Thought I would put a thread together to have a look at this interesting grinder, the Mazzer ZM manual. Mazzer have released this grinder in various models, this one has the manual adjustment and has been designed around brewed coffee. Unfortunately not being a huge brewed drinker, I bought this on a whim hoping that it would be great for espresso as well, especially with the ultra low retention alla the ek43. First impressions were really good, this is one hell of a solid grinder weighing in at close to 40 kg with excellent build quality and components more akin to mazzers premium range that they supply to la Marzocco. It has a 900w motor that spins at 900 rpm, it exceptionally quiet and has a lovely smooth start stop action. Being used to the clunk of the ek this really comes as a pleasant surprise. It’s fairly big but not r120 and ek big it’s 62 cm to the top of the hopper, however only 49cm high with the hopper removed. It’s 45 cm front to back and 25 at its widest. This came fitted with the 151 f burrs with a cut specific to brewed coffee, however I thought I would give them a go at espresso settings. I had to set them just off zero point to get a pour anything like espresso and even though the pour was fast, it had a juicy sweetness to it, something I have become used to from the ek43. That said the roast level of the Coffee I was using was not particularly light and as such I feel it would be impossible to get espresso out of lighter roasted coffee using the “f” burrs. Rather than mess around with the filter burrs I fitted a set of ti coated 151b burrs which are a straight replacement into this grinder. What a difference, slow syrupy shots are now acheivable and even at the finer settings the retention is very very low and with a little effort is pretty much zero. The adjustment mechanism although stepped, is so accurate and each step is such a minute distance that fine tuning this grinder is simple and repeatable. Chucked some yirg through it, dealt with them with ease and the resulting espresso through a standard L1 was blueberries, blueberries and more blueberries. I am going to get the SSP burrs for this grinder which should give me a marked improvement with what is already a great flavour profile. I intend to do a bit of a strip down to show how well this is made but for now here are a few photos.
