The Rhône Ranger

When Randall Grahm founded Bonny Doon Vineyard 35 years ago, he discovered that his land on California's Central Coast produced great Rhône varieties, including his marquee Rhône-style wine, Le Cigare Volant. But he's now set his sights even higher and embarked on what may just be the most ambitious viticulture project of all time, breeding 10,000 new grape varietals on his San Juan Batista property, in hopes of developing a unique California Grand Cru.
