Our cold brew maker is designed to provide a hassle-free experience while delivering deliciously smooth cold coffee. Simply measure 140 grams of coffee, grind until coarse, and pour it into the filter. You can use the fill line on the filter as a guide if you prefer. Then, place the filter into the pitcher, twist it into a locking position, and pour 1.5 quarts (48 oz) of room temperature water over the grounds, or use the vessel fill line if preferred. After lightly stirring for 20 seconds, let it brew for 18 hours in the refrigerator with the lid on. Once brewed, remove the filter, place the lid back on, and your cold brew is ready to enjoy! When inserting or removing the filter from the vessel, feel free to use the convenient filter handle which folds up or down for ease of use. The airtight lid design also ensures flavor preservation and freshness for an extended period, and comes with an easy-pour feature once your cold brew is ready to go. Plus, its convenient size fits in most refrigerator doors, and it's top-rack dishwasher safe for easy cleaning.
