(2-Pack, Large 12in x 12in) Organic Cotton Cold Brew Coffee Bag - Designed in California - Reusable Coffee Filter with EasyOpen Drawstring Cold Brew Maker for Pitchers, Mason Jars, Toddy Systems

I can't speak for different qualities of bags as this is the only one I've tried but it worked flawlessly first time, coffee came out silky smooth and cleanup was surprisingly easy, tip the majority of the grounds out and rinse the rest off from both sides of the fabric

Love the quality of the bags and they are lovely and big. I have used a 2litre Mason jar to make my cold brew and I'm very excited to try it in a few hours to give the coffee beans the full 24hrs. Would definitely buy again.

Just brilliant. Easy to use and clean. Turns what was a really messy long winded process into a a super quick task. I do mine in Sunday’s, pour it into a bottle Monday morning, job done. Takes minutes because of this bag.

The media could not be loaded.  Before the Doppleganger cotton filter bag I tried a hemp filter bag, this one has a noticeably finer weave. If you have ever used a french press then you know the trade off - Things that filter out more sediment produce a different and usually somewhat weaker flavor since they filter out more of the natural oils from the beans (And keep in mind that cold brewing already requires more grounds to get the same strength of coffee that you would get from brewing it hot). While I like the taste of less filtered coffee there is a point where the sediment is too annoying to be worth it, and I'd imagine that point will be different for every person. These filter bags did an excellent job of filtering out almost all the sediment and surprisingly the flavor was actually just as good and maybe even a bit better than the hemp filter bags I tried before (which left almost a half inch of sediment in the bottom of my pitcher). They seem to be of good construction as well, and I'd imagine will last me quite awhile. I would highly recommend trying these filter bags for making cold brewed coffee, even if your a person who normally will put up with a lot of sediment in your coffee for the arguably better flavor that less thorough filtering provides.(Update) Having used the bags a few times now, I have some advice:I can't claim credit for this idea, as I saw it on the instruction for another filter bag, but turn the bag inside out before you use it so the seams are on the outside. It makes it easier to clean afterwards.And on the subject of cleaning the bags I'd say the easiest way of cleaning them is to dump as much of the coffee grounds as you can into the garbage as soon as you take the bag out of whatever pitcher/container you were cold brewing the coffee in. Then let it sit somewhere to dry ( if your in a big hurry you could put a small fan on it). Once it's completely dry you'll find it much easier to shake the remaining grounds out before rinsing the bag, and trust me, you don't want to make a habit of washing any amount of coffee grounds down a sink drain.

I would only recommend this product for standard pitchers, NOT FOR WIDE MOUTH MASON JARS. Definitely not for narrow mouth mason jars.It tools me 10 minutes of pulling and twisting and yanking the bag, while digging coffee grounds out of the bag by hand, to finally get this thing out of my 64oz wide mouth mason jar. It’s didnt save me any time over filtering through a #2 drip cone, and I didn’t have any less sludge in the bottom than I get from in a French press. I already went and ordered a metal mesh tube for making cold brew in my mason jars. Guess these will become two $7 produce bags :/

I bought this because two of these were about the same price as a single CoffeeSock, and they said 100% organic cotton.The thread was clearly not cotton, It was very plastic like. The drawstring is also plastic, though this is clearly marked in the description, I had missed that, so there was no chance I was keeping this product.There's no point in cutting out the plastic by using cotton if it's just going to have plastic thread and drawstring anyways. That's a pointless compromise, and therefore a pointless product to me.I have now bought a CoffeeSock, and am happier with it.

I make 1-2 gallons of cold brew a day. These filter bags are the best I've used, and after 10 months, they still provide great filtering. Following the directions of cleaning up with warm/hot water is the best method to keep the cotton durable. The only "super clean" I occasionally do is to soak the bags in hot water overnight with some dish soap.Highly recommended product sold on Amazon.

I made my first batch of cold brew last weekend using this filter. It fits really well around the lip of my 2L pitcher and didn’t move while I added in the grounds. Nothing leaked out of the bag during the brewing process and the end product tasted great. I like toddy-style cold brew and I think this is an improved version of that. The bags are easy to store and fairly easy to clean. Some grounds got stuck in the drawstring area of the bag, but I was able to get most of them out by soaking the bag in a bowl. I highly recommend these cold brew bags!
