1Zpresso was founded in Taiwan by a team of coffee lovers with engineering backgrounds, set on solving a problem specialty coffee had lived with for years: manual grinders that couldn't match the consistency of their electric counterparts. Their answer was a line of hand grinders built around precision-machined adjustment systems rather than simple click-stops. Today 1Zpresso is one of the most respected names in manual grinding worldwide, trusted by home brewers and travelling baristas alike.
The 1Zpresso K-Ultra Manual Coffee Grinder blends precision, portability and premium materials into one of the most capable hand grinders 1Zpresso makes. Its specialised heptagonal "K Burr" and external adjustment ring with over 100 clicks give you the kind of fine control usually reserved for bench-top electric grinders, whether you're pulling espresso or brewing pour-over. This is manual grinding built to a standard that rivals plugged-in machines.
The 48mm heptagonal stainless steel burr is shaped to grind faster than a standard conical while keeping particle size consistent, unlocking clarity and sweetness across brew methods.
Over 100 clicks per rotation move the burr in 20-micron steps, so you can fine-tune between espresso, pour-over and French press without second-guessing the setting.
At 19.5 x 18.5 x 6cm and 700g, the K-Ultra folds down small enough to pack, without asking you to compromise on grind quality.
The twist-off catch cup holds 35–40g of grounds and detaches magnetically, keeping dosing and cleanup simple.
Stainless steel, aluminium alloy, wood and silicone come together in a grinder rated to handle 100–200kg of beans over its lifetime without burr wobble.
The grinder comes apart by hand for cleaning and goes back together without losing your calibration.
A cleaning brush, blower and carrying case are included, so the K-Ultra is ready to grind — at home or on the road — the day it arrives.
You're the brewer who wants one grinder to handle everything from a fast morning espresso to a slow weekend pour-over, without owning two machines. The K-Ultra is for someone who values precision but also wants to take that precision travelling. Dial it in once, fold it up, and take café-level consistency wherever your coffee goes — no plug required.
