1Zpresso K-Ultra Switzerland – Taiwanese All-Round Manual Grinder

You turn the external adjustment ring on the K-Ultra seven clicks further, each click firm and noticeable. That's a 0.14 millimeter grind size change – documented on the numerical scale. You fill the bean hopper, unfold the crank handle, and turn. The seven-sided K-Burr works quietly and smoothly, and the ground coffee falls into the magnetically held 40g catch cup. You briefly twist off the cup – done. This is 1Zpresso's K-Ultra: Taiwanese premium engineering with ease of use that was unthinkable in this price range just a few years ago.

1Zpresso is a Taiwanese manual grinder manufacturer that has positioned itself as a serious premium mid-range alternative to German brands like Comandante and Kinu since its founding. The model range is broad internationally (J-Max for espresso focus, K-Plus / K-Pro as all-rounders, Q2 as a travel grinder, JX-Pro for filter focus, K-Ultra as a modern all-round solution). Coffee Coaching Club currently carries the K-Ultra in its active assortment – the all-round variant with an external adjustment ring and folding handle. Other 1Zpresso models are not in our warehouse but can be checked upon request.

What makes 1Zpresso special

Three things. First: the external adjustment ring. Instead of internal grind adjustment (below the burr, as with Kinu and Comandante), the K-Ultra has an external, numerically labeled adjustment ring directly on the housing. This offers three advantages: instantly visible grind status, easy reproducibility through click counting, no disassembly for adjustment. Second: the "K-Burr" – a patented seven-sided conical burr geometry made of hardened stainless steel. Compared to classic hexagonal conical burrs, it delivers a different particle distribution, according to the manufacturer, with a more distinct bean characteristic. Third: ease of use. Folding crank handle for space-saving storage, magnetic 40g catch cup for twisting off, factory-calibrated grinder without further adjustment.

Understanding K-Ultra Technology

48mm K-Burr (seven-sided conical burr)
1Zpresso's own burr development made of hardened stainless steel. Seven instead of six edges on the conical burr result in a different bean-cutting geometry, which, according to the manufacturer, leads to brighter, clearer flavor profiles in the cup. Suitable for all brewing methods – from fine espresso to coarse French Press. Factory-calibrated and fixed by the 1Zpresso team, no manual axis adjustment needed. Designed for a grinding capacity of 100–200 kg of coffee with home use (manufacturer's specification).
External numerical adjustment ring
Grind adjustment directly on the housing – not inside the grinder as with many competitors. Over 100 clicks per revolution, each click corresponds to 20 micrometers (0.02 mm) of grind change. The numerical scale makes settings instantly visible and precisely reproducible – you can switch between espresso grind (e.g., click 30) and filter grind (e.g., click 80) and return to the exact same setting. Comparable to the ease of use of an electric grinder, without the electricity.
Magnetic 40g catch cup
The catch cup hangs magnetically on the lower housing – remove by a short twist, without a screw mechanism. Capacity 40 g (equivalent to two double espresso doses or one filter brewing dose for 500 ml). Clean pouring into portafilter or filter without shaking.
Folding crank handle
The handle can be folded to the side – without tools, without disassembly. Significantly reduces packing size, ideal for travel, hotel, office, or space-saving storage in kitchen drawers.

The 1Zpresso K-Ultra

1Zpresso K-Ultra Manual Coffee Grinder – from CHF 319.95

The K-Ultra is 1Zpresso's modern all-round manual grinder and the only 1Zpresso model currently carried by CCC. 48mm K-Burr (patented seven-sided conical burr made of hardened stainless steel) for grinding from espresso to French Press. External adjustment ring with over 100 clicks and 20-μm increments – numerical scale for exact reproducibility. Magnetic 40g catch cup for twisting off, larger capacity than the bean hopper. Folding crank handle for space-saving transport and storage. Burr calibrated and fixed by the factory. Available at CCC in two color variants:

  • Silver (CHF 319.95) – classic, light housing variant
  • Iron Grey (CHF 319.95) – more modern, matte dark variant

Technically identical grinding in both variants, the difference is purely in the housing finish. Suitable for manual lever espresso (Flair 58, Flair Pro 2), AeroPress, pour-over (V60, Chemex), French Press, and Cold Brew. For home baristas looking for a versatile manual grinder without specialization compromise.

Other 1Zpresso Models

1Zpresso internationally offers other models with different focuses: J-Max as an espresso-focused variant with finer adjustment at the lower grind end, K-Plus and K-Pro as all-round models from the older K-series, Q2 as a compact travel grinder, JX-Pro as a filter-focused variant with larger bean capacity and a coarser grind spectrum. These models are currently not in the CCC assortment. If you are specifically looking for one of these models, please contact us – we will individually check availability and delivery time.

Who is the 1Zpresso K-Ultra for?

The K-Ultra is suitable for home baristas who are looking for a versatile premium manual grinder for various brewing methods and prioritize ease of use over haptic premium engineering. It is particularly useful for changing workflows (espresso today, filter tomorrow): the external adjustment ring makes grind adjustment faster than with grinders with internal adjustment. Also useful for travel and hotels – the folding handle significantly reduces the packing size.

Those looking for espresso-focused premium engineering with full metal stainless steel construction and micron-precise adjustment: Kinu M47 Classic or Phoenix – the German endgame solution. Those looking for filter precision with a Nitro-Blade burr: Comandante C40 MK4. For a mid-range entry with good value for money: Timemore. For automatic grinding with single-dose precision (electric): Varia VS3 or VS4.

