Immerse yourself in the rich estate history

The 50-acre property was established in 1904 by Frank F. Jantzen, a local Mennonite minister and teacher. The rolling hills on Paso Robles' West Side was the perfect home for raising Jantzen's large family. For years they farmed grain, pears, plums, prunes, apricots, apples, nuts, and tended to the family horses and cows. It wasn't until 1997 that our vines were planted in what we now call paradise on Earth.


HammerSky Vineyards


Early one morning in 2007, Doug drove north from his home in Newport Beach to Paso Robles to look at several properties he had in mind to fulfill his dream of owning a vineyard. He stopped at the first property on his list and parked outside the closed gate. When the current owner eventually he came out to get his mail, he found Doug asleep in his car on the opposite side of the gate and asked, "what are you doing parked in my driveway?" Doug responded, "Well, I'm interested in buying your property." After a long friendly discussion, they shook hands and struck a deal right there at the mailbox.

Doug named the estate HammerSky Vineyards after his two sons, Hamilton and Skyler – nicknamed Hammer and Sky. 


Truly a unique and picturesque property, Doug tastefully enhanced the historic site to be a working winery and inn that he enjoys sharing with others. 

The restored farmhouse inn boasts casual elegance. Built by Frank F. Jantzen for his family in 1904, the gleaming white house embraces its history. Despite the home’s age, its crisp black shutters, second floor balcony, cropped boxwood hedge, and refurbished interior reveal a contemporary aesthetic. The original windows incorporate views of a 300-year-old valley oak tree, affectionately known as Uncle Dan.

The HammerSky estate is graced with several beautiful, native oak and cypress trees – so captivating, that the builders of Hearst Castle requested some of the trees be moved by horse and buggy decades ago to the majestic Hearst Castle and planted next to the Neptune Pool, where they found a new home amid the vast property.

Adjacent to the refurbished, century-old farmhouse stands a stately New England-style white barn that Doug erected for private special occasions


Doug’s eclectic sense of style is especially evident in the tasting room, which stands at the edge of a park-like lawn dotted with large oak trees and picnic tables. The clean lines and smooth, steel-troweled walls of the snow-white structure creates a bold impact amid the rural setting.


The building is surrounded by a rock wall constucted of limestone rock and boulders pulled from the very vineyard that encompasses the tasting room. Completed in 2011, the tasting room facility is just under 1,000 square feet and allows a relaxing, airy space for wine tasting, as well as a barrel room splashed with red and black accents. Tall windows and glass doors emit natural light, while allowing sweeping views of the rolling sea of vines that border the lawn and café-style seating on the patio. It has been referred to as the best picnic location in Paso Robles wine country.

HammerSky has graced many magazines such as Vogue Magazine, Los Angeles Times, 805 living, C Magazine and Pottery Barn, to name a few. HammerSky is becoming well known for the fine hand crafted wines as well as an upscale venue for intimate special occasions.
