Winemaker Notes
Owned and operated by Irit and Ernie Weir, the winery was founded in 1979, and the first commercially released vintage was harvested in 1980. In the ensuing years, Hagafen has grown from a small partnership producing wine with grapes from Winery Lake Vineyard, then owned by Rene DiRosa, to a well-established wine company whose wines are distributed throughout North America and overseas. Since 1980 Hagafen wines have been served on numerous occasions at the White House to visiting foreign dignitaries. Ernie’s daily involvement in the two sides of wine production, grape growing and winemaking, ensures the superb quality of the wines.
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.
One of the most popular and versatile white wine grapes, Chardonnay offers a wide range of flavors and styles depending on where it is grown and how it is made. While it tends to flourish in most environments, Chardonnay from its Burgundian homeland produces some of the most remarkable and longest lived examples. California produces both oaky, buttery styles and leaner, European-inspired wines. Somm Secret—The Burgundian subregion of Chablis, while typically using older oak barrels, produces a bright style similar to the unoaked style. Anyone who doesn't like oaky Chardonnay would likely enjoy Chablis.
