More Info

Precision grinding meets portability.

This compact rechargeable grinder is engineered for baristas who want consistent grind quality without the bulk of a countertop machine. The CNC aluminium alloy body houses a powerful motor and 420 stainless steel burrs, delivering fast, even grinding for espresso through to cold brew.

Eighty micro-adjustments let you fine-tune your grind size with millimetre precision — whether you’re chasing that perfect 18 g → 36 g espresso ratio or optimising for slow, balanced pour-overs.

The magnetic catch cup locks perfectly into place, keeping things neat and efficient, while the USB-C rechargeable 1800 mAh battery gives you the freedom to grind anywhere — at home, at work, or on the road.

Built to last and designed to impress, it’s a small grinder that makes a big difference.
FAQs

Can I use this for espresso?
Yes - it's built for it. The 420 stainless steel burrs and 80 micro-adjustments let you dial in a precise espresso grind (right down to chasing that 18g → 36g ratio) and open right up for pour over and cold brew.

How is this different from your other USB-C rechargeable grinder?
This is the precision step up. Where the standard rechargeable suits occasional, single-cup use, the Mini brings stainless steel burrs, 80 micro-adjustments, a bigger 1800mAh battery and a CNC aluminium alloy body - built for consistent daily espresso rather than just backup grinding.

What's the bean capacity?
20-22g per fill - a double espresso shot at a time, ground fresh.

How is it powered and how long does a charge last?
A USB-C rechargeable 1800mAh battery, good for around 15 grinds per full charge - so you can go plenty of sessions between top-ups, at home, at work or on the road.

What are the burrs made of?
420 stainless steel - fast, even and hard-wearing.

How precise is the grind adjustment?
Eighty micro-adjustments, so you can fine-tune grind size with real precision across espresso through to filter.

Does the catch cup stay put?
Yes - the magnetic catch cup locks neatly into place to keep things tidy while you grind.

How do I clean it?
Brush out the burrs and catch cup regularly; the magnetic cup makes it quick to pop off and empty.

Should have done this year's ago

I have been using a Breville DB for years, on my second one. Have always been able to get good coffees but had to constantly fiddle with grind and dose to stop channelling. Recently nothing I tried seemed to work. As soon as I replaced the stock diffuser and screen with this, every shot is perfect. Had to reduce the dose slightly, but every shot is way more balanced without anywhere near the amount of adjustment I used to have to do.
Highly recommended this and I really should have done this year's ago. For the price it is an absolute bargain.

Next level

The Bottomless Portafilter takes making coffee to the next level. Love the look and the performance. I feel like my coffee is tasting so much better.

Perfect Upgrade

Noticed the extraction on my Breville Dual Boiler wasn't pouring equally from the twin portafilter and discovered the plastic diffusion plate had a large crack so ordered a new plate, screen and seal. Received it the day after ordering so will definitely use the Coffee Nerd team again. Well done guys!

Bottomless portafilter

Instantly improved shots! Then decided to upgrade shower screen and get a magnetic dose collar and needles to prevent channeling and I wish I did it years ago. If you’re going to spend decent cash on a machine these are a small further cost for big reward.

Coffee Nerd, is it worth your money?

I make the answer simple, yes it is. I bought the bottomless portafilter with the aluminium rosewood handle and the high diffusion espresso shower screen, both for the Breville Express machine. I am still trialling the product to perfect my coffee but having these items definately made my coffee machine produce a lot better coffee with plenty of crema on my black coffee. The service and information I got from the company is also top of the range. I strongly recommend these products. So if you are not sure, go for it, you wont be disappointed.
