Cold brew coffee has become increasingly popular for its smooth, less acidic taste and the perfect pick-me-up for a hot summer day. If you’re looking to make cold brew coffee at home, using a French press is an easy and effective method. In this guide, we’ll walk you through every step of the process, from the ingredients to customization tips, ensuring you can make delicious cold brew coffee right in your own kitchen.
What Is Cold Brew Coffee?
Cold brew coffee is a method of brewing coffee where coarsely ground coffee beans are steeped in cold or room-temperature water for an extended period, usually 12-24 hours. This slow extraction process results in a rich, smooth, and less acidic coffee, making it a favorite for those who prefer a milder taste compared to traditional hot-brewed coffee. Cold brew also has a naturally sweeter flavor, without the bitterness that often comes with hot brewing methods.
Why Use a French Press?
A French press is one of the best tools for making cold brew coffee at home because it offers simplicity, versatility, and excellent control over the steeping process. Unlike other methods like a traditional drip coffee maker or immersion-style brew methods, the French press allows you to steep the coffee grounds directly in the water and then easily separate them when the brewing process is done.
Using a French press also gives you the flexibility to experiment with different brewing times and coffee-to-water ratios, allowing you to customize the strength and flavor of your cold brew to your liking. Its mesh filter ensures that no grounds end up in your cup, creating a clean and smooth cup of coffee.
Required Ingredients and Equipment
Before you begin making your cold brew French press coffee, let’s take a look at the essential ingredients and equipment you’ll need:
Ingredients
Coarsely Ground Coffee Beans: Freshly ground coffee is key to a great cold brew. You’ll need coffee that’s ground coarsely, similar to the texture of sea salt, to ensure proper extraction and prevent clogging the French press filter.
Filtered Water: Cold or room-temperature filtered water is best for cold brewing, as it helps produce a cleaner taste without any unwanted flavors.
Optional Ingredients
Milk or Milk Alternatives: If you like your cold brew with a creamy texture, you can add milk, oat milk, almond milk, or any other preferred milk alternative.
Sweeteners: You can sweeten your cold brew with sugar, honey, agave syrup, or even flavored syrups.
Ice: To serve your cold brew cold and refreshing, ice cubes or crushed ice are ideal.
Equipment
French Press: A standard 34 oz (1L) or 51 oz (1.5L) French press will work, depending on how much cold brew you want to make.
Coffee Grinder: A burr grinder is preferred for consistent, coarse coffee grounds.
Large Jar or Pitcher: To steep the coffee, a large jar or pitcher that fits the French press works best.
Spoon or Stirrer: You’ll need something to gently stir the coffee and water to ensure an even extraction.
Measuring Spoon or Scale: For accurately measuring the coffee grounds and water.
Step-by-Step Instructions
Now that you have everything you need, let’s go over the steps to make cold brew coffee in your French press.
1. Measure the Coffee
The first step in making cold brew is deciding on the coffee-to-water ratio. For a traditional cold brew, the recommended ratio is 1:8 coffee to water. This means for every 1 part of coffee, you’ll need 8 parts of water.
For example, if you are using 100 grams of coarsely ground coffee, you will use 800 grams (or 800 mL) of water. If you prefer a stronger cold brew, you can adjust the ratio to 1:7 or 1:6, but be mindful that it can become overly strong.
2. Add Coarsely Ground Coffee to the French Press
Next, place the coarsely ground coffee in your French press. Pour it into the bottom of the French press, making sure the grounds are evenly distributed.
3. Pour in Cold or Room-Temperature Water
Now, slowly pour your filtered water over the coffee grounds. Pour in a circular motion to ensure that all of the coffee is evenly wet and saturated with water. It’s important to use cold or room-temperature water instead of hot water, as hot water will create a very different flavor profile and is not suitable for cold brew.
4. Stir Gently
Using a spoon or stirrer, gently stir the coffee and water mixture for about 10-15 seconds. This helps to make sure that all the coffee grounds are thoroughly wet, which promotes even extraction during the steeping process.
