Coffee Farming/Cheatsheet

Dealing with coffee includes some calculations and approximations. We aim to collect all the relevant numbers for that here.

Weight and value conversions
Notes:
 * "ICO": refers to an agreed standardized value of the International Coffee Organization.
 * Soluble coffee = dissolved solids. The factors for (decaf) soluble coffee can also be used for liquid coffee, specifically for the amount of dissolved solids in it (after drying).

Example: 1 kg of parchment coffee changes into 0.8 kg of green beans (weight change factor 0.8). And 1 kg of green beans is 25% more valuable than 1 kg of parchment coffee due to the weight loss in processing.
 * Weight change factor: the difference in weight, when you keep the value constant (that is, you compare the weight of one lot of coffee at two stages of processing).
 * Value change factor: the difference in value, when you keep the weight constant (that is, you compare the value of one kilogram of coffee at two stages of processing). This only accounts for the value change due to the weight change (not due to additional value changes due to the labor input into the processing). For this reason, the value change factor is always the inverse of the weight change factor.
