Brew smooth Coffee concentrate without taking up precious counter space with the OXO brew compact cold brew Coffee maker. Don't let its size fool you, the Coffee maker brews enough Coffee concentrate to last a week. We kept the design simple; add ground beans and pour water into the rainmaker top, it distributes water evenly over the grounds for a better, richer flavor. Brew 12 – 24 hours on your counter or fridge, then place the brewer onto the borosilicate glass carafe to automatically drain. The ultra-fine, reusable stainless steel mesh filter prevents grounds from escaping into your brew. The carafe stopper has a silicone seal to keep the concentrate fresh. When you’re done, The brewer and carafe nest for easy storage.
