Remember Jan from the Brady Bunch? She was the less pretty, less popular younger sister of the sparkling Marcia Brady. While she only melted down once during her four seasons of second class status, (recall the classic “Marcia Marcia Marcia!” episode of season 3), her insecurities were a constant. We Californians have another, perhaps lesser-known rivalry, right in our front yard – that of the wine producing regions of Sonoma and Napa counties. (Yes, the Napa wine-as-buxom-blonde analogy has been done and overdone, but bear with me here). When it comes to wine production, Napa has historically been like Marcia – sexy and popular. Sonoma has been more like Jan – smart and pretty, but a little insecure. Fortunately, this may be changing.
