K-Ultra, too difficult to grind

Big spectrum indeed. (I know you know all this, but I liked to add from here for OP.) I have two grinders, 1Zpresso J-Ultra and Mazzer Omega X Soft Burrs. You can’t go dead slow on a hand grinder anyways, you need muscle through it and try to keep a reasonable rpm. In my J-Ultra some dark roast are

Zp6 and J Ultra. Enough grinders for me.

Of course. ZP6 is the clarity king which is for filter coffee. I can't make espresso with ZP6 without pressurized baskets. J Ultra, on the other hand is the espresso grinder. Though 1zpresso did show the chart of J Ultra for filter coffee but I found brewing filter coffee with J Ultra may make my co

Eureka Mignon Single Dose vs Zero 65 vs Zero [$800]

Correct, I got the HG-1 Prime. I wanted larger, higher quality burrs without breaking the bank. And the reviews I found indicated it was what I was after: lots of body with a bit more clarity than usual for conical burrs. I'm not after hyper clarity in my coffee and usually make medium-dark espresso

J-Ultra v K6 v Lido OG [$250]

I actually disagree with this take. I personally preferred the K6 a lot more, and I like very sharp tasting light roast, funky processed coffee. I felt the J Ultra made everything too ‘same’. On that note though, the K6 failed me for the darkest of roasts, where it was simply bitter, while grinders

Best setup for single shot only [no budget]

If you go manual probably a 1zpresso j-ultra for a grinder. It is supposed to be doable when you use a power drill. For me the workflow would be too cumbersome though. Electric, check what's available in the 2nd hand market around you. I bought a Mazzer Mini recently for €80. I had a new exit chute

Kingrinder K6 or Timemore S3 ESP [175$]

Do you live in Uruguay by any chance lol. Here is quite expensive to get those products. I bought K6 for 40 bucks more than expected. Which isn't that much TBF now that I think . Other comment said it. You either get K6 or you go with 1Zpresso J-Ultra

Varia VS6 misalignment / axle run out issue !?

Just the stock 1 shim under the burr. That shim seems to be thicker than the 2 ones provided in the package by Varia along the replacement springs etc. The shots are not too good and I pulled about 14 already with the coffee I usually drink - Ethiopia light roast, so far they are worse in taste and

I just pulled my first actually good shot ever

I appreciate all the info! Yeah I knew the blade grinder wasn't going to be good but it worked for some sweet milk drinks for a while. I've only been really discouraged the last couple months since I splurged in a j-ultra and just couldnt get the dial in right. I use a scale to measure dose and shot

Zp6 and J Ultra. Enough grinders for me.

Interesting I'd say that the bitterness depends on the coffee as well there are certainly some beans that are not bitter at all using J-ultra, what I find annoying is the muddied cup like the flavours are not as clear and pronounced, but since my lack of experience I don't know if it's the part of t

How do you muster the willpower to hand grind first thing in the morning?

I roast my own coffee (Aillio bullet r2) and do light roasted coffee. I recently went on vacation to the beach and my Lagom mini stopped working on me. I bought a J Ultra on Amazon since it was the only option I could get delivered quickly and OMG that was not a pleasant experience. Hand grinding li
