Cold Brew Iced Coffee Maker for Wide Mouth Mason Jars – Without Coffee Brewing Mason Jar - BPA Free - Made in the USA

I make cold brew at a 1:9 ratio (185g coffee and 1700mL water) in half gallon mason jars. At this amount, it barley fits and I have to stir the coffee a few times to complete the bloom before I can fit the rest of the water. I set my burr grinder between fine and medium.After sitting on the counter overnight, I shake the jar and let it settle for a 2-3 hours. This is important; if I don't do this I usually have a lot of trouble with the filter clogging.I screw the Bruw on the jar with coffee and gently pour into the empty jar. I DO NOT screw the 2 jars together and flip as per the Bruw instructions. Whenever I've followed the instructions, even when using a very coarse grind with 1 qt jars, the filter would clog very quickly and would completely stall out.So I pour gently from the jar with the brew to the empty jar. Do not agitate, keep the angle shallow such that you still have a constant flow. The goal is to keep as much of the grounds/sediment towards the bottom of the jar you're decanting. As the flow slows you can increase the angle or rotate the jar.Eventually it will clog, but usually I've poured off most of 1L by then. When it clogs, I tip the jar back up right and give it a bit of a shake to clear it, then repeat what I was doing before.Once the jar no longer has visible liquid (ie, just damp grounds), you can prep to screw the jars together. Tip the jar upright again and shake to clear the filter, then roll the jar around to try to get as much of the grounds stuck on the bottom and sides of the jar as possible. Now flip it over on top of the receiving jar and let it drip for a few hours. This final drip usually recovers 300-400mL.Now, since this is a metal filter, there will be a LOT of fines. Let your jar sit overnight in the fridge so the fines settle out.All in all, from 1700mL water and 185g coffee I get 1400mL of coffee concentrate. That's over 80% of the input water recovered! With other brewing methods I could never get much above 65-70% recovery.

It gets the job done, but it's messy. I have had difficulty getting the lid to fit properly. I discovered that you must clear off as much of the grounds as you can before putting the jars together and flipping them over to drain. There is no mention of that in the directions. Tapping it didn't help, but tipping the jars to the side did. I wouldn't but this for a friend.

Works like a charm every time. I make a concentrated cold brew by using 1 cup of grounds per 32 oz. container. I then add 1/4 - 1/3 portion of concentrate depending on how strong you want it and fill the rest with water. Heat and enjoy! I prefer using 64 oz. containers so I don't have to mess with it as often but this straw is too short so I bought 3/8" ID food grade tubing and made my own straw for the larger containers. No mess. Easy to clean. Much easier to clean than the filters that rest in the jars, and more durable.

Very nice simple way to make cold brew. Just have to make sure coffee is ground coarse enough...I’ve had to experiment so it doesn’t clog.

I love my iced coffee & tired of paying $2-4 each at the local DD & other shops. I saw this on Shark Tank. Finally, I thought I was going to save a few hundred dollars a year in Cold Brewed / Iced Coffee's. This works nothing like demonstrated. Tried multiple canning jars, including "Ball" brand as recommended. When you turn the jar over to drain your cold brew into the empty jar, it leaks from the seams and in a few seconds the grinds have clogged up the filter. When you shake a little as recommended, you end up with more coffee outside the jars and a giant mess. Great idea, poor design and execution.

This has been a pretty convenient way to make cold brew coffee and tea. My ONLY complaint about the product is that when making cold brew coffee, it can take a few attempts to get going. Once it does however, the coffee is good. Tea gets made a lot faster and it works great for that, too. Worth every penny!

The Mason Jars dont't fit to the screwing mechanism so there will always be a little coffee spilling out. As you need to clean it it's not really an Investment I'd do again - I'll go back to just dumping the cold brew into a coffee filter.If the quality would be a little better I'd rate it 4 Stars but in the end it's something you don't really need :(

I love cold brew coffee and have tried several makers... This one worked the best and I use it every day. I was leary that it wod take too long to drain but the brewed coffee transfers very quickly.
