  • 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

Han L asked: 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. Apr 8, 2014

David B: 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. Apr 9, 2014

Derek A: Yes, this is also a problem I faced as well. There isn't enough room in the portafilter to hold a sufficient amount of un-tamped, ground coffee for a complete 3 shot puck prior to tamping. I did find a solution however - and it works every time for me. My Rocket machine came with a grey colored, long handle, plastic scoop for measuring coffee. One measured scoop of whole beans is sufficient for one shot of espresso. Now, remember this 58mm bottomless portafilter is a 3-shot capacity accessory.

Here are the steps I use:

TIP: You will need to use about a 25% larger grind setting on the grinder compared to the grind setting you use for the normal 2-shot portafilter. That's the other key to success with this 3-shot bottomless portafilter!

1) measure three scoops whole of beans (or the correct amount for 3-shots) and put them in your grinder.
2) place the bottomless portafilter under the grinder, start grinding and fill the portafilter, but stop short of filling it to the point of overflowing.
3) take the portafilter and knock the coffee down to the bottom by banging it down 2-3 times onto a block of wood (to protect your kitchen counter and prevent damaging your portafilter!) There will now be enough room for the remainder of your 3 scoops of coffee.
4) finish grinding the remainder of the of whole beans into your portafilter.
5) Level and Smooth out the coffee grinds using your normal method to make sure you will make a consistently dense puck! (I use the handle of my coffee scoop for this!)
6) tamp down the grinds to make your puck. I do it on a digital scale until I see about 24-26 lbs of force on the display

Your puck is now ready for extracting 3-shots of espresso.

Good luck and enjoy your espresso!!

Karen S: I use the bottomless portafilter with my Rocket Gioto Evoluzione and Mazzer mini type-A grinder. Heres my formula: 19-20 grams of coffee, 30 lb tamp, ground so that this yields 2.5 oz double shot in the 25-30 second range. With my beans (Malabar Gold from Bean Central roaster in Nashville), even with a mid- grind shake of the portafilter to level, the ground coffee overflows and pyramids above the rim pre-tamp. It is well below the rim post tamp. The shots are picture- perfect. Hope this helps,
Dave

Scott T: I have never weighed my ground coffee when filling this portafilter, so I don't know about the weight. I do know that it does take seemingly quite a bit more coffee than normal. Shape of the basket is NOT tapered at the bottom like many baskets, so the tamper is going to go deeper for sure. I adjust the amount of coffee in the basket so it just levels off before tamping, and then after tamping rests below the basket edge about a millimeter - no more. Apr 9, 2014

James M: My 58mm isn't noticeably wider than my others. (I've just checked, to be sure!) But, like you, I've found that it wants a much bigger dose than my ordinary double spouts. I give it three generous shots'-worth.
One way of doing it, if you don't want to give yourself too much of a caffeine overdose, is to treat yourself to a wasteful ristretto, and cut the shot off at a double. Otherwise, yes, you're gonna need a bigger shot glass...

Derek S: You are right, it is wider than the standard portafilter. When I use the bottomless one, I just use 2 full scoops of ground coffee, like I do with the standard portafilter (using the scoop that came with my Rocket) and assume that this is enough coffee (I am sorry, I don't know what this dose weighs). As I recall, it doesn't come up to the line inside the portafilter after I tamp it down, but it is close Apr 10, 2014

Michael M: The basket that comes with this bottomless protafilter is actually meant for a triple shot of expresso - thus the amount of coffee needs to be adjusted accordingly. You can also remove the triple shot basket and replace it with singe or double shot baskets - and use the amount of coffee that you are used to using with these smaller baskets. Apr 9, 2014

Thomas Y: The basket in that bottomless portafilter is actually for a triple shot. It's not wider, but deeper. I just took the basket out and used the one from the standard double portafilter. Instant perfect dosing & tamping. Apr 9, 2014

Noah R: The portafilter comes with a triple basket, which I have been unable to master. I use a double basket and dose it the same as I would with the standard portafilter. Hope that helps. Cheers! Apr 9, 2014

Thomas Y: 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. Jun 4, 2014

James V asked: Good Morning! Please explain what is the need and/or advantage in the bottomless portafilter. Does it increase the volume of the extraction? Oct 11, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Teri KStaff: 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! Oct 11, 2013

Total necessity

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!

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.

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.

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.

Pros:
Easy To Use, Commercial Grade, Easy To Clean

Cons:
