HammerSky Vineyards

HammerSky Vineyards is an estate winery located in Paso Robles’ Adelaida Wine Region, and produces incredible Bordeaux-centric estate wines with a focus on sustainable farming practices. 

We had the pleasure of visiting HammerSky for Industry Night in early 2019 and got to learn all about what makes their estate, vineyards, and varietals so special.

HammerSky Vineyard is located on Vineyard Drive in Paso Robles, deep within the Paso Robles American Viticulture Area (AVA).  Approximately 20 minutes northwest of Paso Robles (or 20 minutes southwest of Templeton), the 50-acre estate is nestled against iconic rolling hills and offers stunning views of their vineyards and the surrounding landscape from the Farmhouse and Tasting Room.

In 1904, local Mennonite minister and teacher Frank Jantzen purchased a 50-acre plot on Vineyard Drive in Paso Robles, and moved his large family there where they farmed grains, grew stone fruit, nut, and apple trees, and raised livestock for almost 90 years.  In 1997 the first vineyards were planted laying the groundwork for what later became HammerSky Vineyards.  

Ten years later the current owner of the estate went to get the mail and found a stranger asleep in his driveway.  After a curious confrontation, Douglas Hauck sleepily introduced himself and told the owner he was interested in buying the property. 

That chance meeting in 2007 turned into a successful sale of the estate to Hauck, who became the new proprietor of the property and renamed it HammerSky Vineyards after his two sons: Hamilton and Skyler. 


Douglas Hauck is the proprietor of HammerSky Vineyards, and brings a fascinating mix of business, art, and science to the management of the estate. 

Hauck originally obtained a degree in Business from the University of Southern California; continued his education with a degree in Filmmaking from the University of California at Los Angeles; and in 1988 earned his Doctorate in Dental Surgery from the University of the Pacific in San Francisco.  Today Hauck continues to run his successful dental practice, splitting his time between Orange County and Paso Robles. 

Just like some of the varietals at HammerSky, Hauck’s background is a unique blend of art and science, and even he will say “both are total opposites from different origins, but the juxtaposition of the two creates the ying and the yang for the balance of life.”

Terroir Profile

The Paso Robles AVA is comprised of 11 sub-regions, which includes the Adelaida District where HammerSky Vineyard can be found.  Vineyards in this region are best known for their Cabernet Sauvignon varietals, which holds true for many of the wines produced at HammerSky.

However, HammerSky also sits near the the Templeton Gap District, and benefits greatly from the calcareous shale in the soil, natural rainfall, and cooler temperatures that microclimate is know for. 

The soil in the Templeton Gap region most closely resembles the soil found in France’s Bordeaux region, which allows for the vines at HammerSky to grow deeply and develop a balanced minerality not always found in other varietals.

 The resulting wines are Bordeaux-centric, with each bottle handcrafted from the 25 acres of grapes grown directly on the estate.  

Additionally, the vines themselves are over 20 years old and are well established at this point in their lifecycle; the age of the vines combined with the natural properties of the soil and strict farming practices implemented by Hauck allow HammerSky to practice sustainable farming as they “let mother nature rule our vineyard”. 

Although this may result in a smaller yield than other wineries, the practice is purposeful and results in varietals with intense in flavor. As Hauck so lovingly describes it, he is creating “couture wine for the senses”.

The Farmhouse at HammerSky was original built by the Jantzen family when they moved to the estate in 1904.  When Douglas Hauck purchased the property in 2007 he careful and intentionally restored the Farmhouse to its original beauty, but with all the modern amenities included. 

Guests of the Farmhouse have access to three bedrooms, a large sitting area, gourmet kitchen, and beautiful dining room. The estate also offers wifi, satellite television, and a Tesla charging station.  Outside guests can relax on the patio, enjoy a charcoal BBQ, and sit in the jacuzzi with a glass of their favorite HammerSky wine.
