Place a small cup on the digital kitchen scale and press Tare to make it 0. Add 40 grams of coarsely ground coffee beans to the cup.
Place a naturalfilter into the Chemex. Boil a small amount of water, and pre-wet the filter, swirling the hot water inside of the bottle to pre-heat the glass. Pour out the water and add the measured coffee beans to the filter.
Bring 600 grams (20 oz) of water to a boil.
Pour the boiling water into the pour over kettle.
Place the Chemex on the digital scale and press Tare to 0 the weight. Pouring slowly over the coffee beans, start on the outer rim of the filter and move in, adding 60 - 100 grams of boiling water, completely saturating the beans. Watch the beans "bloom" as it rises, releasing Co2. It will bubble and soften, allow it to breathe. This will be the most bitter part of the brew, so be careful to only add a small amount of water to the first pour.
Wait 30 seconds and add another 150 grams of water, starting from the center of the filter and pouring towards the rim, then back to center. This allows the beans to become completely saturated and evened out.
After about a minute, add another 200 grams of water.
Wait for the water to filter the coffee, then add the remaining 150 grams of water.
Note: Use a 1 to 15 coffee bean to water ratio.
For a single serve, one cup brew, use 23 grams of coffee beans and 350 grams of water.
Enjoy the perfect cup! If you have any tips for the perfect cup, please share!
