Previously, we tested, tweaked, and toiled over a few specialized cold brew makers in our blog, “Cold Brew Off: Hario vs. Kinto vs. Toddy”. We had a lot of fun working with the brewers and ultimately landed on the Hario Mizudashi as the winner, with the all around best features, ease of use, and brew quality.
Take the Plunge: French Press Cold Brew
But what if you don’t have one of these brewers? Or better yet, do you really need one of these brewers to make great cold brew coffee?
What if you only have a trusty French Press?
We’re here to help. Read on to see how you can make delicious, easy-to-brew, and refreshing cold brew using just your French Press coffee maker.
BEFORE WE BEGIN: DOSING AND DILUTION
We covered terms like "ratio", "concentrate", and "dilution" in our blog, “Cold Brew: 5 Things You Should Know”. Long story short, most cold brew is not made ready to drink - or if you do drink it, you will be drinking a very caffeinated, very strong cup of coffee. Instead, you’re using a smaller portion of water to do the brewing, and then “cutting” the concentrate when you’re ready to drink it.
French Presses also come in a wide variety of volume options. We’ve seen some as small as 400ml, and then others that are gargantuan whoppers, weighing in at 1.5 to 2 liters! Our current pick for a French Press, the Yama 6 Cup, is a little over 800ml. With that kind of diversity, it can be hard to know where to start.

Our baseline for Cold Brew in a French Press
This recipe covers how to get the most cups out of a smaller (1 liter and under) French Press by using a tight ratio, which can also be used to produce a week’s worth of concentrate in a larger press. You can also see how to brew a smooth, easy extraction in a larger French Press in our sidebar below.
Overall, however, cold brew is a forgiving process and you should feel confident that you’ll get something great. We used our Haya Cold Brew Blend because we know it’s been roasted and blended to create a classic cold brew, but experimenting with single origins is always recommended!
Note: Cold brewing takes a while. Our recipe requires 16-20 hours of ambient temperature brewing. Be sure to start your brew with a plan, so you don’t miss the window for finishing up the next day!

Cook / Brew Time
The French Press is a remarkable cold coffee brewer. The extra body it yields pairs wonderfully with the rich chocolates and caramels that cold brew coffee is known for.
This recipe covers how to get the most cups out of a smaller (1 liter and under) French Press by using a tight ratio, which can also be used to produce a week’s worth of concentrate in a larger press.
WHY BREW IT THIS WAY:
- You’ll be able to get more cups out of this method, eliminating the need to brew daily.
- Allows you to pour equal amounts water or ice to “cut” the concentrate before drinking. Example: You pour 100ml of concentrate with 100ml water & ice to get to the strength of a regular cup of coffee.
75g coffee, ground coarse. If selecting a grind from our web store, choose "French Press"
600mL fresh, filtered water. Room temperature.
1 6-10 cup French Press Coffee Maker
Put coarsely ground coffee grounds into French Press
Tare your scale
Using ambient (room) temperature water, pour in enough water to cover the grounds and stop
Stir the grounds with a spoon, or simply swirl, to get everything evenly wet
Pour in remaining water up to 600ml
Cover brewer and put in a place away from sunlight
After 16-20 hours, remove cover and break any remaining “crust” from the brewer
Slowly, very slowly, plunge the filter down until it sits just above the rested coffee bed
Enjoy! We recommend diluting with an equal amount of water to get something close to the strength of normal drip coffee, but you can experiment and dilute to suit your tastes!
- Cold brewing takes a while. Our recipe requires 16-20 hours of ambient temperature brewing. Be sure to start your brew with a plan, so you don’t miss the window for finishing up the next day!
- You should expect around 450 mL of drinkable cold brew coffee concentrate.
- Diluting this with equal amounts of water gets you 2 or 3 full servings of cold brew coffee. Ice will get you a little further, as well.
- Results should be strong and rich, nicely chocolate-y but still with a mellow acidity; should be diluted at a 1:1 ratio for a smooth and drinkable cup, or over a full glass of ice with a dash of water. It’s always worth making a note and adjusting your cut for your own personal taste!
- For lighter single origin roasts, we recommend adding a few hours to this recipe (20+).
