The Stag's Leap wine was much younger and a much darker color. The nose was less evolved but still full of dark cherries, a few blueberries, a tiny bit of vegetable that I found appealing and clean whiff of dry earth. Full flavored with the cherries dominating. There was a richer mouth feel to this wine, and the richer feeling stood up a little better to the beef than the Mondavi. Good acid and a nice level of tannin at the finish made this wine a winner.
Very difficult to choose a favorite here as both wines offered their best efforts and were quite enjoyable. I loved them both.
Prices unknown but the Mondavi was 13.3% alcohol and the Stag's Leap was 14%.
