A tool for determining the appropriate amount of ground coffee and water necessary to produce cold brew coffee concentrate, allows for precise adjustments based on desired strength and batch size. It functions by accepting inputs for coffee-to-water proportions and target volume, then calculating the required quantities. For example, if one aims for a 1:8 ratio and a final volume of one liter, the tool determines the necessary grams of coffee grounds.
The use of such a tool offers several advantages, including consistency in flavor profile and reduced waste of coffee grounds. Historically, cold brew recipes relied on approximations, leading to variations in each batch. The advent of this instrument standardizes the process, enabling repeatable and predictable results. Furthermore, it assists in scaling recipes up or down efficiently, which is particularly useful for both home brewers and commercial coffee establishments.
