I dont believe ingredients will provide anybody with a good picture as to what extent the wine has been manipulated. Just like organic farming cannot guarantee that different practices are being done after the fruit has been harvested in the winery. The fact is, that as discussed, some technologies developed to alter the winemaking process work to the advantage of the wine itself (like temperature control) and others to alter the perception of what the terroir or the wine are trying to express (microoxygenation).
California is an extremely financial driven wine growing region. There are those trying to mirror what was done in the past, for the love of wine; and there are those trying to capitalize at the expense of that fame.
The Elephants in the Cellar are created sadly for people who see wine more like a social status, and not an expression of place and time.
