Calistoga

The northernmost sub appellation in Napa Valley and the furthest from the San Pablo Bay, Calistoga experiences some of the most dramatic daytime to nighttime temperature fluctuations during the growing season.

Climate

Very warm daytime summer temperatures that peak above 100°F but fall to the low 40s° at night due to cool marine air drawn into the valley from the northwestern hills. Cool afternoon and evening breezes.

Soils

Volcanic, rocky and gravelly

Characteristics

Bold, ripe and concentrated, with big tannins.

Atlas Peak

With elevations ranging between 760 and 2600 feet, Atlas Peak is a mountain appellation located on the western slope of the Vaca Mountain range.

Climate

Sunny, cool, and mountain-influenced, with temperatures about 10 to 15°F cooler than the valley floor in summer. Summer temperatures are rarely above 90°F.

Soils

Volcanic in origin, with basaltic red color, shallow and porous with limited water retention.

Characteristics

Bright berry and cherry fruit with firm acidity; complex, with velvety tannins.

Oak Knoll District

Climate

Located in the southern end of the valley floor, Oak Knoll features the largest alluvial fan in Napa Valley, formed by Dry Creek.

Soils

Volcanically derived soils, with stony or gravelly consistency. South and east areas are transitional from gravel to silty clay loam.

Characteristics

Volcanically derived soils, with stony or gravelly consistency. South and east areas are transitional from gravel to silty clay loam.

Oakville

This flat, mid-valley appellation was one of the first areas in Napa Valley to be planted, and is considered to be one of the finest for Bordeaux varietals.

Climate

Moderately warm, with temperatures commonly in the mid-90°F range in high summer, but also affected by night and early morning fog which helps maintain acid levels and balance.

Soils

Primarily sedimentary gravelly alluvial loams on the western side, with more volcanic but heavier soils on the eastern side. Low to moderate fertility and fairly deep, with average water retention.

Characteristics

Red and black fruit, often with notes of mint and herbs; rich texture and full, firm structure with fine balance.

Los Carneros

Bordered by the San Pablo Bay on the south, the wind-swept Carneros AVA is one of the most dramatic and unpopulated of Napa Valley’s sub-appellations. It is unique in that this appellation is located partially in Napa Valley and partially in Sonoma County.

Climate

Cool, with marine winds and fog from the San Pablo Bay and the Petaluma Gap to the west. Summertime temperatures rarely exceed 80°F and diurnal temperature changes are not as great.

Soils

Clay dominated, thin and shallow, with more loam and hillside alluvials in the north.

Characteristics

Bright acidity, red berry fruit; soft, fine tannins and sleek structure.

Rutherford

Home of Conn Creek Winery, and located in the heart of the valley. Some of the oldest and most historic wineries are located here.

Climate

Moderately warm, still marginally influenced by early morning fog from the south. Western bench area is cooler, tempered by afternoon winds. Summer peak temperatures are mid-90°F with good diurnal range.

Soils

Western benchland is sedimentary, gravelly-sandy and alluvial, with good water retention and moderate fertility. The eastern side has more volcanic soils, is moderately deep and more fertile.

Characteristics

Intense cherry and mineral aromas. Full, ripe red and black fruit flavors; firm, but supple tannins for extended aging.

Chiles Valley

Often described as a “valley within a valley,” this narrow appellation is tucked into the Vaca Mountain range on the northeastern side of Napa.

Climate

Warm summer days (mid-80°F plus), but due to higher elevation and summer fog, quite chilly at night. With colder winters and spring, harvest usually comes later than on the valley floor.

Soils

Alluvial with silty-clay composition of marine origin; good fertility. Clay-loam and stony-clay composition on hillsides with some volcanic outcropping.

Characteristics

Lush yet firm texture with good acidity, firm, velvety tannins and cherry-blackberry flavors laced with cocoa.

Spring Mountain

Steep terraces and high elevations characterize this appellation, which rises up from the valley floor on the Mayacamas range to the west of the town of St. Helena.

Climate

Long growing season with cooler days and warmer nights than the valley floor. Afternoon breezes, fairly cool nights, and higher elevations help maintain good acidity.

Soils

Primarily sedimentary; weathered sandstone/shale. Drainage is high, fertility low.

Characteristics

Powerful, firm, blackberry-currant flavors and often richly tannic, with excellent acidity for aging.

Coombsville

Located just east of the city of Napa, Coombsville is the most recent addition within the Napa Valley AVA bringing the total to 16 AVAs.

