Halter Ranch Becomes the First Paso Robles Winery to Achieve Glyphosate Residue Free Certification by The Detox Project
We’re starting spring strong with some exciting news from the heart of Paso Robles wine country: Halter Ranch has officially become the first Paso Robles winery to earn Glyphosate Residue Free Certification from The Detox Project.
This milestone is an exciting step forward for us, and one we’re incredibly proud of. It reflects our dedication to keeping our bodies and our planet healthy through organic and regenerative farming practices.
What Is Glyphosate & Why Does Certification Matter?
Glyphosate is the most heavily used synthetic herbicide in the world, widely used in conventional agriculture to kill weeds. It’s been linked to potential human health and environmental risks. In 2015, the World Health Organization’s International Agency for Research on Cancer classified glyphosate as “probably carcinogenic to humans.”
Glyphosate Residue Free Certification verifies that products have been tested for glyphosate residues by third-party accredited labs and meet The Detox Project’s rigorous standard of no detectable glyphosate down to parts-per-billion levels.
To earn this certification, our wines underwent:
Independent laboratory testing
Third-party verification
Ongoing retesting to confirm zero detectable glyphosate residues
Glyphosate Residue Free Certified Wines
We submitted more than 30 Halter Ranch wines for testing, all of which passed by a mile. These wines include:
2016 Ancestor
2020 Estate Cabernet Sauvignon
2024 Grenache Blanc
2024 Estate Rosé
2024 Organic Picpoul Blanc
And more!
We hope that gives you extra peace of mind and makes every sip taste even sweeter.
Growing a Better Future With Regenerative Organic Farming
For Halter Ranch, Glyphosate Residue Free Certification is part of long-term commitment to organic winegrowing and regenerative agriculture. It represents the latest achievement in a comprehensive program that extends to our Temecula, CA, and Fredericksburg, TX, locations.
Our Estate’s vineyards are certified organic by the California Certified Organic Farmers (CCOF) and have also earned Regenerative Organic Certification® from the Regenerative Organic Alliance, a holistic standard that focuses on soil health, animal welfare, and social fairness.
We prioritize soil vitality, ecosystem balance, and sustainability through practices like:
Cover cropping to protect and nourish soils
Composting to build long-term fertility
Biodiversity corridors to support beneficial insects and wildlife
Sheep grazing to naturally manage vineyard growth
Water conservation systems
Renewable energy initiatives
Low-impact winery operations
By integrating time-honored viticultural traditions with forward-thinking environmental standards, we’re always striving to set a benchmark for responsible winegrowing on California’s Central Coast.
