Rumble Jar Filter

Rumble Jar was awarded as a Kickstarter Project of the Year in 2018 for its design of a high-quality cold brew coffee filter that works in tandem with the classic Mason jar. This filter (plus a Mason jar) is all the equipment you need to make professional-grade cold brew coffee right at home. Just take your favorite coffee beans, grind them coarsely, add water to the jar 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. This filter is compatible with wide-mouth one-quart/32oz Mason jars (not included) or a standard half-gallon/64oz Mason jars (not included) depending on the filter size you choose.

Includes:  + 18/8 Stainless Steel Cold Brew Filter + Food-Grade Silicone Cap, Available in Dark Black + Cotton Sock (optional 2nd stage filter)
