Rumble Jar - Next-Gen Cold Brew Coffee Maker for Mason Jars - 200 Micron Filter Is Ideal for Coarse Grounds & Stronger Coffee - Standalone Filter (no Mason Jar included)
- 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 it's 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 rotate the jar horizontally/sideways 2 or 3 times. This "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 WIDE-MOUTH 32OZ MASON JARS (NOT INCLUDED): Product includes a stainless steel filter with food-grade silicone cap and a 100% cotton filter-bag that can be used as an optional second stage of filtration if you brew with fine grounds (remember: coarse grounds are best for cold brew). Compatible with wide-mouth Mason jars only (i.e. not regular mouth jars). The stated 1-quart capacity represents the volume of the Mason jar, not the volume of the filter. BPA free. Dishwasher safe.
- Color: Filter only w/ Orangey-Red cap
- Size: 32oz
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 great 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. The 200 micron holes are the ideal diameter for cold brew made using coarse grounds, which is the grind size experts recommend for cold brew.

The cap is made of food grade silicone, and it keeps grounds sealed inside the filter and out of your coffee. The filter is designed to be fully-nested inside the Mason jar so that no part of the filter 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. Mason jar made in USA. Filter + cap made in Taiwan or China. 100% cotton second-stage filter-bag made in China. Choose from 3 cap colors: Dark Black, Orangey-Red or Kickstarter Green.
