Product Description

If you haven't seen the coloration that comes out of a bottomless portafilter, you are really missing out. This unique way to extract shots with the 58mm Bottomless Portafilter for Rocket Giotto and Rocket Cellini models offers a great view into the process as rich hues of brown come waterfalling out from underneath your brewhead unit.

How the 58mm Bottomless Portafilter Works

  • Lightly fill the portafilter basket to the top
  • Use your finger to gently even out the grounds
  • Lightly press the tamper into the grounds and find a good center point
  • Evenly apply approximately 30 lbs of pressure to the grounds
  • Tap the side of the portafilter to reveal loose grounds
  • Lightly tamp these loose grounds into place
  • Sit back and enjoy one of the coolest looking effects in espresso extraction

For this specific bottomless portafilter, the 58mm for rocket espresso seems more wide in size for the puck. I'm wondering for best amount of doze, how much should I doze? 18-20g? But when I tamp it, its literally hitting the bottom of the filter like its nothing because it doesn't seem like its a lot of coffee. Please help.

Best Answer: I haven't used mine in a long time, but I did find the same thing. I subsequently read somewhere that the bottomless portafilter is sized for a triple shot., not a double. Therefore I would think it might be more like 24-27g. I use 18g in the regular double portafilter.

Will this fit a Rancilio s24?
gene f on Jun 3, 2014
Best Answer: I have a Rancilio bottomless portafilter that I got for my old Silvia. The folks at SCG told me that it would fit the Rocket. (I ended up getting the Rocket one to match aesthetics). So if the Silvia one fits your Rancilio machine, so should the Rocket.

I'm curious as to the quality of the shot in regards to this specific portafilter. I have a V1 Silvia, and from what I see there are many 58mm portafilters that are bottomless. Other than the handle being the same, is there any difference in quality of the shot using this over say a Rocket bottomless portafilter on the Silvia V1? thanks!

Best Answer: The important thing will be in the fit. Portafilters spend to be very brand-specific, and the tabs on the sides of the portafilter can not only be a different height and length, but also orientation, and may not create as nice of a seal. We have definitely found that the Rancilio branded bottomless portafilter creates a better seal with the Silvia, so it can push water through the coffee rather than leaking around the edges of the portafilter, degrading the quality of the shot. Hope this helps!

I am not sure, is this original rocket-made portafilter or is it a one with cut spouts, as there are many of those out there?
A shopper on Nov 2, 2014
Best Answer: This Bottomless Portafilter is the Rocket branded portafilter, and is manufactured without a bottom as opposed to having been modified from a portafilter with spouts.

I have Delonghi Vintage Icona machine can I use this product with it?
And if yes do you ship to the UK?
A shopper on Oct 17, 2014
Best Answer: Unfortunately I am not sure that this Bottomless Portafilter for Rocket machines will work for your DeLonghi unit, as portafilters are brand and machine specific due to their size, tabs and tab placement. Without testing I would not know if it will work for your machine. Unfortunately we don't ship internationally. Sorry I can't be of further assistance on this for you!

Does this portafilter fit a La Pavoni EPC-8? Thanks in advance.
A shopper on Aug 31, 2014
Best Answer: No, this 58mm Portafilter is too large for the La Pavoni EPC-8 machine. We do not have a bottomless portafilter for the La Pavoni machines.

Good Morning! Please explain what is the need and/or advantage in the bottomless portafilter. Does it increase the volume of the extraction?
James V on Oct 11, 2013
Best Answer: There are a few advantages to using a bottomless portafilter for extraction. One is that you are able to view the extraction as you brew in order to be sure that your tamp is even, since with a bottomless you can see that your espresso flows from the center of the bottom. Another is that you do not lose heat as the espresso travels through one or two spouts on a regular portafilter. And the biggest advantage is that you can often use a triple sized basket with a bottomless portafilter, since the bottom is open and can accommodate a deeper basket. This 58mm Bottomless Portafilter for the Rocket Models includes a triple basket. Hope this helps!

Will this portafilter fit a Saeco Sirena? I am looking for a bottomless portafilter for a Sirena. Thanks
A shopper on Aug 24, 2012
Best Answer: Unfortunately we do not offer a bottomless portafilter that is compatible with the Saeco Sirena. Though they are both 58mm, the fit of the Bottomless Portafilter for Rocket Models does not work with the Sirena.

Is this a double or triple shot? Does this one have leak or spray issues like the other bottomless for tne silvia rancilio? This would be for my silvia. Thanks
Jake E on Feb 17, 2012
Best Answer: The 58mm bottomless portafilter for the Rocket Giotto and Rocket Cellini is a triple shot. Unfortunately, it does have leak and spray issues when used with the Silvia.

FantasticReview by JKM
I using for single shot with the single portafilter basket now. For back-flashing, I use permanently the single portafilter (comes with the Rocket) with the blind basket so no need to switch the baskets. (Posted on 11/10/2014)
Very pleased!!!!Review by James M.
I'm very happy with my purchase....everyone should get one of these portafilters! It has made the Crema thick and rich compared to my double or single spout portafilters! I find it very forgiving especially with an over pressured tamp. Good price,good quality and very nice people to deal with...I certainly will deal with Seattle coffee gear again!
If you don't own one,you're doing yourself a great disservice when pulling an espresso shot or making a cappuccino or latte!
Thank you SCG (Posted on 10/9/2014)
Total necessity Review by Z@K!
I bought this because I thought it looked cool when it pours, but it turns out to be an absolutely necessary component in making the perfect shot of espresso. It allows you to fine tune by letting you see if you are grinding your beans too course or too fine (it sprays everywhere when it's too course), or if you are packing your basket too hard. I had no idea what a necessity it was until after I bought it. If you are serious about coffee you must have one of these! (Posted on 5/26/2014)
A must haveReview by Robert
I use the bottomless daily (unless I am pulling the shot into two cups, then I use the double spouted). Great diagnostic tool for adjusting grind or when switching coffee. It also makes it easier to identify when to stop a shot.
This portafilter also allows you to experiment with other filter manufacturers that are deeper than the stock double. (Posted on 4/12/2013)
Excellent qualityReview by Kim
I got this as part of the package for purchasing a Rocket espresso machine. It is beautiful and matches the single and double portafilters included with the machine. I can believe this item is worth about $70. Commercial quality. (Posted on 9/16/2012)
Fantastic!Review by Daniel J
Started using this portafilter to improve my shot pulls. A little messy when first dialing in a grinder (espresso can shoot everywhere if the grind is too coarse), but once the grind is close to where it should be this item works well to tell you what adjustments need to made.

The feedback I received from this portafilter improved my pulls more than anything else to date.

Easy To Use, Commercial Grade, Easy To Clean
