In Depth

“Heaven?” you ask. Close. You're in Wine Country. And while the views in Napa, Sonoma, Lake and Mendocino counties are enough to make you dizzy with delight, the extravagantly verdant countryside isn't for shutterbugs alone.

There's a business growing here, and a fruitful one at that. Every year some 400 wineries produce nearly 2 billion bottles of wine thanks to an ideal, varied climate—balmy days with cool mornings and evenings interspersed with floating blankets of Pacific fog. Add relatively cheap labor and mineral-rich soil, and the bottled result has caught the eyes, noses and palates of wine lovers around the globe.

With all its many fun things to do—hot air ballooning, shopping in elite boutiques, hiking, bicycling, touring historical sites, kayaking, gorging on sinfully delicious gourmet food, horseback riding, relaxing with a massage or sinking into a mud or mineral bath—it still comes as no surprise that most visitors are here for one thing: fermented grape juice. Yes, the sweet nectar of the gods.
