Our Vineyards
 
At Sebastiani Vineyards & Winery, we are proud to work with grape growers that observe the same viticultural methodologies and practices that we implement in our own vineyards. Canopy management, vine nutrition, natural pest control, sustainable winegrowing, careful clonal and rootstock selection and deficit irrigation are all vital components in growing high quality grapes. Many of our prized vineyard blocks are "Old Vines" that were planted 30-110 years ago, tended by the second, third and even fourth generations of the original owners.

Sonoma County is segmented into twelve sub-appellations, each with unique topography and weather. We source fruit from seven of the sub-appellations. Listed below are brief descriptions of the unique growing regions and descriptions of the vineyards within those sub-appellations that we use today.


Sonoma Valley
Located at the southern tip of Sonoma County, the Sonoma Valley appellation encompasses the town of Sonoma, runs north along Highway 12 through the Valley of the Moon -- flanked by the Mayacamas mountain range on the east and Sonoma Mountain on the west - and ends southeast of Santa Rosa. Fog and breezes from San Pablo Bay cool the lower end of the valley and Pacific Coast influences cool the north end of the Valley. The middle of the Valley is the warmest area.

The region's climate and mostly volcanic, well-drained soils create an ideal environment for Cabernet Sauvignon, Merlot, Zinfandel, Barbera and Mourvedre grapes. Cool climate varietals such as Pinot Noir, Merlot and Chardonnay do well in the southerly vineyards bordering on Carneros, while Zinfandel flourishes on the arid, rocky slopes of the Mayacamas.

Sebastiani Vineyards & Winery is located within the Sonoma Valley sub-appellation along with several of our most prized vineyards.

The Sebastiani Vineayrds' Cherryblock is one of the great names in California Cabernet Sauvignon, and its source, the Cherryblock Estate Vineyard, is the quality and historical touchstone for Sebastiani Vineyards & Winery. With its welcoming Stone Arch, well-drained, reddish soils and divided canopy trellising planted on a gently sloping hillside, Cherryblock Vineyard is a landmark in Sonoma County and producer of one of the world's finest Cabernet Sauvignons.

Located just north of the winery at the edge of the town of Sonoma, the Cherryblock Estate Vineyard is planted primarily to Cabernet with a small amount of Merlot. Winery founder Samuele Sebastiani purchased the property in 1919 and planted a cherry orchard and grapevines in the traditional Italian style. His son, August, cleared the property and planted 11 acres of Cabernet in 1962, selecting superior budwood and grafting it onto phylloxera-resistant St. George rootstock. It proved to be a wise move, for Cherryblock has matured into a vineyard that consistently produces grapes with deep colors, complex flavors and ripe tannins.

The soil is a well-drained, reddish-brown volcanic ash type called Manzanita and the climate (Davis Region II) offers warm days and cool evenings. The late-ripening Cabernet grape likes some heat during the growing season and is a good match for many sites in Sonoma Valley. Cherryblock is unique in that it is situated at the southern end of the valley and gets kissed by cool evening air from San Pablo Bay. The swing in the day-to-night temperatures at Cherryblock allows the grapes to mature slowly and develop more complexity and structure than fruit from warmer vineyards farther north in Sonoma Valley.

Cherryblock Cabernet Sauvignon typically shows aromas and flavors of bing cherry, blackberries, currants, black olives and classic Cabernet "dust" framed by ripe tannins. The crunchy, tiny, inky black-blue berries from the nine-acre old-vine block at the top of the hill yield intense flavors due to their high skin-to-juice ratio, giving Cherryblock its concentration and opulence.

