Hammersky Vineyards produces incredible Bordeaux-centric estate wines with a focus on sustainable farming practices, and opportunities to explore them all from their tasting room on Vineyard Drive.

The tasting room at HammerSky is one of the most beautiful in the county with huge windows that offer views of the vineyards, and a stunning outdoor patio where guests can explore the latest varietals while enjoying the perfect weather found in Paso Robles’s wine country.  

Hours may change depending on the season, so please check their website for current hours and availability. 

Special Events

HammerSky also hosts a variety of special events that celebrate both the wines they create and the process to do so throughout the year. Many are open to the public, but some events may be exclusive to the wine club so make sure to check their website for details beforehand. 

Weddings & Special Occasions

HammerSky’s gorgeous location in Paso Robles provides the perfect backdrop for any special occasion from weddings to family gatherings, corporate retreats, and photo shoots. 

In addition to the Tasting Room, the property includes the restored farmhouse built by the Jantzen family in 1904, a traditional New Hampshire barn, grassy lawn areas shaded by ancient oak trees, and 50 acres of vineyards.

The Farmhouse at HammerSky is the restored family home of Jantzens, the original owners of the estate. Original built in 1904, Douglas Hauck careful and intentionally restored the Farmhouse to its original beauty when he bought the property in 2007, but this time with all the modern amenities included.

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

Visit HammerSky’s website for more information on renting the Farmhouse. 



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.”


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.  

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 Proprietor Douglas 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”.

HammerSky Vineyards

The Adelaida District is one of the eleven sub-districts that make up the larger Paso Robles American Viticulture Area, and home to some of the oldest grapes in Paso Robles’ Wine Country.

Although San Luis Obispo County has a long history of grape growing (and today Paso Robles is synonymous with wine country), commercial wineries were not introduced to the area until 1964.

That year Dr. Stanley Hoffman purchased 1,200 acres in the heart of what is now the Adelaida District, and with the help of influential winemaker André Tchelistcheff, Hoffman planted the vineyards that became Hoffman Mountain Ranch Winery, the first commercial winery in all of Paso Robles’s AVA.

Today the distinct terroir profiles (or growing conditions) of the eleven districts contribute to the production of over 40 varietals (the vast majority crafted from Cabernet Sauvignon, Roussanne, Zinfandel, Viognier, Merlot, and Syrah), and home to over 200 wineries for locals and tourists to enjoy and explore.
