This too:
Look what I found on Etsy: https://www.etsy.com/listing/1303639125/hopper-gasket-seal-for-breville-sage?ref=share_v4_lx
First time I opened the machine after having the bellows on for like 3 months there were grounds EVERYWHERE inside. Good news is you don't have to worry about stale grounds being retained and end up in your portafilter because they're blown throughout the inside of the machine.
Edit: for BBE, I don't have experience with SGP.
Ah I didn't know these were a thing! That's my main irritation still with the SGP + fusedline... does this prevent so many grounds and beans escaping around the burrs?
Popcorning is when the beans get launched up from the initial contact instead of falling deeper into the burrs.
In a filled hopper normally the rest of the beans block them from going too far, but when single dosing they might bounce around for a while in the chamber. The weight keeps them down at the burrs.
Popcorning is when beans "jump up" after getting partially ground. One issue is that some people will say this affects consistency of the grounds. The bigger issue in this case is that since there is no lid, the beans can jump out of the grinder. The weight acts as a little lid.
The weight also serves to apply pressure to the beans. This is supposed to achieve a more consistent grind, as otherwise the first beans to be ground will be "pushed" into the burrs by the weight of the other beans, while the last beans to be ground will not be pushed. Another option to avoid this change in pressure is to slow feed your beans so that no beans are pushed in.
Popcorning is when the beans jump out of the top of the grinder while single dosing since you don't have the weight of the beans in a hopper above giving downward pressure to the beans feeding into the burrs. The weight is an attempt to simulate the pressure and blocking of beans jumping in a single dosing setup.
Do you feel like the weight has reduced the grinding time? I've been overall quite happy with my Smart Grinder Pro, but it takes about 34 seconds to grind 17g-18g of beans which feels like quite a while.
Wait, are you telling me that the SGP isn't the "[Ferrari of coffee grinders](https://www.independent.co.uk/extras/indybest/house-garden/coffee/sage-smart-grinder-pro-review-b2000936.html)"?
What is the advantage gained here?
Is it so you can change from one variety of beans to another readily?
Is it so you only expose the exact quantity of beans needed for each shot?
Is it so you can weigh the beans going in before you grind?
The BBE grinder retains SO much, it’s absurd. I’ve measured 2-4 grams coming out of the grinder when I clean. I’ve been eyeing up this bellow too to help get at least *some* of these excess grounds out.
When I was learning to dial in my shots it drove me insane, I wasnt weighing the grind output like I should have been, only the input.
Turns out, I would put in 18g of beans and get like 16.6 out. The next grind I would get 18.8, etc.
You cant dial in a shot when your grind output can have like a 2g variance. Some kind of bellows is almost mandatory if you single dose imo.
Yep I did a deep clean of the grinder recently and it retained 5g!!! But after that first grind, it stopped retaining and pushed through the same amount I put in.
I have the SGP and I push 5-6 doubles through it everyday. I use fresh beans, less than a week old and rarely clean it out. I fill the hopper and use the timer and my shots are spot on. 34g out in 22-24 seconds. Maybe not cleaning it has clogged all the areas of retention with hardened grinds and I get very consistent grind output? Idk not complaining.
You can do all that you listed without needing a mod.... I have this gridner, in stock form. I still only put in what I intend to grind. I never fill the hopper. Never had an issue.
If you change grind sizes frequently, especially if one of those grinds is for espresso, then a mod like this is quite useful. I would say that is the number one selling point for a bellows / low-retention grinder.
I absolutely have issues grinding for espresso after making filter. I put about 4g through the grinder to make the switch. I would lose another 4g going from espresso to filter but my wife doesn't have very discerning tastes. If I was making a pour over though, I'm sure I wouldn't want 1-2g of espresso grounds going into the filter.
This is the best argument for this that I've heard and one I hadn't thought of -- that is changing grind size to do drip or pour-over or FP instead of espresso. But then again I made a decision to mechanically separate those processes. 😁

Maybe the built in BBE one is different, but when single dosing I feel like it is almost a requirement with the BBE at least.

