It’s not just a nice looking coffee-making device. The Blue Bottle Coffee Dripper took a lot more effort to design and build than its minimal facade would have you think, with a small team of engineers and scientists working on a better pour-over device through 70 iterations. Notable design elements include forty interior ridges that pull coffee downward by capillary action, a flat bed for uniform extraction, and a precision nozzle that optimizes coffee exiting the dripper. It helps that it’s made of Japanese porcelain for heat retention and pairs well with Blue Bottle’s Coffee Filters made of bamboo-based paper that eschew the need for pre-wetting.
