Paso Robles Wine: California's Most Exciting and Underrated Region

For most of its history, Paso Robles has been California's afterthought — a warm, sprawling wine region on the Central Coast that produced decent Zinfandel and Cabernet at prices that undercut Napa without threatening its prestige. Critics acknowledged it politely. Collectors largely ignored it.

That era is over.

Over the past fifteen years, Paso Robles has undergone a transformation that is one of the most compelling stories in American wine. A new generation of producers — many of them trained in Burgundy, the Rhône Valley, and Napa — has discovered that the region's extreme diversity of soils, elevations, and microclimates can produce wines of genuine complexity and world-class quality. The prices have not caught up yet. That will change.

Paso Robles sits roughly halfway between Los Angeles and San Francisco, in the Santa Lucia mountain range of California's Central Coast. The region is large — over 600,000 acres — and its geography is more varied than almost any other California wine region.

The key variable is the Templeton Gap, a break in the Santa Lucia Range that allows cool Pacific air to pour into the valley each afternoon, dropping temperatures by as much as 50°F between the heat of the day and the cool of the night. This dramatic diurnal temperature swing is the defining feature of Paso Robles viticulture — it allows grapes to ripen fully in the warm days while preserving the acidity and aromatics that give the wines their freshness.

But the Templeton Gap does not reach everywhere equally. The western side of the region, closest to the coast, receives the most cooling influence and produces wines of greater elegance and restraint. The eastern side, further from the ocean, is warmer and drier, producing wines of greater concentration and power. Understanding this east-west divide is the key to understanding Paso Robles.

Paso Robles was formally divided into eleven sub-AVAs in 2014, a recognition of the region's extraordinary diversity. The most important for wine quality are:

The coolest and most prestigious of the sub-AVAs, the Adelaida District sits in the western hills closest to the coast. The soils here are calcareous — high in limestone and chalk — which is unusual for California and produces wines of distinctive minerality and freshness. This is where the region's most ambitious producers have planted, and where the most age-worthy wines are made. Tablas Creek, Booker Vineyard, and Saxum Vineyards all have significant holdings here.

Named for the coastal wind gap that defines the region's climate, the Templeton Gap District benefits from the most dramatic diurnal temperature swings in Paso Robles. The soils are a mix of sandy loam and clay, and the wines tend to combine the concentration of the warmer east with the freshness of the cooler west. This is the sweet spot of the region for many producers.

A small, high-elevation district in the western hills, Willow Creek is one of the coolest parts of Paso Robles and produces wines of unusual elegance and restraint. Calcareous Vineyard is the benchmark producer here.

The warmest and most productive of the sub-AVAs, the Estrella District on the eastern side of the region produces wines of considerable power and concentration. This is where much of Paso's bulk production comes from, but the best producers here make wines of genuine quality at accessible prices.

Paso Robles Cabernet is the region's calling card for most consumers, and the best examples are genuinely impressive — dark-fruited, structured, and built for aging, with a warmth and generosity that distinguishes them from their Napa counterparts. The key is finding producers who work in the cooler western districts, where the acidity and freshness to balance the fruit are more reliably present.

The most exciting wines in Paso Robles are not the Cabernets. They are the Rhône varieties — Syrah, Grenache, Mourvèdre, Roussanne, Viognier, and their blends — that have found a natural home in the region's warm days and cool nights.

Tablas Creek Vineyard, a partnership between the Perrin family of Château Beaucastel and importer Robert Haas, was the pioneer. They imported Rhône cuttings directly from Beaucastel in the 1990s and have spent three decades proving that Paso Robles is one of the world's great Rhône variety regions. Their Esprit de Tablas (a Mourvèdre-Grenache-Syrah blend) is one of the finest American wines made from these varieties.

Saxum Vineyards, under winemaker Justin Smith, has taken the Rhône tradition to its logical extreme, producing single-vineyard Syrah and Grenache-based blends of extraordinary concentration and complexity. The James Berry Vineyard bottling has received multiple 100-point scores and is one of the most sought-after wines in California.

Paso Robles has a long history with Zinfandel, and the best examples here are among the finest in California — ripe, spicy, and full of character, with a warmth that suits the grape's exuberant personality. For more on Zinfandel as a variety, see our American Zinfandel Guide.

Tablas Creek Vineyard — The Rhône pioneer. Their estate-grown blends and single-variety wines are benchmarks for what Paso Robles can achieve with these varieties. The Esprit de Tablas is essential.

Saxum Vineyards — Justin Smith's single-vineyard Rhône blends are among the most sought-after wines in California. Allocations are extremely limited; get on the mailing list.

Booker Vineyard — Eric Jensen is making some of the most concentrated and compelling Syrah and Grenache in the region from his Adelaida District estate. The Fracture and My Favorite Neighbor bottlings are excellent entry points.

Calcareous Vineyard — Willow Creek District wines of unusual elegance and restraint, with a focus on Cabernet Sauvignon and Rhône varieties. One of the best values in the region.

L'Aventure Winery — Stephan Asseo, a Frenchman who left Bordeaux for Paso Robles in the late 1990s, is making some of the most complex and age-worthy wines in the region. The Optimus blend is a benchmark.

Epoch Estate Wines — A newer producer making wines of extraordinary precision from high-elevation Templeton Gap vineyards. The Paderewski Vineyard Syrah is one of the region's finest.

One of Paso Robles' great virtues is value. The region's best wines are significantly less expensive than comparable quality from Napa, and the entry-level offerings from top producers are among the best values in California wine. If you are looking to explore serious California wine without Napa prices, Paso Robles is where you start.

Paso Robles is California's most exciting wine story right now. The combination of extraordinary terroir diversity, a new generation of ambitious producers, and prices that have not yet caught up with quality makes it the best hunting ground for serious American wine at every price point.

The Rhône varieties are the headline, but the Cabernets, Zinfandels, and white wines are all worth exploring. This is a region in full creative bloom, and the best is still ahead.
