The immersion dripper is designed to allow the coffee ground and water to sit together for a set amount of time. When the coffee is finished being extracted, simply press the switch lever and the coffee will flow into the server (sold separately) beneath it. The spiral ribs on the dripper allow air to escape while brewing so the coffee beans have more room to expand and provide greater extraction. This method allows the coffee's deep, rich umami flavors to seep into your cup, and the finely woven filter creates a clean, smooth extraction. The dripper is made out of durable, heatproof glass that won't transfer odors or colors. 
Available in 2 sizes.
