Cameron Hughes 2012 Cabernet Sauvignon Lot 555

By all reports this is one of the best CH wines and drinking nicely at this time. At the time of its release, Cameron said this Cab was sourced from a fantastic estate in Rutherford “deeply rooted in classical traditions and family winemaking heritage. It’s vineyards are certainly amongst Napa’s finest, and definitely in the discussion for the top ten.”
Our local wine tasting group is going to do blind tasting of Cabernet Sauvignons later this month. Fortunately I have sufficient bottles of this 555 to share. Does anyone have an idea of the source of this Rutherford CS? All opinions are welcome! Thank you.
