Niebaum Coppola's Blue Label Merlot is wonderful! I have served it to people who swear they hate merlot and they have loved it. It has many cabernet qualities.
I understand the estate's name just was changed from Niebaum Coppola to Rubicon Estates. Francis Ford Coppola, the director, owns this winery.
Actually, every red I've tried from his offerings has been good. I just stay away from his whites. He doesn't do those well, IMHO.
Goofy, what year Silver Oak did you serve? Could that have made a difference in the blind tasting? i.e. it was too young, or aged more than the Monte Antico? That's very interesting that your eonophile friends liked the $10 bottle better. I'll have to pick up one, myself, to taste.
