The Olson Family has been committed to farming and real estate for over a century. With ONX Estate Winery, the family continues its farming activities much the same way their Scandinavian grandparents did more than 100 years ago. The Olson family is fully focused on continuing the tradition of making world renowned wines for generations to come.
In 2004, the Olson’s purchased property in Templeton that eventually became ONX Estate Vineyard. While preparing the vineyard land for planting, they discovered limestone and Calcite Onyx on the property, paving the way for the future name of the winery. The original prototype vineyard included a medley of Tempranillo, Grenache, Syrah, Mouvedre, Petit Sirah, and Zinfandel. With the addition of winemaker Brian Brown, who introduced micro-farming, more acres were planted. By 2008 the first wines were vinted in a mad crush, giving rise to the name of the original blend. Three other blends rounded out the “Core Four” and “Mad Crush”, Praetorian”, “Brash”, and “Reckoning” are still in production today.
