I'm always being asked about second labels from higher-end wineries. The logic, obviously, is that a secondary offering form a top-notch winery will likely be a good value. I suppose this is really an open issue as there's no guarantee of QPR except maybe when the higher-end winery openly markets the second label (you'd think they'd have a larger stake in the quality relationship when they do). But the weight of logic is still that these should be good finds.
Opus One has Overture but they don't sell it outside the winery. Oregon's Domaine Drouhin has a second label called Cloudline. But it seems like not all second labels are openly marketed. I found that Napa's Signorello is the grower and winemaker for a terrific Cab called Edge, but has no marketing connection to that wine. Caymus used to have Liberty School,and now has taken their name off Conundrum.
Is there a source out there that summarizes second labels? It would seem to be a great subject for a wine site or blog. Even better........ is their a legitimate source for info on wines that are made from fruit or juice normally used by high-end wineries, but are sold as excess?? I understand that this is probably not something the original winery wants made public, but is there an intelligience network out there on this?
