1Zpresso model names sit close together, which is why people stall on which hand grinder to buy. This page stays with five lines the maker already separates by job: a travel Q, the smaller-burr X-Ultra, the pour-over ZP6, the all-method K-Ultra, and the espresso-focused J-Ultra.
We have not used a 1Zpresso. There are no tasting notes on this page. Every number is what the official page showed when we opened it on October 31, 2026. Those pages get revised, so open the same page again before you order.
If the grinder is going to live at home for daily pour-over, the one this site still points to first is the Timemore Chestnut S5 Pro. Use the 1Zpresso list when you already know which job the grinder has to do.
The short answer
- A lighter bag, and drip for one or two people → Q2 S. If the gram count matters more than a folding handle, look at the Q Air
- A smaller burr, with drip and espresso both adjusted from the outside → X-Ultra
- Pour-over, on a burr the maker describes as producing fewer fines → ZP6 Special
- One grinder that has to cover more than one brew method → K-Ultra
- The finest espresso clicks 1Zpresso publishes → J-Ultra
The official chooser still lists the J, JX-Pro S, JE-Plus, and X-Pro S, and it includes a click chart. This page stays with the five lines whose jobs are easiest to tell apart.
Numbers from the official pages
| Model | The job 1Zpresso assigns | Adjustment | Capacity | Weight |
|---|---|---|---|---|
| Q2 S | Travel size. A small burr aimed at drip | Internal. The Q Series is 30 clicks per turn, 0.025mm per click | 15–20g | 465g |
| Q Air | The lightest grinder in that same Q Series | Same as the Q2 S | 15–20g | 365g. The handle does not fold |
| X-Ultra | A smaller heptagonal burr, for drip and espresso | External. 12.5 microns per click | 25–30g | 590g |
| ZP6 Special | The maker says it produces fewer fines than other 1Zpresso grinders, and aims it at drip | External. 90 clicks per turn, 22 microns per click. 48mm hexagonal burr | 30–35g | 700g |
| K-Ultra | All-methods. The maker describes it as the larger burr | External. 100 clicks per turn, 20 microns (0.02mm) per click. Heptagonal burr | 35–40g | 700g |
| J-Ultra | Espresso. The finest click step in the 1Zpresso range | External. 8 microns per click. Coated 48mm burr | 35–40g | 670g |
Sources are at the end of the page. The Q Series travel copy says "465g." On the same page, the table assigns 465g to the Q2 S, 480g to the Q, and 365g to the Q Air. Use the table. The maker also says the Q and the Q Air use a newer heptagonal burr, described as easier to turn, and that this burr is not the one in the Q2 S.
Who each one is for
Taking it with you: the Q
1Zpresso describes the Q Series as the smallest and lightest line in the range. Capacity is 15–20g, which suits drip for one cup or two people. You adjust it from the inside. The scale is not a dial you can read from the outside.
Choose the Q2 S (465g) when you want a folding handle. Choose the Q Air (365g) when you want the lowest weight. The Q Air handle does not fold. On the official table, the Q Air body and catch cup are plastic.
A smaller burr, at home or in a bag: X-Ultra
The X-Ultra weighs 590g, holds 25–30g, and has a folding handle and a magnetic catch cup. The maker says the smaller heptagonal burr takes less force. Adjustment is external, at 12.5 microns per click, and the grinder is positioned for both drip and espresso. This site has no tasting that compares those two uses.
Fewer fines in a pour-over: ZP6 Special
The ZP6 Special uses a 48mm hexagonal stainless burr. The official description says it produces fewer fines than 1Zpresso's other grinders. Each click is 22 microns, a wider step than the K-Ultra or the J-Ultra, so the grinder sits close to a drip tool. Weight is 700g. The product page says Carlos Medina used one at the 2023 World Brewers Cup. We have not checked that competition record.
One grinder across brew methods: K-Ultra
The K-Ultra is the model 1Zpresso places in the all-methods slot. The external dial is 100 clicks per turn and 20 microns per click, and the manual says you can keep turning past one full rotation. Capacity is 35–40g and weight is 700g. The burr is heptagonal. The product page opened on October 31, 2026 did not give the burr diameter in millimeters. Espresso sits inside its range. If you are comparing click size alone, the J-Ultra's published step is finer.
Espresso clicks: J-Ultra
The J-Ultra is the 8-micron step that 1Zpresso calls the finest in its range. The burr is a coated 48mm, and the maker describes the grinder as built for espresso. Weight is 670g, capacity is 35–40g, and the catch cup is magnetic. A finer click does not remove the work of grinding espresso by hand every morning. If that is the plan, read how to choose an electric coffee grinder and hand vs electric grinders. The only hand grinder whose official espresso range this site has checked is the Chestnut S5 Pro. This article does not copy a recommended J-Ultra click number.
A click number does not travel to another grinder
"Setting 6" is a different grind once the burr and the width of each click change. Inside 1Zpresso, the Q series step of 0.025mm, the X-Ultra's 12.5 microns, the ZP6's 22 microns, the K-Ultra's 20 microns, and the J-Ultra's 8 microns are separate scales. The Chestnut S5 Pro's 15 microns per click is a different scale again. The order of grind size by brew method is in the coffee grind size guide.
The hand grinders this site recommends first
1Zpresso is not in this site's order of picks. Those roles stay as they are: the Chestnut S5 Pro when you want a pour-over setting that lives on the counter, and the EPEIOS Essence Go when you want light turning or a grinder you can take apart and carry. The side-by-side is Timemore S5 Pro vs EPEIOS Essence Go. The four things to check on a first grinder — burr size, adjustment, weight, and where it lives — are in how to choose your first hand grinder.
