Best Rumble Jar in 2026

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.

✔ A TRULY PORTABLE COFFEE MAKER - Simply drop this lightweight 2.8oz Rumble Go filter into a compatible water bottle, and you've instantly transformed it into a portable cold brew coffee maker. The brewing process couldn't be easier: just add coffee grounds to the filter and water to the bottle, then seal it up and give it a "rumble" (i.e. rotate bottle horizontally 2 times), and your coffee is now brewing! By morning, you'll have cold brew coffee as good as the stuff the pros make.

✔ COLD-BREWING IS THE SIMPLEST WAY TO MAKE COFFEE OUTSIDE YOUR HOME - Now you can make coffee just about anywhere you go, since there's no need for heat or electricity. With Rumble Go you can brew coffee whether you're camping, picnicking, driving, traveling for work or relaxing at the beach. All you need are grounds, lukewarm water and time. Rumble Go takes portable to the extreme. No glass bottles to break. No disposable filters to forget. No fragile parts to protect. No gizmos to charge.

✔ UNIVERSAL DESIGN HAS AN EXTENDABLE BASE THAT FITS MANY 16-32OZ WIDE MOUTH WATER BOTTLES & INSULATED TUMBLERS - Rumble Go’s universal design features an extendable base that adjusts by up to 1.5” to allow it to fit many of the leading WIDE-mouth water bottle and insulated bottles on the market, including Hydro Flask, Klean Kanteen, Nalgene, CamelBak, Fifty-Fifty, Mira, RTIC and more. See the compatibility list in the image gallery for more info and tips for measuring your own bottle.
