To make coffee concentrate, you can use a method called cold brewing. Cold brewing extracts coffee flavors from the beans slowly and creates a concentrated coffee that you can dilute with water or milk to make your desired strength of coffee. Here's how you can make coffee concentrate using the cold brewing method:
- Coarsely ground coffee beans
- Filtered water
Measure the coffee: Start by measuring the desired amount of coarsely ground coffee. A good starting point is a ratio of 1 part coffee to 4 parts water, but you can adjust this ratio to your preference.
Combine coffee and water: In a large jar or container, combine the measured coffee and filtered water. Stir gently to ensure all the coffee grounds are saturated with water.
Steep the coffee: Cover the jar or container and let it sit at room temperature for a period of 12 to 24 hours. The longer you steep the coffee, the stronger the concentrate will be.
Strain the concentrate: After the steeping period, line a fine-mesh sieve or a coffee filter over another container or jar. Slowly pour the coffee mixture through the sieve, allowing the liquid to strain through while capturing the coffee grounds.
Repeat straining if necessary: If your concentrate still has some sediment or coffee particles, strain it once again through a clean coffee filter or a cheesecloth to achieve a clearer concentrate.
Store and serve: Transfer the strained coffee concentrate into a clean jar or bottle with an airtight lid. Store it in the refrigerator, where it can last for up to two weeks. When you're ready to enjoy a cup of coffee, dilute the concentrate with water or milk to your desired strength. Start with equal parts concentrate and water/milk, then adjust to taste.
Remember, coffee concentrate is highly concentrated, so it's essential to dilute it before consuming. You can experiment with different ratios of coffee concentrate to water/milk to find the perfect balance for your taste preferences.
