How to Brew AeroPress Coffee: The Complete Guide
How to Brew AeroPress Coffee: The Complete Guide
The AeroPress is one of the most beloved coffee brewers in the world - and for good reason. It's fast, forgiving, portable, and capable of producing exceptional coffee across a wide range of styles. Whether you want a concentrated espresso-style shot, a clean filter-style cup, or something in between, the AeroPress can deliver it.
This guide covers everything you need to know: the classic method, the inverted method, grind size, ratios, water temperature, and how to get the best results from your beans.
What Is an AeroPress?
The AeroPress is a manual coffee brewer invented in 2005 by Alan Adler. It uses air pressure to push hot water through a bed of coffee grounds and a paper or metal filter, producing a smooth, concentrated brew in under two minutes.
Unlike espresso, which uses 9 bars of pressure from a machine, the AeroPress uses gentle hand pressure - enough to produce a clean, low-acid cup with good body and clarity. It's particularly popular with specialty coffee enthusiasts, travellers, and anyone who wants excellent coffee without a large machine.
What You Need
- AeroPress brewer and plunger
- AeroPress paper filters (or a reusable metal filter)
- Burr grinder
- Digital scale (accurate to 0.1g)
- Kettle (gooseneck preferred for control)
- Timer
- Mug or server
- Freshly roasted coffee beans
Classic AeroPress Method (Step by Step)
The classic method is the standard upright position. It's simple, fast, and produces a clean, balanced cup.
Recipe
| Parameter | Value |
|---|---|
| Coffee dose | 15g |
| Water | 240g |
| Ratio | 1:16 |
| Water temperature | 90-94°C |
| Grind size | Medium-fine (finer than filter, coarser than espresso) |
| Total brew time | 2-2.5 minutes |
Steps
- Rinse the filter. Place a paper filter in the filter cap and rinse with hot water. This removes any paper taste and preheats the brewer. Discard the rinse water.
- Assemble the AeroPress. Attach the filter cap to the chamber and place it on your mug or server.
- Add coffee. Grind 15g of coffee to a medium-fine consistency and add to the chamber.
- Start your timer and add water. Pour 240g of water at 90-94°C over the grounds. Stir gently 3-4 times to ensure all grounds are saturated.
- Place the plunger. Insert the plunger just enough to create a seal. This prevents drip-through during the steep.
- Steep for 1.5 minutes. Let the coffee brew undisturbed.
- Press slowly. At 1.5 minutes, begin pressing the plunger down with steady, even pressure. Aim to finish pressing in 20-30 seconds. Stop when you hear a hissing sound - this means you've pressed all the liquid through.
- Serve immediately. The AeroPress produces a concentrated brew. Drink as is, or add hot water to taste.
Inverted AeroPress Method
The inverted method flips the AeroPress upside down during brewing, preventing any liquid from dripping through before you're ready to press. It gives you more control over steep time and is popular with enthusiasts who want a fuller-bodied result.
Steps
- Assemble inverted. Place the plunger into the chamber about 1cm and flip the AeroPress upside down so the plunger is at the bottom.
- Add coffee. Add 15g of medium-fine ground coffee to the chamber.
- Add water and stir. Pour 240g of water at 90-94°C and stir gently.
- Steep for 2 minutes. Let the coffee brew undisturbed.
- Attach the filter cap. Place a rinsed paper filter in the cap and attach it to the chamber. Do this carefully to avoid spills.
- Flip and press. In one confident motion, flip the AeroPress onto your mug and press slowly over 20-30 seconds.
- Serve immediately.
Grind Size and Coffee-to-Water Ratio
| Style | Grind Size | Dose | Water | Result |
|---|---|---|---|---|
| Concentrated (espresso-style) | Fine-medium | 18g | 60-80g | Strong, syrupy, good for milk drinks |
| Standard filter-style | Medium-fine | 15g | 240g | Clean, balanced, full-flavoured |
| Light and delicate | Medium | 12g | 240g | Lighter body, more clarity, suits single origins |
The AeroPress is highly forgiving - small changes in grind size or ratio produce noticeable but not dramatic differences. This makes it an excellent brewer for experimenting and developing your palate.
