HARIO Filter-in Coffee Bottle 900ml Chocolat Brown Purchased new and used only once. In excellent condition. Thank you. A wine bottle-shaped cold brew coffee bottle. You can extract iced coffee using only coffee grounds and water. Put the coffee grounds in the strainer, close the lid, and set it on the spout, then pour water little by little. After pouring the water, close the stopper and gently shake the bottle from side to side to encourage extraction. Extract in the refrigerator for about 8 hours, and it's ready.
