Conical vs flat burrs: what 55 real grinders show (2026)

Updated

Flat burrs are two rings that face each other. Conical burrs are a cone that turns inside a ring. Measured differences are small: on average conical burrs make more fines, but the overlap is large.

Conical burrs, cut openA drawing of a conical burr set seen from above and in front. A toothed cone sits inside a toothed ring. The front part of the ring is cut away, so the cone and the teeth inside the ring show. Coffee beans fall into the gap between the cone and the ring and travel down it.

Flat burrs, cut openA drawing of a flat burr set seen from above and in front. Two flat toothed rings face each other. The front part of the upper ring is cut away, so the teeth of the lower ring show. Coffee beans fall through the hole in the upper ring and travel outward between the rings.

Flat burrs

Two rings face each other.

What each burr is

A grinder crushes beans between two toothed metal parts, called burrs. One burr stays still. The other turns. The gap between them sets the grind size.

The two common shapes work in different ways.

Conical burrs

A cone turns inside a ring.

  • Beans fall into the gap between them and are cut as they move down.
  • They are common in hand grinders. The cone turns easily and can be compact.
  • In our data: 35 grinders, 17 hand and 18 electric.
  • The burr sizes we list run from 38 mm to 63 mm.

Flat burrs

Two flat rings face each other.

  • Beans pass between the rings and are cut as they move out to the edge.
  • In our data: 20 grinders, all electric.
  • The burr sizes we list run from 50 mm to 83 mm.

How beans become grounds in each burr

Beans go in at the top, one burr turns, and grounds fall out of the gap.

Flat burrs

How a flat burr grinder turns beans into groundsAn animated cross-section of a flat burr grinder. Beans fall from the hopper through the hole in the upper ring onto the turning lower ring, move outward between the toothed faces of the two rings, and leave at the rim as grounds that slide down a chute into a cup.

  1. Beans fall in from the hopper.
  2. One burr turns. It is the orange one. The other stays still.
  3. The gap between the burrs sets the grind size.
  4. Grounds leave the gap and fall into the cup.

Simplified: real grinders differ in how beans are fed and how grounds leave. The drawing shows the idea, not any one model.

Text version of the diagram

Conical: beans drop from the hopper into the gap between a fixed ring and a turning cone. The gap gets narrower as it goes down, so the beans are cut finer on the way. The grounds fall out at the bottom into a cup.

Flat: beans drop through the hole in the fixed upper ring onto the turning lower ring. They move outward between the toothed faces of the two rings. The grounds leave at the rim and slide down a chute into a cup.

What the cup difference is said to be

Many makers and sellers say flat burrs give a clearer cup. They say conical burrs give a rounder cup with more body.

Mahlkönig makes flat-burr grinders. Its own comparison table says flat burrs give Bright, clear, articulated flavors and conical burrs give Rounder, fuller body, less clarity (Mahlkönig, 2025-08-18).

Some reviewers say similar things about single grinders. Here is what the reviews we digest say:

  • Timemore Bricks 01S (40 mm conical, stainless steel (S2C040)): A reviewer says conical burrs mute clarity and acidity in bright light roasts. Pull & Pour
  • Varia VS3 Gen 2 (48 mm conical with a 38 mm inner cone, stainless steel): Reviewers taste sweet, rounded, body-forward espresso, ahead of the Sage Smart Grinder Pro. Kaffeemacher 2024-01-27
  • Niche Zero (63 mm conical, hardened steel): Some RedditRecs owners say light roasts work fine, others say they taste muddled. RedditRecs 2026-10-19
  • Eureka Oro Mignon Single Dose Pro (Flat, marketed as 65 mm (63.8 mm measured), semi-blind): A reviewer tastes silky, creamy espresso that combines clarity with depth. Kaffeemacher 2025-05-10
  • Turin DF83V (83 mm flat, DLC-coated steel): A reviewer says the stock burrs give shots with body, texture and decent clarity. The Coffee Chronicler 2024-05-03
  • Varia VS6 (58 mm flat, stainless steel (Supernova); 63 mm conical sets sold separately): The maker fits 58 mm flat burrs and offers 63 mm conical sets for the same body, and a retailer says swapping burr sets changed the flavor of the same coffee. Varia, Whole Latte Love 2025-07-07

The honest limit: the difference is small, and it depends on the grinder. America's Test Kitchen's tasters reported no discernible difference between coffee from a conical and a flat burr grinder (2025-07-09). In Jonathan Gagné's blind tasting, a flat grinder, the Baratza Forté, and a conical one, the Niche Zero, were both among the top scorers (2023-09-21). One retailer says swapping the burr set in a single grinder, the Varia VS6, changed the flavor of the same coffee. So the design of a burr matters, not only its shape.

