Review: A well designed and engineered, premium grinder - This could be the best espresso grinder out there for travel. Using it with Wacaco Picopresso and loving the resulting cups. Built like a tank. Interesting premium material choices. Magnetic catch cup works like a charm. Ergonomics and work flow is top notch. Best part is the grind adjustment system. It’s a well thought out design and works efficiently. Adjustment clicks are pure ASMR. Minor adjustments are possible for perfect dial in. Grind chamber can be dissembled and cleaned without any fuss. Cons: Heavy, because it is built like a tank. Though the handle, grip and engineering of this grinder is near perfect, hand grinding do need some effort and strength.

I cannot say just how much I enjoy this hand grinder. I have three other brands of hand grinder, all more budget friendly, and the quality between those and this J-ultra is night and day. Let us start off by talking about the build quality. The bearings and springs are clean and well machined. The grinder comes apart easily for cleaning and is a breeze to calibrate afterward. Said bearings are silent when you turn the crank, without beans, and the action is smooth once you do add your coffee beans. The clicks the dial makes are smooth but reassuring. The crank handle is well machined, and the locking mechanism is easy to use. The catch cup magnets are great. Strong enough to not detach accidentally in use but not so much that it hard to take off when you are ready to make your coffee. And finally, the grip is great and feels like it will not slip after a few months of use like I have had happen with other grinders. Moving on to functionality I will say that it is easy to crank this with even lighter roasted beans. Or as much as can be expected from a hand grinder and a light roast coffee at an espresso setting but I digress. While it is easy to crank it is still fast, under 45 seconds for me, on most coffees with an 18 gram dose in 49/51/54mm baskets and a little longer on 58 as I have to grind finer (about 55 seconds). The dial is quite nice and having 8 microns of adjustment is insane. I almost always change settings 3-4 clicks at a time if I am dialing in as I know that I can pull a shot at 30 seconds on one setting and one click may give me a 29 second shot. It is so granular that I might even get another 30 second shot (this could even come down to puck prep or temperature differences in your process). As such this allows you to dial in by taste a lot easier. Say you pull a shot at your desired time (I like 28-32 seconds) but something tastes just a little astringent or a little sour, one click could change the flavor ever so slightly without changing your time or yield by a noticeable amount. This amount of granularity is also nice with manual machines like levers (or picopresso or robot etc). It just makes pulling a shot that is "almost there" that much easier. It is hard to explain but if you run a manual machine, you know that they can be finicky. Flavor profile wise, I find I like this better than some of my electric grinders. It is very good at pulling more traditional shots (think thick and syrupy body) but it produces a lot of fines, so it is great with longer 4:1+ ratios as well as it doesn't encourage channeling like some of my other bur sets do. I do find that even if it is good at pulling traditional shots it does also highlight acidity in those shots. I tend to get good body but more up front acidity than astringency. That is, unless you push it too fine on too light of a roast. No ristrettos on ultra-light filter roast but that isn't a pleasant experience for me anyway. Now, the one thing that I miss about having a screw on catch cup is that it fit in my portafilter/dosing ring better. This cup has a very large diameter. But that is me nit picking. And the grinder, with the handle on, will tip over if you leave it standing up so remove the handle! I can't speak to longevity as I've only put about 3 kilos of coffee through it at this point, but I have other 1zpresso products that haven't given me any issues. If you think this grinder is for you, it is. I wouldn't hesitate.
