AeroPress Original Coffee Maker

Before first use, wash the chamber, plunger, filter cap, stirrer, and scoop with warm water and mild dish soap, then rinse thoroughly. No special assembly is required — the AeroPress comes ready to use.

The AeroPress Original brews 1–2 cups (up to 10 oz) per press using whole or ground coffee with hot water. It is compatible with standard AeroPress paper micro-filters and most third-party metal reusable filters. Press only over a sturdy mug or carafe rated for hot liquids — do not press over thin or delicate glassware, which can crack under pressure.

Set a kettle to heat water in the range of 175–205°F (80–96°C). A standard electric kettle without temperature control will typically reach 205°F. If you don't have a thermometer, boiling water that has rested for 30–60 seconds off heat will be approximately 195–200°F — a good all-purpose starting temperature.

The AeroPress is compact and lightweight. No electricity is required. It can be stored fully assembled or with the plunger removed from the chamber. Avoid storing with the plunger compressed inside the chamber for long periods, as this can degrade the seal.

Standard Brew Method

AeroPress uses air pressure and micro-filtration to brew coffee in 1–2 minutes. Insert a paper filter into the filter cap and rinse it briefly with hot water — this removes any papery taste and pre-warms the chamber. Screw the filter cap onto the chamber and set it over your mug or carafe. Add one rounded AeroPress scoop (about 14–17g) of medium-fine ground coffee per cup. Pour hot water (175–205°F / 80–96°C) to your desired fill level and stir for 10 seconds. After a 30–60 second steep, insert the plunger and press down with steady, gentle pressure over 20–30 seconds. Stop pressing when you hear a hissing sound — this means all the water has passed through and the brew is complete.

Inverted Method

For more control over steep time, many brewers prefer the inverted method. With the plunger inserted about an inch into the bottom of the chamber, flip the AeroPress upside down so it sits on the plunger end. Add coffee and water, stir, and steep for your desired time. When ready, attach the filter cap (with wet filter), then carefully flip the whole assembly onto your mug and press. The inverted method prevents any drip-through during steeping.

Espresso-Style Concentrate

For a concentrated espresso-style shot, use a finely ground coffee and half the usual water volume. Press slowly and firmly. The resulting concentrate can be drunk as-is or topped with hot water for an Americano or steamed milk for a latte-style drink.

Cold Brew

AeroPress can also make cold brew concentrate in about 2 minutes rather than the usual 12–24 hours. Use room-temperature or cold water and fine-ground coffee. Steep for 2 minutes, then press over a glass of ice. The result is a smooth, low-acid cold concentrate.

Grind Size and Coffee Ratio

Medium-fine is the all-purpose starting point for AeroPress — similar to table salt. Finer grinds increase strength and extraction (use for espresso-style); coarser grinds produce a lighter, more tea-like cup. AeroPress is very forgiving: adjust grind size and dose to taste. Fresh beans ground just before brewing make the biggest difference in cup quality.

Water Temperature

AeroPress works across a wide temperature range. For lighter roasts and delicate single-origin coffees, 200–205°F (93–96°C) brings out bright acidity and floral notes. For medium and dark roasts, 175–195°F (80–90°C) produces a sweeter, less bitter cup. Experiment to find what works best with your specific coffee.

Filter Options

AeroPress paper micro-filters produce a clean, bright cup with no sediment. AeroPress-compatible metal reusable filters allow more oils and fine particles through for a fuller-bodied, French press-like result with more texture. Metal filters are available as an accessory and are dishwasher safe.

After Each Brew

Cleaning the AeroPress is one of its greatest practical advantages. After pressing, unscrew the filter cap and hold the AeroPress over a trash bin or compost. Push the plunger all the way through — it ejects the used coffee puck cleanly as a compact disc. Rinse the plunger seal and the inside of the chamber briefly with water. The plunger wipes the chamber nearly clean as it passes through, so extensive rinsing is rarely needed.

Periodic Deep Clean

Remove the rubber plunger seal from the plunger tip periodically and wash it with warm water and a small amount of dish soap. Wash the chamber and filter cap the same way. All AeroPress components are dishwasher safe on the top rack. Allow all parts to dry fully before storage.

Filter Cap

Rinse the filter cap after every use to prevent coffee oil buildup in the filter seat. If the cap develops a film over time, soak it briefly in warm soapy water and scrub with a soft brush.

Paper Filters

Paper filters can be rinsed and reused several times. After pressing, remove the used filter and puck together, rinse the filter under clean water, and place it back in the filter cap for the next brew. Discard when the filter develops tears or significant discoloration.

Storage

Store the AeroPress assembled or disassembled — either is fine. Avoid storing with the rubber seal compressed against the inside of the chamber for extended periods, as this can degrade the seal over time. If storing long-term, remove the plunger fully from the chamber.

Coffee Too Bitter or Too Strong

Use a coarser grind, lower water temperature (try 185–195°F), or reduce steep time. Also reduce the coffee dose or increase water volume. Bitter coffee is almost always over-extracted — coarser grind and shorter steep are the quickest fixes.

Coffee Too Weak or Sour

Use a finer grind, hotter water, a longer steep, or increase the coffee dose. Sour or under-developed flavors indicate under-extraction — finer grind and hotter water are the most effective adjustments.

Plunger Hard to Press / Resistance Too High

Grind is too fine, coffee dose is too high, or the plunger seal has dried out. Try a slightly coarser grind or reduce the dose by 1–2g. If the seal is the issue, dampen it lightly with water before inserting the plunger. Never force the plunger — slow, steady pressure over 20–30 seconds is correct. Forcing causes grounds bypass and bitter flavors.

Coffee Dripping Through Before Pressing

This is normal with paper filters if brewing in the standard (upright) position — a small amount of drip-through before pressing is expected. If excessive, ensure the filter is properly seated and the filter cap is fully screwed on. Switch to the inverted method to eliminate any pre-press drip entirely.

Plunger Seal Worn or Leaking

The rubber plunger seal is a wear part that typically lasts 1–3 years depending on use. If the seal feels stiff, cracks, or no longer creates a firm seal against the chamber walls, it's time to replace it. Replacement seals are available directly from AeroPress.

Paper Filter Tears During Press

Pressing too fast or too hard is the most common cause. Use slow, steady pressure — 20–30 seconds for a full press. Check that the filter cap is fully and evenly tightened. Avoid using damaged or very old filters.
