Single Dose Hopper with Silicone Bellows and Anti-Popcorning Weight | Compatible with Sage Smart Grinder Pro | Black

The Sage Smart Grinder Pro is a good machine but fitting this single dose hopper/bellows unit makes it into a much more useful one! I don't have mess about changing the beans in the hopper if I want to use a different coffee bean etc. I was impressed with the quality of the fit and the bellows arrangement works very well. Overall a great product and thoroughly recommended.

Firstly, if you are buying this product it is very likely that you are not a coffee newbie, you will have mastered the basics, and are now nudging into coffee nerdland, so I'll assume those reading this know how to load a portafilter correctly. The kit looks to be mainly 3D printed, except for the silicone bellows, but the finish is good apart from a little roughness on the stopper weight. Although plastic, the parts are pretty robust, and they fitted well in my Smart Grinder Pro. I was fitting mine to brand new grinder, so if you are modding a used grinder, I suspect a thorough clean and vac out would be a good idea before fitting. The parts generally locate easily, but there are no instructions included. The orange insert has two protruding "pins" and one of these must align with the small pit in the grinder body that contains the safety cut off switch. When you insert the black upper collar and rotate it, you have to feel carefully for the moment when the lug engages the pin on the orange insert and pushes it in to activate the safety switch. When you feel a slight "click" as the insert pin carrier locates in the groove on the collar, stop rotating immediately. If your grinder does not function after fitting, it will be because the pin is not depressing the safety switch, remove the black collar, check the pin alignment on the orange insert, and try again. Now, what you really want to know is... does the kit do what it says on the tin? I did a weighing test, and with the kit fitted, an 18g bean load (dark roast, setting 6), produced 15.12g of powder, this is probably more than the stock machine, as the insert fills and closes off some voids in the grinder. The real magic comes when you pump the bellows at the end of the grind, that 18g load produced 17.89g of powder. So, I would say that that is defintely not too shabby, and that the kit does what it is intended to. Note that I pumped the bellows with the weight in place, this has grooves in its sides which focus the air during pumping. I have not tried pumping without the weight in place, but I suspect the air flow would not be as strong, and probably not as effective at dislodging trapped powder. The kit is expensive for what are essentially a few bits of 3D printed plastic, but it will transform your existing Smart Grinder Pro into an effective single dose grinder. Even buying with a new grinder as I did, the numbers add up, the combined price is much less than half that of a Niche Zero. Now, I'm not saying that this combo is as good as something like a Zero, especially where light roasts are concerned, but it is certainly an economical way to see if the faff-on of single dosing works for you before laying out the big bucks. Happy camper here.

I have been enjoying this little attachment for my coffee grinder as I wanted to reduce the amount of retained coffee in the grinder between drinks. This has solved that problem in a fairly sleek way. The printed parts feel decent quality and fairly sturdy. The silicon bellows work well, hopefully they hold up to near daily use. Its easy to install and easy to clean. Just twist it out and give it a brush down. It's handy being able to dose by weight and reduce the amount of coffee oxidising in a big hopper. The noise level is more or less the same with the this attachment.

Excellent addition to the grinder, effectively turns it into a single dose grinder and does a good job in eliminating the retention which is normally a bit of a problem with the sage smart grinder pro

I got this version as I prefer the lower profile compared to other single dosing options for the Sage Smart Grinder Pro that are cheaper. It was easy to install. I weigh my beans in and ground coffee out and there is virtually always no retention. I use the bellows part at the top to weigh out beans rather than using a separate dosing cup as there is no need when this can do both. The bellows also work well to get all the grounds out to reduce retention. I was really reluctant to buy this but I don’t regret it. It’s much easier to ensure I have the right quantity of beans and that I have minimal old grinds being left for the next shot (though I always purge first before making a shot the next day). It does seem expensive though but so far there isn’t an alternative that has this smart streamlined look.

It looks great on the grinder and works very well. I have done a deep clean with using air compressor to fully remove all the coffee from it and the first grind was about 2,5-3g less for some reason but the grinder inside stayed nice and clean. It is so much cleaner than how it was before. I really like it.

Would have been 5 stars but not value for money

Wasn't sure about this, £50 for ostensibly a 3D printed item, I felt I was taking a risk. Not the case, this addon for the Sage grinder does exactly what it says. Fitting was a piece of cake and has turned the grinder into a very flexible single dose unit. We are now able to switch beans between each cup with ease and the air pump means that there is very little mixing of roasts. on the whole highly recommend this to add flexibility to the Sage Grinder.

Just great. No more retention.

Cumple bastante bien su función, como es el único en su tipo que encontré pues no lo puedo comparar, a pesar de ser mayormente impreso en 3D queda a la perfección, eso me gustó.

Ho utilizzato il Sage Smart Grinder per un pò di tempo con il suo dosaggio temporizzato, e nonostante la bilancia, i colpi risultavano incoerenti. Arrivato a casa questa tramoggia monodose tutto è cambiato, colpi coerenti e gusto piacevole usando lo stesso caffè di prima. Svolta per me e consigliatissimo per voi

Ich gebe es zu: Das hatte ich nicht erwartet. Ich hatte meine Sage SGP seit Monaten schon im Single Dose Betrieb, aber halt ohne Blasebalg. Beim reinigen kamen so immer um die 3 gr heraus - der sogenannte Totraum. Damit war ich eigentlich immer recht zufrieden. Bis ich mich schließlich doch durchgerungen hatte und 50 € für etwas Plastik auszugeben. Natürlich hatte ich gehofft, dass es besser wird. Erwartet, oder besser gehofft, hatte ich auf 1 - 2 gr Totraum. Stattdessen wurde ich total überrascht, denn es funktioniert super!!! Mit diesem neuen Tool liege ich irgendwo um die 0,3 gr, das ist überragend. Und sonst? Alle Teile sind sehr gut verarbeitet und passgenau. Das "Anti-Popcorning"-Gewicht benutze ich bisher nicht, es funktioniert auch so tadellos. Über den Preis möchte ich in Anbetracht des tollen Ergebnisses nicht reden. Klar sind 50 € für ein bisschen Plastik viel Geld, aber es funktioniert. Und außerdem bin ich nun gedanklich erstmal wieder ein Stück weit entfernt, mir für 600 oder 800 € eine Single Dose Mühle zuzulegen. Über die Haltbarkeit kann ich natürlich noch nichts sagen, aber bis dahin lautet das Fazit: Glasklare 5 Sterne.

I installed the single shot hopper and belllows today, it was super easy to install, and it is also relatively easy to uninstall. I asked about removing the single dose hopper prior to my purchase, thinking I would swap back and forth between this and my large hopper when grinding beans for moms drip coffee, which I usually do in one session for her big ground coffee can. Needless to say I am very happy with this single dose hopper it works nearly perfectly, I have ordered a gasket to set beneath the hopper that should make it truly 0 retention. My espresso bar has been updated, I have added a single dose hopper with bellows to the grinder. This setup has zero retention of ground beans, which allows for consistent dosing of the shot. I’ve added a tamping station to house my bottomless portafilter, puck screens WDT tool, distributor and tamp. This morning i pulled the best shot ever, using the bottomless portafilter. The BP unit has really made a difference allowing me to analyze my shot pulling skills. Behind the knock box is a holder for measured shots, which I prepare 10 doses at a time. In the last photo you can see the pucks after pulling shots. The portafilter and screen come out absolutely clean. I may have to go back into the espresso business.
