Brew smooth, low-acid cold brew coffee with CoffeeSock® reusable cotton filters. Designed for wide-mouth mason jars, DIY cold brew kits, and handled cold brew systems, these filters keep grounds contained while allowing the full flavor of your coffee to shine. Made from certified organic cotton, they are durable, eco-friendly, and reusable for over a year, eliminating disposable paper or plastic filters.

Perfect for home enthusiasts, cafes, and commercial operations, these filters produce clean, crisp coffee with all the richness of cold brew, without sediment or bitterness.

  2. Add coarse coffee grounds and cold water.

  3. Steep according to your preferred brew time (usually 12–24 hours).
