Designed to brew coffee with 67-percent less acid than coffee made with hot brew methods, the Toddy Cold Brew System also makes tea, hot or cold. The patented cold brew system uses regular coffee beans to create a super smooth cup of steaming hot coffee as is often found in major coffee houses, but with no electricity required. The set includes a brewing container with handle, glass decanter with lid, four reusable filters, three rubber stoppers, a set of instructions, and a recipe guide. Get more out of your coffee beans, since the coffee concentrate stays fresh for up to three weeks.
