Preparation

1

Bring water to a boil
Let the kettle sit for about 30s for the water to settle

2

Place the filter inside the brewer
Open the Chemex filter so that there are 3 layers on one side and 1 layer on the other. Line up the side with 3 layers with the spout of the Chemex.

3

Rinse the filter with hot water
This will "prime" it, and help it adhere to the glass. Make sure to pour out rinse water before continuing.

4

Weigh and grind 50g of coffee
Grind to a medium-coarse setting. All grinders are different, but generally you want to set the grinder to 3/4 of the way to the coarse end (bigger numbers are coarser).

5

Pour ground coffee into the rinsed filter
Make sure the coffee bed is flat to ensure an even extraction

6

Place the Chemex on your scale and press tare to set the weight to zero

7

Begin your timer

8

0:00 - Pour 90 grams of water onto to the coffee
Wait 30s while the coffee degases. This is called the bloom.

9

0:30 - Slowly add water to the centre of coffee in a circular motion until you have reached 250g
Allow to drain

10

1:30 - Slowly resume pouring until you've reached 450g
Allow to drain

11

2:30 - For the final pour, continue until you've reach 700g
Allow to drain completely

12

Total brew time should be no more than 4min
If by 4 minutes your coffee has not fully drained, remove the filter and place in the sink until it finishes draining and grind slightly coarser next time.

13

Swirl the coffee for about 10s
This will add oxygen to the brew and make it sweeter

14

Enjoy your coffee!
