What Grind Size for AeroPress? Best Coffee Ground for Brewing

If you’ve ever wondered what grind size to use for your AeroPress—or whether you’re grinding too fine or too coarse—you’re not alone. The AeroPress is beloved for its simplicity and clean cup, but nailing the perfect brew means getting the grind just right. Whether you're making a quick morning cup or experimenting with pressure brewing, your grind size plays a huge role in extraction, body, and clarity.

The ideal grind size for AeroPress is medium-fine, roughly similar to table salt or slightly finer than drip coffee. Most brewers use 17 to 20 grams of coffee, with a water temperature between 83°C and 90°C, and a total brew time around 1 to 1.5 minutes for balanced results.

What Is an AeroPress and Why Its Grind Matters

The AeroPress is a handheld, syringe-like coffee maker that blends immersion, filtration, and pressure brewing principles. Its design allows for a clean yet rich cup, combining the body of French press coffee, the clarity of pour-over, and some of the intensity of espresso—without needing high pressure.

Because it uses a combination of steeping and gentle pressure, grind size directly affects how quickly water flows through the coffee bed, how fully flavors are extracted, and whether you end up with over-extracted bitterness or under-extracted sourness. That’s why choosing the right grind is essential.

The Recommended AeroPress Grind Size

The ideal grind size for most AeroPress recipes is medium-fine. It should resemble table salt or be just a touch finer. This grind allows for a proper balance between extraction speed and resistance, giving you a clean, robust cup without clogging or excessive bitterness.

Do not use a grind as fine as for espresso or Moka pot brewing. While the AeroPress can handle slight pressure, it is not designed for true espresso extraction, and an overly fine grind may lead to over-extraction, slow drainage, or bitter notes.

How to Brew With AeroPress: Step-by-Step

Here’s how to set up and brew with the AeroPress using the parameters cited in the original guide:

• Grind: Medium-fine (similar to table salt), about 17–20 grams of coffee
• Water Temp: 83°C to 90°C (not boiling)
• Dose: One rounded AeroPress scoop equals ~14g; recipe uses 17–20g
• Bloom: First pour 50ml (~1/4 cup) of hot water, wait 45 seconds
• Stir: Stir the slurry 3 times to break up clumps
• Second Pour: Add another ~50ml to reach around 100ml total water
• Total Time: Start timer at 0:00; aim for 1 to 1.5 minutes total brew time including pressing
• Press: At 60 seconds, attach filter cap, gently invert AeroPress, and press down with steady pressure over 15–30 seconds

The entire process should take about 1.5 minutes from bloom to pressing, resulting in a clean and balanced cup. Adjust based on your taste preferences.

Tips and Tricks from the Original Guide

• Avoid too fine a grind—this isn’t espresso
• Metal filters can enhance crema-like texture
• The included AeroPress scoop holds ~14g, nearly 1.5x a standard coffee measure
• For stronger coffee, use 2 scoops (about 28g) with water to the #4 mark
• Hotter water is fine—even office hot water often doesn’t reach 100°C
• You can split water into two pours for better saturation
• Use a thick mug to handle the concentrated brew
• To clean faster, push grounds out through the filter before removing the piston
• No need to let the AeroPress dry completely before reassembling

Frequently Asked Questions

What is the best grind size for AeroPress?

The best grind size for AeroPress is medium-fine, similar to table salt or slightly finer than regular drip coffee. This allows for proper extraction without over-extracting or causing excessive resistance during pressing.

How fine should I grind coffee for AeroPress?

Grind your coffee to a medium-fine consistency for AeroPress. Avoid going as fine as espresso or Moka pot grind, which can lead to slow drawdown, bitterness, or clogging. A texture like fine sand or table salt works well.

What coffee-to-water ratio should I use for AeroPress?

The recommended coffee-to-water ratio is around 1:5 to 1:6, meaning roughly 17–20 grams of coffee to about 100ml (1/2 cup) of water. This yields a strong, balanced cup. You can adjust to taste.

What water temperature is ideal for AeroPress?

Ideal water temperature is between 83°C and 90°C. You don’t need boiling water—slightly cooler than boiling helps avoid over-extraction and burnt flavors while still extracting fully.

How long should an AeroPress brew take?

Total brew time—including bloom, stirring, pouring, and pressing—should be around 1 to 1.5 minutes. Start your timer when you add the first water, and aim to press down by around 60 to 90 seconds in.

Can I use a fine grind in AeroPress?

You can use a finer grind, but it’s not recommended for most brewing styles. A fine grind increases extraction speed and resistance, which can lead to over-extraction or difficulty pressing. It’s better for experimentation, not everyday brewing.
