1Zpresso · Conical burrJE-Plus
A dedicated espresso hand grinder built around a 47 mm DLC-coated conical burr and a uniquely fine 12.5-micron top-adjustment, producing classic syrupy, sweet shots and dosing directly into the portafilter via a magnetic catch cup.
The short version
The JE-Plus is 1Zpresso's espresso-specialist hand grinder: a high-quality conical burr with the finest top-adjustment in its class and a clever magnetic dosing system that suits single-espresso daily use.
The trade-off you must accept is slow grind throughput — expect 150–200 handle revolutions for a 20 g dose at espresso fineness.
Why people buy it
- 12.5-micron top-adjustment (40 clicks per rotation) gives unusually granular dial-in control for a hand grinder at this price
- Magnetic catch cup acts as a dosing bell that seats directly over common portafilter baskets — near-zero transfer mess
Why they don’t
- Notably slow grind throughput at espresso fineness — owners report 150–200 handle revolutions for ~20 g, roughly 2–3 times the cranks of competing models like the JX-Pro
The full tally
- 12.5-micron top-adjustment (40 clicks per rotation) gives unusually granular dial-in control for a hand grinder at this price
- Magnetic catch cup acts as a dosing bell that seats directly over common portafilter baskets — near-zero transfer mess
- 47 mm DLC-coated conical burr produces a classically sweet, creamy, syrupy espresso character that owners consistently praise
- Tool-free disassembly and reassembly without re-calibrating the burr; low maintenance burden
- Notably slow grind throughput at espresso fineness — owners report 150–200 handle revolutions for ~20 g, roughly 2–3 times the cranks of competing models like the JX-Pro
- Espresso-specific burr geometry means pour-over results are serviceable but not optimised; not the right choice if filter is your primary brew
- Availability has been intermittent — discontinued at least once, relisted; long-term parts/support continuity is uncertain

Worth knowing before you buy — Most owners say the decision is not "hand vs electric grinder" but "do I actually want to hand-grind every morning?" — if yes, this is the one; if no, save for an electric.
Known weak points — Handle wobble or cracking reported in early batches; screw-on burr carrier can strip with aggressive adjustment; motor seal failures in some electric retrofit attempts (not a factory issue but a community mod concern).

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners typically outgrow the JE-Plus on grind speed (not quality) — those pulling multiple daily shots migrate to an electric midrange like the Niche Zero or DF64. Cup-quality chasers who stay in hand grinders step up to the 1Zpresso J-Ultra (48 mm, 8-micron external adjustment) or a Comandante C40.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs pull syrup — naturals and classic medium roasts play straight into their character.

Common questions
Is the 1Zpresso JE-Plus still available to buy?
Yes — 1Zpresso relisted it on their direct store (1zpresso.coffee/product/jeplus/) after a period of discontinuation. Availability through third-party retailers has been intermittent; check the official store first.
What burr does the JE-Plus use?
Current production units use a 47 mm DLC-coated conical burr made in-house by 1Zpresso. Earlier models used an Italmill-made titanium-coated burr; 1Zpresso confirmed to customers that the supplier changed, though the cup profile is described as very similar.
How fine is the adjustment on the JE-Plus?
The top-mounted adjustment dial has 10 numbers and 40 clicks per full rotation, moving the burr 12.5 microns per click. This is among the finest stepped adjustments available on any hand grinder in this price range and is specifically tuned for espresso dial-in.
Can I use the JE-Plus for pour-over or filter coffee?
You can — the grinder is capable of coarser settings and the conical burr produces a consistent particle distribution. However, the burr geometry is optimised for espresso and produces a cup character (body-forward, lower clarity) that is less ideal for light-roast filter work compared to dedicated pour-over hand grinders like the 1Zpresso ZP6 Special.
Why does the JE-Plus grind slower than other 1Zpresso models?
The 47 mm espresso-optimised burr geometry requires more handle revolutions per gram at fine settings than the larger 48 mm all-purpose burr used in the JX-Pro or J. Owners consistently report 150–200 revolutions for a 20 g espresso dose, roughly 2–3 times the effort of the JX-Pro.
