(32oz Filter only w/ Dark Black cap) - Rumble Jar - Next-Gen Cold Brew Coffee Maker for 950ml Mason Jars - 200 Micron Filter Is Ideal for Coarse Grounds & Stronger Coffee - Includes Cotton Filter S...

Love this thing so much. I can make coffee so much quicker now and with less thought. I previously used the OXO cold brew maker and was finding after about a year that it wouldn't drain well, even using a coarse grind. Also, the plastic container holding the brew had gotten scratched pretty good on the bottom where I would scrape it to force it to drain. While the plastic was noted to be BPA-free, it still weirded me out what else could be leaching into my coffee from those scratches. It was just so frustrating. The Rumble Jar is consistent and there's no fuss about draining anymore. Being stainless steel, there's no worry about it leaching any chemicals, unlike the scratches plastic. Plus, since it fits in a mason jar, I can brew it in my fridge now. The OXO brewer was too large for my fridge, so I would brew on the countertop, making my first couple cups warm, which I didn't like. Now it's cold from the first cup using the RJ. Really easy to clean. I just dump the used grinds into my compost bucket and wash the rest out. It would be even easier to clean if the bottom was detachable, though. You can't really make concentrate with it like I could with the OXO since the water needs to cover the column. So, I brew it with grinds up to the second notch and don't dilute it. Filled with water to the top of the 64oz mason jar to brew, I get about 49-50oz of net coffee. It's the perfect amount for 3 days for me, personally. I wish the silicone lid fit on the top of it a little snugger. I have noticed once or twice that the lid had just about come off while brewing when I went to drain it. It has just a small lip that fits over the top. Be gentle with your inversions and fill the mason jar up to the very top with water to prevent that. I can make the coffee and drain it with this, both quickly and consistently. Quick and easy cleanup. Wish I had searched for something like this sooner.

Being recommended this product from a colleague I was uncertain of how successful it would have been, alas I pleased to report i LOVE the product and would be again as a gift for my coffee loving friends.

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.

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.

This filter is designed for use with a mason jar, but I ordered it hoping to use it with a larger pitcher. It works! My pitcher’s neck is a little wider than a mason jar’s, so I need to be careful with the filter lid to make sure it doesn’t slip off the filter (I think the seal could be a little tighter), but it’s still very easy to use. Way less mess than just mixing the grounds and water together and filtering later. My partner thinks there’s a slight taste difference because the grounds don’t come into as much contact with the water when using the filter, but I can’t notice a difference, and did I mention the quick clean-up?! The filter is also great for iced tea. I haven’t tried this yet, but you could use it for infusing spirits, too (you’d still want to use something with a finer mesh, like cheesecloth, to get all the stray bits).
