Quality cold brewed coffee comes easy with the Ice coffee maker. Packed with two lids, the first one is to leave in the fridge overnight, and the one with a plunger to press down the coffee grounds in the morning. The 51 oz Cold Brew Ice Coffee Maker is made from plastic, silicone, and stainless steel and functions the same as a regular French press. Instead of hot water, add filtered water at room temperature and stir. Place the lid on the carafe and let brew for 12 - 24 hours at room temperature or in your refrigerator. Press and enjoy!
