Place the stopper on the outside bottom of the brewing container. Then, remove the filter and place it on the inside bottom of the brewing container. Next, add 200 ml of water to the bottom of the container and 170 grams of ground coffee. Slowly pour an additional 700 ml of water on top, in a circular motion. Then, add the remaining 170 grams of ground coffee. Finally, wait 5 minutes and slowly add the last 700 ml of water.
Press down with the back of a spoon to ensure the grounds are wet. Do not stir as stirring can lead to a clogged filter.
Leave your coffee for 12 to 18 hours to create a smooth, rich flavor.
