How to Make Cold Brew in a French Press
Why a French Press Works So Well for Cold Brew
Most people think of a French press as a hot coffee tool, but the real fact is that its design is genuinely perfect for cold brewing. The mesh plunger acts as a built-in filter, so you don’t have to deal with the hassle of paper filters or any special equipment.
Soak the coffee grounds in cold water; once ready, press down the plunger and then pour it out. That’s it. As a result, you get a smooth, rich, and concentrated extract with low acidity that pairs perfectly with ice.
Cold brew is different from iced coffee in one important way, and that is it is never exposed to heat. When coffee is brewed hot and then cooled down, the flavor profile changes. Acids develop, bitterness can spike, and that sharp edge lingers. Cold brew skips all of that.
The slow extraction at a low temperature pulls the smooth, chocolatey, mellow notes from the beans while leaving behind most of the sharpness. This is a coffee that is really easy to make at home.
What You'll Need
We keep the list of ingredients for making cold brew in a French press very simple. You don’t need to buy anything new to get started; the list of necessary materials is very short. It couldn’t be simpler.
Ingredients:
- 1 cup coarsely ground coffee (around 100g)
- 4 cups cold filtered water (around 950ml)
- Ice for serving
Equipment:
- A 32oz or larger French press
- A fine mesh strainer or cheesecloth for a cleaner finish
- A clean glass jar or pitcher for storing the finished brew
How to Make Cold Brew in a French Press — Step by Step
Step 1: Add the coffee
Take out the plunger from your French press completely and set it aside. Measure out 1 cup of coarsely ground coffee and pour it directly into your French press. Now give it a gentle shake to settle the grounds evenly across the bottom.
Step 2: Pour in the water
Add 4 cups of cold filtered water slowly. You need to pour water in a circular motion so all the coffee grounds become evenly wet. After that, use a long spoon to give it one gentle stir. We need this to make sure no dry grounds are sitting on top.
Step 3: Place the lid on without plunging
Now, attach the lid with the plunger pulled all the way up. You do not need to press it down yet. The lid is just there to keep the carafe covered during the brewing process. Pressing at this stage would force the grounds down too early, which would disrupt the extraction.
Step 4: Refrigerate for 12 to 24 hours
Place the French press in the back of your fridge and leave the mixture untouched. After 12 hours, you will get a lighter, smoother result. 18 to 20 hours is the sweet spot most people settle on.
On the other hand, steeping for 24 hours produces a bolder, stronger concentrate. We suggest you start at 18 hours and adjust from there based on your taste.
Step 5: Press slowly and pour
When the steep time is up, you can press the plunger down very slowly and steadily. If you feel resistance, ease up slightly rather than forcing it. A rushed press pushes fine sediment through the mesh and makes your cold brew gritty. Once fully pressed, pour immediately into a clean jar.
How to Serve It
What you have prepared is a concentrated extract, and it is much stronger than what you usually drink. So, the question is how you can use it to make a perfect cup of coffee. Here we share four different methods for making your morning coffee using it.
- Standard cold brew: Mix one part concentrate with one part water over ice. Adjust the quantity to taste.
- Cold brew latte: Use oat milk, almond milk, or whole milk instead of water. There is no need to add any extra sweetener; it is naturally smooth on its own.
- Hot cold brew: Yes, this is no joke; it is truly possible. Pour hot water over your coffee concentrate instead of cold water. This produces a hot coffee that tastes wonderfully smooth and has low acidity.
- Sweetened version: If you prefer a slightly sweet taste, it tastes great with a little ‘simple syrup’ (concentrated sugar solution), vanilla, or honey mixed in.
A Few Tips Worth Knowing
Here we share some tips that will help you make a perfect cold brew to enjoy every morning. You can give them a try, and we hope that your cold brew experience will improve.
- Try to use filtered water if possible. If tap water has a strong taste or odor, it can transfer to your cold brew; filtered water, on the other hand, preserves the purity of the drink’s flavor.
- Do not cut the steeping time short. If it isn’t steeped long enough, cold brew tastes bland and watery. So, the wait will be worth it.
- Bitterness is a sign that something has gone wrong. Generally, this means the coffee grounds were too fine, steeped for too long, or pressed during filtration. Therefore, you need to make a change to one of them; only then will your next batch be significantly better.
FAQs
Can I use regular ground coffee for cold brew?
Obviously, you can do that, but grind size matters. Regular pre-ground coffee is usually a medium grind, which can cause over-extraction and leave your cold brew bitter or murky. A coarse grind works best. If medium-ground is all you have, shorten the steep time to 10–12 hours and strain through a cheesecloth to catch the fine particles.
How long does cold brew last in the fridge?
Generally, cold brew concentrate stays good for up to two weeks in a sealed glass jar. That said, it tastes best during the first week. However, if you have already diluted it with water or milk, try to finish it within 3–5 days.
What’s the best coffee bean for cold brew?
Undoubtedly, medium-to-dark roasted coffee beans are the best choice. They bring out chocolate, caramel, and nutty notes that cold extraction handles really well. If you prefer something with fruity or floral notes, light roasts would also be a good choice. Whatever you choose, freshness is the most important factor; so, use beans that have been roasted within the last few weeks.
Final Thoughts
Making cold brew coffee at home is one of those things that sounds more complicated than it actually is. The truth is, once you try it, you will realize the hardest part is simply waiting for it to finish steeping overnight.
The French press makes the entire process much easier. No special equipment, no complicated setup, just coffee, cold water, and a little patience. In return, you get a smooth, rich-tasting beverage with low acidity; it stays fresh in the refrigerator for up to two weeks and tastes far better than most high-priced café drinks.
So, the next time you go to order cold brew, you might consider making a large batch of it at home instead. It takes only ten minutes of sincere effort, and the results are proof of that.
