Answer:
luxury crop
Step-by-step explanation:
The coffee, or rather the coffee beans, are crop that can be considered as a luxury crop. The reason why it can be considered as luxury crop is that it is not a crop that is needed for food, or satisfying the basic needs of the humans.
The coffee, instead, is used for other purposes. The people use it as for making a drink which can be considered as socializing drink, drink for keeping up awake, for concentration, or just for joy. This simply puts the coffee in a category of crop that is used for luxury, not for any sustainability need.
In the past, though by the same definition even in modern times, the coffee beans can be considered as cash crops.
