Traditionally the colour of coffee has been used to determine the degree of roasts and to enhance consistency in the end product. Nowadays, roast temperatures are recorded to allow the reproduction of previous roasts. However, roast profiles vary widely across different conditions and roaster designs. Thus, to compare roast levels in an unbiased way, Tonino maps the colour of ground coffee to a numeric scale independent of the production process.
