This size 1 coffee filter cone, with a capacity for 1 to 2 cups, is designed for making coffee using manual pour-over brewing—one cup of coffee per brew, no more old or burnt coffee made hours in advance; brew only what you need for less waste. Color: Red Size: 4 x 4 x 3.1 inches Material: Plastic 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 for complete control over its quality and flavor. This pour-over coffee brewing is achieved by pouring a thin, slow, even stream of water over the ground coffee. The coffee filter cone is how to make good coffee in the pour-over coffee method. 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-ground coffee, or grind whole beans (approximately 2 rounded tablespoons of ground coffee per 8 ounces of water, or to taste). Use freshly boiled water, lightly moisten all the ground beans, and let the moistened ground beans sit to bloom coffee for 15 to 30 seconds. As ground beans mix with water, they expand slightly and release more flavor. Slow and precise water flow is crucial to extract the most flavor with this pour-over coffee maker. Pour the remaining hot water, slowly and evenly, from the center of the ground beans outward, in a circular motion. Allow the coffee to drip completely. Brew time should take approximately 2 minutes. Remove the coffee brewer from the mug and discard the wet grounds. Drink the brewed coffee immediately or allow it to cool to make coffee drinks. The coffee filter cone is an unbreakable, reusable coffee filter cone that is the perfect portable coffee brewer for coffee connoisseurs who like to travel. It is easy to use and easy to clean, it is dishwasher safe for easy cleaning.
