Fenestra Winery was established by the Replogle family on the
historic Ruby Hill property and in 1980 occupied the century-old George True Winery building on Vallecitos Road. The old building had been badly neglected,and the Replogles hauled away tons of trash. Now part of the Ruby Hill development, (the Replogles lease the building and surrounding grounds) which includes a Jack Nicklaus designed course, homes and 900 acres of vineyards, the winery building has been refurbished and vineyards have been planted around the winery. The winery specializes in classically balanced, award-winning wines from primarily Livermore Valley grapes. Livermore Valley's first boutique winery, Fenestra Winery is celebrating 34 years of fine wines.

The Denner Winery was completed in time for the 2005 harvest. Ron and John believe that great architecture blends with the environment. Denner Winery, therefore is designed to fit into the rolling hills and is complementary to the geography and culture of the Central Coast and the wines they produce.

tephen and Jamie had a dream of owning their own vineyard someday. Their idea was to buy 5 to 10 acres in the Napa Valley and establish a vineyard. They created a five year plan to save the money they would need. Meanwhile Napa land prices skyrocketed from $35,000/ acre to well over a million dollars an acre. In the spring of 2000 their search lead them to the historic Amador County.While continuing to work full time jobs, they traveled to their ranch in Amador each weekend. Five wells were dug to find the water they would need to supply the vineyardsIn 2004, they had their first crush as a bonded winery. 2006 saw the first crop from their estate vineyards. They expect to grow the winery production to around 2,000 cases annually, which they only sell in the tasting room and through their web site.They are now open with nine wines: Sauvignon Blanc, Viognier, Barbera, Mourvedre, Zinfandel, Syrah, ZinRah, Petite Sirah and a Gnarly Vine Zinfandel Port.
