EASY TO USE Simply pour coarse ground coffee into the filter basket, add water and allow to steep for 24 to 48 hours. Remove the filter basket and discard the grounds and you have 1.5 quarts of delicious coffee concentrate. All components are dishwasher safe. CREATE CONCENTRATED BREW Our large filter basket allows a high ratio of coffee grounds to water to make a strong concentrate. The silicone seal allows you to shake the jar during the brewing process ensuring that all of the grounds are completely wetted. HIGH QUALITY MATERIALS Our jar is a Ball 2 quart mason jar made from durable soda lime glass. The filter is made from heavy gage, food grade stainless steel wire that will not bend or dent. LARGE AND VERSATILE BREWER The 2 quart jar will yield up to 1.5 quarts of coffee concentrate. Because we use a standard mason jar, you can add your own jar to the system to brew one batch while drinking another. This system can also be used to make cold brew tea or sun tea with loose leaf teas and infuse water with fruits or oils with spices. COLD BREWING BENEFITS Cold brewing coffee prevents the formations of acids that create bitterness and obscure the flavors of the coffee. The low acid content of the coffee is also a benefit for reflux sufferers. In addition, the stainless steel filter allows the aromatic oils of the beans that are removed by a paper filter to pass through into the coffee further improving the flavor.
