Turin DF54: Grind Settings for Espresso and Filter

17 for a light-roast espresso. 43 for an AeroPress. 90, the grinder's ceiling, for a French Press. The Turin DF54 isn't adjusted with clicks: you turn the collar and read a number from 0 to 90, where 0 is the finest.

The DF54 is an electric single-dose grinder with 54mm flat steel burrs, built for espresso but with enough range for most of filter. It's the same machine sold as the DF Grinders DF54, MiiCoffee DF54, or G-IOTA: same body, same burrs, same curve. Retention under 0.1g and a bellows to clear the chamber, so what it grinds is what comes out. Turin positions it as an espresso grinder, and the fine end of the curve agrees: it reaches down to 110µm, finer than you'll ever need.

That doesn't lock it into espresso. The DF54 reaches up to 900µm, which covers espresso through Chemex with room to spare. The one method where it comes up short is French Press: 900µm is a notch below the ideal coarse grind, and you'll notice. Better to say so up front. For everything else, the 54mm flat burrs give a uniform grind with few fines.

This guide gives you the exact number for every method and roast level. If you're coming from a Baratza Encore ESP looking for single-dosing and less retention, the DF54 is a natural jump. If your filter reference is the Fellow Ode Gen 2, you'll see the DF54 holds its own in V60 and AeroPress. And compared to the Eureka Mignon Specialità, the difference is focus: the Mignon is espresso-first with some filter, the DF54 splits the two worlds more evenly.

Quick Reference Table

Starting points are for a light-roast washed coffee. How much to add for medium or dark depends on the zone of the dial, because the curve isn't linear: on espresso, medium is 19 and dark is 24; on filter, adding 2 or 3 numbers is enough. Each section gives you the exact number by roast.

How the Setting Works

The DF54 has a continuous collar: no stops, no clicks, the upper burr rises or lowers smoothly as you turn. To give you a number, we use a 0 to 90 scale, the same one you see in Coffee Master.

• 0 is finest, 90 is coarsest. A lower number, finer grind. A higher number, coarser.
• The movement is continuous. Nothing stops you from stopping between two numbers. On espresso this matters, because each whole number shifts the grind about 12µm and sometimes you need half of that.
• The useful travel reaches 90 (900µm). Past that the collar keeps turning, but the burrs are so far apart the grind stops being usable.

To find zero, turn the collar toward finer until you hear the burrs touch. That's your origin. From there, count numbers toward coarse. Factory calibration is usually fine, but it's worth checking zero on a new unit or after a deep clean.

The DF54 is single-dose: you load only the beans for one brew, there's no reserve hopper. Because the burrs are flat, beans bounce a bit when you start (popcorning). A bellows or covering the throat as it starts reduces the bounce and steadies the grind.

Espresso

It's the method the DF54 was built for, and where the 54mm flat burrs shine most. The espresso zone runs from 13 to 30, with most recipes between 17 and 24.

• Light specialty roast: 17.
• Medium roast: 19.
• Dark roast: 24.

Target time: 25 to 32 seconds for 18g in and 36g out, depending on the recipe. If the shot runs in under 22 seconds and tastes sour, go down a number (finer). If it drips past 35 seconds and tastes bitter, go up one.

Two things worth knowing on espresso:

• Each number is about 12µm. It's decent resolution, but for fine adjustments take advantage of the continuous collar: move half a mark instead of a whole number when you're close to target.
• Minimal retention works in your favor. Since it doesn't hold coffee between doses, a change of number shows from the first shot. No need to purge beans before tasting the new setting.

AeroPress

The AeroPress accepts a wide range on the DF54, 30 to 59, and covers the three classic methods: standard, inverted, and concentrated.

• Light roast: 43.
• Medium roast: 51.
• Dark roast: 55.

Standard method: start at 43 to 45, 1:30 to 2:00 steep. Inverted method: drop to 38 to 42 for more body, 2:00 to 2:30 steep. Concentrated, espresso-style: 30 to 35, 1:00 steep, denser.

V60

V60 is where you see the DF54 does more than espresso. The flat burrs give a uniform grind in the medium zone, with few fines and good clarity in the cup.

