Honey treatment means that the pectin layer of coffee beans is very sticky before exposure, and the sticky feeling is like honey. When the coffee pulp is separated from the coffee beans, the pectin layer coated by the outside is exposed to the sun, absorbing moisture from the air and making the pectin layer sticky.

Starica growers grade honey-treated green coffee beans according to the color of the coffee. There are three levels: yellow, red and black. The change in color results from the length of time the coffee is exposed to light during drying.

Yellow honey treatment of green coffee beans the longest light duration. Longer light means hotter, so the coffee dries within a week. In general, coffee drying time depends on local climate, temperature and humidity conditions. The drying time of red honey-treated green coffee beans is 2-3 weeks, usually due to weather or placed in a dark place. If the weather is fine, growers block some sunlight to reduce the amount of light. Black honey-treated green coffee beans dry longest in the dark, and the shorter the illumination time. The drying time of this coffee is at least 2 weeks. Black honey green coffee beans processing process is the most complex, the highest labor costs, and therefore the most expensive.
