Mazzer Mini Electronic B – My Endgame Grinder

This probably may spark a few questions, but I’ll try to explain to those who wonder why I went with the Mazzer Mini. Some may disagree, but this is from my perspective based on my needs, requirements and opinion absolutely an endgame grinder. It won’t be a surprise to those, who understand what this grinder or Mazzer in general represents. My goal was to end up with a small basic commercial grinder rather than a top-end domestic model. 

And this just happened, I chose the Mazzer Mini. I want an on-demand grinder, not a single doser, that is build by a manufacturer with solid reputation for quality and longevity of their grinders, a grinder that will last for the rest of my life. And Mazzer Mini Electronic B is that grinder. 

Right out of the box, the grinder felt rock solid on the first touch – the quality is very impressive. Everything feels so sturdy and heavy duty, also the design is absolutely stunning. Not to mention the beautiful 64mm burrs, long lasting motor, super solid interior/exterior components and overall heavy duty professional build. I’m so impressed, that I truly wonder why I didn’t buy the Mazzer right at the beginning, before the Mignon. At least now I know the difference. 

After I dialled in the anaerobic beans from Guji that i’m very familiar with, I was yet again mind-blown. Same recipe, same beans, but aroma way more pronounced, the taste much more complex – I really didn’t expect such difference. Honestly, I didn’t know this coffee can taste even better. I love the flavour profile these burrs produce, Mazzer did an excellent job with these. I’m yet again very happy with the choice I made. 

The Mazzer Mini is to my surprise also pretty quick. Some reviews said that it would grind 18g in about 20+ seconds, but it really takes only about 11-12 seconds for the (pretty dense) high altitude, light-medium roasted beans I’m currently using and the current grind setting. People often speak of retention – it’s 2-3g initially if that means anything to you. Once the gaps fill out, the number drops to negligible figures. The burrs are still new and need breaking in, but I’m not seeing almost any clumps at all. Definitely less than with the Mignon at the beginning. The grinds are very fluffy.

Grinding on the Mazzer Mini Electronic B is time based and as accurate as I dial it to be. I get 18g output most of the time once everything is set correctly. Dose accuracy depends on how good I calibrate the time according to the grind size. Occasionally, there’s a 0.1g difference between doses – nothing tragic. The grinder has two programmable doses – single press for single, double press for double. I can of course choose to set the parameters as I wish – single press can serve for a double dose as well. Holding the button will grind continuously. Grinding time can be adjusted by five hundredths of a second (0.05 seconds). If I want to stop grinding, pressing the button will stop the grinding cycle – easy. Some reviews say the grinder needs to be switched off in order to stop grinding, which again isn’t true. I really like the functionality of these features – really useful and easy to adjust.

Some owners upgraded their burrs to Super Jolly or SSP burrs. You’ve probably heard of motor stalling after upgrading to one of those more aggressive burrs, but I haven’t heard of it ever happening to anyone I know. So it perhaps really doesn’t happen that often. 

These are the everyday cons you’ll hear, but I assure you that these aren’t as much of a deal as you may or may not think. Getting past them rewarded me with a grinder that is by far superior to most in it’s class in both grind and build quality. It feels like a grinder that will serve the way it did on day one for the rest of my life. I really wish I could describe this experience better, but I can’t – it needs to be experienced.

If you have any questions about the Mazzer Mini (or any other comments), please let me know.

    Congratulations!

    Really want to try the difference you described cause I thought my current Mignon Silenzio is good enough. Can’t imagine Mazzer has that much improvement. It make me want to upgrade my grinder now as well! lol.

    Though I was told by a retailer that Mazzer is not ideal for home use because it can spill coffee and has relatively more retention than Mignon, also not very consistent on output. Do you see those problems?

      Hi Julian, thank you!

      I think the Silenzio is good enough, but you can definitely get more out of coffee with a better grinder. Improved grind quality from the bigger and well designed Mazzer burrs combined with slower rotation and less heat on the beans results in a better cup. While some notes were pretty subtle with the Silenzio, those flavours really punch through now – same coffee, same recipe but much bolder taste. It’s mind-blowing just how much better coffee can taste.

      I’ve read this typical retailer cons talk, but I haven’t heard of spilling coffee – that’s new! Haven’t noticed any spilling. I’ve heard some negative things about the Mazzer Mini as well and was worried about the choice I made – I’d probably send the Mazzer Mini back if it wasn’t good. But it’s really, really good. It’s very consistent. The initial retention is 2-3g, about the same range as Silenzio. Exchange (once the gaps fill out) is also pretty much the same. It definitely clumps less than the Silenzio and it’s pretty fast compared to what some reviews say.

      Please, let me know if you have any other questions about the Mazzer Mini. Many people said things about the grinder that simply aren’t true.

      Thanks!

