While consumption of coffee was traditionally low in much of Asia, former European colonies brought not only a taste for coffee but also a desire to grow it.
Lower-grown Robusta varieties of coffee were more suitable for a larger amount of land than Arabica types. Arabica needs a cooler mountain climate with less humidity. Nonetheless there was Arabica cultivation in many nations, even though it was a small fraction of the total mass of land.
With a greater interest in cafe culture, Asian nations have focused on coffee growing as well. Often this is to sell to the local market. This exciting focus on locally produced coffee (something impossible in the coffee consuming nations of the global north) opens up a range of new possibilities in both coffee growing and quality!
