Emerging details of cacáo on Taiwan indicate a generally open door policy during the 1920s & 30s welcomed introductions from, it is thought, Indonesia & Malaysia. Later, circa the 1970s, material came from Brazil, presumably of the Amelonado strain.
With genetic testing on the horizon, more specificity will reveal the identity of an intensely hybridized & diversified array of cacáo types, as well their interrelationships & provenance.
