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 cold 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 2 cap colors: Dark Black or Orangey-Red. 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. Food grade silicone. Dishwasher safe. Designed and assembled in USA. Filter + cap made in Taiwan. 100% cotton second-stage filter-bag made in China. Just shake your way to cold brew coffee.

A BETTER FILTER THAT MAKES STRONGER COLD BREW COFFEE: Cold brew experts designed this filter to make professional-quality cold brew in a Mason jar. Our 18/8 stainless steel filter features 200 micron holes, the ideal size for allowing water to circulate and optimal extraction to occur with coarse-ground coffee. It’s a radical improvement to those first-generation brewers with fine mesh screen filters, which are more suited to brewing hot coffee with finer grounds. You’ll taste the difference.
KEEPS COFFEE FRESHER THAN THE COMPETITION: Oxidation is the enemy of fresh coffee, so the key is to keep air out. Unlike traditional sit-on-top mesh filters, our next-generation filter rests fully inside the Mason jar, allowing the Mason jar’s lid to maintain its famous airtight seal. This keeps your cold brew fresher. The intact seal also means the jar stays leakproof, so ours is truly portable and means an end to coffee leaking coffee all over your hands, kitchen and clothes.
NOVEL DESIGN BELOVED BY ITS KICKSTARTER BACKERS: The patent-pending capped-filter design features an ultra-sturdy, dent-resistant 18/8 stainless steel filter, with your choice of color for the food-grade silicone cap. The cap keeps grounds sealed inside the filter, while also working as a shock absorber that prevents rattling and protects the filter. Now you can say goodbye to those flimsy mesh filters that can produce weaker cold brew and easily fray, rip and get clogged up.
BREWING PROCESS IS SIMPLER THAN EVER: Professional-quality cold brew takes less than a minute to prepare at home. After adding coffee grounds and water, just tighten the lid and give the jar a quick shake. That “rumble” step activates the brewing process. Then let it sit overnight and your cold brew will be ready in the morning, tasting like a barista made it. Cleanup is even faster than the prep.
COMPATIBLE WITH STANDARD 2-QUART MASON JARS (NOT INCLUDED): Product includes metal filter with silicone cap and a 100% cotton filter-bag that can be used as an optional second stage of filtration if you have to use fine grounds (remember: it’s best to use coarse grounds for top-quality cold brew). Food-grade silicone cap comes in 2 colors: Dark Black, Orangey-Red. BPA free. Dishwasher safe.