What goes well with it

The K-Ultra unfolds its all-round quality in a setup that takes both brewing worlds seriously. For manual lever espresso: Flair Espresso (Flair 58 as a premium lever machine, Flair Pro 2 as a classic lever). For pour-over: HARIO V60, Chemex. For AeroPress: AeroPress (fits directly with the K-Ultra). For espresso machines with a saturated brew group: Rocket EPICA as a home statement, La Marzocco Linea Mini.

For the scale: Acaia Lunar (espresso, with flow rate) or Pearl (filter). For precise kettles: Brewista Artisan or Varia AURA. For precision baskets: IMS Baristapro Nanotech. For airtight bean storage: Airscape (exclusive Swiss importer). For brew water setup: Apax Labs mineral profiles. For beans from our own roastery: CCC own roasts.

Frequent Questions

Which 1Zpresso models does Coffee Coaching Club carry?

Currently one active model: the K-Ultra (CHF 319.95) in two color variants (Silver, Iron Grey). Other 1Zpresso models such as J-Max, K-Plus, K-Pro, Q2, or JX-Pro are currently not in stock. If you are specifically looking for one of these models, please contact us – we will individually check availability and delivery time.

What is the "K-Burr" on the 1Zpresso K-Ultra?

The K-Burr is 1Zpresso's patented burr design: a seven-sided (heptagonal) conical burr made of hardened stainless steel with a 48 mm diameter. Classic conical burrs are usually hexagonal – the seven-sided geometry cuts the beans at a different angle and, according to the manufacturer, produces a different particle distribution, with a more distinct bean characteristic. Suitable for espresso, filter, and everything in between.

K-Ultra for espresso or filter?

Both. The K-Ultra is an all-round manual grinder and delivers both fine espresso grind and coarse filter grind in reproducible quality. For espresso on manual lever machines like Flair 58 or Flair Pro 2: typically in the lower click range (determine exact position depending on bean and machine). For pour-over (V60, Chemex): in the middle click range. For AeroPress: slightly coarser than espresso. For French Press / Cold Brew: in the upper click range. Specific values are individual, the scheme serves as a guide.

How many clicks per revolution does the K-Ultra have?

Over 100 clicks per revolution, each click corresponds to 20 micrometers (0.02 mm) of grind change. The numerical scale on the external adjustment ring makes every setting instantly visible and precisely reproducible.

What is the difference between K-Ultra and Kinu M47?

Both are premium manual grinders, but with different optimization. K-Ultra (CHF 319.95, Taiwan): external adjustment ring for instantly visible grind position, folding handle, magnetic cup, 48mm K-Burr, 0.02mm clicks. Kinu M47 Classic (CHF 374.95, Germany): internal grind adjustment with micrometer nut, 47mm conical burr with Black-Fusion, 0.01mm increments, entirely built in stainless steel. The K-Ultra offers more ease of use and refined marketing engineering, the Kinu more haptic tool quality and finer grind granularity. For travel and versatile brewing methods: K-Ultra. For endgame manual lever espresso: Kinu M47.

What is the difference between K-Ultra and Comandante C40?

Both premium manual grinders, but with different focuses. K-Ultra: all-round burr (espresso to French Press), external adjustment ring, folding handle. Comandante C40 MK4 (German manufacturer): filter-focused Nitro-Blade burr with special stainless steel, broad filter grind spectrum, classic internal adjustment. The Comandante is the filter specialist's choice, the K-Ultra is the all-rounder's choice. For almost exclusively pour-over: Comandante. For espresso plus filter from one grinder: K-Ultra.

How loud is the K-Ultra when grinding?

Standard for manual grinders – no electric motor, only mechanical grinding. You hear the clicking of the K-Burr and the soft hum of the ball bearings. Noticeably quieter than any electric grinder.

How long does the K-Ultra's burr last?

1Zpresso specifies a grinding capacity of 100–200 kg of coffee for general home use (manufacturer's specification). With a typical consumption of 10–20 g of beans per day, this corresponds to several decades. The burr is factory-calibrated and fixed by the 1Zpresso team – no shaky parts or burrs that loosen over time.

Does the K-Ultra have a travel case?

No hard case is included in the standard scope of delivery. However, the folding crank handle significantly reduces the packing size – the K-Ultra with its folded handle fits into a camera bag or a classic backpack outer compartment. If you need a dedicated case for travel, check out the Kinu M47 Traveler (CHF 234.95, with travel hardcase and compact aluminum construction).

Can I test the 1Zpresso K-Ultra live in Switzerland before buying?

Yes – subject to availability in the showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b). Bringing your own beans is welcome – the external adjustment ring and the mechanical grinding feel of the K-Burr cannot be conveyed through photos. A quick inquiry beforehand is sufficient.

How is the 1Zpresso K-Ultra delivered in Switzerland?

Standard shipping nationwide and to Liechtenstein in 2 to 4 business days. Click and Collect in Bern and Zurich. Free shipping from CHF 60.

Roastery Tip

The K-Ultra is an honest all-round choice that particularly excels with changing brewing workflows. Cozy Chocolate and Nutty Delight grind with clean particle distribution on the K-Ultra – the seven-sided K-Burr produces few fines, which is particularly evident in pour-over. Wild Peach as a light-roasted omniroast benefits from the numerical scale: you can document the grind position per bean and reproduce it exactly. One of many possibilities.
