The McGrail's invite you to taste their small lot wines, picnic, explore the vineyard, and enjoy the panoramic views from their hilltop tasting room. 

Jim and Ginger McGrail, planted the Cabernet Sauvignon vineyard in 1999 and originally sold all fruit to Steven Kent Winery. In 2003, the McGrail family along with the help of Rhonda Wood made a barrel to enjoy with friends and family. The following vintage one barrel turned into five, and by 2005 the McGrail's were starting production on 1,000 cases of wine.

By the end of 2005, the McGrail's decided they were going to go into the production side of the wine business and decided to start planning for a winery. After almost three years, Jim, Ginger, and their daughter Heather, finished the estate tasting room and winery on the property of the vineyard.

April 2008, marked the Grand Opening of the tasting room and winery.
