To make cold brew in a French press, combine coarsely ground coffee with water at a 1:8 ratio, let it steep in the refrigerator for 12-24 hours, then gently press and filter for serving. This method provides a smooth, rich coffee concentrate that can be diluted and stored for up to two weeks.
Weigh Coffee and WaterCold brew coffee is generally brewed using a 1:8 coffee-water ratio. This means that for every 1 unit of coffee, you’ll use 8 units of water. For example, for a 400 ml brew, you can use 50 grams of coffee.
Grind Coffee BeansWeigh and grind your coffee beans according to the amount of cold brew you want to make. I recommend using a burr grinder to achieve a more consistent grind.
Add Coffee and WaterAdd the appropriate coffee and cold water to your French press, following the coffee-water ratio. For cold brew coffee, the water temperature should be at room temperature.
Stir and Let Your Coffee SteepAfter adding the water, mix with a spoon until you are sure all the coffee grounds are wet. Then leave it to brew.Cold brew coffees are generally left to brew between 12-24 hours. As the brewing time increases, you will get stronger coffee. You can find the most suitable one by experimenting with this brewing time. A 16-hour brew would be ideal for a start.
Press the PlungerPress down on the plunger after allowing the coffee to steep for the necessary brewing time. Only lower it until it reaches the surface of the coffee. Pushing it all the way down will agitate the coffee grounds and result in undesirable sediment in your cup.
ServeIf you have made a coffee concentrate, use a 1:1 ratio as the coffee concentrate-water ratio. Add 1 part water to 1 part coffee concentrate and serve. This is the traditional ratio used for cold brew coffee concentrate.
Notes
Quality Water: Use clean, cold water. It's the canvas for your brew, so make sure it's fresh and free of impurities.Experiment with Time: Try different steeping times to find your perfect balance. Some prefer a longer steep for a stronger flavor, while others may opt for a shorter duration.Filtering: After steeping, press down the plunger slowly and steadily. For a cleaner brew, consider filtering the cold brew through a paper filter or a fine-mesh sieve.Serve Over Ice: Cold brew is traditionally served over ice. This not only chills the brew but also dilutes it slightly, enhancing the flavors.Experiment with Add-ins: Customize your cold brew with add-ins like milk, cream, sweeteners, or flavored syrups. This allows you to create your own signature cold brew experience.
