“Coffee brewed slowly in cold water is less acidic than hot brewed. You can use this concentrate straight over ice or microwave half a mug coffee and then add a half cup of boiling water for quick hot coffee. Develop your own ratio of coffee to water for your custom brew.”
- Put coffee grounds in a large container. Slowly pour water over the grounds.
- Cover bowl with plastic wrap and steep at room temperature for 18 to 24 hours.
- Line a strainer with several layers of cheesecloth and place atop a pitcher; strain coffee through the cheesecloth into the pitcher. Discard the grounds. To get a clearer brew, strain coffee again through coffee filters. Store in refrigerator.
