Cold brew coffee is known for its smooth, rich flavor and low acidity, making it a popular choice for coffee lovers, especially during the warm months. If you’re looking to make cold brew coffee at home, the Chemex is one of the best tools to achieve a clean and crisp brew. With its elegant design and high-quality materials, the Chemex coffee maker produces an exceptional cold brew that highlights the unique flavors of your coffee beans.
In this guide, we’ll walk you through the step-by-step process of making cold brew in a Chemex, from choosing the right ingredients to storing your cold brew for the freshest taste.
What Is Cold Brew in a Chemex?
The Chemex coffee maker is an iconic and beautifully designed brewing tool known for its smooth and balanced coffee. When it comes to cold brew, the Chemex is an excellent choice for several reasons. Its thick paper filters are ideal for filtering out the oils and fine particles that can make cold brew taste gritty or overly bitter. The result is a crisp, clean cup of coffee, perfect for those who enjoy cold brew’s smooth, mellow taste without the added sediment.
Additionally, the Chemex’s elegant design and sturdy glass body make it an attractive addition to your kitchen, allowing you to serve cold brew directly from the brewer. Whether you’re brewing for yourself or entertaining guests, the Chemex adds an extra touch of class to your cold brew experience.
Ingredients and Equipment
Before you start, gather the following ingredients and equipment:
Ingredients
Coarsely ground coffee: For best results, use high-quality, freshly ground coffee. The coarser the grind, the better the extraction.
Water: Fresh, filtered water is essential to making great cold brew coffee. Avoid using tap water that may have off-flavors.
Equipment
Chemex coffee maker: The size of your Chemex will determine how much coffee you make, but a 6-cup Chemex is a common choice for cold brew.
Chemex filters: These special filters are thicker than standard paper filters, which helps create a clean, sediment-free brew.
A scale: A digital scale will help you measure the precise amount of coffee and water for the perfect ratio.
A timer: While you don’t need to time every step of the process, a timer will help you monitor the steeping time.
A spoon or stirring stick: To mix the grounds and water evenly.
A large jar or pitcher (optional): If you prefer to transfer your coffee to a separate container for steeping.
Step-by-Step Instructions
Making cold brew in a Chemex involves just a few simple steps. Here’s a guide to help you brew your own batch of cold brew coffee.
1. Measure the Coffee and Water
The key to great cold brew is the right coffee-to-water ratio. For a strong concentrate, use a 1:5 or 1:6 ratio of coffee to water. For example:
1:5 ratio: Use 1 cup of coarsely ground coffee to 5 cups of water.
1:6 ratio: Use 1 cup of coarsely ground coffee to 6 cups of water.
You can adjust the ratio depending on how strong you like your cold brew. If you want a more intense flavor, go for the 1:5 ratio. If you prefer a lighter brew, the 1:6 ratio is a good choice.
2. Add Coffee Grounds to the Filter
Place a Chemex paper filter in the top of your Chemex coffee maker. Make sure the thicker side of the filter is facing the spout to avoid any overflow. This side should also be folded along the edges, creating a sturdy filter structure.
Once the filter is in place, add your measured amount of coarsely ground coffee to the filter. Gently shake the Chemex to level out the grounds for an even extraction.
3. Pour Water Over the Grounds
Now, it’s time to pour the water over the coffee grounds. The process of pouring water is crucial for ensuring an even extraction. Start by pouring just a small amount of water—about twice the weight of the coffee grounds—to saturate the grounds evenly. Allow the coffee to bloom for about 30 seconds. The blooming process releases carbon dioxide, which enhances the extraction of flavors.
After the bloom, slowly and steadily pour the remaining water over the coffee in a circular motion. Ensure that the water fully saturates the coffee grounds. The entire process should take about 3-5 minutes, depending on the amount of coffee you’re making.
