The Maker:

Established in San Francisco in 2017, Rumble Jar is a line of award-winning cold brew coffee makers designed to keep the brewing process as simple as possible (1 minute prep time) while still producing professional-quality coffee. The secret lies in the stainless steel filter, which was built to the precise specifications of cold brew coffee experts, and then re-engineered it to work in tandem with Mason jars and a wide array of portable water bottles. Their initial product Rumble Jar was awarded as a "Kickstarter Project of the Year" in 2018, and its portable successor Rumble Go was recommended by Outside Magazine.
