Number 4-size Coffee Filter Cone, designed for 8 to 12-cup capacity, is ideal for manual pour-over coffee brewing. Enjoy fresh, single-cup coffee with each brew—no more stale or burnt coffee. Brew only what you need to reduce waste. Color: Black Size: 4 x 4 x 3.1 inches Material: Plastic This pour-over method, known as hand pour or hand drip, is a time-tested Japanese brewing technique developed to produce great-tasting coffee with full control over quality and flavor. Brewing is done by pouring a thin, slow, and steady stream of water over ground coffee. To use, place the Coffee Filter Cone over a mug or carafe. Insert a paper or reusable filter and add medium-grind coffee (approximately 2 rounded tablespoons per 8 ounces of water, or to taste). Use just-boiled water to wet the grounds evenly and let them bloom for 15 to 30 seconds. This allows the coffee to expand and release more flavor. Slow and precise water flow is essential for optimal flavor extraction. Pour the remaining hot water slowly and evenly in a circular motion, starting from the center and moving outward. Allow the coffee to fully drip through. Brew time should be approximately 2 minutes. Remove the cone, discard the used grounds, and enjoy your fresh coffee immediately or chill for cold coffee drinks. This non-breakable, reusable coffee filter cone is a perfect portable option for coffee lovers on the go. It is easy to use, easy to clean, and dishwasher safe.
