TDS
TDS (Total Dissolved Solids) measures the total amount of dissolved solids in a solution, expressed in ppm (parts per million) or as a percentage. In coffee, TDS indicates the total concentration of dissolved organic and inorganic compounds in the brewed coffee. This measurement is essential for evaluating flavor, texture, and overall quality. To measure TDS, a refractometer is used,, helping baristas fine-tune their brewing methods to achieve the ideal balance of strength, sweetness, and bitterness.