Carneros
Several of our most prized Chardonnay and Pinot Noir vineyards are located in this historic region. We are fortunate to have Estate vineyards planted to Chardonnay, Pinot Noir and Syrah, with plans to further expand the plantings throughout the next decade. Grapes have been grown in Los Carneros (commonly known as Carneros, which is Spanish for sheep or "the rams") since the second half of the 19th century, and although modern plantings did not take root until after World War II, it is considered one of California’s oldest wine districts. Agoston Haraszthy planted grapes in Carneros before 1870, undeterred by the persistent fog and vine-rattling winds. Originally a sub-appellation of Napa Valley, Carneros officially became an independent viticultural area in 1983. It spans the southern boundaries of both Napa and Sonoma counties (although the larger part of the appellation lies within Sonoma County), sprawls across the last, low hills of the Mayacamas Mountain Range and slips beneath the San Francisco Bay at the north end of San Pablo Bay. This region is particularly unique due to the coastal influences and the low, rolling hills of shallow soils that vary from thick clay to chalky and rocky alluvial deposits. Carneros benefits from the Bay’s cooling effects and the fog that the hotter inland areas draw over the land. The climate is ranked Region I, which is the coolest climate ranking; Carneros’ climate is similar to that of Burgundy and Beaujolais, which is why the region is known best for Pinot Noir and Chardonnay. When compared to other Californian appellations, Chardonnays from Carneros tend to have more aging potential, and Carneros Pinot Noirs are renowned for their opulence. Without the aesthetic charm of the valleys to the north, this desolate, windswept area's claim to fame is the quality of the wines it produces. We produce both a Chardonnay and Pinot Noir from growers active in the Carneros Quality Alliance.

Russian River Valley
This 150-square-mile appellation grows a number of grape varieties but it is the cool-climate-loving Chardonnay and Pinot Noir that make the biggest mark here. The Russian River Valley, which encompasses the Green Valley and Chalk Hill sub-appellations, has cool, foggy mornings and warm afternoons during the growing season, which favors early-ripeners like Chardonnay and Pinot Noir. Due to the cool conditions, these varieties mature slowly, which concentrates the character of the fruit without losing its natural acidity. The result is wines of great depth and balance.

One of our primary growers in the Russian River Valley is the Dutton Family, owners of the large Dutton Ranch vineyards. The ranch is not one contiguous vineyard but rather some 50 separate blocks, most of them in Green Valley in the southwestern corner of the Russian River Valley -the coolest sub-appellation in Sonoma County. The Duttons' own, lease or manage approximately 1,000 acres, and while the soils and microclimates vary, grape quality is uniformly high due to the overall growing conditions and the Duttons' expertise. The ranch employs "sustainable, minimum-input" farming techniques that show responsible stewardship of the land and improve wine quality. They also pioneered the introduction of Dijon clones to Sonoma County vineyards.

The Sebastiani family has maintained a warm relationship with the Duttons over the years and the grapes have long been a vital part of the winemaking program. Dutton Ranch fruit is the foundation for the Appellation Selection Russian River Valley and Sonoma County Chardonnays. Sebastiani's Russian River Valley Pinot is comprised of Dutton Ranch fruit.

Alexander Valley
This is the longest and most homogeneous viticultural area in Sonoma County. Located in northern Sonoma County, this appellation borders the Russian River from just east of Healdsburg and extends north to Cloverdale. It is comprised of rocky hillsides, valleys, riverbeds and benchlands. The Alexander Valley is one of the warmer areas of Sonoma County, as fog is not as prevalent there; the low hills just northeast of Healdsburg shelter the area from the ocean influences. It is considered a Region III climate, which is a warmer climate similar to that of France’s Rhone region. Because of the climatic conditions and rich, gravelly loam soils, the vines are vigorous with large leaf canopies. Canopy management techniques such as leaf pulling and shoot thinning are used to direct all of the energy and vigor of the growing vine toward the fruit. Alexander Valley is renowned for the voluptuousness of its wines. Both Cabernet and Merlot from this region feature ripe berry and fruit flavors, and a full body. The warm day and cool night temperatures coupled with the heavily graveled and sandy loam soils that characterize this region produce Cabernets with lush, black cherry fruit and earthy, terroir flavors. Alexander Valley Cabernets are known for their soft and fluid tannins, which make them more approachable in youth yet still capable of longevity. The alluvial soils also contribute a distinctive almost chocolaty richness to Cabernets grown in this region. Alexander Valley Merlots are often characterized by plum and currant flavors. We produce both appellation selection Cabernet Sauvignon and Merlot from the Alexander Valley.
