How to Use an AeroPress

The AeroPress is the easiest specialty-coffee brewer to learn. If you can boil water, weigh 17 grams of coffee, and follow a timer, you'll make a better cup than most cafés on your first try. This tutorial walks you through it from unboxing to drinking — no jargon, no skipped steps.

What's in the box

A new AeroPress includes the brewing chamber, the plunger (the cylinder with the rubber seal), the filter cap (the round screw-on piece with holes), a bag of paper filters, a scoop, a stirrer, and a funnel. You'll use the chamber, plunger, filter cap, and paper filters every brew. The scoop and funnel are optional once you start weighing coffee on a scale.

What else you need

  • A burr grinder. Coffee tastes wildly different ground fresh vs. pre-ground. A budget burr grinder (Baratza Encore, Wilfa Svart, 1Zpresso Q2) is the single biggest upgrade you can make.
  • A kitchen scale that measures in grams to one decimal place. Cup measurements are imprecise; weight isn't.
  • A kettle — gooseneck is nice but not required for AeroPress.
  • A timer. Your phone is fine.
  • Fresh whole-bean coffee — roasted within the last four weeks. Whole bean stays fresh; pre-ground goes flat in days.

The beginner's AeroPress recipe

Variable Value
Coffee 17 g, medium-fine grind
Water 250 g at 200 °F (93 °C)
Ratio 1:15
Method Inverted
Total time 1:30
Yield One 8 oz mug of coffee

Step-by-step brewing

  1. Boil and cool your water. Bring water to a boil, then let it sit off the heat for 30–45 seconds. That drops it to roughly 200 °F — the sweet spot for AeroPress.
  2. Weigh and grind 17 g of coffee. Set your grinder to medium-fine (table-salt texture). On a Baratza Encore, that's about setting 12. Grind right before brewing — not in advance.
  3. Assemble the AeroPress inverted. Push the plunger into the chamber so the rubber seal is about 1 cm in from the bottom (this is now the "top"). Stand the AeroPress on the plunger end. The opening at the top is where you'll add coffee.
  4. Rinse a paper filter. Place a paper filter inside the filter cap (don't screw it on yet). Pour a little hot water through it over the sink. This removes papery taste and pre-heats the cap.
  5. Add coffee and start the timer. Place the AeroPress on your scale, tare to zero, add the 17 g of coffee, and start a timer.
  6. Bloom (0:00–0:30). Pour 50 g of water over the grounds — just enough to saturate the bed. Stir gently with the included stirrer or a spoon for 10 seconds. Wait until 0:30. You'll see bubbles rise; that's CO₂ degassing from the coffee.
  7. Pour the rest of the water (0:30–0:45). Pour until the scale reads 250 g total. Stir 5 seconds to settle the grounds.
  8. Cap and flip (1:00). Screw the filter cap on. Place your mug upside-down over the filter cap, then flip the whole thing in one motion. The AeroPress is now sitting on the mug, plunger up.
  9. Press (1:00–1:30). Press the plunger down with steady, even pressure. Aim for 30 seconds. Stop when you hear a hiss — that's air leaving the chamber, not coffee.
  10. Drink and clean. Lift the AeroPress off the mug. Unscrew the filter cap. Push the plunger fully to eject the coffee puck into the trash or compost. Rinse the seal under tap water. Done.

The five small mistakes that ruin a beginner's brew

  1. Pre-ground coffee. Ground coffee oxidizes in minutes. Grind whole beans right before you brew.
  2. Wrong water temperature. Boiling water (212 °F) over-extracts and tastes bitter. Let it sit for 30–45 seconds before pouring.
  3. Skipping the scale. "One scoop" of coffee can mean anything from 12 to 20 grams depending on the bean. 17 g is the recipe target.
  4. Wrong grind size. Too coarse = sour, thin, weak. Too fine = bitter and hard to press. See the grind size guide if your first cup tastes off.
  5. Old coffee. Coffee roasted more than six weeks ago has lost its bright top notes. Look for a "roasted on" date on the bag, not a "best by".

Your next few cups

Once the standard recipe is consistent, change one variable at a time to find what you like:

  • Stronger: increase coffee to 18 or 19 g, keep water at 250 g.
  • Brighter: drop coffee to 15 g and use water at 205 °F. Works well with light-roast single origins like Banko Gotiti.
  • More body: use a metal filter instead of paper — gives a heavier mouthfeel at the cost of a little sediment.
  • Espresso-style: see the AeroPress espresso recipe — 20 g coffee, fine grind, 60 g water, slow press.

Beginner AeroPress FAQ

How long does it take to learn AeroPress?

One brew to get the mechanics, three to five brews to dial in a coffee. Most people are making café-quality coffee within a week of buying their first AeroPress.

Inverted method or standard method — which should I start with?

Inverted. It gives you more control over the bloom and prevents drips during the bloom phase. The "standard" method (chamber sitting on the mug from the start) is faster but lets coffee drip into your cup while it brews, which under-extracts the bottom of the bed.

Can I make more than one cup at a time?

An AeroPress brews 8 oz — one mug. For two mugs, brew a 1:8 concentrate (e.g., 25 g coffee, 200 g water), then dilute with hot water to taste. Brewing two AeroPresses back-to-back is faster than scaling a single recipe.

What if I don't have a scale?

Get one — they're $15. Until then: the included scoop holds roughly 11 g of medium-grind coffee. Use 1.5 scoops and fill water to the "4" mark on the chamber. The results will be inconsistent but drinkable.

How long does an AeroPress last?

Years with normal use. The rubber seal on the plunger eventually wears out (1–3 years of daily use). Replacement seals from Aerobie are inexpensive and snap on in seconds.

Why does my coffee taste sour?

Under-extraction. Grind finer, raise your water temperature toward 205 °F, or extend the brew time by 15–30 seconds. See the grind size guide for full troubleshooting.
