Edna Valley & Paragon Vineyard

The Niven Family
Pioneers of the Edna Valley AVA
San Luis Obispo, CA

Jack Niven pioneered wine grape planting in the Edna Valley with Paragon Vineyard in 1973. Our family has been continually growing Sauvignon Blanc and other cool climate white varietals since Jack planted those first vines over 40 years ago. Recognizing the unique and tremendous potential of the region, he championed the process of petitioning for it to become an AVA. The application was approved, and the Edna Valley was officially created in 1982.

The coolest growing region in all of California, as cited in a study by the University of Southern Oregon, the Edna Valley is a mere 5.4 miles from the Pacific Ocean. The ocean's influence creates our unusually long growing season, and allows the fruit in our vineyards to ripen to their full flavor while preserving Tangent’s trademark lively acidity. In short, the Edna Valley is one the best places on earth for growing pure, vibrant white varietals.

We are proud to say that we have farmed in a sustainable fashion since the beginning. Our Paragon Vineyard was one of the first Central Coast vineyards to become SIP Certified Sustainable; we participated in the pilot program in 2008.


Tangent winery stands on a knoll in the Edna Valley, surrounded by the estate Paragon Vineyard. Built in 1999, it is both high-tech and unusually dramatic.It is stocked with innovative equipment including a state-of-the-art fruit delivery system, and an army of different size stainless steel tanks and stainless steel barrels to house our unoaked Tangent wines.

Each of the cellar bays is lined with huge windows that allow sunlight into what is traditionally a dark and damp environment. In addition to being aesthetically pleasing, the natural light actually helps keep the winery clean.

SIP Certification

Our estate Paragon Vineyard was one of the first Central Coast vineyards to become SIP Certified—the Niven Family participated in the SIP pilot program in 2008. It’s currently one of the largest SIP Certified vineyards in the state of California. Historically, we have always farmed in a careful and responsible manner that takes into account all facets of the world around us, and would continue to do so whether or not this certification program was developed.

To be certified, we were presented with a robust and comprehensive set of standards, then audited by an independent, third-party inspector. The Certification was then granted by an independent advisory board.

What is SIP?

Certification is a rigorous sustainable vineyard certification with strict, non-negotiable requirements. The program is dedicated to the three P’s of Sustainability—People, Planet, and Prosperity—and ensures that both natural and human resources are protected. They are committed to standards based on science and expert input, independent verification, transparency, and absence of conflict of interest.

They pride themselves on the program’s rigor and integrity, which have earned SIP the reputation as being the gold standard for sustainable certification.

Owl Boxes

We provide multiple owl boxes throughout our vineyard to encourage nesting for predatory birds, which helps maintain rodent populations.


Our goats help keep our natural vegetation areas from becoming too overgrown, which provides protection for our waterways and helps maintain wildlife habitats.

Jack Rabbits

There are numerous jack rabbits living in our vineyard, which is an indication of biodiversity and a healthy ecosystem.
