Total Dissolved Solids Measurement in Coffee is Slightly Affected by Sample Temperature

Coffee Data Science

Collecting data to help define protocol

Quantifying coffee is difficult, but there is a single metric commonly used throughout coffee methods in the coffee industry, Total Dissolved Solids (TDS). TDS is measured using a refractometer and tells you how many coffee solids are in the cup. From this metric, you can derive Extraction Yield (EY) to quantify the efficiency of coffee extraction.

Many propose a stricter protocol for collecting TDS samples. I looked specifically at sample …
