Hello Madison2001. When preparing a cold brew concentrate for your meal prep, a standard and reliable ratio is 1:4 by weight, meaning one part coarse ground coffee to four parts cold filtered water. Alternatively, by volume, it is usually about 1 cup of coffee grounds to 4 cups of water.
To ensure your concentrate stays fresh for several days in the fridge, follow these steps:
1. Combine the coarse coffee grounds and cold water in a large jar or pitcher.
2. Stir gently to make sure all the grounds are fully saturated.
3. Cover and steep in the refrigerator or at room temperature for 12 to 24 hours.
4. Strain the mixture twice using a fine-mesh sieve lined with cheesecloth or a paper coffee filter to remove all sediment.
Store the strained concentrate in a sealed glass container in the refrigerator. It will easily keep for up to 7 to 10 days without losing its flavor profile, allowing you to dilute it with water or milk throughout the week.
