Rumble Jar: Filter Only

Introducing the XL version of the award-winning Rumble Jar. This half gallon version doubles the amount of cold brew coffee you can make, so now you can brew a batch big enough to last for several days. The filter is compatible with standard half-gallon/64oz Mason jars (not included), and together you've got all the equipment you need to make cold brew coffee at home that tastes as good as the stuff you buy in stores. Just take your favorite coffee beans, grind them coarsely, fill up the jar with water and give it a rumble. Total prep time takes less than a minute, and by the morning you'll have delicious cold brew coffee ready to drink. 

The Details:

• 18/8 stainless steel cold brew filter, compatible with any standard 64oz (Half-Gallon) Mason Jar
• Food-grade silicone cap (orangey-red color)
• Cotton sock (included as an optional 2nd stage filter)
• Made in China

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.
