(SFGate) - GI Partners, a San Francisco private equity firm, has agreed to buy a majority share of Napa’s Far Niente Wine Estates, which includes the wineries Far Niente, Dolce, Nickel & Nickel, EnRoute and Bella Union. Far Niente’s current owners Beth Nickel, Erik Nickel, Dirk Hampson and Larry Maguire remain shareholders. The price of the deal and percentage of ownership was not disclosed.

It must be buyout season. The news of the Far Niente investment comes on the heels of two big Bay Area deals announced yesterday: Jackson Family Wines is purchasing Healdsburg’s Copain Winery, and Cowgirl Creamery in Point Reyes will merge with Swiss dairy company Emmi.

First established in 1885, the Far Niente winery was left abandoned after Prohibition took effect. Gil and Beth Nickel revived the property in 1979 and over the decades established one of Napa Valley’s most recognizable Cabernet Sauvignon and Chardonnay brands. The Sauternes-style sweet wine Dolce was first produced in 1989; 1997 saw the first vintage of Nickel & Nickel, a label focused on single-vineyard Cabernet. EnRoute, a Pinot Noir and Chardonnay project, launched in 2007, and another Cabernet label, Bella Union, began in 2012.

In total, the five wineries produce about 75,000 cases of wine annually.