5. Cover and Let It Steep
Once the coffee grounds are evenly saturated, place the lid on the French press, but do not press the plunger yet. Allow the coffee to steep at room temperature or in the refrigerator for anywhere between 12-24 hours.
The longer you steep, the stronger and more intense the flavor will be. If you prefer a lighter, milder cold brew, steep it for 12-16 hours. For a richer, more robust cold brew, steep it closer to 24 hours. Taste testing at different intervals is a great way to find the perfect brew time for your preference.
6. Press the Plunger
Once your coffee has steeped for the desired time, slowly press the plunger down with consistent pressure. Be gentle during this step to avoid forcing any grounds through the filter. This separates the coffee grounds from the brewed cold brew concentrate.
7. Pour the Coffee Into a Separate Container
After pressing the plunger, pour the cold brew into a separate container or pitcher for storage. This helps to avoid any additional coffee grounds from making their way into your final brew. You can transfer it into bottles for easier storage or into a large jug to serve.
Storage Tips
Store your cold brew in the refrigerator to keep it fresh. Cold brew coffee can stay fresh for up to 7-10 days, although it’s often best to enjoy it within the first week for optimal flavor.
Make sure to store your cold brew in an airtight container to prevent it from absorbing any odors from the fridge. You can also make a large batch to enjoy throughout the week.
Customization Ideas
One of the best things about cold brew is how easily you can customize it to your liking. Here are a few ideas for adding your own twist to your cold brew:
1. Add Ice
Since cold brew coffee is served chilled, adding ice to your glass is a great way to keep it cold. Just be aware that the ice will dilute the coffee as it melts, so you might want to brew it slightly stronger if you plan to add a lot of ice.
2. Milk or Milk Alternatives
If you prefer a creamy texture, you can add milk, cream, or a dairy-free alternative like oat milk or almond milk. Some people even enjoy adding a splash of sweetened condensed milk for a richer taste.
3. Sweeteners
Cold brew is naturally less bitter than hot coffee, but if you like it a bit sweeter, you can add sweeteners like simple syrup, honey, or agave. Try experimenting with flavored syrups, such as vanilla or caramel, for a fun twist.
4. Adjust the Coffee-to-Water Ratio
If you find that your cold brew is too strong or too weak, you can always tweak the ratio of coffee to water next time. For a bolder cup, try using more coffee grounds. For a lighter brew, reduce the amount of coffee used.
Troubleshooting
1. Over-Steeping
If you let your cold brew steep for too long, it may become overly bitter and harsh. If you accidentally steep it too long, you can dilute it with a little cold water or milk to balance the flavor.
2. Using Finely Ground Coffee
One of the biggest mistakes people make when brewing cold brew with a French press is using finely ground coffee. A finer grind can result in a cloudy, sludgy brew, and can clog the filter when pressing down. Always use coarsely ground coffee for cold brew to ensure a smooth, clean cup.
3. Not Stirring the Coffee Enough
If you don’t stir the coffee and water mixture enough after adding the water, some grounds may float on top, leading to uneven extraction. Make sure to stir gently to get a consistent brew.
Benefits of Using a French Press
The French press is an excellent choice for making cold brew coffee for several reasons:
Simplicity: It’s incredibly easy to use and doesn’t require special equipment or complex brewing techniques.
Control: The French press allows you to control the steeping time, which impacts the strength and flavor of your cold brew.
Quality: With its mesh filter, the French press ensures a clean, smooth cold brew without any floating grounds, delivering a great-tasting cup every time.
Versatility: Beyond cold brew, you can use the French press to brew hot coffee or tea, making it a multi-functional tool in your kitchen.
Conclusion
Making cold brew coffee with a French press is simple, rewarding, and customizable. By following the steps outlined in this guide, you’ll be able to create a rich and smooth cold brew that you can enjoy at home anytime. Whether you prefer it black, with milk, or sweetened with syrups, cold brew is a perfect way to enjoy coffee without the acidity and bitterness of traditional hot brewing methods.
