What Makes It Mighty?
- converts traditional mason jar into a simple cold brew coffee system
- reusable secondary cotton filter is machine washable
- lid and filter made from food grade silicone and 304 stainless steel
- 32oz Wide-Mouth Mason Jar (traditional)
- Stainless Steel Cold Brew Filter
- Food-Grade Silicone Cap
- Cotton Sock (optional 2nd stage filter)
The Cap—Rumble Jar's secret sauce. Our patent-pending cap design allows the filter to be fully-nested inside the Mason jar, without interfering with the Mason jar's natural seal. As a result, your coffee stays both leakproof and airtight.
The Mason Jar—An ideal brewing + drinking + storage vessel with a legendary seal. Our patent-pending design keeps the seal intact, allowing your coffee to stay fresher since the jar remains airtight and more resistant to oxidation (aka the "coffee killer"). A good seal also keeps it from leaking all over your hands and kitchen.
Steeping time at room temperature: 8-12 hours.
Mighty Rating:
Package free; primarily compostable except very minor components (e.g. plastic toggles or small stickers)

It's easy to brew the night before, using the mason jar to measure liquid and adding the appropriate ratio of freshly ground beans. We always do a second strain through either the fabric bag or a paper filter in a cone, and the coffee is so smooth and delicious. We recommend this to anyone with a cold brew habit – you won't regret it!
I recently discovered a fondness for cold brew coffee. Coffee shops can be pricey and store bought vary in quality. Now I use coffee that I like and save money. It’s simple to use and I feel like I’m treating myself.
My rumble jar has saved me so much money and time as the cold brew i make is just as good as Starbucks as long as you use fresh beans. I just started making a concentrate for espresso martinis too. 🙂
This Rumble Jar is GREAT for cold brew coffee! "Easy to use" is the best description for this product! I made some Michigan Cherry cold brew, and it was delicious with vanilla oat cream. Endless possibilities to enjoy!
This is my new best friend. So easy to prep the night before and have awesome coffee in the morning. Only downside, which one of us gets to use it? Solution? Buy two 😊
About Rumble Jar
Coffee...we drink a lot of it. That was our "coffee expertise", at least until early 2017 when Karl got fed up with all of the existing cold brew coffee filters out there and started hacking away on some new ideas he came up with to make a better one. Hans remained skeptical. But Karl converted Hans to cold brew through a combination of sorcery and brainwashing (i.e. having him taste it) until Hans capitulated and saw the light...cold brew was better! Both of us are product designers and creators, and while we're pretty good at developing concepts, we're even better at finding folks who have real expertise to make our ideas come to life. We hunted around and linked up with the perfect manufacturing shop that strictly works on coffee devices, and off we went to designing, prototyping and playing with our different ideas. And talking to the cold brew experts...folks that didn't just learn about it yesterday, but have been seriously playing with cold brew for 10+ years, before anyone was really selling it. This group of folks had seen and made it all, so when they said, "Wow this is a really good idea," we knew we were onto something! So in late 2017, we brought Rumble Jar to life on Kickstarter. Rumble Jar's reception was pretty mind-blowing (over $50K raised in 3 weeks)! People were actually getting excited about a fairly simple cold brew coffee filter that didn't even have a single moving part. So if Rumble Jar can make it on Kickstarter, it can make it anywhere! -Hans & Karl
