Rodger Mohme, owner, proprietor, and chief field hand of Colina d'Oro Vineyards,
found his way to Paso Robles from Silicon Valley in 1999.
After several tours of duty in the
high tech industry, including almost 15 years with Apple, Rodger and Jayne decided to simplify
things a bit and take up... farming!
Rodger now works full time in the vineyard from
April thru October and in the 'off season' enjoys maintaining his engineering skills doing
consulting work for a medical devices company in SoCal. Mostly, he and Jayne enjoy spending time with
their family (two golden retrievers, cat and guinea pig) and their many good friends.
Hobbies include playing lead guitar in blues/rock bands whenever he gets the opportunity and
solving farming-related calculus problems as they arise.
Colina d'Oro Vineyards was established in 2000 on 20 acres (14 planted) of prime Paso Robles rolling hills.
All farming is done sustainably, and the vineyard is proudly
Composed of deep, complex calcareous soils, hills of various elevations, excellent drainage and the
maritime influence of the reknowned Templeton Gap, the Paso Robles wine region, and Colina d'Oro in particular,
comprises a world class terroir, as well as the ability to craft some of the world's best wines.
A meticulous farming regimen of pruning, shoot thinning, leaf thinning and cluster dropping result in benchmark
yields of approximately 2.5 - 3 tons per acre.
Cooling breezes blow almost continuously, especially in the afternoons, due to the proximity of the Templeton Gap,
a breach in the Coastal Range that allows air to flow from off the ocean to our inland location.
The area is characterized by cool, clear mornings,
warm-to-hot days, and nighttime temperatures that can drop by approximately 40 degrees.
Colina d'Oro Vineyards' location
We are located on the Central Coast of Calfornia, about halfway between Santa Barbara and Monterey,
and approximtely 4 hours south of San Francisco.
US-101 and the Salinas River split the region into two excellent (and distinctly different) growing
regions on both the east and west sides of town.
Why Paso Robles?
Paso Robles has a unique combination of attributes that make it ideal for growing world-class quality wine grapes.
- The highest diurnal (day/night) temperature variance of any viticultural area
in the United States:
In the summer months, it is routinely in the mid 90s to low 100s during the day. However, the dry climate
and close proximity to the ocean provide a exceptionally cool nights, often down in the low 50s.
- Incredibly diverse microclimates: Paso Robles has wide differences
in elevation and proximity
to the Pacific Ocean, which gives enormous climatic diversity. Its cooler areas (principally the
Templeton Gap area) specialize in Pinot Noir, Syrah and Zinfandel. Its higher-elevation, mid-climate areas
(principally the Adelaida Hills area in the north-west quadrant of town) is producing award winning
Zinfandel and Rhone Varietals, while its warmest areas (east and north of town) specialize in Bordeaux varietals.
No other American AVA has as much diversity.
- A reliable climate: Paso Robles is far enough south that it rarely rains
allowing growers and winemakers the opportunity for long hangtime and optimally ripened grapes.
At the same time, the hot days are balanced by the cool nights, leading to harvests in late September,
October and often November.
- Tremendous soils: Paso Robles has wonderfully diverse soils,
including the largest exposed
limestone clay layer in California. Limestone is common in many of the great wine regions in Europe,
including Burgundy, Alsace, the Loire, Chablis, and the southern Rhone, but rare in California.
It is not found in Napa, Sonoma, Mendocino, the Central Valley, eastern Santa Barbara County, or
Southern California. It is, in fact, only found in a narrow irregular band stretching through the Central Coast.
