A general guideline is to use a 1:8 coffee-to-water ratio for a strong cold brew or a 1:10 ratio for a milder brew. However, feel free to adjust these ratios according to your taste.

• A 1:8 ratio means using 1 part coffee to 8 parts water. For example, if you're using 4 ounces of coffee grounds, you would use 32 ounces (or 4 cups) of water.
• A 1:10 ratio means using 1 part coffee to 10 parts water. Following the same example, you would use 40 ounces (or 5 cups) of water.

3. Understand the flavor profile: The coffee-to-water ratio directly influences the flavor of your cold brew. A higher coffee-to-water ratio will result in a stronger, more concentrated brew with a bolder taste. On the other hand, a lower ratio will yield a milder, less intense flavor profile.

• A 1:8 ratio creates a strong and robust cold brew with pronounced flavors and a higher caffeine content.
• A 1:10 ratio produces a smoother and more balanced cold brew, ideal for those who prefer a milder taste or want to enjoy their cold brew over a longer duration.

4. Customize to your taste: The beauty of cold brew is the ability to tailor it to suit your individual preferences. If you find a 1:8 ratio too strong, you can decrease the coffee grounds or increase the water to achieve a milder brew. Conversely, if a 1:10 ratio is too weak for your liking, you can adjust by adding more coffee or reducing the water amount.

• Remember that experimenting with different ratios is the best way to find your ideal coffee-to-water ratio for the Chemex cold brew method.

In conclusion, the coffee-to-water ratio is a critical factor in determining the strength and flavor of your cold brew using the Chemex Pour-Over Glass Coffeemaker.
