AeroPress Coffee Brewing Guide

A practical AeroPress recipe

The AeroPress is one of the most forgiving ways to brew coffee at home. It can make a short, strong cup or a longer filter-style brew, and it responds quickly to small changes in grind, dose, water, and time.

This guide gives you a dependable starting point. It is designed for clean sweetness, moderate body, and repeatable results rather than competition tricks.

What you need

• AeroPress brewer
• AeroPress paper filter
• Grinder
• Kettle
• Scales
• Timer
• Mug or server
• Freshly roasted coffee
• Clean, good-tasting water

Scales matter more than most people think. Scoops are useful in a hurry, but weighing coffee and water makes it much easier to repeat a good brew.

Our starting recipe

This gives a full mug with good clarity and enough strength to hold up with milk, while still drinking well black.

Grind size

Start slightly finer than you would for a typical pour-over, but not as fine as espresso.

If the coffee tastes thin, sharp, or sour, grind finer. If it tastes dry, bitter, or harsh, grind coarser. Change one thing at a time and keep the recipe otherwise stable.

Method

Place a paper filter in the AeroPress cap and rinse it with hot water. This helps the filter sit flat and warms the brewer.

Fit the cap to the AeroPress and place it directly over a sturdy mug or server. Add 15g of ground coffee.

Start your timer and pour in 240g of hot water. Try to wet all the coffee evenly.

Stir gently 3–5 times, then place the plunger into the top of the brewer. Pull it up very slightly to create a seal. This slows the drip-through while the coffee brews.

At 2 minutes, begin pressing. Press slowly and steadily for 20–30 seconds. Stop when you hear the hiss.

Swirl the finished coffee before drinking. This evens out the brew in the cup.

How it should taste

A good AeroPress brew should taste clean, sweet, and balanced. You should be able to pick up the character of the coffee without it becoming thin or aggressive.

For our coffees, this recipe works well with chocolate-led, nutty, and balanced profiles. It is a strong everyday method for coffees like Engineered Espresso, Amber, and Decaf No. 1.

Adjusting the recipe

If the coffee tastes sour

Sourness usually means the coffee is under-extracted.

Try one of these changes:

• Grind slightly finer
• Increase the brew time to 2:30
• Use hotter water
• Stir a little more at the start

Do not change everything at once. Start with grind size, then brew time.

If the coffee tastes bitter

Bitterness usually means the coffee is over-extracted, or the grind is too fine.

Try one of these changes:

• Grind slightly coarser
• Reduce the brew time to 1:30–1:45
• Use slightly cooler water
• Press more gently

A hard plunge can push more bitterness and sediment into the cup. Slow, steady pressure is better.

If the coffee tastes weak

Weak coffee is often a strength issue rather than a brew quality issue.

Try using 16–17g of coffee with the same 240g of water. You can also reduce the water to 220g for a slightly heavier cup.

If the coffee tastes heavy or muddy

AeroPress coffee should have body, but it should not taste sludgy.

Try a coarser grind, a gentler stir, or a slower plunge. Make sure the paper filter is seated flat in the cap.

Shorter, stronger AeroPress

For a stronger cup, use this recipe:

Brew as above, then dilute with hot water to taste. This method is useful if you want something closer to a long black or a milk-friendly base.

It will not be espresso. The AeroPress does not generate the same pressure as an espresso machine. It can still make a concentrated, satisfying cup.

Brewing with milk

For milk drinks, use a stronger recipe.

Start with 18g coffee and 120g water. Brew for 1:30, press slowly, then add warm milk. This produces a more concentrated coffee base that will not disappear once milk is added.

For iced milk drinks, brew the same strong recipe and press it over a few ice cubes. Add cold milk after brewing.

Standard method or inverted method?

The standard method is safer, cleaner, and easier to repeat. That is what we recommend first.

The inverted method can give more control over steeping, but it also increases the chance of spills. Hot water and an unstable brewer are a poor combination, especially first thing in the morning.

If you do use the inverted method, keep the brewer low, fit the cap carefully, and flip with control.

Water matters

Coffee is mostly water, so poor water will flatten the cup. If your tap water tastes heavily chlorinated, hard, or dull, try filtered water.

You do not need to overcomplicate it. Start with water that tastes good to drink.

Cleaning

Push the used coffee and filter into the bin or compost. Rinse the rubber seal, chamber, and cap with warm water.

Avoid leaving old coffee oils on the brewer. They build up over time and can make fresh coffee taste stale.

A simple rule

The AeroPress rewards consistency. Use the same dose, water, grind, and timing until you understand what each change does.

Once the cup is balanced, adjust for preference. More coffee gives more strength. Finer grind gives more extraction. Longer time gives more depth, until it goes too far.

Start simple, taste honestly, and make small changes.
