Winemaker Notes
Apart from the classics, we find many regional gems of different styles.
Late harvest wines are probably the easiest to understand. Grapes are picked so late that the sugars build up and residual sugar remains after the fermentation process. Ice wine, a style founded in Germany and there referred to as eiswein, is an extreme late harvest wine, produced from grapes frozen on the vine, and pressed while still frozen, resulting in a higher concentration of sugar. It is becoming a specialty of Canada as well, where it takes on the English name of ice wine.
Vin Santo, literally “holy wine,” is a Tuscan sweet wine made from drying the local white grapes Trebbiano Toscano and Malvasia in the winery and not pressing until somewhere between November and March.
Rutherglen is an historic wine region in northeast Victoria, Australia, famous for its fortified Topaque and Muscat with complex tawny characteristics.
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.
