AeroPress for washed vs natural coffees
5 min read
For a washed coffee, use 15 g at about 68–71 clicks on a K-Ultra, water near 95 °C and a 2 minute steep. For a natural or anaerobic, go coarser (71–74 clicks), cooler (88–92 °C) and stir less. Both use about 230–250 g of water.
The AeroPress is the most forgiving brewer most people own. It is immersion, so every gram of coffee sits in the water for the same time, and the press filters out most of the fines. That makes it a great way to taste the difference between processes.
Two starting recipes
| Washed | Natural / anaerobic | |
|---|---|---|
| Coffee | 15 g | 15 g |
| Grind (K-Ultra) | 68 light, 71 medium | 71 light, 74 medium |
| Water | 95 °C, 250 g | 90 °C, 230 g |
| Stir | 3 stirs at start, 3 before pressing | 1 gentle swirl only |
| Steep | 2:00 | 1:30–1:45 |
| Press | 30 seconds | 30 seconds, stop at the hiss |
Standard method
- Put a paper filter in the cap, rinse it, and fit the AeroPress on your mug.
- Add 15 g of ground coffee and level it.
- Start the timer and pour all the water in 10 seconds.
- Stir or swirl as the table says, then place the plunger on top about 1 cm in. This stops dripping.
- At the end of the steep, swirl once and press slowly for about 30 seconds.
- Stop when you hear a hiss. Pressing the last bit through adds bitterness.
Tip: Darker Indian roasts do well at 74 clicks and 85–88 °C. Hot water on a dark roast quickly turns smoky and bitter.
Why the difference?
A washed coffee is cleaner and more acid-forward. It rewards a slightly finer grind and more heat because there is less that can go wrong. A natural is loaded with soluble sugars and fruit flavours that come out fast. Pushing it hard can taste jammy at first and heavy or boozy at the end.
| Symptom | Likely cause | Fix |
|---|---|---|
| Sour and weak | Under-extracted | Grind 2 clicks finer or steep 30 seconds longer |
| Bitter, dry aftertaste | Over-extracted | Coarser grind, cooler water, press more gently |
| Very hard to press | Grind too fine | Go 3 clicks coarser |
| Coffee drips before pressing | No seal | Put the plunger in right after pouring |

Questions
Is the inverted method better?
Not necessarily. It stops early dripping, but the plunger trick does the same job with less risk of spills.
Can I make a strong concentrate for milk?
Yes. Use 18 g with about 100 g of water, grind finer, then top up with hot or cold milk.
Paper or metal filter?
Paper gives a cleaner cup. A metal filter lets oils and fines through for more body, which suits chocolatey Indian medium roasts.

How to pour over Indian naturals and anaerobics
Naturals and anaerobics extract fast and can choke a paper filter. A coarser grind, slightly cooler water and gentler pours keep the fruit clean.
How do you brew light roasts well?
Light roasts are dense and slow to give up flavour. Hotter water, a finer grind and a little patience turn sour cups into sweet, bright ones.
What grind size should you use?
Grind size decides how fast flavour leaves the coffee. Here is a chart for every brewer, how to adjust by roast, and how to fix a cup by taste.
How does processing change the flavour of coffee?
Washed, natural, honey, anaerobic, monsooned. What each method does to the bean and what it tastes like in the cup.
