Winemaker Notes
Grenache thrives in any warm, Mediterranean climate where ample sunlight allows its clusters to achieve full phenolic ripeness. While Grenache's birthplace is Spain (there called Garnacha), today it is more recognized as the key player in the red blends of the Southern Rhône, namely Châteauneuf-du-Pape, Côtes du Rhône and its villages. Somm Secret—The Italian island of Sardinia produces bold, rustic, single varietal Grenache (there called Cannonau). California, Washington and Australia have achieved found success with Grenache, both flying solo and in blends.
Nearly a northern extension of Napa Valley, Alexander Valley starts just north of the small, Knights Valley, and is just a few minutes drive from the Napa town of Calistoga. It is Sonoma County’s hottest AVA. But the Russian River, which runs through the valley, creates cooler pockets and its soft, alluvial soil is ideal for grape growing, especially Cabernet Sauvignon. In fact, some believe that Alexander Valley Cabernets truly rival the best from Napa Valley and many of the heavy-hitter producers have largely invested here.
In addition to Cabernet Sauvignon, which makes up over 50% of plantings, Merlot and old vine Zinfandel thrive here. Ample, fleshy Chardonnay and Sauvignon Blanc dominate white wine production. Some old-vine plantings of Grenache have also been discovered and more recent experiments with Sangiovese and Barbera show great promise.
