One: Insert the rubber stopper firmly into the bottom of the Filtron coffee bowl.
Two: Place a clean filter pad securely in the bottom of the coffee bowl, tab side up.
Three: Place a paper filter in the coffee bowl.
Four: Weigh and grind the coffee. Add coffee to the bowl, then place grounds guard on top of the coffee bed.
Five: Place the water bowl on top, and add 1.9 liters of cold filtered water into the bowl.
Six: Place the Filtron system in the refrigerator for 20-24 hours.
Seven: Remove the Filtron system from the refrigerator, hold over the decanter, and pull the plug to drain. Rest the Filtron on the decanter, and allow to drain for ~1 hour.
Eight: Once the coffee has drained, remove the Filtron from the decanter.
Nine: Dilute the coffee concentrate to taste. Start with 2 parts filtered water to 1 part coffee. Pour over ice, and serve.
Brewing Tip № 1: Making cold brew coffee in the refrigerator produces a much cleaner cup than brewing at room temperature. Coffee left to steep at room temperature has the tendency to taste woody and flat.
Brewing Tip № 2: Depending on the batch size you want to brew, the recipe can be scaled up or down. Use a ratio of 1 part coffee to 4 parts water, by weight.
Grind Tip: All grinders will produce a mix of course and fine particles – none are perfect, however, burr grinders produce far more uniformity. If your resulting cup is too strong and/or bitter, adjust your grind slightly courser. If it is too weak and/or sour, adjust slightly finer.
