Product Description

Designed specifically for Rocket Espresso, the Mazzer Mini Electronic Grinder proudly boasts the Rocket logo and is the perfect companion for your Rocket Espresso Machine. Ideal for home use or any light commercial environment, the Mini Electronic Grinder has a stepless grind adjustment and programmable electronic dosing to make filling your portafilter a snap. Choose from a polished stainless or black version.

Features & Functionality of the Rocket Mazzer Mini Grinder - Type A

  • Large Capacity: The sturdy clear plastic bean hopper with finger guard holds a whopping 1.3 pounds of beans and features an integrated trap door that allows for easy changing of beans without emptying.
  • Consistent Grind: The stable stainless steel 64mm burr grinders are flat (rather than conical) and remove for easy cleaning. Designed to operate at a low RPM (rotations per minute) so that minimal heat builds up and is transferred to your beans.
  • Doserless: The adjustable doser gives you control of churning out between 4 and 16 grams per pull, and the Type A features a digital display with shot counter.
  • Stepless Control - Revel in having precise control over the consistency of your grind.
  • Large Hopper - Super large hopper holds 1.3 pounds of beans.
  • No Reference Marks - Because there is no end to the turns on the stepless knob, there are no markers to help you recall your grind settings from each use.
  • Too Much Machine? - This is a high quality, high quantity commercial style grinder. Make sure the features fit your home needs.

Will the Mazzer Mini grind coarse enough for French press?
A shopper on Dec 29, 2013
Best Answer: I, too, am considering getting this for the occasional drip/press, but will mainly use it for espresso... From the countless hours/days of research I've done on this, the most important thing here is to mark the stepless dial once you've dialed in a good espresso before switching to a coarser setting for drip/press, so as to not lose your "perfect setting".... I just hope I don't have to split an Atom to get the right setting, otherwise this will be a nuisance.

There is a great thread on home-barista to answer what you ask... search for "Good approximate Mazzer grind setting for espresso/French press". I hope that helps.

How do you reset the counter on the Mazzer Mini type A?
A shopper on Mar 19, 2013
Best Answer: I don't think you can reset the counter. I was wondering the same thing and did a bunch of research. The answer that I finally accepted was why would you want to reset the counter anyway.

Stuart O on May 5, 2015
Best Answer: You can certainly interchange the hopper, but the beans will still be down in the burrs.

What is the best cleaner to use on the polished steel of the casing if the mini mazzer to make it gleam yet is safe enough not to harm it? Will ordinary window cleaner do the best job?
A shopper on Jan 10, 2014
Best Answer: Yes, that is what we recommend! We tend to use Windex on the polished finish of this Mazzer and all of our stainless steel machines.

Ok so I'm slightly confused. In one of your video reviews you guys say this Rocket branded mazzer mini is covered in polished aluminum, but in the description here it says stainless steel. So does this match the Rocket machines perfectly?
A shopper on Oct 2, 2013
Best Answer: This Rocket Logo Mazzer Mini has a shiny stainless steel finish which matches the sheen on all of the Rocket machines with the exception of the Rocket Cellini Classic, which has a brushed stainless finish. I think the video and online verbiage use "stainless steel" and "polished aluminum" interchangeably. Hope this helps clarify!

do you have this grinder with smaller hoper that fits under a regular kitchen cabinet space?
A shopper on Feb 24, 2012
Best Answer: There is a replacement hopper you can purchase for the Mazzer Mini that comes in at right around 6", making it about 1.5" shorter than the original (which is ~7.5") :

Please keep in mind that this bean hopper would need to be purchased in addition to the grinder and that the short hopper is currently out of stock (expected to be back in stock in April).

For the home-the best grinderReview by Alex
No matter what high end espresso machine you buy, you must have a great grinder. It's like having a pair of shoes they must match. This is the best match for any high end machine. (Posted on 9/25/2015)
My first grinderReview by Sam
I did a lot of research and decided on the Mazzer Mini Type A. Since we only pull a small amount of shots at a time, the doserless model makes much more sense. And since you can set the number of seconds for the grind, it accurately doses the right amount each time so it's perfect.

The built quality is truly exceptional. This might be the mini model but it's a beautifully built machine that is rock solid. The PRECISION sound of the grinding is also quite satisfying. I have the larger hopper and it fits perfectly under my 19" cabinets. I don't use the setscrew to lock the hopper in place. I don't feel it's necessary, and I can close the gate and lift off the hopper to refill without having to move the entire thing from under the cabinet. Your mileage may vary here depending on how much clearance you have.

It's easy to dial-in and adjust. I used a digital gram scale to set it to 18g doses.

My espresso machine is a Rocket R58 and this grinder pairs beautifully with it. My previous espresso setup was a Breville Barista which was great, but we've not moved into the semi-pro league with the Rocket R58 and the Mazzer Mini.

This machine is costly but worth every penny, plus Sattle Coffee gave me a 10% coupon code so I saved some money.

I would definitely recommend this grinder and am quite happy with my purchase.