• Light roast: 59.
• Medium roast: 61.
• Dark roast: 64.

Target time: 2:45 to 3:30 for 15g of coffee with 250ml of water. If it drains fast and tastes sour, drop to 57 or 58 (finer). If it stalls and tastes bitter, go up to 63 or 64.

In the V60 zone each number shifts the grind about 9µm, so you dial in with visible steps without fine-tuning between marks. A dedicated filter grinder like the Fellow Ode Gen 2 gives a touch more uniformity at coarse, but the difference in V60 is small.

Chemex

The Chemex's thick filter absorbs more oils and slows the brew, so you need to grind a bit coarser than for V60. On the DF54 you're in the 64 to 74 zone.

• Light roast: 69.
• Medium roast: 71.
• Dark roast: 74.

Target time: 3:30 to 4:30 for 30g of coffee with 500ml of water. The Chemex is forgiving on calibration, so you don't need to nail the number to pull a clean cup. If the flow stalls, go up 1 or 2 numbers; if it drains too fast, go down.

Moka Pot

• Range: 35 to 56.
• Light roast: 39.
• Medium roast: 47.
• Dark roast: 52.

Start at 39 for light. The Moka Pot wants a grind between espresso and fine filter, and the DF54 covers it with room to spare. If the moka hisses and spits coffee early (a sign of too-fine grind and a pressure blockage), go up 2 or 3 numbers. If it comes out watery and thin, go down.

French Press

Time to be honest: French Press is at the edge of the DF54. The grinder's coarsest grind is 900µm (number 90), and a French Press does best between 950 and 1060µm.

• All roasts: 90, the ceiling.

The coffee comes out drinkable, but with more fines in the cup than a grinder built for coarse. There's no room to adjust: 90 is the coarsest the DF54 goes, so you can't go further even if the taste asks for it.

How Roast Level Changes Your Setting

Same grinder, same method, same dose, and a light roast and a dark roast can still sit several numbers apart. Light roasts are denser and harder, they need more extraction surface, so you grind finer. Dark roasts dissolve faster and you grind coarser to avoid bitter notes.

On the DF54 the rule isn't a fixed number, because the curve changes slope by zone:

• On espresso the jump is bigger: from light (17) to medium (19) is 2 numbers, and to dark (24) is 7. Dark espresso wants notably coarser.
• On filter adding 2 or 3 numbers between light and dark is enough (V60: 59 to 64; Chemex: 69 to 74).
• In the flat zone around 500µm (number 43, the AeroPress) each number moves very little, so roast jumps translate into more numbers than in other zones.

If it gets confusing, use the exact number from each section instead of calculating deltas. The guide already did the math for you.

How to Dial In

The table is a starting point. To reach your recipe:

1. Pick the starting number for your method and roast.
2. Brew and taste. Brew time is a clue; taste is what matters.
3. Adjust 1 number at a time on filter, or half a mark on espresso.
4. Change one thing at a time. Don't move grind and dose together.
5. Write it down. Or use Coffee Master to log your brews automatically.

Most coffees land within 2 or 3 numbers of the starting point. If you're way off, check your water temperature or dose before moving the collar further.

Maintenance

The DF54 is single-dose with flat burrs, which simplifies cleaning but asks for consistency with static.

After every dose (5 seconds): give two or three puffs with the bellows to push out the coffee left in the chamber. Retention is minimal, but the bellows leaves the exit clean and keeps doses from mixing.

Once a week if you grind daily: brush the exit chute with a dry brush. Fines build up there and affect flow.

Every 2 or 3 months (deep clean): remove the top burr and clean both burrs with a brush and compressed air. Never use water or solvents. When you reassemble, check zero (turn until the burrs touch).

Two daily-use details:

• Static is the DF54's weak point. Flat burrs and low humidity produce a static charge that scatters the coffee. The RDT trick (a drop of water on the beans before grinding) removes almost all of it. In winter it's practically mandatory.
• Popcorning at startup is normal. Beans bounce on the flat burrs when you start. Covering the throat or using the bellows as it starts steadies the grind and keeps beans from flying out.
