Jose, I think you'll find that it is prevalent, just not neccessarily
noted on label. I checked what California wines labeled as Cabernet
Sauvignon I had. Only 1 seems to be 100% CS (BV GdlT):
Barnett Spring Mountain: CF & Merlot
Montelena Calistoga: CF & Merlot
Pine Ridge Stagsd Leap: Merlot, Petit Verdot, and Malbec
St Clement: CF
St Jean: 10% Cab Franc
Sebastiani: CF,Merlot, and Zin!
Worthy (Axios): CF, Merlot, PV

I can't find reference one way or the other re Karl Lawrence, anyone
know?
Someone more knowledgable about CA might correct me, but my impression
is that most wines labeled CS and Merlot probably have a bit of other
grapes mixed in. Pinot Noir is usually 100%, and varietally labeled
Zins and Syrahs vary.
There's nothing wrong with blending, almost all of the greatest
Bordeaux are blends
