Coffee growing in Taiwan is slowly increasing though total volumes are minuscule by comparison with formal coffee regions. Still, there is an upsurge in coffee growing here, and much of the mountain tea growing areas may be suitable to growing coffee, too!
But overall coffee volumes are minuscule compared to even third tier coffee producing countries. And if you buy ‘Taiwan coffee’, it’s most likely mixed with beans from Indonesia and/or Vietnam so it’s hardly pure!
I was surprised to find farmers attempting to grow coffee here despite the challenges. There’s even one who only lives about 20 kms from my home! And I’m told that my Brother in Law has tried to grow some in the mountains.
Who knows, eh?