4. Steep the Coffee
Once you’ve added all the water, cover the Chemex with a lid or a clean towel. Let the coffee steep for 12-24 hours at room temperature or in the refrigerator. The steeping time depends on your preference for strength. A 12-hour steep will yield a lighter concentrate, while a 24-hour steep will give you a stronger, more intense brew.
While it’s not necessary to stir the coffee during steeping, you can give it a gentle swirl after a few hours if you notice uneven extraction.
5. Filter the Cold Brew
Once your coffee has steeped for the desired amount of time, it’s time to filter it. Chemex filters are designed to trap fine coffee grounds, which results in a smooth and clean cup of cold brew.
Carefully pour the steeped coffee through the Chemex filter to separate the liquid from the grounds. The filter will capture most of the coffee grounds, leaving you with a smooth and sediment-free concentrate.
If you used a large Chemex to brew your cold brew, it might be useful to transfer the concentrate to another container, such as a jar or pitcher, for easier storage.
6. Store the Cold Brew
Once your cold brew is filtered, transfer it to an airtight container and store it in the refrigerator. Cold brew can be stored for up to a week, but it’s best enjoyed within the first few days for the freshest taste.
Cold Brew Concentrate vs. Ready-to-Drink
Cold brew made in a Chemex is typically a concentrate, which means it’s stronger and can be diluted with water, milk, or a milk alternative to suit your taste. This concentrate can be served over ice or mixed with sweeteners or flavorings.
If you prefer a ready-to-drink cold brew, simply adjust the coffee-to-water ratio before steeping. You can use less coffee or add more water to make the brew less concentrated. However, many cold brew enthusiasts prefer the flexibility of making a concentrate since it allows for easy customization.
Flavor Customization Options
Cold brew is a versatile coffee drink, and there are many ways to enhance its flavor. Some ideas for customization include:
Vanilla syrup: Add a splash of vanilla syrup for a sweet, aromatic twist.
Cinnamon: A sprinkle of cinnamon in the brewing process or on top of the finished drink adds a warm, spicy flavor.
Chocolate syrup: For a rich, indulgent cold brew, add a bit of chocolate syrup.
Milk or milk alternatives: Try adding oat milk, almond milk, or regular milk to your cold brew for a creamy texture.
Sweeteners: If you prefer sweet cold brew, experiment with sugar, agave syrup, or simple syrup.
You can also experiment with flavored syrups, spices, or even a splash of flavored liqueur for an adult beverage.
Storage Tips
To ensure your cold brew stays fresh, store it in an airtight container in the refrigerator. Since cold brew is a concentrate, it can last for up to a week, but the fresher, the better.
Avoid storing cold brew in direct sunlight or in containers that aren’t sealed properly, as this can lead to the coffee losing its flavor or becoming stale. You can also divide the batch into smaller containers to keep it fresh for a longer period.
Common Mistakes to Avoid
While making cold brew in a Chemex is simple, there are a few common mistakes to watch out for:
Using a too-fine grind: A fine grind can cause over-extraction and a bitter taste. For the best cold brew, always use coarsely ground coffee.
Incorrect coffee-to-water ratio: Make sure to measure your coffee and water correctly. Too little coffee can result in a weak brew, while too much can make the cold brew too strong or overly bitter.
Insufficient steeping time: Don’t rush the steeping process. Cold brew requires a long steeping time to develop its full flavor, so be sure to let it steep for at least 12 hours.
Not filtering properly: Using the Chemex filter properly ensures a clean and smooth cup of cold brew. Be patient and pour slowly to ensure the coffee is filtered thoroughly.
Conclusion
Making cold brew in a Chemex is a simple, yet rewarding process that yields smooth, flavorful coffee. With the right ingredients, equipment, and a little patience, you can create cold brew that’s perfect for enjoying on its own or customizing with flavors. Whether you prefer a strong concentrate or a lighter brew, the Chemex allows you to control every step of the process to suit your taste. Enjoy your cold brew chilled, and experiment with different additions to make it your own signature drink.
By following these steps, you’ll have a high-quality cold brew that’s perfect for any coffee enthusiast.
