The Aeropress is the Swiss Army knife of coffee brewers. Durable, portable, and capable of producing everything from an espresso-style concentrate to a cold brew — all from a device that fits in a backpack. Unlike the V60 or French Press, the Aeropress adds a third variable to brewing: pressure. The act of pressing forces brewed liquid through a paper or metal filter, which both ends the extraction immediately and removes fine silt, resulting in a cup that is simultaneously clean and full-bodied — a combination almost impossible to achieve with any other method.
Of all the ways to use an Aeropress, one technique has become the clear favourite among serious home brewers: the inverted method.
Standard vs. Inverted: Why it Matters
In the standard Aeropress position, the brewer sits cap-end-down on your mug, and water is poured through the grounds immediately. Because gravity is always pulling liquid toward the cap, water begins draining through the filter from the moment it hits the grounds — shortening your steep time and giving you less control over extraction. The inverted method solves this completely. By flipping the Aeropress upside down with the plunger inserted, you create a sealed chamber. Water stays in contact with the grounds for exactly as long as you want. Nothing drains until you flip and press. This gives you the full-immersion experience of a French Press with the clarity of a paper filter.
What You'll Need
- Coffee: 17g, medium-fine grind (between filter and espresso — think fine sea salt)
- Water: 250ml at 93–96°C (just off the boil is perfect)
- Aeropress: Standard or XL, with a rinsed paper filter seated in the cap
- Scale & Timer: Highly recommended for repeatability
- Your mug: Pre-warmed with hot water if possible
The Inverted Method — Step by Step
Before you start: Place a paper filter in the Aeropress cap and rinse it with hot water directly. This removes the papery taste and pre-warms the cap so it seals better. Set it aside — do not attach it yet.
Step 1 — Set Up (Inverted Position): Insert the plunger into the wide end of the Aeropress chamber, just far enough to create an airtight seal — about 1cm in. Flip the entire assembly upside down so the rubber plunger end faces down onto your counter and the open end of the chamber faces up. This is your sealed brewing chamber.
Step 2 — Dose: Add 17g of freshly ground medium-fine coffee into the open chamber. Tap gently once to level the bed.
Step 3 — Pour (0:00 → 0:30): Start your timer. Pour 250ml of water just off the boil in a slow, steady pour directly over the grounds, ensuring every gram of coffee is fully saturated. The chamber should be almost full.
Step 4 — Stir (0:30): At 30 seconds, give the slurry 3–4 gentle stirs with the Aeropress paddle or a long spoon to ensure even, complete saturation with no dry pockets remaining at the bottom.
Step 5 — Steep (0:30 → 1:30): Attach the rinsed cap firmly onto the chamber — the filter facing inward, toward the coffee. The Aeropress is now fully sealed, and your steep timer runs. Let it sit entirely undisturbed until your timer hits 1 minute and 30 seconds.
Step 6 — Flip: With one confident hand on the cap and one gripping the chamber, carefully flip the Aeropress upright and position it directly over your pre-warmed mug. Work with a steady, controlled motion — you have a few seconds; there is no need to rush.
Step 7 — Press: Apply slow, even downward pressure on the plunger using your palm. Aim to take 25–30 seconds to press through the full column of coffee. If you meet significant resistance, your grind is too fine — ease up and go coarser next time. If the plunger drops with almost no resistance in under 15 seconds, your grind is too coarse. Stop the moment you hear a soft hiss of air — that is the signal that all the liquid has passed through and only dry grounds remain. Do not push further; it compresses the spent puck and forces bitter, over-extracted liquid into your cup.
The result is a clean, sweet cup with lower acidity than a pour-over and a richness that normally requires full immersion to achieve.
Adjusting the Flavour
The Aeropress is exceptionally responsive to small changes. If your cup is not quite right, adjust one variable at a time:
- Too sour or thin: Grind slightly finer, or extend your steep by 30 seconds.
- Too bitter or harsh: Grind slightly coarser, or reduce your steep by 30 seconds.
- Too strong or concentrated: Add 50–80ml of hot water directly to the cup after pressing to dilute to taste.
- Too weak: Increase your dose to 18–19g, or grind marginally finer.
- Gritty texture: Your paper filter had a tiny hole, or you are using a metal filter — switch to a fresh paper filter or double-filter.
Which Decimal Coffee for the Aeropress?
The Aeropress's paper filter makes it one of the most revealing showcases for single-origin coffees. Unlike the French Press, which leaves the coffee oils in the cup and creates a heavier, sometimes cloudy result, the Aeropress filter removes those oils entirely — leaving a clean, transparent liquid that carries the precise aromatic signature of the bean without interference. Our Chikmagalur Arabica, with its characteristic citrus brightness and floral top notes built from altitude and shade-growing, reveals dimensions in the Aeropress that you simply cannot access any other way. For a more approachable, everyday cup, our Arabica-Robusta blend gives you the crema-like richness and body of espresso without the machine.
