1Zpresso Q Air

What it does well

Coarse grind quality is the headline. CoffeeGeek says the Q-Air's edge is grind quality at coarser settings, with "noticeably fewer fines than the Encore," and fewer than the KINGrinder P2. Fewer fines mean a cleaner cup from pour-over and French press, so BrewMark rates its coarse grinding at the top of the scale.

The internals are better than the price suggests. Coffee Chronicler says the steel frame, axle, bearings and burr set match 1Zpresso's pricier grinders, with only the outer plastic cylinder and catch cup cost-cut. CoffeeGeek agrees: the housing is ribbed plastic, but the internals feel rigid with little burr wobble. 1Zpresso lists 304 and 420 stainless steel, polycarbonate and wood.

It is light and quick enough for a single cup. Coffee Chronicler timed about 35 seconds for 15 g of pour-over coffee. CoffeeGeek reports 30 to 40 seconds for 18 g. Coffee Chronicler describes the resulting cups as having sweetness and body, with less clarity and acidity than 1Zpresso's K-Ultra.

Setting adjustments are repeatable. CoffeeGeek says the Q Air is just as precise as the pricier Q2 within its target range, because the two share a mechanism.

Where it falls short

Espresso is not what it is for. CoffeeGeek says it can reach "espresso-adjacent" fineness but results are inconsistent. Coffee Chronicler timed 60 to 75 seconds for 16 g with the short handle, and called the flavor "pretty mediocre" though "passable." That is why BrewMark rates it 0 for espresso.

Capacity is small. CoffeeGeek puts the practical limit at about 20 g, and notes that the KINGrinder P2 holds about 23 g. If you brew for two or want a full-size French press, you will be grinding in batches.

Static and plastic are the recurring complaints. Both reviewers recommend the RDT method, and CoffeeGeek is concerned about how the plastic body will wear. CoffeeGeek also finds the dial counts up as you go finer, which is unintuitive, and a user quoted on 1Zpresso's page says published grind-setting charts are wrong for newer batches, so verify before trusting any chart.

Who should buy it, and who shouldn't

Buy it if you travel or camp, brew a single cup of filter or AeroPress, and care about clean coarse grinds. It also suits a small kitchen.

Skip it if you brew espresso, make several cups at once, or want a hopper you can fill and forget. CoffeeGeek's reviewer considers the cheaper P2 the better value for most buyers.

How it compares

The KINGrinder P2 has a larger hopper, per CoffeeGeek, and is the reviewer's pick for most buyers. The 1Zpresso Q2 is the pricier sibling that shares the Q Air's adjustment mechanism, per CoffeeGeek.

The Baratza Encore is the electric benchmark CoffeeGeek compares against. It is easier to use, handles light espresso better and suits larger batches, though it produces more fines at coarser settings.

Owning it

1Zpresso gives a one-year limited warranty on materials and workmanship. CoffeeGeek says disassembly is tool-free, but the dial can be reinstalled with the zero point off, so calibrate after cleaning. Our hand grinder cleaning guide covers the routine. The store page lists the Q Air as in stock.
