Use the scale to weigh 50 g of coffee and 350 g of water. This is a cold brew concentrate recipe, so use a higher coffee to water ratio than you normally would.

Cold brew requires coarse ground coffee. If you’re familiar with French press grind size, use a slightly larger grind for cold brew.

Add the ground coffee and water to your brewing vessel. Stir the mixture to ensure all the grounds are wet.

Let the cold brew steep for 16 hours at room temperature.

If you’re using a French press, you can use the plunger to separate the grounds from the cold brew. If you’re using another type of container, you can use an ordinary kitchen strainer.

Even though you’ve already separated the grounds from the coffee, fine sediment might be left suspended in the coffee. Slowly pour the cold brew through a paper filter to remove any small particles left behind by the strainer. This step is essential if you want to keep your cold brew in the fridge for several days.

If you’re not going to drink all of the cold brew at once, make sure you keep it in the refrigerator. Cold brew concentrate stays good for up to two weeks when you keep it refrigerated.
