Cold Brew Cotton Coffee Filter

We've been loving cold brew coffee with its rich, smooth taste for the past few summers. And are so excited to find this Cold Brew filter from CoffeeSock! This reusable filter is made by lovely hippies  in Texas (they exist!) from organic cotton.

Super easy to use - just put ground coffee into the cold brew filter, place the filter in a container, add water, and let sit at room temperature or in a fridge for 12-18 hours. Remove filter (squeeze to get out every last drop of that black nectar), and you're done. Your cold brew coffee will last 3 or 4 weeks stored in the fridge. Or so I'm told. Mine always gets consumed faster than that! 

The filter is designed to fit with a standard wide-mouthed mason jar. Or you can use any pitcher, jug or container you have on hand to make a delicious, smooth cold brew coffee. Cleanup is quick and easy - empty filter of grounds (compost or add to your garden), rinse and hang to dry. And your cotton filter should last a year or more with regular use. 

We make our cold brew strong so it can be diluted to taste. We use 6 oz / 165 grams (about 1 ¾ cups / 400 ml) of ground coffee to 4 cups / 1 L of water. Yes, you read that right! After diluting, we end up with about 2 quarts / litres of cold brew coffee. We mix one part of our cold brew concentrate with 2 parts of water, ice, milk or cream. You can even add hot water to make a hot coffee with this concentrate! See the full recipe on The Scoop.
