You’re breaking my heart, Kevin. Abdicating the romance and mystery of wine in the face of cold, hard commerciality seems, well, cynical. But you’re right, there is some reasonable manipulation (see my teaching analogy, above) and then a line beyond which the wine’s true nature is compromised. I would say that playing fast and loose with the organoleptic profile, i.e. with acid, concentrate, enzymes, and tannin, is going too far. Any other opinions?
