Cold brew is a smooth, sippable form of cold coffee that is beloved in cafes around the globe, but how do you bring that irresistible flavor home? Explore your deliciously chill options with this helpful guide to making cold brew in a French press!

If you love fresh, cold brewed coffee, you have probably wondered how to make it. This silky smooth yet boldly robust cold coffee is a cafe favorite, but it’s easier to make at home than one might believe! All you need is a slightly surprising tool: the French press. With this handy coffee brewer, the perfect cold coffee is easier to make than ever before!

What is Cold Brew?

Cold brew is exactly what the name implies. It is coffee that is brewed using cold water instead of warm. Cold water extraction takes longer than hot water coffee extraction, so cold brew is a slow brewing method with a smooth and delectable palatable result.

Cold brew is extracted with cool, filtered water over a period of six to twelve hours. To get the most delicious flavor from this brewing method, the coffee is ground into coarse chunks. When the process is done, the grounds are strained, and you are left with a low-acid, complex, and velvety cup of cold coffee.

This brew may look a lot like iced coffee, but it’s very different. Iced coffee is brewed hot and then chilled; that process can give the coffee a slightly sour or bitter twinge. A cold brew starts and stays cool, which produces a mildly sweet, low-acid, smooth cup of coffee.

Why Use a French Press for Cold Brew?

Cold brew is made with chunky coffee grounds that need to get strained out of the finished brew. That is what makes the French press such a perfect tool for brewing cold coffee!

The design of this classic brewer is perfect for steep-style brewing methods, like cold brew. Plus, the built-in strainer makes removing the coarse grounds easy and mess-free!

French presses also come in a wide range of sizes. This means you can make exactly the right amount of coffee for your household size every time!

Coffee Ratio for Cold Brew in a French Press

There isn’t a fixed ratio for cold brew, but a typical recommendation falls between 1 to 6 and 1 to 10. In practical terms, this translates to around 60-100 grams of coffee per liter of water (or approximately 2.12-3.53 ounces per quart).

Looking at cold brew as a ratio allows you to make as much or as little coffee as you need. You can brew a batch of cold brew and store it for use over the next few days.

For your convenience and to deliver a milder, more delicate cold brew using the French press, I’ve outlined the ratio of 1 to 6 in the table below. Typically, my go-to ratio for cold brew is 1 to 8 unless I’m preparing beverages like cocktails or shakes that demand a robust, intense flavor. I opt for a higher ratio in those cases, leaning towards 1 to 10 on the scale.

How to Make Cold Brew Coffee in a French Press

Follow this easy guide to perfectly balance and delicious cold brew in the French press every time!

What You Need

Cold brew only requires two ingredients: filtered water and coffee. Use the ratios above to determine how much of each ingredient you need for your batch.

Filtered water makes for the most natural and pure taste in the finished coffee, but you don’t need a fancy filter. Use a filtering pitcher, built-in sink filter, or bottled filtered water for flavor.

The size of the coffee grounds is essential to this recipe. For the best brew, use coarse-grind coffee beans. The grind size should be about the size of chunky ground peppercorns.
