Hand coffee grinders: which one to buy

If you can only buy one thing to improve your coffee, make it a grinder. For filter, the KINGrinder K6 is my pick; for espresso, the 1Zpresso J-Ultra.

Coffee starts losing aroma as soon as it’s ground. That’s why a grinder at home is the purchase you notice most, and a manual burr grinder gives, for the same money, a better grind than an electric one.

What sets them apart is how finely you can adjust them (it matters above all for espresso), how much coffee fits per batch and the weight, if you’re going to travel with it.

What to check before buying

  • Which method. Filter and AeroPress work with almost any grinder on this list. Espresso needs very small adjustment steps.
  • Capacity. 20 g is enough for a large cup; if you make Chemex for several people, look for 25 g or more, or an electric one.
  • Weight and size. For travel, under 400 g.
  • Adjustment. External (turning a dial) is easier than internal (taking it apart).

My pick

I’d buy the KINGrinder K6: the fine, external adjustment lets you move from filter to moka or espresso without changing grinder. On a tight budget, the P2 makes good filter coffee. If you’d rather not turn a crank, look at electric grinders or read hand or electric.

Sources

I haven't tried all of these products in person. The data come from the manufacturer's website or, when I don't cite one, from the amazon.co.uk listing (each source says which). I write with the help of AI and check every figure against those sources. I don't publish prices because they change daily: the one that counts is the price you see on Amazon when you buy.
