4 Best Rumble Jar Cold Brew Coffee Makers for 2026 – Expert Quality Picks

Customer Review: I am beyond impressed with this 64 oz Mason Jar Cold Brew Coffee Maker! From the moment I opened it, I could tell the materials were high quality. The glass feels thick and durable, not flimsy at all, and the components fit together securely without leaking or feeling loose. It has that sturdy, well-made construction that instantly gives you confidence it’s going to last. Making cold brew with it was incredibly easy. Just add your grounds, pour in water (into the filter and over the grounds) let it steep, and you’re done. The filter does a fantastic job, smooth coffee, minimal gritty residue, and a clean, rich flavor every time. Cleaning is just as simple, which is a huge win for me. Everything rinses out easily, and the wide mouth makes it super convenient to wash thoroughly. No awkward scrubbing or trapped grounds. I may have thrown mine in the dishwasher! The 64 oz size is perfect for prepping multiple servings at once, which saves time during busy weeks. If you’re on the fence, don’t be, this is a high-quality, user-friendly cold brew maker that delivers exactly what it promises! Highly recommend! ☕️

Customer Review: 5/12/25: UPDATE: The pot works fine. One thing drive me to using bad words. I said this before, but it is an irritant. They attached the handle to the lid. Plastic lids are hard enough to use on glass jar. Having a handle in the way so that you have to remove you hand with each turn is frustrating. Fir someone new to what cold coffee brew represents, this is a good starter pot, or I frequently used pot. The instruction page presented a problem. Simple answer: go online and get detailed instructions on just how to make cold coffee. Now, the simple instructions manuel is a fine reminder. Packaging handled the trip thru shipping very well. It is glass. It was double packed. There were many choices of cold brewing containers. Considering the cleaning process I go thru with my automatic tea pot, I opted for simple. Simple is very easy to clean with no over-engineered top to take apart to clean. Small enough for refrigerator or counter. The gaskets didn’t look sturdy to me, but after use and washing, I think they will be just fine. It’s hard for the plastic lid to screw on and off because of the handle, but I succeed. I use a standard tube sponge to clean the filter. Works better.

Customer Review: It’s a great product. Simple well built easy to use. I’ve only used it twice. First I tasted the coffee at different times: four hours, 6, 8, 12, 24. To see the difference that made. I didn’t like any of it. In fact I couldn’t drink it and threw it all out. Not the coffee maker’s fault. I just don’t like cold brew. It even makes me feel sick. I drink decaf for the flavor of it. I like a deep rich coffee flavor. I like a medium roast sweet coffee bean espresso. Cold brew just doesn’t taste anything like that. It has its own taste which is very mild and smooth or flavorless depending on your attitude. But it does extract more caffeine from the beans even my decaf beans made coffee too caffeinated for me. I also extracted some other stuff from the beans my espresso maker doesn’t having a totally different effect on that. I didn’t like. I recommend trying cold brew before getting into making it yourself but my coffee shop doesn’t have decaf cold brew so I had to buy this to see for myself. If you like cold brew this is a great way to go. Aside from changing the time of the brew you can play around with adding paper filters inside the metal filter or filtering the coffee after it’s done but I didn’t mind the slight sludge on the bottom of my coffee cup. So the machine is simple easy to use works well easy to clean. Great if you like cold brew but it’s a completely different type of coffee.

Customer Review: I love this. It is not like pressing a button and coffee comes out, but cold brewing coffee is a bit of a process and should be, because it needs to sit for 12-24 hours. It is pretty easy to clean, simple to use, and the glass jar washes easily and does not stain. Coffee stains like a b….

Customer Review: For the amount of coffee beans I dump into my percolator to make one cup of strong coffee, I thought I would be better off making cold brew and squeezing every last drop of caffeine out of my beans. This pitcher is functional, easy to clean, screw together, and has the little measuring tick marks on the side. For $20 it’s a great deal. I’m now enamored with the whole mason jar thing and it’s appealing to have a giant mason jar pitcher. Also the plastic lid screws on tight, my arms being stronger than some, so I had to be careful not to screw it on tighter. It’s a 64oz mason jar, but with the filter filled with 8oz of ground coffee it’s slightly less. The instructions say to use 8oz of coffee grounds with 64oz water, I didn’t come up with that myself. Also, you have to grind your own beans: the pre-ground beans from the store are too fine and seeped out of my metal tea strainers that I already had from a different brand/appliance. I didn’t experiment with putting store bought grounds in this strainer, no desire to potentially drink coffee with fine grounds in it. So in addition to this pitcher I ended up buying a Black&Decker basic coffee grinder, to get coarse grinds. I also labeled the lid with the date/time my 24-hour batch would be ready, with a red wax pencil. you can use masking tape or whatever, sharpie washes off plastic with dish soap sometimes. Overall this is a decent pitcher for making your own cold brew coffee.

Customer Review: Why pay high prices for coffee shop cold brew when you can easily make your own at home? This cold brew coffee maker is simply amazing! It’s super easy to use, easy to clean, and delivers great taste and convenience at a fraction of the cost. The 64oz glass jar is sturdy and well-made, and the stainless steel filter works perfectly. It’s also fun to use with family — everyone can craft their own unique blend of decaf or caffeinated cold brew to suit their taste. Choosing the right coffee beans makes all the difference! Highly recommended — great price, excellent build quality, and a must-have for any coffee lover.

Customer Review: I bought this product after experiencing Cold Brew for the first time and I have NEVER looked back. Just today this product died after two years of VERY heavy use. I would brew a 64oz mason jar of Cold Brew twice a week, sometimes 3 times even, without a break and the coffee always came out pure, clean, and free of coffee bean that can sour any caffeinated journey, while maintaining a high quality of flavor that made it through. The Pro’s: Easy to use! Just throw it in the jar, add 2-4 scoops of your favorite coffee (I did the Colombian Roast) and add water. Refrigerate overnight for 12 hours and you have a full pot! The Con: Cleaning it was a bit of a pain, though hardly unmanageable, and it did gain some stains from constant use. Good Product, good results, and good coffee, what more can you ask for? Would recommend!

Customer Review: Cold Brew Coffee Maker for Wide Mouth Mason Jar is a wonderful item for those interested in making cold brew coffee at home! It comfortably sits in a 64oz mason jar, a perfect fit for better volumes. The style is basic but works well since it allows good flavor with every cup. The mesh filter makes certain that the coffee grounds are held in place resulting in a nice cold brew. It’s also quite easy to maintain and very sturdy so I suggest directing high-pressure water from the outside towards the inside to help keep the filter clean. This coffee maker is a must-have for anyone who loves to drink cold brew and I do not even want to think how would I be brewing without this one. Definitely recommend this to anyone who would like to brew their own cold brew!
