What does the formula "(Yield x TDS) / Dose" calculate?

The formula "(Yield x TDS) / Dose" calculates the extraction percentage, which is a critical measurement in the coffee brewing process.

When you break down the components of this formula, Yield refers to the total amount of brewed coffee produced, typically measured in milliliters or grams. TDS stands for Total Dissolved Solids, which represents the concentration of coffee solubles present in the brew, often measured as a percentage. Dose refers to the amount of coffee grounds used to make the brew, also typically measured in grams.

By multiplying Yield with TDS, you obtain the total grams of coffee solubles that have been extracted into the liquid. Dividing this product by the Dose allows you to calculate what percentage of the coffee grounds has been dissolved in the brew. This percentage illustrates the efficiency of the extraction process, indicating how much of the coffee's soluble material has been utilized, and it is a key factor in assessing the quality and characteristics of the final cup of coffee.

Hence, this formula is essential for understanding and optimizing the extraction process in brewing, making extraction percentage a vital metric for baristas aiming to improve their coffee-making technique.
