Coffee grinders beta · Zerno
Owners keep the Zerno Z2 as a sturdy, repair-friendly home grinder that pulls espresso they are happy with, though some who came from the Z1 say the step up was modest.
Build quality is clear praise. Owners describe it as solidly made and easy to work on for repairs, and one owner who also has a Niche-style P80 says the Z2 is the better-built of the two.
Only a few owners discuss value for money, and each of them is mixed. Owners who moved up from the Z1 say they like both, but for traditional espresso the Z2 did not feel necessary, and one says they could have kept the Z1 for good.
The Zerno Z2 is an electric coffee grinder that grinds one dose at a time. It is built in Chicago and has a front-facing dial and adjustable motor speed. It is for home coffee fans who want one grinder for both espresso and filter coffee and want to choose their burr set.

Large 80 mm burrs and a strong motor grind a dose quickly, even for fine espresso. With stepless settings from 0 to 2000 microns, you can make very small changes and go from espresso to coarse filter grinds. Only about a tenth to a fifth of a gram stays in the grinder, so you get out almost exactly what you put in. At about 10 kg it is heavy and stays put on the counter, but it is not easy to move around.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
What owners still enjoy is the machine itself. One owner picked the Z2 because it matched the size and build of their Cremina lever machine and looked easy to repair, and it fit their counter better than the EG-1. Another owner, who has both, prefers the Z2 for espresso and the EG-1 for pour over, and calls the difference very small either way.
The adjustment is mostly about expectations. One owner who also has a P80 finds the P80 easier to use day to day and the grind quality the same on both. On taste, the few owners who discuss it lean positive, but there are too few accounts to call it, and owners who stepped up from the Z1 describe the improvement as small.
Build quality is the one theme with a clear positive verdict. Owners describe a solidly made grinder, and one says it was designed so repairs are easy to do yourself, which was part of why they bought it.
The long-term record is thin. None of the supplied accounts describe a Z2 breaking down, wearing out, or needing repair, and none say how long they have owned theirs. That means there is nothing yet to report on what fails or how owners deal with it.
From 0 owner accounts that said how long they have had it. Own one? Add how long yours has lasted.
Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
9 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
The same owner, asked again at each point. Fills in as owners answer.
Two questions: how long you have had it, and anything you would like to say about it. Then we ask again as it ages. This helps our mission.

Before you buy one used, ask the seller: how old it is, whether it was ever repaired and by whom, and whether any of the parts above have been replaced. Ask to see it run. A receipt tells you the warranty start date; most makers honour the term only for the first owner.