Fantastic High Quality GrinderReview by Beepmeister
After months of investigating different grinders after my ancient Capresso died (and I wanted to upgrade to a better grinder) I bought this Rocket Mazer Mini Type A. It has been a revelation: much better tasting coffee (yes most definitely can tell the difference). I looked at the Rancilio Rocky, Baratza Vario W, Anfim, Compak, etc. Gail's videos (comparing different machines) were very helpful; check them out on YouTube. Mazer Pros: high quality, solid (looks like it will last for years), easy set up, easy to use, accurate dosing, easy to clean and reasonably quiet. Cons: cost (relative) and slightly messy. Bottom line: absolutely worth the money--advice on-line was right, don't skimp on the grinder! (Posted on 9/5/2013)
Very satisfy Review by Karim
Perfect for my Rocket 58. It took me around 1 pound of grinding to find the perfect adjustement. It's funny because now I have better shots even compare to the restaurant that sell me the beans!!

Very great grinder (I went in a restaurant that was having the same). Personaly I chosen the B model to keep the old look vs the A that have a digital screen.

I found that the machine don't stay clean very long as the grinded coffee has the tendency to stick a bit everywhere in the front of the machine.

Very nice look and very good machine, will recommend big time. (Posted on 2/23/2013)
64mm burrs in a tankReview by Grant
An amazing case, 64mm burrs, and mazzer's reputation is in top form with this grinder. Dr who is coming on now, so if you're reading this, just buy this grinder. it's for some reason cheaper in "rocket" branding, so thats every reason to get it. (Posted on 2/20/2013)
Build Quality is EverythingReview by Grant
I was having some issues with another espresso grinder, mostly due to wear on internal plastic parts. This grinder has surely resolved that issue. It is built and has warnings for commercial use. My home use wont be any problem for this tiny beast to handle.

Once the dosing is adjusted, this thing really helps with my routine. Very well thought out design, and I love the 64mm burrs, they produce a great, complex cup. (Posted on 1/8/2013)
Rocket Mazzer Mini Electronic - Type AReview by Michael
I purchased the Rocket Mazzer Mini Electronic Type A after weeks of waiting for SCG to get the item back in stock. The grinder arrived in near-perfect condition, with a minor slice in the electrical cord near where it exits the base of the machine. It doesn’t seem to be an issue yet. I’ll update if it becomes an issue.

I was a bit curious when I received the grinder, as the box is sealed with Mazzer tape on the top and bottom of the box, but the tape on the top had been sliced open. The flaps were stapled shut with heavy brass staples and then taped over with clear packaging tape. Aside from this curiosity, the box contents appeared to be complete. I’m not sure if this is normal or not.

To my surprise, the grinder has an electronic dose counter that counts up by “1” when the single dose is pressed and by “2 when the double button is pressed. There is no way to reset the counter to zero. I have even asked SCG staff on this. I find this unfortunate, because it would be nice to reset the counter when I clean the machine or replace the burrs, or just because I want to at this price level. After set-up and calibrating the grind times by weight, I hit 18 doses on the counter. Pressing the manual button does not increase the counter.

The machine is well-built, and robust, with only one complaint. There is an access panel behind the dispensing funnel that feels to be made out of a lower-grade stainless, or some sort of plastic. I can’t really tell, but it’s just a minor point. It is heavy, stable, and looks lovely on the counter.

I purchased the shorter hopper with the grinder and when I take the lid off, I can slide the grinder under the cabinets in my kitchen. The gate valve seems kind of junky, and if difficult to close when loaded with beans. The shorter hopper came with a gate valve of its own, but no lid. The lid for the standard hopper fits.

If you are the type of person that weighs beans before you grind, you will have to change your ways with the Mazzer Type A. This grinder does not have an auger, as some other more advanced Mazzers do, so feeding the machine a dosed amount of beans will result in the “popcorn effect,” beans bouncing up and down out of the burrs and not getting ground. You will need to fill the hopper 25-50% to avoid this.

Note that the grinder has a set screw installed to limit the range of the grind adjustment. If you intend to grind for espresso and drip, you will need to remove this screw. SCG doesn’t recommend this, and I have yet to try it. With the set screw installed, I can get a pretty close grind for Hario pour-over at the coarsest setting and also please my espresso machine.

Overall the Mazzer Mini Electronic Type A is a great machine. It’s unfortunate that the price on SCG dropped significantly (11%) only a couple of weeks after I purchased it, but that’s the name of the game. I removed one star from the "Price" for this reason. (Posted on 12/30/2012)
Rocket Mazzer Mini P Electronic DoserlesReview by Happy Coffee Guy
I've been using this grinder for about two months (Nov '11). Let me address the "quiet" check mark in the pro column. I've owned one other burr grinder and use a different make/model at work. "Quiet" in this instance is a relative term. This grinder is significantly less noisy than the other two models I have experience with.

Prior to purchase, I was concerned that it might take a lot of effort to switch between drip and espresso grind. It's actually pretty straight forward. The lever on the adjustment wheel makes all the difference as making the adjustment changes without it would be quite difficult.

I was tempted to check the "messy" box in the cons area. I think it's just the nature of ground coffee to try and escape. Fortunately, there is a "catcher" tray that collects the majority of the wayward grounds and it is easily removed for cleaning.

Despite having the smaller hopper, this unit is still an inch or so taller than the space between my counter top and the cabinets above. In the end, I found a very nice three drawer kitchen unit at Ikea that holds everything coffee. Speaking of the hopper, I really like the ability to close off the hopper feeding beans to the grinder. My sweetie prefers decaf and being able to easily switch between regular and decaf is a real benefit.

Quiet, Easy To Use, Commercial Grade, Easily Adjusted, Easy To Clean
