This recipe is best for Medium roast, any origin

t’s a technical recipe because you need to control your water speed very well in order to brew according to different water pressures. It’s about the technical skill and details of hand dripping and not just about the numbers of weight and volume.

Immersion, Kono dripper

Grinding Size

Commandante 34, around 9

Dose of coffee

18 g

Water

89-92 °C
270 ml

Total brewing time

2:15-2:30

Coffee water ratio

1:15

Detailed Guidance

1. Pre-infuse 40g water for 25-28 seconds
2. Gently pour in a circular motion starting in the center and going outwards you to a diameter of around 2cm. Pour in a steady flow and make sure the coffee grounds rise at the same rate as the water volume in the dripper until 140g water.
3. Wait until most of the water drips into the cup but don’t allow the coffee bed to be completely dry.
4. Then repeat step 2 until 240g total water.
5. Repeat step 3.
6. Move the mouth of the kettle lower, closer to the grinds, in order to lower the water pressure. Pour only in the center until 270g.
7. Wait for all water to finish dripping.
Tip: do not preheat the server before brewing and make sure to pre-wet the paper filter first.

How to grind coffee?

Grind setting 1 to 10

The grind setting below is from our volunteer Carlos @chaosinrye and @fatima_quest. This is only a draft version. You can help us improve it, refine it, polish it, and more. Please give us feedback on the Discord channel, thank you for your great help. We would like to design a grind setting converter to make it easier for coffee lovers around the world. Can you help?

Screen Shot 2021 01 14 at 7.48.45 PM1. Extreme fine grinding

<200-200 µ – Extra Fine (I) (confectioners sugar)

it is so fine that is almost impossible to filter/separate, like a powder, usually the finest grading in your grinder. Used for Ibrik/Turkish method because it “dissolves”; in pour-over can clog the filters. The substances extraction is extreme and can lead to a more bitter taste.

2. Finest grinding

300 µ – Fine II (flour)

almost a powder, a little more boulder. Can be used in Ibrik/Turkish coffee, and for some coffee beans in Moka Pot and espresso. The substances extraction is very high but has less surface contact area than the previous one.

3. Fine grinding

400 µ – Fine III Dry (no lumps)
it is fine, but not a powder, you can see little boulder parts. Used mainly for espresso and Moka Pot, but some Aeropress recipes use this grinding in a short time extraction. The substances extraction is high, it has high surface area contact, and it is used in methods with pressure, less time, high temperature.

4. Medium-fine grinding

500-600 µ – Medium – Fine (beach sand)
it is finer than sand, but not as fine than the previous. It is perfect for tuned recipes with pour-over methods, V60, Kalita, et cetera and also for some Aeropress recipes. It can be tricky if you do not master the brewing techniques leading to clogging. The substances extraction is high; it has a high surface contact area, but less than the previous one.

5-6.Medium grinding

700-800 µ – Medium I (Table Salt)
it is the start point for a test with a new coffee, it is a little bit coarse than the medium-fine. Very similar, in consistence and size, to sand. Can be used in various methods like pour-over, siphon, Aeropress, infusion, et cetera. The water-substances interaction is medium here, as the surface contact area is starting to decrease. In this grind size, and beyond, other variables like temperature and time become to influence more and more. It is the grind size that doesn’t extract too much but don’t extract too little.

7. Medium-coarse grinding

900-1000 µ – Medium II Commercial
it has the aspect of sand with boulder particles. Methods like Chemex, Clever and Aeropress benefit a lot from this grinding size, also some pour-overs with a little adjust in the variables. The surface contact area is smaller, so the solubility of the substance in water become to decrease. In this case, extraction is medium and extraction time starting to get more attention.

8. Coarse grinding:

1100-1200 µ – Medium III (Silica Sand)
it is more rough than sand, almost a sea salt, you can see boulder particles. Methods like French Press and some percolators are the best ones applied here. It is also very used to coffee cupping/tasting. In this case, extraction becomes small to medium, there is even less surface contact area with water and extraction time become fundamental.

9. Coarsted grinding

1300-1400 µ – Coarse I (clay particle)
similar to peppercorns. Used mainly for cold brew due to small substances extraction rate because the surface contact area is little, the pores are not available for extraction.

10. Extreme coarse grinding

1500-1600 µ – Coarse II (coarse kosher salt)

also similar to peppercorns, also used for cold brew. The substances are even less extracted than the previous. The surface contact area is small.
1600µ – Extra Coarse (III) – (broken peppercorns)
