Rumble Jar – Next-Gen Cold Brew Coffee Maker for Mason Jars

Introduction

If you’re looking to make professional-quality cold brew coffee at home, the Rumble Jar – Next-Gen Cold Brew Coffee Maker is the perfect choice. With its innovative design and high-quality filter, you can enjoy stronger and fresher cold brew coffee. This buying guide will help you select the right Rumble Jar for your needs.

Filter Design and Extraction

The Rumble Jar features a 200 micron filter made of 18/8 stainless steel. This filter is specifically designed for coarse ground coffee, allowing optimal water circulation and extraction. Unlike fine mesh screen filters, the Rumble Jar’s filter is ideal for cold brewing and produces a stronger coffee flavor.

Fresher Coffee with Airtight Seal

The Rumble Jar’s filter rests inside a Mason jar, allowing the jar’s lid to maintain an airtight seal. This ensures that your cold brew stays fresh and prevents oxidation. The airtight seal also makes the jar leakproof and portable, eliminating the risk of coffee spills.

Durable and Innovative Design

The patent-pending capped-filter design of the Rumble Jar features an ultra-sturdy 18/8 stainless steel filter. The filter includes a food-grade silicone cap, available in multiple colors, that keeps coffee grounds sealed inside while acting as a shock absorber to protect the filter. This design eliminates the issues of flimsy mesh filters that can produce weaker cold brew and easily fray, rip, or get clogged up.

Simplified Brewing Process

The Rumble Jar makes brewing professional-quality cold brew coffee at home incredibly simple. After adding your coffee grounds and water, tighten the lid and rotate the jar horizontally/sideways 2 or 3 times to activate the brewing process. Let it sit overnight, and your cold brew will be ready in the morning. Cleanup is quick and easy too.

Compatibility and Capacity

The Rumble Jar is compatible with wide-mouth 32oz Mason jars (not included). The filter, made of stainless steel with a food-grade silicone cap, is designed specifically for wide-mouth jars. It’s important to note that the stated 1-quart capacity refers to the volume of the Mason jar, not the filter itself. The Rumble Jar is BPA-free and dishwasher safe.

Conclusion

If you’re looking for a next-gen cold brew coffee maker that produces professional-quality cold brew coffee, the Rumble Jar is the perfect choice. Its innovative design, durable filter, and airtight seal ensure stronger and fresher coffee every time. With its simplified brewing process and compatibility with wide-mouth Mason jars, the Rumble Jar is a must-have for any coffee enthusiast.

    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.

    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 combo, agitate, and let it sit. (The agitation is really cool to see, also!!) It’s such a low effort for high output of a large amount of excellent coffee. One mason jar for me is good for two days of coffee. It’s strong, tastes amazing, and is so simple. From my perspective, it will be worth the purchase after 3 uses because I will have saved 3 plastic cold brew bottles from the grocery store. I am eager to see how well the metal will hold up, but the metal looks so much more durable than some of the dupes I’ve seen on Amazon or even Aldi.
    If you are searching for a reusable and SIMPLE way to make iced coffee all summer, here is your new thing!!! If you are searching for a coffee-making option for traveling/camping/eco friendly-ness, INVEST here.

    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.

    This filter is the best, can use it in any pitcher of water to make cold brew. Highly recommend getting one and stop buying over priced coffees at your corporate coffee shop!

    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.

    I have made one batch. I’m not sure how much brewed coffee it is supposed to replace. I made iced coffee with it and it was delicious. There is a lot left. I was ready to strain it through the cotton bag provided. But I didn’t need to. I used coarse ground coffee as suggested, and it did not leak out. So far I am very happy with it.

    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.

    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!
