Winemaker Notes
Whether it’s playful and fun or savory and serious, most rosé today is not your grandmother’s White Zinfandel, though that category remains strong. Pink wine has recently become quite trendy, and this time around it’s commonly quite dry. Since the pigment in red wines comes from keeping fermenting juice in contact with the grape skins for an extended period, it follows that a pink wine can be made using just a brief period of skin contact—usually just a couple of days. The resulting color depends on grape variety and winemaking style, ranging from pale salmon to deep magenta.
As one of Napa’s coolest sub-appellations, the area begs for diversity among its vineyards. Merlot and Chardonnay firmly compete with Cabernet Sauvignon for a place here. Some of Napa’s best Zinfandels also come from the Oak Knoll District.
Situated far in Napa’s southern end, Oak Knoll receives a strong cooling influence from both the San Pablo Bay and the Pacific Coast’s evening fog and breezes. Summer days are warm but on average ten degrees cooler than in St. Helena farther north up the valley; summer nights are chilly. A long growing season promotes for leisurely ripening of grape berries, resulting in an impressive balance of sugars, phenols and acidity.
Notable producers include Trefethen, one of the appellation’s oldest wineries, Robert Biale, legendary Zinfandel producer and Lewis Cellars, a family-run, hands-on establishment.
