The most proven Japanese coffee brewing methods, called pour over, hand pour, or hand drop coffee, were developed to brew the best coffee, allowing complete control over its quality and flavor. This coffee pour over method to brew coffee is accomplished by pouring a thin, slow, even stream of water over the ground coffee. The coffee filter cone is how to make good coffee using the pour over coffee method. For perfect brewing, 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 desired taste). Use freshly boiled water and slightly wet all the grounds and let the wet grounds stand to bloom the coffee for 15 to 30 seconds. When grounds mix with water, they expand slightly and release more flavor. Slow and precise water flow is crucial to extracting as much flavor as possible 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. Let the coffee dripper finish dripping. The brewing time should take about 2 minutes. Remove the coffee maker from the mug and discard the wet grounds. Drink the brewed coffee immediately or let it cool to make iced coffee drinks.
