Mathematics of gold cup standard. Although it may seem intimidating at first using the coffee brewing control chart will provide for the basic groundwork in which to ensure consistent beverage preparation. Extraction soluble yield if not we can mathematically say that the percentage of the dissolved solid particles out of used ground coffee. The perfect cup of coffee is a product of many variables.

The coffee brewing control chart is an important tool it allows us to know the amount of total dissolved solids in coffee percentage of extraction in addition to other data which make coffee brewing interesting.

We have 4oz of coffee ground in our brew basket. Coffee extraction is the process of dissolving coffee solubles desirable compounds that occur naturally in coffee beans into water. The course takes the scientific knowledge a stage further covering the impact of temperature on brewing acidity levels during the brewing process the impact of water quality on coffee brewing and flavour and understanding how to chart espresso and brew within a given extraction percentage. That means the extracted coffee is just the extraction percentage and the brew water is our ratio.

It is very important to understand the mathematics of the brewing chat to understand the chat itself. The red diagonal lines show how much coffee you started with for example the line labeled 3 75oz 106 grams means you put that much ground coffee into the brew basket. 64oz water 4oz coffee 1 5oz water oz coffee 013 4oz coffee 19 extraction.
