Coffee Grind Size Guide

Standard, coarse, espresso or whole bean? A simple grind size guide with starting recipes for drip, pour-over, French press and espresso.

By domus Admin ·

Quick answer: match the grind to how long the water touches the coffee. Short contact (espresso) needs a fine grind; long contact (French press, cold brew) needs a coarse grind; drip and pour-over sit in the middle. At Hearthfield, choose Standard for drip and pour-over, Coarse for French press and cold brew, Espresso for espresso machines, or Whole Bean if you grind at home.

Why grind size matters

Brewing is extraction: hot or cold water dissolves flavor from the coffee. A finer grind exposes more surface area, so flavor dissolves faster. A coarser grind slows it down. When the grind and the brew time don't match, you taste it:

  • Too fine for the method: the cup can taste bitter, harsh or drying, and filters may clog.
  • Too coarse for the method: the cup can taste thin, sour or weak.

The right grind is simply the one that makes the brew time and the taste land where you want them.

Coffee grind size chart

Brew method Grind texture Typical contact time Hearthfield option
Espresso machine Fine, like powdered sugar to fine salt About 25–30 seconds Espresso or Whole Bean
Moka pot Fine to medium-fine A few minutes on the stove Espresso or Whole Bean
Pour-over (cone) Medium-fine to medium, like sand About 2½–4 minutes Standard
Automatic drip machine Medium About 4–6 minutes Standard
French press Coarse, like sea salt About 4 minutes Coarse
Cold brew Coarse to extra-coarse 12–18 hours Coarse

Textures and times are general starting points. Your brewer's own instructions come first.

Starting recipes by brewer

Drip machine and pour-over (Standard grind)

Start with a 1:16 ratio by weight: 20 grams of coffee to 320 grams of water. That makes roughly one large mug. For pour-over, water just off the boil (around 195–205°F / 90–96°C) is a common starting point. If the cup tastes weak, use a little more coffee; if it tastes heavy, use a little less.

French press (Coarse grind)

Use about 1:15: 30 grams of coffee to 450 grams of water. Pour, stir gently, put the lid on and wait about 4 minutes, then press slowly and serve straight away so the coffee doesn't keep brewing in the pot.

Cold brew (Coarse grind)

Cold brew recipes come in two styles, and they aren't interchangeable. A concentrate often uses around 1:5 to 1:8 coffee to water and is diluted before drinking; a ready-to-drink recipe uses more water from the start. Steep in the fridge for 12–18 hours, then filter. Label the jar so you remember which one you made.

Espresso (Espresso grind or Whole Bean)

For a double basket, a common starting recipe is 18 grams in, about 36 grams out, in 25–30 seconds (a 1:2 ratio). If the shot runs fast and tastes sour, grind finer. If it runs slow and tastes bitter, grind coarser. Pre-ground espresso can't be adjusted after it arrives, so if you want to dial in your shots, choose Whole Bean and grind fresh.

Whole Bean or pre-ground?

Choose Whole Bean if you own a grinder, especially a burr grinder, and like to fine-tune. Choose a ground option if you want convenience and your brewer matches one of our grinds. Both are good choices; see whole bean vs. ground coffee for the trade-offs.

Troubleshooting your cup

What you taste Likely cause Try this first
Sour, thin, sharp Under-extracted Finer grind, or slightly longer brew
Bitter, harsh, drying Over-extracted Coarser grind, or shorter brew
Weak but balanced Not enough coffee Use a little more coffee for the same water
Muddy French press Grind too fine Use Coarse; pour gently off the top

Change one thing at a time and write down your coffee weight, water weight and time. That's how you repeat a cup you love.

Grind size and caffeine

Grind changes how quickly flavor and caffeine dissolve, but it isn't a reliable way to control caffeine. The amount of coffee you use, your cup size and the coffee itself matter far more. If you want less caffeine, change the coffee: try Half Caff Coffee or a decaf. Read more in how much caffeine is in half caff.

Frequently asked questions

What grind should I use for a drip coffee maker?

A medium grind. On our product pages, that's Standard.

What grind is best for French press?

Coarse. A fine grind passes through the mesh and makes the cup gritty and bitter.

Can I use espresso grind in a drip machine?

It isn't ideal. It can over-extract and slow or clog the filter. Use Standard instead.

Which grind should I choose if I'm not sure?

Standard works for most drip machines and many pour-over brewers. If you own a grinder, Whole Bean gives you the most flexibility.