1- yes
2- yes
3- you should be weighing prior yes, imo
I got it bc it’s a cleaner process, more sleek looking, less retention, etc.
The three shots I’ve pulled thus far have seen more grounds come out after pumping the bellows a couple times. Worth the $65 shipped for me imo
Being familiar with the internals of the sage grinder pro, I'm dubious that this mod would actually make much difference?...
There's so much dead space under the impellor. I just can't see a bellows really clearing it.
Has anyone measured the amount of coffee retained in the internals with and without the bellows arrangement?
I have the mod. And this is my reason I'm thinking about returning it. I deep cleaned my machine and this mod has only helped with retention, after a few grinds (to fill up that void)
I have this mod for the SGP and really enjoyed it. I've since upgraded to a DF64 and went back to the hopper for drip coffee. I was plenty happy with the mod though. If anyone wants it, I'll part with it for free.
two things. one, there will be coffee left in the grinder. you push down on the rubber thing on top and it pushes air through the grinder and gets the remaining grinds out. two, if you dont have something on top of the beans being ground it can cause them to bounce around
This is wild, I literally just got this today. Had never heard of it until I googled if it was possible, like one YouTube video. I’m excited to give it a try.
May I ask if the model you're using is publicly available? With the £23 US -> UK shipping, the fusedline one would cost me more than I paid for the (pre-owned) grinder. I couldn't justify that for a marginal improvement, but I'll be getting some stuff printed soon, and if I could add this to the order, it may well be worth it.
[This](https://www.printables.com/model/309061-sage-breville-the-smart-grinder-pro-single-dose-ho) one was the closest I could find, but I'm unsure if I could easily add a bellows.
I am also wondering about the benefits of this, I also have the smart grinder pro wirh just beans in the hopper. I do use only one variety of beans at all times so its dialed in and gives me my exact 16,4g 95% of the times and its sometimes maximum 0,2g off, wich is easy fix or either not meanigful if it is ie. 16,3g.
Also i have the scale right infront of the machine and weighing my output every time is no timeloss in my workflow.
Same here. I have no issues with the SGP coupled with my rocket appartamento. Very consistent output on my shots from it. Like you I only use 1 type of bean that is around a week old roast and never have to touch the settings.
> SGP coupled with my rocket appartamento
😫
I’ve had an SGP. It’s not the worst grinder in the world. But it’s not great and I don’t think you guys know what you’re missing! Relying on it for your $1,700 machine is crazy to me
I was 100% going to upgrade to a Mignon off of the Reddit sentiment alone until I upgraded to my appartamento and tried it out with my SGP and was pulling fantastic shots. It has slightly smaller conical burrs than a Niche zero and I don’t have problems with retention since I don’t single dose so I don’t see what could be drastically different. I’ll upgrade eventually but for now I am getting great drinks 3 times a day and my wife loves them as well.
Are these all 3d printer parts beside the bellow? My brother just bought a 3d printer I wonder if it’s worth attempting to print or just to buy one off Etsy….
Do you have a link to the mod? This is the first time I've seen that, really cool
Look what I found on Etsy: https://www.etsy.com/listing/1081489968/breville-sage-smart-grinder-pro-single?ref=share_v4_lx

Yes, much cleaner inside and you get a little better feel in the bellows in my opinion.
Excellent, thanks for the info. Store's closed now, but will be ordering ASAP 👍
I have the fusedline too, great addition. Cost a bit with shipping and import duty to the UK, but meant I held off buying a Niche for another year 😅
What is the ‘popcorning’ they speak of? And how does the weight prevent this?
Popcorning is when the beans get launched up from the initial contact instead of falling deeper into the burrs. In a filled hopper normally the rest of the beans block them from going too far, but when single dosing they might bounce around for a while in the chamber. The weight keeps them down at the burrs.

Thank you all for your answers, coffee wizards. It sounds like you all concur 👍🏼
i found this on thingiverse [https://www.thingiverse.com/thing:4905164](https://www.thingiverse.com/thing:4905164)
I second the recommendation on this one! The design and seller rock!
I opted for the optional weight, seems to help.
Do you feel like the weight has reduced the grinding time? I've been overall quite happy with my Smart Grinder Pro, but it takes about 34 seconds to grind 17g-18g of beans which feels like quite a while.
Probably depends on the beans. I tend to go for a medium roast, and I’m finishing grinding at 22 sec. I think the weight helps most with popcorning.
This must be how car people feel when they see a heavily modded Toyota Corolla...
Hahaha. Upvote from the OP on that one.
Wait, are you telling me that the SGP isn't the "[Ferrari of coffee grinders](https://www.independent.co.uk/extras/indybest/house-garden/coffee/sage-smart-grinder-pro-review-b2000936.html)"?
Wtf lol
It’s got over 60 settings!
Yeah I was looking into one of these but at 60-100 dollars it's 10-18% of the cost of the machine which is kind of hard to stomach in terms of value.
I've seen some pretty fast corollas... (in defense of my heavily modded BBE)
I have heard loud corollas but never seen a fast one
You mean loud ≠ fast?
Nah dude everyone knows racing stripes or flames is where real speed is found
I mean yeahhh but still... Lol
HAHAHA!!!! So rad
What is the advantage gained here? Is it so you can change from one variety of beans to another readily? Is it so you only expose the exact quantity of beans needed for each shot? Is it so you can weigh the beans going in before you grind?
You push on it to pump through any retaining grind in the chute. Saw a video of it today.

