The most time-tested of Japanese coffee brewing methods, called pour over, hand pour or hand drip coffee, was developed to brew the best tasting coffee, allowing complete control over its quality and flavor. This coffee pour over method is accomplished by pouring a thin, slow, steady stream of water over the ground coffee. s Coffee Filter Cone is ideal for brewing coffee the pour over way. For a perfect brew, place the Coffee Filter Cone over a mug or carafe. Insert a paper or reusable coffee filter and measure in medium-grind coffee, or grind whole beans (approximately 2 rounded tablespoons of ground coffee per 8-ounces of water, or to desired taste). Using just-boiled water, wet all of the grounds slightly and let the wet grounds stand to bloom the coffee for 15 seconds. When grounds mix with water, they expand slightly and release more flavor. Slow and precise water flow is critical to extracting the most flavor with this pour over coffee maker. Pour the remaining hot water slowly and evenly, from the center of the grounds outward, in a circular motion. Allow the coffee dripper to finish dripping. Total brew time should take about 2 to 3 minutes. Remove the coffee maker from the mug and discard the wet grounds. Drink the freshly brewed coffee immediately or let it chill to make coffee drinks. s Coffee Filter Cone, a non-breakable, reusable coffee filter cone, is the perfect portable coffee maker for coffee lovers who like to travel. Easy to use and easy to clean, it's dishwasher safe for easy cleanup. Package Contents: 1 x Coffee filter cone.
