Combine & Saturate: In your large pitcher or jar, combine the 1 cup of coarse coffee grounds and 4 cups of filtered water. Stir gently to ensure all the grounds are thoroughly wet.

Steep Patiently: Cover the container and let it steep for 12 to 18 hours. You can leave it on the counter at a cool room temperature or place it in the refrigerator.

First Strain (The Big Stuff): Slowly pour the steeped mixture through a fine-mesh sieve into a large bowl or another pitcher. This will remove the bulk of the coffee grounds.

Second Strain (The Secret to Clarity): Line the sieve with a paper coffee filter and place it over your final storage container. Slowly pour the coffee through this second filter. This crucial step removes the fine sediment (silt) and guarantees a crystal-clear, grit-free concentrate.

Store: You now have a beautiful cold brew concentrate! Store it in a sealed, airtight container in the refrigerator. For the best flavor, enjoy it within one week, but it will last for up to two weeks.

Serve: To serve, fill a glass with ice. Pour in the concentrate and dilute it with a 1:1 ratio of water, milk, or creamer. Taste and adjust the ratio until you find your perfect strength.
