I may have to rethink the Pinotage. It appears it is susceptible to VA plus you don't know how it was processed.

To me, Pinotage is reminiscent of one of its parents, viz., Cinsault. If you are considering making a Pinotage, you should definitely try a commercial bottle of it or of Cinsault some time. In addition to the descriptors in your nice Wine Folly article, I would add "gamey." It is an unusual taste in a wine. I like it, but it is.... different.
