Enjoy a strong and cold cup of coffee with this Cold Brew Coffee Maker 1500ml Pot! Now cold-brewing coffee is an easier process! Unlike other coffee makers, this machine uses cold temperatures to brew coffee granules. It is suitable for medium to coarse-grind coffee beans. Simply add coffee and water in a 1 to 15 ratio. Then, leave it in the refrigerator for at least 8 hours. Just like that, you can enjoy authentic cold brew coffee already.