What is actually measured

Labs measure the size of every particle in a sample of grounds. Kaffeemacher, a German test site, uses an imaging device, the Camsizer X2, and has measured over 70 grinders (2025-05-09).

The result is a curve: how much coffee sits at each size. Two words matter. Fines are the smallest particles, which extract fast. Kaffeemacher counts particles under 100 micrometres as fines. Boulders are particles much bigger than the grind you aimed for.

Figure 2 Diagram, not data

Fines, target size and boulders, drawn to one scale

A grind is never one size. Next to the size you aim for, a grinder makes fines and boulders.

Fines, target particles and boulders, drawn to one scaleA diagram, not data. Ground coffee particles drawn at one scale with a 1 millimetre scale bar. Many small orange fines are under half a millimetre, five brown target particles are about 1 millimetre, and two large slate boulders are about 2 millimetres.1 mm
  • Fines, under 0.5 mm. They extract fast and can add bitterness.
  • Target, about 1 mm in this drawing.
  • Boulders, about 2 mm. They extract slowly and can taste thin or sour.
Two sketch curves of particle size: one peak, and a peak with a second hill of finesA sketch, not data. The top curve has one peak. The bottom curve has a main peak and a smaller second hill on the fine side. Both axes run from finer to coarser particles.One peakfinercoarserA peak and a hill of finesfinercoarser

Makers say flat burrs make one peak and conical burrs add a hill of fines. This sketch shows that idea only.

Left: sizes from Coffee ad Astra's 2019 comparison of a flat and a conical grinder set for a filter grind with a peak near 1 mm. It reports fines below 0.5 mm and boulders near 2 mm (2019-04-07). Espresso grinds are finer. Positions are arbitrary. Right: a sketch, not measured data.

Text version of the diagram

Left drawing: many small fine particles, five target-size particles and two boulders, all at one scale, with a 1 mm scale bar. Right drawing: one curve with a single peak, and one curve with a main peak and a second, smaller hill of fines.

The biggest public data set is Jonathan Gagné's analysis of about 300 particle size distributions from 24 espresso grinders. Kaffeemacher supplied the data. He wrote that conical burrs appear on average less unimodal and less uniform, although there is a large overlap (Coffee ad Astra, 2023-09-21).

In his words: less unimodal means more fines, and less uniform means more boulders. He adds that one can easily find a specific flat burr that is less unimodal and less uniform than a specific conical burr. Larger burrs did not systematically grind more evenly either.

Mahlkönig, a flat-burr maker, says conical burrs make two peaks and that this matters most for espresso. It says the effect is far smaller for drip, French press and pour-over (2025-08-18).

Kaffeemacher published fines figures for three flat and one conical grinder in our data. The flat ones run from 19.6% to 32.2%. The conical figure (24.6%) sits inside that range. Settings and recipes differ, so these rows are not a ranking.

Our own data adds four things we can compare by burr shape: retention, noise, price and brew fit. The charts use the 55 grinders whose burr field names one shape: 35 conical and 20 flat. All 20 flat-burr grinders are electric, so each chart sets them beside conical electric grinders and shows conical hand grinders apart.

Left out: 3 grinders whose burr field names no clear shape. De'Longhi KG89 (its burr field names both shapes); Porlex Mini II (its burr field names no shape); Varia VS6 (its burr field names both shapes). They are in no chart below.

The honest limit: these charts compare groups of grinders, not burrs. Grinders also differ in motor, size and price. A gap between two groups does not prove the burr shape caused it.