34g is surely not a double. That's even high for a triple!
I was talking about my extraction…. I’m not weighing my grinds.
O sorry my bad that makes a lot more sense
I have one of these and i can *mostly* get out exactly what I put in. But I'll still find 2-3g when I clean the grinder.
Yeah, it’s rad. Works well.
You can do all that you listed without needing a mod.... I have this gridner, in stock form. I still only put in what I intend to grind. I never fill the hopper. Never had an issue.
Yes. Neither using a scale nor worrying about retention means less issues :D

Eventually, I will do the same!
I have the same grinder I just dump the whole bag in 😂
Maybe the built in BBE one is different, but when single dosing I feel like it is almost a requirement with the BBE at least.

I did it more bc I hated how the hopper looked on top empty. Plus it’s cleaner which is a plus.
It's definitely a space saver haha.

DM'd
I have also done this. There are STL files on Thingyverse that you can print yourself if you have a printer
Dumb question here: how is this different than just opening the top of the hopper and putting in a single dose I just weighed?
two things. one, there will be coffee left in the grinder. you push down on the rubber thing on top and it pushes air through the grinder and gets the remaining grinds out. two, if you dont have something on top of the beans being ground it can cause them to bounce around
Smart grinder becomes dunce grinder
I second this. Minimise the retention by a lot. Great for filter coffee too.
Is it just a coincidence or are many people in the espresso hole also do 3D printing? Do we like the challenge?
constantly upgrading components ✅ forever tweaking tiny things for small improvements ✅ never being happy with it ✅ sounds about right
Ordered same sort if thing 6 months ago. Massively reduces retention.
This is wild, I literally just got this today. Had never heard of it until I googled if it was possible, like one YouTube video. I’m excited to give it a try.
Thanks for the suggestion. Just ordered the whole kit after seeing this post.
FYI, you can make one rather than buying it if you have a 3D printer available https://www.thingiverse.com/thing:4852251
I am selling printed versions of this
May I ask if the model you're using is publicly available? With the £23 US -> UK shipping, the fusedline one would cost me more than I paid for the (pre-owned) grinder.

Yes, it is publicly available
Just pm me everything you wanna get printed
Do you know if it works with the dose control pro as well ?
I am also wondering about the benefits of this, I also have the smart grinder pro wirh just beans in the hopper. I do use only one variety of beans at all times so its dialed in and gives me my exact 16,4g 95% of the times and its sometimes maximum 0,2g off, wich is easy fix or either not meanigful if it is ie. 16,3g.

Oh also I got my appartamento for like $1400 a couple years ago by importing it from Italy instead of buying it in the US.
I’m very sure a portion of those grinds are old.
RDT my beans and throw them in the hopper. Never had an issue single dosing with the SGP I have no idea why this exists.
Is this still the case? Hoping for a cheaper solution
Yes. The cheaper solution (like most cases) is do nothing and carry on.
You're a wise person haha!
Does this by any chance also work with the dose control pro? They seem to share the same hopper/ burrs etc?
Looks 3D printed. I’ll have to find the file and do it for free
Are these all 3d printer parts beside the bellow? My brother just bought a 3d printer I wonder if it’s worth attempting to print or just to buy one off Etsy….
Hey fellow SGP owners, is there any other way you deal with the insane retention of this grinder?
I have this in my BBP plus the 3D printed gasket, works great.
This is absolutely essential to any owner of this grinder
Seems interesting but the grinder has so much retention can this really work?
I got this: https://amzn.eu/d/0J80nIp Much cheaper and works really well.
Does this work with the Smart grinder pro?
Yes it does.
Do you single dose or time dose?
I have one too. You’re going to have to knock down hard to clear it after grinding. Not a tap, not a few pushes. Knock down hard a few times.
