What grind size should I use for drip coffee?

A medium to medium-coarse grind, similar to coarse table salt. On a Baratza Encore (40 settings), use 18–28. Extraction should take 4–6 minutes for 10 oz of water. If your coffee tastes bitter, go coarser; if sour or weak, go finer.

What grind size should I use for espresso?

A very fine grind, close to fine flour or powdered sugar. On a Baratza Encore, use settings 5–12. The ideal extraction time is 25–30 seconds for 1.2 oz (36 mL). If it runs faster than 20 seconds, go finer; if slower than 35 seconds, go coarser.

What grind size should I use for French press?

A coarse grind, similar to brown sugar or coarse sea salt. On a Baratza Encore, use settings 28–38. Steep for 4 minutes. A grind that is too fine will slip through the metal filter and make the coffee muddy and bitter.

Does grind size change with humidity or temperature?

Yes. In humid weather or winter, grounds tend to clump and slow extraction. You may need to adjust slightly coarser by one notch in humid conditions. Professional baristas dial in their grind every morning because atmospheric conditions affect particle behavior.

How much coffee should I grind in advance?

Ideally, grind only what you need for each session. Ground coffee oxidizes rapidly and loses its aromatics within 15–30 minutes. If you must grind ahead, store grounds in an airtight container and use them within 24 hours. Whole beans stay fresh for 2–4 weeks in a sealed container.

Coffee Grind Settings Guide: Dial In Perfect Extraction in 2026

Grind size is the most important and most misunderstood variable in coffee brewing. Exceptional beans with the wrong grind will produce a mediocre cup. Understanding grind size unlocks the full potential of every bean you buy.

Quick answer: Too bitter = grind coarser. Too sour or weak = grind finer. Match grind size to brew time: espresso (25–30 sec) needs very fine; drip (4–6 min) needs medium; French press (4 min) needs coarse; cold brew (12–24 hr) needs very coarse.

Why Grind Size Matters

When hot water passes through ground coffee, it extracts soluble compounds: sugars, acids, aromatic oils, and caffeine. Particle size determines the speed and efficiency of this extraction.

Fine particles: large surface area → fast extraction → risk of over-extraction (bitterness)
Coarse particles: small surface area → slow extraction → risk of under-extraction (acidity, weakness)

Every brewing method has a different optimal contact time, which is why each requires a different grind size.

Quick Reference: Grind by Brewing Method

Method	Grind size	Brew time	Visual reference
Espresso	Very fine	25–30 sec	Powdered sugar
Moka pot (Bialetti)	Fine-medium	3–4 min	Fine salt
AeroPress	Fine to medium	1–3 min	Granulated sugar
V60 (pour-over)	Medium	2–3 min	Fine salt
Chemex	Medium-coarse	4–5 min	Coarse salt
Drip coffee	Medium	4–6 min	Coarse sand
French press	Coarse	4 min	Brown sugar
Cold brew	Very coarse	12–24 hr	Coarse gravel

Espresso Grind: The Most Demanding

Characteristics

Espresso requires a very fine, uniform grind. Water at 201°F (94°C) passes through 18–20g of coffee in 25–30 seconds under 9 bars of pressure. The slightest grind variation changes the result dramatically.

How to Dial In

The timer method:

Start the shot and time it
Target: 25–30 seconds for 1.2 oz (36 mL, double espresso)
If under 20 seconds → grind too coarse → go finer by one notch
If over 35 seconds → grind too fine → go coarser by one notch

Visual cues:

Correct extraction: steady golden-brown stream, thick crema
Over-extraction: dark drips, very bitter taste
Under-extraction: fast, pale flow, sour, watery taste

Baratza Encore Settings for Espresso

The Baratza Encore is not optimized for competition espresso but produces acceptable shots:

Recommended range: settings 5 to 12
Typical starting point: setting 8
Adjust in single-notch increments

Drip Coffee Grind

Characteristics

Drip coffee (filter machine or pour-over) is the most forgiving method to dial in. Water drips slowly through the grounds over 4–8 minutes. The grind should be medium to allow steady flow without saturating the paper filter.

Recommended Settings

Baratza Encore: settings 18–25
Krups GVX231: settings 8–12
De'Longhi KG79: settings 9–14

Standard Recipe

Classic ratio: 2 oz coffee per 34 oz water
For 2 cups (10 oz): 0.6 oz (18g) of ground coffee
Brew time: 4–6 minutes

Pour-Over: V60 and Chemex

V60 (Hario)

The V60 is a manual pour-over method. It demands a slightly finer grind than drip coffee because extraction time is controlled manually by your pour speed.

Baratza Encore setting: 14–22 Brew time: 2 min 30 sec to 3 min 30 sec for 10 oz Technique: 30-second bloom, then circular pours

Chemex

The Chemex uses thicker filters that slow the flow. The grind should be slightly coarser than the V60.

Baratza Encore setting: 22–28 Brew time: 4–5 minutes for 17 oz

French Press Grind

Characteristics

The French press is an immersion method—no paper filter. Coffee steeps in hot water for 4 minutes, then a metal plunger holds back the grounds. The grind must be coarse to:

Prevent particles from slipping through the metal filter
Allow immersion without over-extraction

Recommended Settings

Baratza Encore: settings 28–35
Krups GVX231: settings 14–17
Hario Mini Mill: 8–10 clicks from closed

Standard Recipe

Ratio: 2.5 oz coffee per 34 oz water
For 10 oz: 0.75 oz (21g) of coffee
Technique: pre-wet with a little hot water, then fill, wait 4 minutes, plunge slowly

AeroPress Grind

The AeroPress is the most versatile brewer: extraction time can range from 1 to 3 minutes, so grind size varies by recipe.

Fast recipe (1 min): fine grind (setting 10–14 on Baratza)
Classic recipe (2 min): medium-fine grind (setting 15–20)
Inverted long recipe (3 min): medium grind (setting 18–22)

Special Grinds: Moka Pot and Cold Brew

Moka Pot (Bialetti)

The moka pot builds pressure through steam. The grind should be fine but not as fine as espresso—similar to table salt.

Baratza Encore setting: 10–16 Warning: a grind that is too fine can clog the filter and create dangerous overpressure.

Cold Brew

Cold brew steeps for 12 to 24 hours in cold water. The grind must be very coarse to prevent over-extraction.

Baratza Encore setting: 35–40 Ratio: 3.5 oz coffee per 34 oz cold water

How to Spot a Bad Grind

Taste Test

Taste	Problem	Solution
Very bitter, harsh	Over-extraction	Grind coarser
Sour, watery, weak	Under-extraction	Grind finer
Balanced, sweet, aromatic	Correct extraction	Keep the setting

Visual Test (Espresso)

Dense golden crema = correct extraction
Dark, thin crema = over-extraction
No crema or pale crema = under-extraction