Retention by burr type

Chart 1

Retention per grinder, in grams, by burr type

Among single-dose electric grinders, the middle figure is 0.5 g for conical (9) and 0.9 g for flat (7). The two ranges overlap. Hopper grinders keep more of both: 1.75 g and 2.95 g.

Retention is the ground coffee that stays inside a grinder. Each dot is the headline figure of our retention article and links to that grinder's review. A range is drawn at its middle with a thin line. Open dots were measured with an aid such as a bellows: they are drawn but left out of the median. A hopper grinder holds a tank of beans above the burrs. A single-dose grinder takes only the beans for one cup, and its retention matters more. 14 of the 55 grinders have no published retention figure and are not drawn. The Graef CM 800 is off the scale at about 8 g, marked with a break.

The ratings are our brew method ratings from published reviews: yes, limited or no. They rate the whole grinder, including its steps and speed, so they do not isolate the burr shape. Pour-over stands for filter coffee here. The limited rating counts as not yes.

Best conical and best flat grinder by budget

One pick per shape in each price band, delivered to Lithuania. The same rule runs for both shapes, so each band puts the best conical grinder beside the best flat one. A band can be empty for one shape.

Shop links may earn us a small commission. It never changes what we recommend. How we research

How we picked
  • Fit: the grinder's burr field names the shape, conical or flat.
  • Price: a shop has it in stock and delivers to Lithuania, with VAT and shipping included, inside the price band.
  • Reviewers: at least 2 reviewers recommend it, and at least 75% of the reviewers we list do.
  • Reason: the line under each name is quoted from that grinder's own review file about its burrs, with the sources that review cites for it.
  • Ranking: the share of reviewers who recommend it, then how many, then the owner rating from shop listings, then the lower delivered price. The first one in the band is the pick.
  • The same rule runs for conical and flat, so each band shows the best of each shape side by side.

Questions

What is the difference between conical and flat burrs?

Flat burrs are two flat rings that face each other, with the beans passing between them. A conical burr is a cone-shaped burr that turns inside a ring-shaped burr. In our data, 35 grinders have conical burrs and 20 have flat burrs. All 20 flat-burr grinders are electric.

Are flat burrs better than conical burrs?

Not by a clear margin. In Jonathan Gagné's analysis of 24 espresso grinders, conical burrs made more fines and more boulders on average, but the overlap was large. A particular flat burr can grind less evenly than a particular conical one. Judge each grinder by its own figures and reviews.

Is a flat burr or a conical burr better for espresso?

Our brew ratings lean flat. Espresso is rated yes for 16 of 20 flat grinders and 9 of 18 conical electric ones. Those ratings are for the whole grinder, including its steps and speed, not for the burr shape alone. Mahlkönig, which makes flat-burr grinders, says the difference matters most for espresso.

Do flat burrs and conical burrs taste different?

Sellers say flat burrs taste clearer and conical burrs taste rounder. Blind tests found little. America's Test Kitchen reported no discernible difference in the cup. In Gagné's blind tasting, a flat grinder and a conical grinder were both among the top scorers.

Do flat burrs have more retention?

Among single-dose electric grinders, the middle figure is 0.5 g for conical (9) and 0.9 g for flat (7). The two ranges overlap. Hopper grinders keep more of both: 1.75 g and 2.95 g. So compare single-dose grinders with single-dose grinders, and hopper grinders with hopper grinders.

Are flat burr grinders louder?

The middle reading is 81.35 dB for conical electric grinders (16) and 81.05 dB for flat (18). Quiet and very loud grinders appear in both groups. Hand grinders have no motor and are not in this comparison.

Are conical burr grinders cheaper?

Flat-burr grinders start at €149 delivered to Lithuania, and 7 of 18 cost €400 or more. For conical it is 1 of 28, and they start at €27.54.

Which burr is better for pour-over or filter coffee?

Espresso is rated yes for 16 of 20 flat grinders and 16 of 35 conical ones. Among electric grinders only, it is 9 of 18 conical. Pour-over is rated yes for 14 of 20 flat and 30 of 35 conical. Our ratings are for each grinder as a whole, so they do not separate the burr shape from the rest.
