Rumble Jar - Next-Gen Cold Brew Coffee Maker for 32oz Mason Jar - 200 Micron Filter Is Ideal for Coarse Grounds & Stronger Coffee - Made Famous on Kickstarter - Includes Mason Jar & Cotton Filter Sock

Fresh off of an impressive Kickstarter debut, Rumble Jar is the next generation of cold brew coffee makers designed for Mason jars, and it will have you making barista-quality cold brew coffee right at home instead of overpaying in stores. This 4-piece brew kit contains a patent-pending filter that was engineered by coffee experts to work specifically for cold brew, and then retrofitted to work in tandem with the classic, easily replaceable and highly durable Mason jar. Rumble Jar is all the equipment you need to make barista-quality cold brew coffee right at home. Just add coffee and water and give it a rumble. Prep time takes less than one minute, and by the morning you'll have professional-quality cold brew coffee ready to drink. The metal filter is made of dent-resistant 18/8 stainless steel. Say goodbye to those flimsy mesh filters you find everywhere, and say hello to this surprisingly sturdy upgrade. 200 micron holes are the ideal diameter for cold brew made with coarse grounds. Plus, the filter includes two notches to help guide you in brewing either normal strength or concentrate strength cold brew. The cap is made of food grade silicone, and it keeps grounds inside the filter, keeping them totally sealed away from your coffee. Choose from 3 cap colors: Dark Black, Orangey-Red or Kickstarter Green. A wide-mouth, quart-size (32 ounce) jar with a 2-piece metal lid is included with every Rumble Jar. The filter is designed to be fully-nested inside the Mason jar so that nothing interferes with that time-tested Mason jar seal. The result is that your coffee stays airtight and the jar stays leakproof. Oh, and clean-up? Never been easier. That's because we eliminated all the unnecessary equipment to help make cleanup a cinch. BPA free. FDA-approved food grade silicone. Dishwasher safe. Designed and assembled in USA. Mason jar made in USA. Filter + cap made in Taiwan. 100% cotton second-stage filter-bag made in China. Just shake your way to cold brew coffee.
