Gifted an incredible machine but can’t afford a top tier grinder to match…what’s good enough? [$250]
If you don't mind turning the crank yourself, you can get incredible value from a manual grinder. I have a 1zpresso J-Ultra, and I'm so happy with it. Easy to clean, grinds 18g coffee in about 30 seconds, 8 micron adjustment means I can dial in any coffee to its sweet spot. Plus it is very quiet fir

Fully manual!!
Let’s just say, that unless I’m commenting on a Flair subreddit or something, I generally expect to get downvoted for expressing my preference for manual lever machines, but since you’re asking, here goes: It’s hard to beat the quality/price ratio with a manual setup. It would be arrogant of me to s

Would the X Ultra add anything to my collection?
I’ve had an X-Pro S for over 2 years (predecessor to the X-Ultra). I love the grinder. It’s a fantastic all-purpose grinder (as is the K). The burrs were slightly changed when they came out with the X-Ultra, but you get more for your $$$ with the Ultra - it has a magnetic catch cup and comes with a

Is it good? [1zpresso J ultra hand grinder]
I chose the J-Ultra because it offered the finest adjustment of any similar manual grinder. The steps are twice as fine as the JX-pro I used previously and works for all the various coffees I pull shots from. The external grind adjustment is easy to use. Everything takes a little longer than an elec

Struggling to get pressure on my pulls
^ This is a very 1st principle that is fundamental to understanding espresso, and especially the manual robot. You are pushing water through tiny gravel bits. if theyre big like rocks, the water rushes through, if they're tiny like clay not much water at all goes through. There is also the amount, m

Manual Espresso Grinder: Kinu M47 Classic vs 1zpresso J Ultra [No Budget]
I am extremely happy with my recent purchase of a J-ultra. It's about 30 seconds to grind the 17-19g I use in a shot. 1zpresso build quality is very nice, comes with a case and cleaning tools, super easy to use and the adjustment steps are suitably fine so you can dial in a ristretto or a normal sho

The Weekend Brew - What are you making this weekend? (May 2026)
Turkish grind is the finest of all coffee types (literally powder), so it really puts grinders to the test. Honestly, manual grinders give you the best bang for your buck for Turkish coffee. Check out the 1Zpresso J-Ultra or a classic Sözen hand mill. If you really want an electric grinder, you'll n

Gifted an incredible machine but can’t afford a top tier grinder to match…what’s good enough? [$250]
Don’t go for the hand grinder if you don’t like coffee, otherwise, you’ll be fine. I have an encore espresso and a 1zpresso j uktra, I love them both but unless I’m just making coffee for the sake of waking up, I’ll always find grinding by hand worth it. My only difficulty is that I have to calibrat

How good must be the grinder for mokapot?
Far more forgiving. Moka pot isn’t as dependent on the coffee bed for providing resistance. There’s barely that much pressure anyway, even with a Brikka. I‘m not saying that a cheap blade grinder, or a Javapresse clone or a Hario Skerton, is going to be good enough, either. Using a good grinder with

Profile cup Xultra vs Kultra?
They’ll be quite similar. K has 48mm heptagonal burrs X has 40mm heptagonal burrs They’re so similar that any superiority between the two might be down to the coffee you’re grinding. You might prefer one coffee with the X, and the K might bring out a quality in a different coffee that you really lik
