Before the cup of coffee reaches our lips to take a sip, we have gathered a great deal of information about its taste. We smell the aroma – a good indication of the flavors inside, and we can feel the warmth of the cup through the touch of our hands – a good indicator of its temperature. We also see coffee!

So it will be supplemented or replaced with more relative roast color determinations, such as “light”, “medium” or “dark”. On the consumer side, color is often the first measure of consumer-created quality, making it a basic indicator of sensory quality. In addition, product-specific color changes.