Water Temperature
Water temperature has a significant effect on AeroPress flavour:
| Temperature | Best For | Flavour Effect |
|---|---|---|
| 80-85°C | Dark roasts, reducing bitterness | Smoother, less bitter, slightly less complex |
| 88-92°C | Medium roasts, balanced extraction | Balanced sweetness and acidity, good body |
| 93-96°C | Light roasts, maximising clarity | Brighter acidity, more floral and fruity notes |
If you don't have a temperature-controlled kettle, boil your water and let it sit for 1-2 minutes before brewing. This typically drops the temperature to around 90-92°C.
Troubleshooting Common Problems
| Problem | Likely Cause | Fix |
|---|---|---|
| Sour or sharp taste | Under-extraction | Grind finer, increase steep time, or raise water temperature |
| Bitter or harsh taste | Over-extraction | Grind coarser, reduce steep time, or lower water temperature |
| Too much resistance when pressing | Grind too fine | Grind coarser or press more slowly |
| Drips through before pressing (classic method) | Grind too coarse or filter not sealed | Grind finer, or switch to inverted method |
| Watery or weak cup | Too little coffee or too much water | Increase dose or reduce water, or add less hot water when diluting |
| Papery taste | Filter not rinsed | Always rinse the paper filter with hot water before brewing |
AeroPress vs Other Brew Methods
| Method | Brew Time | Flavour Profile | Difficulty | Best For |
|---|---|---|---|---|
| AeroPress | 2-2.5 min | Smooth, versatile, low acid | Low-medium | Experimentation, travel, quick brews |
| V60 / Pour-over | 3-4 min | Clean, bright, nuanced | Medium | Single origins, clarity-focused brewing |
| French Press | 4 min | Full-bodied, rich, textured | Low | Those who prefer a heavier cup |
| Espresso | 25-30 sec | Concentrated, intense, complex | High | Milk drinks, concentrated shots |
| Moka pot | 5-7 min | Strong, concentrated, espresso-like | Low-medium | Stovetop espresso lovers |
Best Beans for AeroPress
The AeroPress works beautifully with a wide range of coffees. Its versatility means you can brew anything from a light Ethiopian single origin to a dark espresso blend and get excellent results.
- Smooth Operator Medium Roast: Our most versatile blend. The balanced, caramel-sweet profile shines in the AeroPress, producing a clean, full-flavoured cup with a smooth finish. Works equally well at standard and concentrated ratios.
- Kickstart Medium-Dark Blend: Bold and rich. At a concentrated ratio, this produces an espresso-style shot that works beautifully with milk. At a standard ratio, it's a full-bodied, chocolatey filter-style cup.
Both are roasted to order and dispatched within 24-48 hours. See our full coffee beans Australia guide for more options.
Frequently Asked Questions
What grind size should I use for AeroPress?
Medium-fine is the standard starting point for a classic AeroPress brew. It's finer than a French Press grind but coarser than espresso. If your brew is sour or runs too fast, grind finer. If it's bitter or hard to press, grind coarser.
How much coffee do I use in an AeroPress?
15g of coffee to 240g of water (1:16 ratio) is a good starting point for a standard cup. For a more concentrated brew, use 18g to 60-80g of water and dilute to taste. The AeroPress is forgiving, so adjust to your preference.
What water temperature is best for AeroPress?
88-94°C works well for most coffees. Use the lower end (88-90°C) for dark roasts to reduce bitterness, and the higher end (92-94°C) for medium and light roasts to maximise sweetness and clarity.
Classic vs inverted AeroPress - which is better?
Neither is objectively better. The classic method is simpler and faster. The inverted method gives you more control over steep time and prevents early drip-through. Start with the classic method and try inverted once you're comfortable with the basics.
Can I use a metal filter in an AeroPress?
Yes. A metal filter produces a fuller-bodied cup with more oils and fine particles, similar to a French Press. A paper filter produces a cleaner, brighter cup. Both are valid - it comes down to personal preference.
Can I make espresso with an AeroPress?
Not true espresso, which requires 9 bars of pressure. But you can make a concentrated, espresso-style brew using a fine-medium grind, 18g of coffee, and 60-80g of water. It won't have the same crema or intensity as machine espresso, but it's an excellent substitute for milk drinks when travelling.
