Review on ☕ Cold Brew Coffee Filter Bags - Convenient, Disposable, Single-Use Fine Mesh Filter Socks for Concentrate, Iced Coffee Maker, French/Cold Press Kit, Hot Tea in Mason Jar or Pitcher by Debra Brown

Glory! These things really work. You have solved the "sludge" problem in my Oxo Cold Coffee Brewer. 10 ounces of coarse coffee (3.5 cups) took 4 brew bags (last 3/4 full). They were soaked for 24 hours with occasional gentle shaking and then drained. A gentle squeeze added nearly 1/4 cup of flavor to the carafe. There is less than a teaspoon (i.e. sediment) left in the brew tank. Yield increased from 2.5 cups to just over 4 cups. Sometimes the simplest solutions work best. (UPDATE - 0723/2021) Now uses 12 oz coarse coffee and four 24 hour soak bags. There is virtually no sediment (I grind at Whole Foods). Remember to gently tap the bags on the counter to fill them up as much as possible. I have about a tablespoon of ground left (Allegro Extra Dark French Roast whole beans come in a 12-ounce bag).
