Did they state why they crossed it with *liberica*? That species is
generally known for its extremely high caffeine content (in some cases
exceeding 8% !!). Typically arabica X3 = robusta X3 = liberica for
caffeine content.
A lot of the Andean arabicas are well below 1% caffeine, depending on
the strain grown. There may be arabica strains out there that are
virtually caffeine free already but no one has prospected them. They
probably get mixed in with higher caffeine stuff and disappear into
commerce unnoticed.
Most of the organic coffees out of the Andes are low-caffeine arabicas
and quite a good brew if roasted right.
