Slow drip coffee, also known as Kyoto-Style coffee, is a coffee brewing style that was made popular in Kyoto, Japan.
In this brew method, coffee is made by letting water drip slowly, drop-by-drop, over coffee grounds, which better captures the flavor of coffee over immersion of coffee grounds in cold water. This brew method makes light, and flavorful cold brew.
This cold-drip coffee is made in a three section instrument or brewer. Water is poured over the top section of the brewer, which then slowly drips down into the middle section. Coffee gounds (coarse) are placed in the middle section, and as each drop works through the coffee, it drips into a collector at the bottom of the of the brewer.
This slow drip coffee takes roughly about 4 - 12 hours depending upon the desired amount.
