Reddit reviews BUNN 10GAL23X9 Commercial Coffee Filters, 10 Gallon Urn Style (Case of 250)

I used these filters plus 150g of coffee + ~6 cups of water per jar - a mix of 8 o'clock coffee and Starbucks. Both were whole bean, various dark bean flavors. I ground them in a regular electric coffee grinder on coarse (maybe I'm just used to doing that for French press), distributed them to their filters, rubber banded them, and stuffed them into 1/2 gallon mason jars. I am looking for larger, wider-mouth jars on amazon ATM because the only difficulty is trying to squeeze the water-laden filters OUT of the jars after brewing is complete. They usually tear, which isn't a huge deal, as I pour all of the coffee out first.

Once done, I'll have 3.5ish jars of cold brew coffee. At 150g, it's just the right strength for me. I usually don't take cream or use ice. I don't know how long these keep in the fridge because I've always drank it all within 2 weeks. I've heard anywhere from 2-4 weeks for shelf life. I may save a bit in a smaller mason jar for a month to test that out.

6 cups of water to 150g water seems to be about the perfect mix after much trial and error.

And yes, there is a definite quality difference between coffees. Mixing 8'oclock and Starbucks is a good taste for me that's not terribly expensive. I'd love to find a nice dark bean as oily and rich as SB but cheaper online - any suggestions?
