AeroPress brewing guide.

Why AeroPress is different

Everything else in pour over depends on gravity and the filter to control flow. AeroPress adds active pressure from the plunger, which means you control extraction by time, grind, and immersion length — not by trying to manage water flow against gravity. That's why AeroPress is so forgiving: the variables you have to nail are fewer.

The James Hoffmann standard recipe

1. Setup. Filter in cap. Rinse with hot water to remove paper taste. Cap onto chamber. Place on a decanter or sturdy mug.
2. Add coffee. 15 g of medium-fine ground coffee into the chamber.
3. Pour (0:00). Start timer. Pour 200 g of water at 90°C in one go.
4. Stir (0:10). Five gentle stirs with the paddle or a spoon. Don't be aggressive.
5. Insert plunger (0:15). Push the plunger down just enough to create a seal — about 5 mm in. Don't press; just seal.
6. Wait (0:15–2:00). Coffee steeps in the chamber. Plunger seal prevents premature dripping.
7. Swirl (2:00). Gentle swirl to redistribute the bed.
8. Press (2:00–2:30). Steady press over about 30 seconds. Stop when you hear the hiss — don't press past it (extracts the dry puck and produces bitterness).

Inverted vs. standard

The inverted method (chamber flipped upside down, plunger inserted before coffee and water) prevents the early dripping that happens in standard orientation while coffee is steeping. Inverted's main appeal is longer contact times (2:30–4:00 steeps without worrying about water dripping out).

The downside is the flip — swapping orientation while the chamber is full of hot coffee is fiddly and risk-prone. The standard method with an early-inserted plunger seal achieves the same control without the gymnastics. World AeroPress Champions are split roughly 50/50; for daily home use, standard is the simpler default.

Grind size — wide forgiveness window

AeroPress is immersion-based, so the grinder produces less critical fines migration than in pour over. Medium-fine works for most recipes. Examples:

• Comandante C40: 16–20 clicks
• 1Zpresso JX: 50–65 clicks
• Niche Zero: 12–18 marks
• Encore: middle of the grind range

Variations worth trying

• Long brew, low temp. 17 g coffee, 220 g water at 80°C, 4-minute steep, 30 s press. Smoother, sweeter cup. Hoffmann variant.
• Concentrate. 17 g coffee, 80 g water at 95°C, 1-minute steep, fast press. Dilute with 150 g water in the cup. Two cups from one brew.
• Cold AeroPress. 17 g coffee, 200 g water at room temperature, 8-minute steep, slow press. Bright, low-acid cup.
• "Espresso style" with Prismo. 18 g fine grind, 60 g water at 90°C, 30 s steep, 20 s press. Concentrated, mild crema. Not real espresso but close enough for cappuccinos.

Common pitfalls

• Pressing past the hiss. The hiss is air escaping — the puck is dry. Continuing to press extracts bitter compounds.
• Skipping the filter rinse. Paper taste is more noticeable in AeroPress because contact time is shorter.
• Too coarse grind. Coarse grind in immersion produces under-extracted, sour cups. Medium-fine is the floor.
• Inverted flip spill. Practice the flip with cold water first. Wet, hot chamber and wet, hot table are an unhappy combination.

Frequently asked questions

What is the best AeroPress recipe?

James Hoffmann method: 15 g coffee, 200 g water at 90°C, stir 5×, seal plunger, wait 2:00, swirl, press 30 s. Clean, balanced cup.

AeroPress standard or inverted method?

Standard is faster and dominates competition. Inverted gives longer contact time but adds setup risk. Both produce excellent coffee; standard is the simpler default.

What grind size for AeroPress?

Medium-fine. Forgiving across a wide range because immersion handles fines well. Comandante 16–20 clicks; Niche 12–18 marks.

Can you make espresso with an AeroPress?

Not real espresso, but you can produce a strong concentrate. Fellow Prismo or AeroSpeed get closer to espresso-like results but remain concentrates, not true 9-bar espresso.

How long do AeroPress filters last?

Paper filters are single-use. Reusable metal filters (Prismo, Able Disk) last indefinitely but pass more oils — body closer to French press.
