottomless, a great idea. It will without a doubt improve your espresso shot consistency and quality. How you might ask? With a bottomless portafilter the user knows right away if something is "off" (it can get messy), and can adjust grind settings and tamping method to correct any issues. Years ago some Barista's from Zoka Coffee in Seattle were playing around with an idea, and thus the creation of the Bottomless Portafilter! Before that according to espresso legend a bottomless portafilter was created at ESI/La Marzocco to find out what was happening with the filter basket at extraction.

Feel free to send us your new or used portafilter and we will do the modification and send it back to you within 72 hours after we receive it!

Hang on, how does this all work?

First, you must place your order by adding this item to your cart. Then, send the portafilter, 58mm only, with no basket or spring, to Espresso Parts 4315 Lacey Blvd SE, Lacey WA 98503. (Sorry, we cannot/do not modify stainless steel portafilters!) Include in the package a copy of the order confirmation you receive in your email inbox. You may also want to reference your order number on the shipping label or write it on the outside of the package. The sooner you ship it to us, the sooner we can get it back to you!

Please insure your item and if sent via the postal service please use delivery confirmation. We will ship your portafilter back via Fed Ex. When you order you will be charged your freight costs upfront.

Note: Due to the fact that this is a modification to a manufactured part, there may be some minor scuffing of the interior sides of the portafilter. This is cosmetic only and will not effect the function. No external scuffing occurs during the process.

Least costly solution Review by Chris
Item Rating

Less expensive than buying a new bottomless portafilter. It appears to be cut on a lathe which creates a neat uniform cut. My only complaint is the sharp edge left by the cut. I filed the resultant edge before using to avoid the possibility of cutting a finger.

Off Centered Review by wildguy
Item Rating

The cut was both crooked and off-centered. The cut gouged into the handle side of the portafilter making the metal thin where the majority of the pressure will be applied. I had to grind the edges smooth so I didn't have sharp ledges.

I'm pretty sure it will work fine, but I'd like to see little more attention to detail.

Note: This is my second portafilter mod. The first one was much better.

Nice Option Review by Ira

Espresso aint cheap. This is a nice option to repurpose that single portafilter (who uses that thing anyway?) at a reasonable price. I put my VST 18 gram basket in my new bottomless portafilter and the blind basket in my double and we're good to go.

Cons: My repurposed Rocket portafilter doesn't sit flat when tamping unless I tamp with the handle hanging off the edge of the tamping surface...not a big deal, but maybe one designed as a bottomless portafilter would not have the same issue?

Great Job, sub-par communication Review by Jacy

I am very happy with the modification to my portafilter. The edges are smooth and it is very well done. However, I was less than satisfied with the level of service provided throughout the process. I would appreciate if an email with a tracking label and shipping instructions were sent after the order was completed (even if it cost a little more - it cost me $11 to ship). It would be clearer and more convenient.

After shipping my portafilter, I received no notification that it had been received or when I should expect to get it back. After contacting Espresso Parts, they told me it would be cut and shipped on Friday, After not receiving any notification by the following Tuesday, I contacted them again and was told it would be cut and shipped that day. It was, and I received it the Monday after that - 15 days after I shipped it to them.

To recap, I am very happy with the final result, but I would like clearer instructions, more communication, and faster turnaround.

Great Portafilter Mod Review by ray

If you have an extra portafilter lying around you wont go wrong by making it bottomless. Espresso Parts did a great job!
