Coffee Grind Size Chart - Golden Coast Coffee Company

A good bag of coffee can still make a disappointing cup when the grind doesn’t suit your brewer. Too fine, and water may struggle to pass through. Too coarse, and the coffee may taste thin or sour.

This coffee grind size chart gives you a starting point for your daily brew. Start with the suggested size, taste the result, and make small adjustments.

Coffee Grind Size Chart by Brewing Method

Brewing method	Starting grind size	What to look for
Cold brew	Coarse to extra coarse	Large, distinct particles that are easy to filter
French press	Coarse	A texture roughly like coarse sea salt
Percolator	Coarse	Grounds large enough to stay in the basket
Chemex	Medium-coarse	Coarser than a typical drip grind
Automatic drip	Medium	An even, sand-like texture
Cone pour-over	Medium to medium-fine	Start with your brewer’s recommended recipe
AeroPress	Medium-fine	Adjust to suit the recipe and steep time
Moka pot	Medium-fine, coarser than espresso	Use a moka-specific grind and do not tamp
Espresso	Fine	Fine particles that provide resistance during brewing
Turkish coffee	Extra fine	A flour-like powder

These descriptions are approximate. Grinder settings, roast levels, filters, and batch sizes all affect the result. A setting marked “medium” on one grinder may look different on another.

Follow your brewer’s instructions first, then use taste to guide your adjustments.

Why Grind Size Matters

Grinding coffee exposes more of its surface to water. Smaller particles generally release flavor faster than larger ones.

Grind size also changes how water moves through the coffee. Fine grounds can slow the flow in a pour-over or espresso machine. Coarse grounds usually allow water to pass through more easily.

The aim is to extract enough flavor for a satisfying cup without making it unpleasantly sharp, bitter, or drying.

However, grind size is only one part of the recipe. Your coffee-to-water ratio, water temperature, brewing time, roast level, and equipment cleanliness matter too.

Match the Grind to Your Brewer

Drip Coffee Makers

Start with a medium grind or the setting recommended by your brewer’s manufacturer.

If the coffee tastes sour and thin, try a slightly finer grind while keeping the coffee and water amounts unchanged. If it tastes harsh and drains unusually slowly, try a little coarser.

A weak cup may simply need more coffee. If the flavor is pleasant but too light, adjust the coffee-to-water ratio before making a large grind change.

French Press

A coarse grind is a straightforward starting point for French press. It helps limit the amount of fine sediment passing through the metal filter.

Finer grounds do not automatically ruin French press coffee, but they can make the cup muddier and the plunger harder to press. Press gently and never force it.

If the coffee tastes thin or sour, check your steep time and coffee dose. Then try a slightly finer grind if needed. Change one thing at a time so you can tell what helped.

Pour-Over Coffee

For a cone-shaped dripper, start with a medium to medium-fine grind. For Chemex, begin medium-coarse.

Watch how the coffee drains, but judge the result by taste. A fast brew that tastes sour may benefit from a finer grind. A slow brew that tastes harsh or drying may improve with a coarser setting.

Pouring technique, filter type, and the amount of coffee also affect drainage. Use the same recipe while testing grind changes.

AeroPress

Medium-fine is a useful starting point for many AeroPress recipes. The brewer also works with other grind sizes when you adjust the recipe.

Follow one recipe first, including its coffee dose, water amount, steep time, and pressing method. Then make small adjustments.

Use gentle pressure. If pressing is difficult, do not force it. Try a coarser grind on your next brew and check that the filter is positioned correctly.

Espresso

Espresso normally needs a fine grind. Small adjustments can noticeably change the flow and taste.

If a shot runs too quickly and tastes sour or thin, try grinding slightly finer. If it barely flows, try a little coarser.

Keep the dose consistent while adjusting. Uneven distribution can also cause water to find shortcuts through the coffee, producing an unbalanced shot even when the grind setting seems right.

Moka Pot

Use coffee ground specifically for a moka pot, generally coarser than espresso.

Fill the basket according to your brewer’s instructions and level the grounds without pressing them down. Do not tamp the coffee.

If the cup tastes harsh, check the heat and brewing technique as well as the grind. Grinding finer is not always the answer to getting a richer cup.

Cold Brew

Start with a coarse to extra-coarse grind and follow a recipe suited to your brewer. Larger particles make the finished coffee easier to filter.

Steep time depends on the recipe and whether you brew at room temperature or in the refrigerator. Keep those conditions consistent when comparing batches.

If the coffee tastes weak after dilution, try using less dilution water first. If the brew itself lacks flavor, adjust the coffee dose, steep time, or grind separately.

How to Adjust Your Coffee by Taste

Use these checks before changing your grinder:

What you notice	What to try
Sour and thin	Try a slightly finer grind or check whether the brew needs more time
Bitter or drying	Check roast level, brewing time, temperature, and equipment cleanliness. A slightly coarser grind may help
Pleasant but weak	Use a little more coffee or less water
Too strong but otherwise balanced	Use less coffee or dilute the finished brew
Pour-over drains very slowly	Try a slightly coarser grind and check the filter
Too much French press sediment	Try a coarser grind and pour gently

Sourness and bitterness are clues, not a diagnosis. Some coffees naturally taste brighter, while darker roasts can have more bitterness.

Keep the coffee and water amounts steady while testing a grind adjustment. Write down the setting you used and whether the next cup tasted better.

Whole Bean or Pre-Ground?

Whole bean coffee lets you adjust the grind to your brewer and grind just before brewing. That gives you more control over the result.

Pre-ground coffee is a practical option too. Choose a grind intended for your brewing method. A standard drip grind may not work well for espresso or Turkish coffee.

If you use a grinder at home, a burr grinder generally produces more consistent particles than a blade grinder. You don’t need to chase an exact dial number. Look for a repeatable setting that works with your coffee and brewer.

Choose Your Coffee, Then Fine-Tune the Grind

Start with coffee you enjoy, use the chart to choose a grind, and brew the same recipe a few times. Small changes are easier to judge than changing the grind, dose, and brew time together.
