How to pour over Indian naturals and anaerobics
6 min read
Grind coarser than you would for a washed coffee (about 81–84 clicks on a K-Ultra for V60), use water at 90–93 °C, and pour in two or three calm pulses with little agitation. If the bed stalls or the cup tastes boozy and bitter, go coarser still.
Indian estates now make some wonderful naturals and anaerobic lots, full of berry, tropical fruit and wine-like sweetness. They are also a little tricky on paper. The fruit-dried bean is often more brittle, so it throws off more fines when ground, and those fines clog the filter.
Why naturals behave differently
- They extract quickly. The sugars and fruit compounds dissolve early, so a long brew tips into bitterness.
- They make more fines. Fines slow the drawdown and push extraction even further.
- Their flavour is intense. A slightly lower extraction often tastes cleaner and sweeter than a high one.
- Anaerobic and co-fermented lots can taste boozy or funky when over-extracted. Gentle brewing keeps them juicy.
| Washed | Natural | Anaerobic | |
|---|---|---|---|
| V60 grind (K-Ultra) | 78–81 | 81–84 | 84 or coarser |
| Water | 94–96 °C | 91–93 °C | 90–92 °C |
| Ratio | 1:15 | 1:16 | 1:16 to 1:17 |
| Pours after bloom | 3–4 | 2–3 | 2 |
| Target finish (15 g) | 3:00–3:30 | 2:45–3:15 | 2:30–3:00 |
Recipe: V60 for a natural
- Grind 15 g at 82 clicks. Tap the grinder to drop the fines into the cup, not onto your counter; they belong in the brew but you do not want extra.
- Rinse the paper well. Naturals show papery taste more than most coffees.
- Pour 45 g of water at 92 °C and give one gentle swirl. Bloom for 40 seconds.
- Pour to 150 g in a slow spiral, staying off the paper walls.
- At 1:10, pour to 240 g in one calm pour.
- Do not stir. Let it drain and aim to finish by about 3:00.
Tip: If the bed looks muddy and flat at the end, you had too many fines. Go 2 clicks coarser before you change anything else.
When the filter clogs
| Symptom | Likely cause | Fix |
|---|---|---|
| Drawdown stalls past 4:00 | Fines blocking the paper | Grind coarser, pour more gently, skip the stir |
| Boozy, heavy, bitter finish | Over-extraction | Coarser grind and cooler water (90–91 °C) |
| Muted fruit, tastes like cardboard | Paper taste or stale beans | Rinse the paper more, check the roast date |
| Sharp and sour | Too coarse or too cool | Come back 1–2 clicks finer, raise water to 93 °C |
| Great first sip, harsh as it cools | Too many fines in the cup | Coarser grind, lower ratio to 1:16.5 |
A flat-bottomed brewer or an AeroPress is more forgiving with these coffees. See how they compare in the AeroPress guide. For a tasting reset, the 46 method lets you tune sweetness and strength separately.

Questions
Why does my natural take so long to drain?
Naturals often produce more fines, which clog the paper. Grind coarser and reduce agitation.
Should I use cooler water for naturals?
Slightly. Around 90–93 °C tends to keep the fruit clean without making the cup sour.
Is a Chemex good for naturals?
It can be, but its thick paper makes clogging worse. Grind coarser than usual, around 97–100 clicks on a K-Ultra.
Why does my anaerobic taste like alcohol?
Some boozy character is part of the style, but a harsh one usually means over-extraction. Brew coarser, cooler and shorter.

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.
AeroPress for washed vs natural coffees
One brewer, two approaches. Push a washed coffee harder for clarity, and go gentler with a natural so the fruit stays sweet.
What are anaerobic and experimental coffees?
