What is the main purpose of a coffee scale?

The main purpose of a coffee scale is to measure coffee and water precisely. Precise measurements are essential in coffee brewing to ensure consistency and quality in the final cup. When brewing coffee, the ratio of coffee to water plays a crucial role in extracting the right flavors. By using a scale, baristas and coffee enthusiasts can accurately measure both coffee grounds and water, leading to a more controlled and repeatable brew process. This precision allows for adjustments in strength and flavor depending on personal preferences or specific coffee types.

Other choices relate to aspects of coffee preparation but do not capture the primary function of a coffee scale in the brewing process. Brewing time, roasting, and freshness are important factors in coffee but are not directly related to the scale's main purpose.
