This plastic-free brewer uses a quick heating element that consistently delivers 195°F to 205°F water. Every part touching water (cold and hot) and coffee is plastic-free. The wide showerhead and Bloom function work with the correct water pressure, drip distance and #4 filter shape to create even saturation. It is designed to deliver on flavor. The approx. 6-minute brew cycle will produce optimal extraction. Brews coffee with round, rich flavor, and no bitterness every time!
