Understanding the Difference Between Petite Sirah and Syrah

The Name Game: What's the Connection?

Here's where it gets interesting. Petite Sirah is related to Syrah, but not in the way you might think. Petite Sirah—originally called Durif after the French botanist who discovered it in the 1880s—is actually the offspring of Syrah crossed with an obscure grape called Peloursin. So yes, they share DNA, but they're definitely not the same grape. In some ways, they are as different as Cabernet vs. Mourvèdre grapes.

The "petite" in Petite Sirah doesn't refer to the wine's body (spoiler alert: there's nothing petite about it). Instead, it describes the small, tightly-clustered grapes on the vine. When these grapes made their way to California in the late 1800s, they earned their American name, and the rest is history.

Tasting the Difference

Small grapes, big flavor. While Syrah's clusters grow with graceful spacing, Petite Sirah's tightly-packed 'petite' berries produce some of the most concentrated, full-bodied wine you'll ever taste. Size isn't everything!

Syrah is the sophisticated globetrotter of the two. Known for its deep purple hue, it delivers an elegant punch of dark berries—think blueberries, blackberries, and plums—with intriguing notes of black pepper, smoke, and sometimes even a hint of violets or cured meat. It's a medium to full-bodied wine with structure and complexity that can lean either fruity or earthy depending on where it's grown.

Petite Sirah, on the other hand, is the bold powerhouse that doesn't apologize for taking up space. This wine is famous for its almost opaque, inky color that can literally stain your teeth (a badge of honor for Petite Sirah lovers!). It's bigger, bolder, and packed with plump flavors of blueberry jam, dark chocolate, and blackberry, wrapped in notoriously thick tannins that give it a chewy, full-bodied texture.

Why Paso Robles is Perfect for Both

Here's where things get really exciting for us in Paso Robles. Our region has something special that makes both of these grapes absolutely shine: the most extreme day-to-night temperature swings in North America.

During the growing season, temperatures in Paso can soar past 105°F during the day, then plummet by 40-50°F at night. This dramatic diurnal shift is like magic for wine grapes. The warm days allow the fruit to develop intense, concentrated flavors and achieve full ripeness. Then, when temperatures drop at night, the vines essentially "go to sleep," preserving the grapes' natural acidity and preventing them from becoming flabby or overripe.

The secret to Paso Robles magic? A 50-degree temperature swing between day and night. Our vines bask in 105°F heat, then rest under cool 55°F nights—creating wines with both power and perfect balance

What makes Paso even more special is our incredible soil diversity—we have over 30 different soil types, including abundant calcareous (limestone-rich) soils that are rare in California. These alkaline soils help vines retain acidity while developing concentrated flavors, which is crucial in a warm climate.

For Syrah, this means grapes that ripen slowly and develop deep complexity while maintaining that crucial balance between sugar and acid. Paso Robles Syrah tends to be full-bodied with lush, ripe fruit, offering that perfect combination of power and elegance.

What lies beneath makes all the difference. Paso Robles' rare calcareous soils and incredible diversity give our Syrah and Petite Sirah the foundation to develop concentrated flavors while maintaining the crisp acidity that keeps you coming back for more

Petite Sirah absolutely loves Paso's warm days and diverse soils. The long, hot days with cooler evenings create concentrated flavors and high acidity to balance the high sugars. The result is a wine with all that signature boldness and color, but with the structure and balance that keeps you coming back for another glass.

Perfect Pairings

Both wines are food-lover's dreams, but they shine in slightly different scenarios.

Syrah loves well-seasoned meats—think dry-rubbed brisket, herb-crusted lamb, or grilled steaks with peppercorn sauce. Its savory notes and moderate tannins make it incredibly versatile at the dinner table.

Petite Sirah demands heartier fare. We're talking braised short ribs, wild game, BBQ pulled pork, or even a juicy burger with sharp cheddar. The wine's powerful tannins need something substantial to grab onto, and it can stand up to the boldest flavors.

Bold wines deserve bold flavors. Syrah's peppery elegance pairs beautifully with herb-crusted lamb, while Petite Sirah's powerful tannins stand up fearlessly to rich, slow-braised short ribs. The only question is: which pairing will you try first?
