<human>:  How do I make a cold brew coffee?
<bot>: To make a cold brew coffee, you need to start with coarsely ground coffee beans. Place the grounds in a container with cold water, making sure the level of the water is much higher than the grounds. Stir the mixture and let it sit in the refrigerator for at least 12 hours or up to two days. After the coffee has steeped, strain it with a fine-mesh sieve or cheesecloth. You can enjoy it straight or add milk or sweetener like sugar or honey.
