## Overview

The FusedLine Single Dose Hopper is a precision-engineered accessory designed exclusively for the Breville Sage Smart Grinder Pro. Featuring a robust silicone bellows capable of tens of thousands of pumps, an airtight locking system, and an innovative anti-popcorning weight, it ensures consistent dosing, reduces grind retention, and enhances coffee freshness. Ideal for coffee aficionados seeking a streamlined, mess-free single dosing experience with professional-grade results.

## Description

To install the Single Dose Hopper onto your machine: 1. Remove the original hopper from your machine and clean all old beans and grounds from the grinder. A vacuum cleaner works best. It is essential that the grinder inlet is free from all beans and grounds to ensure a secure fit. 2. Insert the orange locking ring by aligning the tabs with the slots in your grinder inlet. Ensure that the hopper is not connected to the orange locking ring at this time. Push the locking ring down firmly to ensure it is fully inserted. 3. Insert the hopper into the orange locking ring by aligning the tabs with the slots in the locking ring. Press down to ensure the hopper is fully inserted. Next, twist the hopper clockwise until you feel a click and the hopper will not twist any further. Note that this may require some force as the locking mechanism and O-ring seal. Applying an upward force (pull the hopper up) while twisting should make it easier. It is important to ensure the hopper is correctly installed to engage the safety pin that allows the grinder to operate. To use the Single Dose Hopper: 1. Measure out your dose and dump the beans into the hopper. Tip: the silicone bellows works great to measure and transfer your beans! 2. Place the anti-popcorning weight on top of the beans. 3. Set the silicone bellows on top of the hopper. 4. Press the grinder trigger to begin grinding. 5. Once all the beans are ground, pump the bellows to purge the grinder. Note that this works best while the grinder is spinning; restart the grinder if it has stopped. 6. Enjoy your freshest cup yet!

Review: Easy to install and works perfectly. - 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.
Review: Impressively Effective! - 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.

## Features

- Compatible with the Breville Smart Grinder Pro ONLY
- Includes a highly durable silicone bellows to fully purge your grinder of nearly all retention, at an affordable price. The silicone bellows can take tens of thousands of pumps without breaking or cracking, guaranteed.
- Seamlessly integrates with your Breville Smart Grinder Pro using an engineered locking ring to secure the hopper in place. A rubber O-ring ensures an air-tight seal for optimized purging of your grinder. The hopper is sized to easily accept 22+ gram doses.
- Includes an "anti-popcorning" weight that simulates a full hopper forcing the beans into the grinder burrs. This prevents "popcorning" and significantly enhances grind consistency and quality down to the last bean. The weight features integrated air channels to accelerate your workflow. There is no need to remove the weight once all beans are ground – simply leave it in the hopper, pump the bellows to purge the grinder, and enjoy your freshest cup yet.

## Questions & Answers

**Q: Can someone who bought this test input and output please. Ie measure the output. I had disappointing results from a different brand**
A: Output varies. Sometimes it’s 0.1g less other times it’s 0.2g more.

**Q: Can it be easily removed for times when I want to use the origianl hopper, for large grinds for my moms drip coffee?**
A: Yes it can be easily removed. All you need to do is twist the hopper counterclockwise, remove it and the orange lock ring, and then install the stock hopper. 

The single dose hopper can hold 40+ grams of beans so you can also just leave it on and fill it all the way up a few times. You can also just feed in more beans as it is grinding.

**Q: Can it be used without the weight**
A: Yes you can but you may get some popcorning on the last few beans. The weight helps to reduce popcorning. But the weight may not move down smoothly if you have a lot of beans in it. It has worked well for me.

**Q: What are the dimensions of the actual product?**
A: The product is 85.5mm tall with the bellows (51mm without the bellows) and is 90mm in diameter at the widest point.

### ⭐⭐⭐⭐⭐ Good but expensive
*by C***M on 29 September 2024*

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.