      Julian, I just did some testing to give you some numbers – Emptied the hopper and grind chamber, threw 9,9g in and got 9,8g out. Then pushed out another 1,5g with bellows, meaning there’s about 1,5g exchange between doses. I’ve had worse numbers with the Silenzio. I’m not going to be single dosing, but these are good numbers.

      I hope that helps!

      I gotta say, it is surprising that there would be such a significant taste difference from the minion. That is one thing that constantly surprises me about this hobby…. There are so many apparently inconsequential details that wind up making consequential differences

      Thanks for sharing

        Hi Ardy,

        absolutely and well said, espresso is very finicky.

    Cheers mate for the quick and detailed response as always.

    That’s some good numbers. I’m not using Silenzio for single dose either. Kind of regret I didn’t get the Specialita cause the manual timer on Silienzio isn’t really user friendly. It’s hard to find the exact point to get the precise output.

    That’s the main reason I’m planning to change it. Mazzer does look like a good choice, especially it normally comes with Mini as a combo. I don’t have the mini now but really tempted to get it at some time point.

    Though read a few comments about the Mazzer so I’m not sure if it’s a good choice. Before reading your article and responses I was more interested in Mignon XL. But yeah now I’m more confident to get Mazzer instead of XL.

      Anytime!

      I actually considered getting XL as well, but I felt like going from Silenzio to the XL isn’t enough of an endgame upgrade for me personally. It is faster than Silenzio, quiet, with allegedly lower exchange between doses than Specialita or Silenzio, bigger burrs – these are some really good selling points. Depending on how the prices are where you live, I’d go with the Mazzer Mini instead. Everything about it is so proper and solid, you wouldn’t regret it. If you have any doubts or would like to know anything about the Mazzer, let me know. Just don’t get the combo with Lux D from La Marzocco, get the Mini from Mazzer. Lux D has smaller burrs and doesn’t have a timer.

      I hope that helps!

    May i ask if you also considered the very popular Niche Zero? If yes why did you decide against it?

      Hi Marc,

      I’m not a fan of the Niche Zero, but I have considered that grinder while I was still single dosing my Mignon some time ago. The one and only good thing about it for me are the Mazzer burrs. Yes, it’s very low on retention, which is really crucial for single dosing (and changing brew methods) and also the selling point/why it’s so popular for most home users. I think it’s also really ugly. I was decided that I didn’t want to buy a single dosing grinder, but it definitely wouldn’t be the Niche Zero if I really wanted one. If you’re in the EU, the price get’s closer to a proper grinder really quickly. I only drink espresso, so for my needs and from my perspective the Mazzer Mini Electronic B is by far a superior grinder.

      I hope that helps and thank you for asking!

    Glad to have come across this review, as I’m upgrading from my Rancilio Silvia + Baratza Sette 270 grinder, to a Linea Mini and have my eye on the Mazzer Mini B. I’d love to hear how you’re still finding this grinder months on?

      Hi,

      I stand behind what I said in the article, I’m really happy with the Mazzer and wouldn’t change it for anything else. I’ve had my eyes on the Super Jolly V Pro, but decided against it as it’s quite large. Even though the 64mm Mazzer burrs really are of a high quality, I’ve upgraded mine with SSP High Uniformity burrs recently and I’ll be updating this article shortly. This upgrade took the grinder even further above it’s pricetag. The grind time dropped from around 12s to 8.50-9s for 18-18.5g of light/light-medium beans, I haven’t experienced any stalls, the grinder sounds totally different while grinding with the SSP burrs and the coffee tastes from my perspective better. Just bear in mind this isn’t a single dosing focused grinder and never will be, only consider buying it if you’re absolutely sure you’ll be running it with beans in the hopper.

      I hope this helps!

    Hey there! Thanks for your review. After reading, I’ve decided to go with the Mazzer Mini as my first espresso grinder. Mainly because it looks beautiful and I know that it’ll produce a good cup of espresso—at a very reasonable price.

    I’ve also read that it’s hard to clean, as it must be recalibrated once it’s taken apart. What are your thoughts on this?

    I make 1-2 cups a day, and I don’t foresee myself cleaning it every week… but this is my only concern before hitting the buy button.

      Hi Shane,

      I’m glad that my article helped you choose a Mazzer as your first grinder, it’s a classic. I suppose you’ll be buying the most recent model and I think you’ll like the latest redesign as well. Cleaning it is easy, but make sure to buy some food safe vaseline to lube the threads after cleaning. I’ve cleaned mine only once when I upgraded the burrs, I don’t think I’ll be cleaning the grinder for another year from now. Cleaning it that often would be perhaps required more in a commercial environment, not at home.

      I’ve posted a review about the new 2022 Mazzer Mini A as well, have a quick read if you’d like.

      Thanks for asking!
