Play winemaker for a morning and craft your own Bordeaux-style blend from Cabernet Sauvignon, Cabernet Franc, and Merlot. You'll stroll through Cornerstone Gardens to soak up Sonoma's winemaking history, then experiment with proportions using all five senses until your custom creation is just right. Bottle it up with a hand-applied label and cork to take home, plus locally sourced cheeses to nibble while you blend.
