How to Make Cold Brew with the CoffeeSock Coffee Resource Surely you’re all familiar with cold brew by now. We’ve covered how to make cold brew on the regular, how to make cold brew in a French Press, the pros and cons of the cold brew process…but we love it, so here’s another way to make it- in the CoffeeSock! About CoffeeSock Image credit: coffeesock.com Based in Austin, Texas, CoffeeSock became a reality in 2011 when an “a-ha!” moment turned into a legacy. According to the company’s About Us page, this moment occurred when the founders were traveling and the only thing available to make coffee was a filterless Chemex and a Chorreador, a Costa Rican “coffee sock”. So, they fashioned the fabric filter from the “sock” portion of the Chorreador to fit over their Chemex. While enjoying coffee they otherwise wouldn’t have had, they marveled at how well this quick fix had performed. Keeping the idea in mind, once they returned home, they got to work. After creating a prototype, the founders started offering test models for sale. Soon enough, the product was so well-received that the business concept was pursued in full force. “What’s in a name?” With large-scale success on the horizon, the owners devoted their full attention to coming up with a brand. Knowing they wanted a business centered around family and that they wanted to change the world, CoffeeSock was born. 6 years later, mission accomplished we’d say! That’s exactly what CoffeeSock is and the founders certainly have shaken up the coffee world with their invention. They have grown exponentially from the one pour-over test model to a company that now offers a myriad of filters designed for all popular brewing methods, including cold brew. Hallelujah! With partners like Starbucks and Williams-Sonoma, it looks like CoffeeSock isn’t going anywhere anytime soon. How to Make Cold Brew in the CoffeeSock What you’ll need: CoffeeSock Cold Brew Kit 2 cups ground coffee, coarse grind (for a 1/2 gallon); 1 cup for 1 qt.

Author’s Afterthought: I made cold brew in the quart size container and it came out stellar! I brewed it for 24 hours- cause I like rocket fuel- using a dark French roast (used a medium grind- will definitely go coarser next time).
