The coffee concentration (TDS) represents the brewed coffee liquid and the ratio of solid matter extracted,

The higher the TDS value, the higher the intensity (concentration) of the coffee;

The lower the TDS value, the lighter the coffee is;

TDS is one of the direct judgments.

In addition, according to the ratio of “Gold up” coffee defined by SCAA (American Fine Coffee Association) and SCAE (European Fine Coffee Association),

Also look at the "Extraction", through Brix (%) can be calculated: How much solid matter is extracted from the coffee beans?

Coffee with too low extraction rate will sacrifice the layering; on the contrary, when the extraction rate is too high, it will produce bitterness, astringency, or other odor.

◎ According to SCAA (American Fine Coffee Association) and SCAE (European Fine Coffee Association), the "Gold Cup" (Gold Cup Theory),

The TDS is between 1.2 and 1.45%, and the ratio of coffee with an extraction rate between 18 and 22% is taste.

◎The extraction rate can be known by simple calculation: (Brix reading x coffee liquid capacity) / coffee powder weight

◎ Digital display TDS/Brix (%), °C clear and easy to read

◎ Only 1 drop of sample, press the button for 3 seconds to read the value immediately
