Rumble Jar: Next-Generation Cold Brew Coffee Maker for 32oz Mason Jars

clarita apple: I have used a few of the other mesh-type cold brew products and this is much better. It makes a better cup of coffee with less waste and is much easier to clean. I'm really glad I bought it. I'm definitely going to get the Rubble Go version next time I travel. Game changer.

bern2lead: It's so easy to use! I use my own 32 oz jar. You can use any 32 oz or bigger container. Well sealed. Although I use coarse ground coffee beans, it does not spill out. Easy to clean too. This is a very good buy for me.

Karissa: Cold brew is a staple in our house, and over the years we’ve tried everything from compostable single use bags to Coffee Sock to other metal filters. This is by far the easiest and best method we’ve tried! I use regular ground coffee in here which is a huge time saver, leave it at room temp on the counter overnight then filter once through the provided bag. Perfect every time, and really easy to clean up.

Walter Ponce: Easy to use and made a GREAT batch of cold brew. Really impressed with how easy the grinds came out of the tube after.

I paired it with the "Country Line kitchen glass mason jar pitcher with lid" and it was PERFECT!

Add 5 cups spring water, grinds in your filter. Sit on counter for 8 hours and remove grinds, add more spring water to top, pour and enjoy!

The filter even has markings letting you know how much grounds to put in for a regular or strong brew. Like I said, PERFECT!

lauren f: First thing first - I love coffee, but specifically I love iced coffee. Making iced drinks at home was challenging/a hassle because i don't want to invest in a big, bulky coffee maker with iced functions, and coffee pods. I feel they are horrible for the environment and are so wasteful of plastic (like the bottles of cold brew sold at the grocery store, as well). Because of my desire to make the best coffee with the least amount of waste, all of the coffee accoutrement I've invested in is metal, portable, reusable, and durable, like my bialetti moka pot percolator, and a hand coffee grinder for fresh ground beans.
I decided on investing in the rumble jar too, to have unlimited access to iced coffee without a big financial investment or environmental impact. Let me say - the investment was SO worth the $20. I will bring this with me now wherever I go, along with my percolator. Not only is it an awesomely reusable option, it's durable, VERY easy to clean, and gave me the best cup of iced coffee I've had in a long time. It really feels like I have a full barista set up in my house with none of the equipment. At night, I grind fresh beans, dump them in the rumble jar/mason jar...

Gaz Don: The rumble jar is so quick and easy to use it should be used by anyone making cold brew coffee. The clean up is simple. It's one of the best products I have bought. I have had no need to use the cloth filter bag as the cold brew from the filter is perfect.
Fill course grind coffee into the filter.( I like mine strong so I fill up to the 2nd mark and place in kilner jar. )
Fill with bottled spring water then brew for 24hrs in the fridge or 12hrs on the counter. Easy as that.
Buy it and you will not be disappointed.
