How Do You Brew Cold Coffee With A French Press?

First, let us be clear about one thing. You do not make cold/iced coffee by plunging a few ice cubes into a hot cup of coffee. No. the ice will dilute that coffee, and you will never achieve that chilly nirvana.

To make the best iced coffee, simply change the coffee brewing process. As opposed to using hot coffee fresh from the French press, make a cold-brewed coffee chilled overnight in a French press. When you take it from the refrigerator, it will be super-cold and strong and ready to be consumed. You can dilute it by adding a little ice and milk.

When Do You Begin Preparing Your Cold Coffee?

A French press cold brew uses cold water at room temperature. As you may imagine, this will take more time since the coffee grounds will take time to steep. Lit would be best if you let it stay overnight.

Thus, it is ideal to start your process the night before. The extra time and cold brew process yield a more delicate flavor with a less bitter finish. This is how most coffee shops make extra-smooth and extra-strong cold-steeped that beats even the normal hot coffee.

Iced coffee in a French press surely piqued your interest

Here is how to make your cold coffee to serve one person.


  • 1 ½ cups of cold water
  • Milk
  • 1/3 cup of whole coffee beans
  • Ice
  • Sweeteners such as caramel, flavored syrups, or even melted chocolates

Equipment Needed


  1. Thoroughly grind the coffee beans until they attain a texture that can be filtered by your French press, but fine enough to permeate well. The texture should be something in between coarse and fine.
  2. Put the ground coffee and your 1 ½ cups water in the French press.
  3. Stir the water with the coffee gently until it incorporates and blends well.
  4. Secure the French press with a lid and ensure the plunger is in the up position.
  5. Put your French press with its contents in the fridge overnight. The plunger in the up position will ensure that the coffee grounds infuse with the water properly.
  6. The next day, remove your French press from the fridge and plunge it to separate the grounds from the coffee.
  7. Now you are ready to have your iced coffee. Add some ice cubes in a glass, fill partway with milk, and add your iced coffee. Stir to combine it, and Voila! Enjoy your cold coffee. You can also serve your cold-brewed coffee hot. Simply add one part of coffee and one part of water to a coffee mug. Put it in the microwave for 1 or two minutes and serve it.

Note: if you have a larger French press, you could make a larger batch of cold coffee. Just use the same ratio of water to ground coffee. Plunge and put the unused coffee in a separate container.

You can then store it in the fridge for up to one week. Now for those with a sweet tooth, you can consider stirring in some chocolate fudge or cajeta caramel. Cinnamon or sea salt can also do.

Mistakes To Avoid When Making Homemade Cold Iced Coffee

You want to make the perfect cold brew coffee. Avoid the following mistakes.

  1. Do not grind the coffee too fine. A fine grind will yield a bitter brew. Grind it to the texture of coarse sugar would be fine.
  2. Since a cold brew takes a longer time to make, it could be a waste of time making a brew for just two cups. Really after a whole night? Depend on the size of your French press, you can make as much to last you a few days or even a week.
  3. Cold-brew can last in the fridge for up to two weeks. Thus, if you are going to wait for the over 12 hours of prep, you can as well make as much as not to have to prepare more for days to come.
  4. Always soak your grinds for long enough to extract the tasty goodness. 12 hours in the fridge is not enough as it will produce a weak and astringent cold brew. 18-24 hours would be fine.
  5. Do not strain too quickly. I know you have waited overnight and you want quickly squeeze the brew through the strainer. You will end up with something bitter. For a big batch, strain in two batches and let the entire process take up to 30 minutes. Let it come out naturally and you will have a sweet and smooth cold coffee.
  6. Much as you can just take your cold brew neat straight from the fridge, you would only be revved up on high-octane coffee, missing the delight that comes with a sweetened ice-cold brew. For a balanced cup, you could add a little ice and water. Use a one-to-one ratio of your cold brew to filtered water and add ice over it.

How Do You Brew A French Press Hot Coffee?

Above, we have seen that you can put your French press in the fridge when preparing cold-brew iced coffee. However, ideally, the reason for purchasing the French press is so that you can make hot coffee at home. Here, you are going to learn how to make perfect French press coffee.

Of course, the French press process is going to be among the easiest and least expensive ways of making great coffee. The instructions below make 32 ounces, which is the common size for the French press. It will make about four servings. However, if you would like to make fewer or more servings you could use the following proportionality:

  • 1 cup water, 2 tablespoons coffee beans= 8 ounces fluid for one serving
  • 2 cups water, ¼ cup coffee beans= 16 fluid ounces for two servings
  • 4 cups water, ½ cup coffee beans=32 fluid ounces for four servings
  • 8 cups water, 1 cup coffee beans-64 fluid ounces for eight servings.

Note that you should measure the coffee beans before grinding.

Ingredients Needed

  • A ½ cup of freshly roasted coffee beans
  • 4 cups of cold water



  • Measure the coffee beans to the proportion you are making, in our case ½ a cup.
  • Grind the beans using the coarsest setting in your burr grinder. In the absence of a burr grinder, you could just grind them briefly with a blade grinder. The grounds should rough and course, but ensure the size is evenly distributed. Pour your grounds in the French press.
  • In an electric kettle or stovetop, boil the water and then let it rest for one minute. The water should be heated up to 195 degrees F, which is slightly below the normal boiling point of 212 degrees F. you can use a thermometer to double-check, though some kettles have custom temperature settings labeled as ‘coffee’.
  • Transfer your hot water into the French press and stir vigorously in an up and down motion.
  • To produce a robust brew, let it steep for 4 minutes.
  • Immediately the timer goes off, press the plunger to the bottom and serve your coffee. If you are not going to take the coffee immediately, do not leave it in the French press because it gets bitter as it sits on the grounds. Put it in a thermal carafe to keep it warm.

For simplicity, we skipped the process of warming the French press. If you have time, heat the water to the boiling point and rinse your French press with it in a bid to warm it.

  • Use coarse grinds to get the optimum flavor and avoid grit in the cup.
  • Remember balance is important for French press coffee. Use one cup of water for one tablespoon of coffee grounds for one serving.
  • Ensure to keep your French grit clean to avoid having ground residue next time you want to brew your coffee.
  • It is recommendable to start with fresh whole been as opposed to buying pre-ground coffee at the store.
  • Grind your coffee just right before brewing to maximize your brew’s boldness. 30 minutes prior is fine.
  • The best water to use is filtered water. Hard water leaves deposits in your coffee maker. Distilled water, on the other hand, over-extracts your coffee.
