How can we define a second label–Opus One is Mondavis second label or Rothschilds second label and Pavillon Rouge is Margauxs second label, right?
You’re right on the Margaux-Pavillon Rouge connection. But Opus is not a second label for Mondavi–it’s a joint venture between Robert Mondavi Winery and Chateau Mouton-Rothschild. Usually a second label is a winery’s lower-priced, lesser-quality wine sold under a different brand name than the primary label. But there are no hard-and-fast rules, as some wineriers have so-called parallel brands–wines that are not second labels. Example: Joseph Phelps Vineyards and Phelps Vin du Mistral.
