Grinding
The grinder is the single most important thing you will buy, and the one most people buy last. We compare flat and conical burrs, electric and hand grinders, on the two measures that matter: grind consistency and retention — how much of yesterday's coffee ends up in today's cup.
38 mm stainless burr · hand · espresso-capable
Out-grinds electric grinders costing three times as much, provided you accept the arm. The ESP burr reaches espresso fineness with real adjustment — which is not true of most hand grinders at any price.
Best for: One or two coffees a day, or a travel grinder that does not compromise.
≈ $80 / £70 / 75 €
48 mm burr · hand · external adjustment
A 48 mm burr set with external adjustment and 240 clicks, at a price where the competition offers 38 mm and internal dials. The finish is plainer than a Comandante; the grind is not far behind it.
Best for: Espresso at home from a hand grinder, without paying Comandante money.
≈ $110 / £90 / 95 €
40 mm conical · 40 espresso steps + 20 filter
The cheapest electric grinder that genuinely does espresso and filter without being bad at both. Forty fine steps in the espresso range is the whole point — and Baratza will still sell you a burr set for it in ten years.
Best for: Anyone pairing a grinder with a Gaggia Classic, a Dedica upgrade, or a Barista Express they have outgrown.
≈ $200 / £190 / 220 €
55 mm flat burr · stepless · near-zero retention
Stepless adjustment, 55 mm flat burrs and almost nothing left in the chute — the three things that separate a serious espresso grinder from a good one. It is quiet enough to use at six in the morning without an argument.
Best for: A Gaggia Classic, Lelit or Rancilio owner who has stopped blaming their technique.
≈ $450 / £380 / 400 €
39 mm nitrogen-hardened burr · hand · filter & espresso
The hand grinder others are measured against, and priced accordingly. Grinds better than electric grinders at twice the money, and asks for your arm every single morning.
Best for: One or two exceptional cups a day, travel, and anyone who values the object.
≈ $340 / £270 / 290 €
64 mm flat burr · filter only · single dose
64 mm flat burrs, near-zero retention and a footprint the size of a mug, built for filter and honest about not doing espresso. For pour-over it is the clearest grind you can buy at this price.
Best for: V60, Chemex, AeroPress and batch brewing, where clarity is the whole point.
≈ $345 / £275 / 300 €
The burr type decides how even the grind is, and it is evenness that makes an extraction repeatable from one day to the next.
Moving from espresso to filter demands a wide adjustment range and a hopper you can empty easily between two different coffees.
Even the most affordable burr model beats a blade grinder. It is the entry point that changes the cup most for the least money.
Burrs, without hesitation. A blade grinder shatters the bean into wildly uneven pieces: water runs past the big ones and over-extracts the fines, giving a coffee that is sour and bitter at once.
In grind quality, often yes at equal budget, sometimes better. In convenience, no: expect one to two minutes of effort per cup, which quickly discourages beyond a single coffee.
Not necessarily different, but able to go fine enough with tight steps. Many versatile grinders stop just above the zone espresso needs.
A brush-out every two to three weeks, a full clean once or twice a year. Oils go rancid and give a stale-coffee taste nobody blames on the grinder.
A little, flat burrs especially on long grinds. In home use the effect on the cup is marginal compared with grind evenness.
Several hundred kilos of coffee in home use, meaning years. A grind that has turned uneven with no change of setting is the sign they are dulling.
No. Spices, sugar and cereals clog or damage burrs, and some smells never fully leave.
The grinder is the best investment in the coffee aisle, ahead of the machine. Burrs are non-negotiable, adjustment fine enough for your method, and regular cleaning — the rest, conical or flat, is argued over by enthusiasts and barely noticed in the cup.
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