Climate

Temperate climate moderated by near-proximity to the San Francisco Bay and the influences of marine air.

Soils

Primarily weathered volcanic rock and alluvial deposits from the Vaca Range that surrounds the region.

Characteristics

Vineyards here possess a unique ability to achieve the black and blue fruit character found in warmer regions, but also able to produce more complex flavors and mineral tones found in cooler regions.

St. Helena

Densely planted with vines, the St. Helena AVA surrounds the northern Napa Valley town of the same name, where the valley floor begins to narrow as it continues its stretch to the north and west.

Climate

Warm, due to protection from western hills, with less fog and wind. The narrowing of the valley floor provides more heat reflection off the hillsides. Mid-summer temperatures often peak in the mid- to high 90°F range.

Soils

South and west borders are sedimentary, gravel-clay, with lower fertility and moderate water retention. Further north and to the east soils are volcanic, deeper and more fertile.

Characteristics

Deep, ripe, concentrated flavors, with firm tannins and appealing aromas of currant and black fruit.

Diamond Mountain

Sits on the western Mayacamas Range just south of Calistoga with elevations ranging from 400 to 2000 feet. Rocky terrain.

Climate

Moderately warm temperatures but significantly cooler than the valley floor below.

Soils

Volcanic, often reddish and very fine-grained.

Characteristics

Firmly structured, powerful, rich and fairly tannic when young, with strong black currant, mineral, and cedary flavors. Good aging potential.

Stags Leap District

Lies just below the Vaca Mountains on the Valley's east side. Only 1 mile wide and 3 miles long, it was the first US AVA to be approved based on the distinctiveness of its soils.

Climate

Moderately warm, with afternoon winds that cool the warmer air radiating off the bare rocks of the hillsides. Mid-summer temperatures are regularly in the mid-90°'s F range.

Soils

Volcanic gravel-loams on the valley floor, with rocky hillsides and low to moderate fertility due to hard clay bedrock subsoils.

Characteristics

Lush, velvety texture and fine perfumed cherry and red berry flavors, supported by soft tannins.

Howell Mountain

Ruggedly beautiful, it overlooks St. Helena from its perch on the Vaca Range which borders the valley on its eastern side.

Climate

Moderate temperatures due to high elevation; slightly warmer and drier than valley floor with strong afternoon sun. Fairly cool nights.

Soils

Predominantly volcanic and well-drained; shallow and infertile. Drainage is high, fertility low.

Characteristics

Powerful, firm, blackberry-currant flavors; complex, robust and often richly tannic, with excellent acidity for aging.

Wild Horse Valley

Napa Valley's smallest AVA, Wild Horse Valley is tucked into the southeast corner of the region, protected by low surrounding hillsides.

Climate

Sunny and warm due to its eastern location, but moderated by both altitude and prevailing winds coming off Suisun Bay.

Soils

Volcanic in origin, with basaltic red color; shallow with limited water retention.

Characteristics

Bright berry and cherry fruit; bracing acidity.

Mt. Veeder

This mountain appellation is on the southwestern end of Napa Valley.

Climate

Cool to moderate, with most vineyards above the fog-line, meaning warmer nights, cool yet sunny days and less diurnal range than the valley floor.

Soils

Sedimentary based, former seabed, shallow and generally well-drained. Most soils have a sandy or sandy-loam texture.

Characteristics

Low yields give red wines a firm, chewy, tannic structure with strong wild berry aromas and rich, spicy, powerful flavors. Ageability is a hallmark of Mt. Veeder wines.

Yountville

The first vineyards in the Napa Valley were planted here by George Yount in the mid-1800s and the town that bears its name has become a renowned epicurean center.

Climate

Marine breezes and fog contribute to a moderate climate, with cool summer mornings and afternoons. Mid-summer peak temperatures may reach 90°F with diurnal fluctuation to the mid-50°F range.

Soils

Mostly gravelly silt loams, sedimentary in origin, and gravelly alluvial soils with rock; moderately fertile.

Characteristics

Soft yet with bright acidity; red berry fruit aromas and rich, supple flavors and firm tannins.

Napa Valley AVAs

Only 30 miles long and five miles wide, Napa Valley offers a stunning diversity of soils, climate and topographical conditions. Napa Valley is home to 16 AVAs or sub-appellations and at Conn Creek Winery we source Cabernet Sauvignon grapes from nearly all of them. This gives us a unique expertise and an unparalleled array of choices from which to blend each wine and vintage.
