Total Dissolved Solids (TDS) Vs. Extraction Yield
UPDATE: We were a bit surprised by the TDS result of the first (fine) coffee, so we went back and measured it again once the coffee had a chance to cool down and got a more accurate result! The result was 1.60, which gives us a much higher extraction yield of 25%, instead of 22.44%. This is why you should always measure TDS three times! 😊
