Eagle Peak Mendocino County - Wine Region of the Day

The proposed Eagle Peak Mendocino County viticultural area is another region proposed by Ralph Jens Carter.  In the process of creating Eagle Peak, Mr. Carter proposed editing the already existing Mendocino and Redwood Valley appellations so all three viticultural areas were separated with no overlapping territory.  

Eagle Peak Mendocino County is so named as there are nearly fifty “Eagle Peak”s throughout the United States.  Mendocino County was added to the proposed name to clarify its location.  

The area is slightly over 26,000 acres in size of which 120 are under vine in 16 commercial vineyards and surrounds the summit of Eagle Peak.  The rocks in the area are mostly shale and sandstones from the Franciscan Complex which are found on rolling to steep, unstable slopes and terraces.  These rocks tend to be high in nickel and magnesium which can have negative impacts on grape vines.  Fortunately, the soils are thin and rocky allowing for the optimum canopy to maximize sunlight exposure.  Thin soils on steep slopes are subject to erosion but hold enough moisture to avoid the use of irrigation until after the period of fast growth called “grand growth stage”.  

The elevations in the viticultural area range from 800-3,320 feet which protect vineyards on the high slopes from frost by allowing cool air and excess water to drain into the surrounding valleys.  The slopes are largely south facing giving the vineyards longer daylight.

The region is known for producing Cabernet Sauvignon, Petite Sirah, Pinot Noir, Primitivo, Syrah and Zinfandel.

San Antonio Valley - Wine Region of the Day

---

The San Antonio Valley received its designation as an AVA in 2006. The San Antonio Valley is located in Monterey County and is bordered to the west by the Santa Lucia Mountains.

Unlike many of the wine regions in the United States, there is a long history of viticulture in the San Antonio Valley.   It was home to the Mission San Antonio de Padua that was founded in 1771 by Father Junipero Serra.  Franciscan Missions in Alta California could not rely on supplies from Spain and were required to be self-sufficient.  This meant making flour for bread and grapes for wine.  The Mission is still in operation as a parish church and visitors can see the original wine pressing vats and wine cellar.

The valley is located in the southern part of Monterey County and is located between the Santa Lucia Mountains near the Salinas Valley and includes San Antonio Lake and Fort Hunter Liggett Military Reservation.  The terrain contains gently rolling hills which form a basin or bowl shape.

The climate is typically warm and dry but benefits from the cooling breezes of nearby Lake San Antonio and the Pacific Ocean.  The region averages approximately 3,000 GDD on the Winkler Index indicating that it is the prime climate for Bordeaux and Rhone varietals.  The cool marine air that is so common for Monterey County is mostly absent. The region tends to be hotter and drier during the growing season but cooler during the spring and autumn.

Soil composition is also unique in San Antonio Valley.  Nearby Hames Valley is primarily composed of soils from the Lockwood series that are alluvial fans and terraces of siliceous shale.  San Antonio Valley has a more varied soil profile with 40 different types being represented.  The soil is primarily gravelly loam and clay that are mostly alluvial but with more gravel, sand and clays in the mix.

The region is known for its production of Bordeaux and Rhone varietals but is becoming home to Spanish and Portuguese grapes as well.  You can find Albarino, Barbera, Cabernet Franc,  Cabernet Sauvignon,  Chardonnay, Dolcetto,  Grenache,  Malbec,  Marsanne,  Merlot,  Mourvedre,  Petit Verdot, Petite Sirah, Pinot Grigio, Primativo, Roussanne, Sangiovese, Syrah, Tempranillo, Tinta Cao, Tinta Roriz, Touriga Francesca, Touriga Nacional, Zinfandel being produced in San Antonio Valley.

Templeton Gap District - Wine Region of the Day

The Templeton Gap District is nestled between the Paso Robles Willow Creek District and the El Pomar District near Templeton, California.  The Templeton Gap consists of a series of mountain passes created by rivers and creeks in the Santa Lucia Range through which marine air flows into the region.  This is referred to as a water gap in Geology.  The name “Templeton Gap” was coined by Ken Volk of Wild Horse Winery to describe the area and has since been adopted by the fellow winemakers and the local real estate industry. 

The Templeton Gap is the coolest climate of the Paso Robles sub-appellations and receives approximately 20 inches of precipitation per year. The water gap allows marine influences to enter the region which moderate the daily temperatures and increase the amount of time that it takes for grapes to ripen.  The elevations in the area range from 700 to 1,800 feet above sea level with the majority of the wineries located between 800 and 940 feet.

The location of the vineyards is largely along the wide terraced banks of the Paso Robles Creek and Salinas River.  The soils were created by alluvium of the Monterey Formation and are largely made up ofsilty and clay loans though there are some older soils produced from the Paso Robles Formation that are more cemented and shaly.  Grapes produced include Cabernet Sauvignon, Carignane, Charbono, Chardonnay, Grenache, Merlot, Petite Sirah, Pinot Gris, Pinot Noir, Primitivo, Sangiovese, Syrah, Tempranillo, Viognier and Zinfandel.
