FWK's do not produce the juice, it's copacked for them by another company. They would need to find someone with similar processing capabilities over there.
I wonder if the ability to recognize kit taste is something similar to tasting soap in cilantro. Maybe there's an olfactory receptor gene that makes some people recognize a taste difference in kit wine. For the record, I've never experienced kit taste myself, although I do taste soapy cilantro.
