ONX Wines

ONX Wines Certified Sustainable Winery and Vineyards. Tasting room located in Tin City, Paso Robles.

At ONX (pronounced Onyx) Wines, we have established a reputation for crafting blends that push the envelope of tradition while being dedicated stewards of our land. Earning certifications for our estates with the California Sustainable Winegrowing Alliance, we are focused on making acclaimed wines not just for today, but for generations to come. In 2004, lifelong entrepreneurs Steve and Brenda Ols

on began searching for land in the Paso Robles AVA. Upon encountering an idyllic property in the Templeton Gap, they immediately recognized the potential of the land and established what would be the beginning of the 127-acre ONX Estate Vineyard. In the time following, ONX would find a permanent winemaking home and tasting room in Tin City, as well as acquire their Kiler Canyon Vineyard in Willow Creek. To learn more about ONX Wines, book a vineyard tour at the ONX Estate or a tasting at the Tin City Tasting Room and Winery.

Veraison is moving fast across the ONX Estate 🍇

After a stretch of near-100° days, temperatures have dropped, and the vines are back to focused ripening. Green berries are turning reddish-purple, block by block.

While much of the Central Coast is tracking toward a very early harvest, our Templeton Gap site runs on its own clock. The marine breeze that rolls through at night cools the vineyard, allowing the fruit to ripen at a slower, more measured pace. For ONX, that likely means a few more weeks before we begin picking reds, distinct from the rest of Paso.

And this year marks another milestone for the vineyard: 2026 is our third year of organic farming, and we’re officially beginning the application process for CCOF Organic certification for the ONX Estate Vineyard. 🌱

🍇 Meet our 2026 harvest interns!

We’re excited to have Kalib Khan and Sarah Walsh joining us for harvest!

Kalib is joining our cellar team for his first harvest with us and second overall. A San Luis Obispo County local, he just returned from an eight-month backpacking adventure through Vietnam, Japan, Thailand, Cambodia, and the Philippines. 🌏

Sarah is joining us as a viticulture intern for her first-ever harvest. Originally from Thousand Oaks, she’s a climber, camper, and backpacker when she’s not in the vineyard.

Welcome, Kalib and Sarah! We’re so happy to have you both here. Let’s get this harvest started! 🍷

Tucked into the hills of the Willow Creek District, the Kiler Canyon Ranch House treats you to some of the most gorgeous views in wine country.

Right on the property, you’ll find a hot tub, fire pit, and barbecue to enjoy at your leisure — and when you’re ready to head into town, downtown Paso Robles is just a quick 10-minute drive away.

We’ll also host you for a complimentary wine tour or tasting during your visit, and the vineyards are yours to explore whenever you like.

How do we know when the grapes are getting close to harvest? 🍇

Brix is one of the measurements we use to track ripeness, giving us a look at how sugar levels are developing in the grapes. Vineyard Manager Tucker Robertson walks us through how we check Brix as harvest approaches at the ONX Estate.

8- and 11-year anniversaries! 🍇🎉

Two members of our winemaking team just hit major milestones. Lauren Lange, our Associate Winemaker, is celebrating 8 years with ONX. She’s been instrumental in crafting our wines and leads winemaking for our custom crush clients. Drew Nenow is celebrating 11 years, and was recently promoted to Director of Winemaking & Vineyards, deepening the connection between vineyard and cellar.

Lauren and Drew, thank you for all of your incredible contributions over the years, and here’s to many more!

And so it begins... 🍇 Veraison has started on the ONX Estate in Block 109 Tempranillo. This is the stage where fruit starts ripening as sugars rise, acids decline, and grape color deepens. Harvest is on its way!
