Take the Plunge: French Press Cold Brew

Do you really need a specialized brewer like the Hario Mizudashi to make great cold brew coffee?

Probably not. Your trusty French Press is more than capable of making a great cup.

In this recipe, you'll learn how you can make delicious, easy-to-brew, and refreshing cold brew using just your French Press coffee maker.

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. In our recipe, we use a 1:8 coffee to water ratio.


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!


Sidebar: More help with ratios and dilution

  • Helpfully, one milliliter is equal in mass to one gram, when weighing your water.
  • To vary the size of your brew:
    • Using our ratio (1:8): you’ll need 12.5 grams of coffee for every 100 mills (grams) of water.
      • Just remember, this ratio produces a concentrate, which should be refrigerated after brewing, and cut with water or ice before serving. This will let you maximize your time and effort, whether you’re brewing with a small, single serving French press, or brewing a week’s worth of concentrate in a 1,700 mill beast.
  • To brew a mellow, ready-to-serve cold brew: For a larger press (because you’re not worried about maximizing servings through a concentrated brew), we recommend a ratio of 1:12, or 8.4 grams of coffee for every 100 mills (grams) of water you’re adding.
    • Repeat the outlined directions with this ratio, ignoring our advice to dilute the brew afterwards, and you’re ready to sip!
