SUSTAINABLE GRAPE GROWING
Sunstone has been committed to growing wine grapes without the use of herbicides, pesticides, or synthetic fungicides since the initial planting in 1990. Sunstone’s estate-grown wines are the product of a vineyard in harmony with the Earth’s cycles throughout the year. “Not only do organic vineyards and toxin-free soils more accurately reflect the Santa Ynez Valley terroir, but they also respect our consumers’ health and the health of the people that work here,” explains Chief Executive Officer, Djamila Cabugos.
The fundamental philosophy for producing high-quality wines at Sunstone is to preserve the inherent quality of the grapes at every step in the grape growing and winemaking process. This holistic approach also creates a healthy environment in which to work and live.
“There was once a time when pesticides were thought to be the universal remedy to agriculture. The concept of disrupting eco-balance was non-existent, and the belief that ‘the only good bug was a dead bug’ permeated society,” Director of Winemaking, Brittany Rice, explains. “We are constantly experimenting with different methods to achieve a natural balance in the vineyard, which can be severely disrupted by the ‘quick-fix’ employment of herbicides or pesticides. We use cover crops, like barley, which not only generate competition with the vines, but also host beneficial insects. This type of equilibrium is an ongoing process that we are constantly fine tuning each day.”
Brittany claims “It is really wonderful to work with fruit that has no residual pesticides. I feel that the vines tend to be healthier, and organic farming is certainly the way of the future, as we will have to use a more sustainable approach to agriculture as a way of caring for the world that we live in.”
Santa Barbara County
Santa Barbara County is home to some of the most distinctive viticultural growing conditions in the world, with three individually identified viticultural areas: Santa Ynez Valley, Sta. Rita Hills and Santa Maria Valley. While most mountain chains in North and South America run north/south, Santa Barbara County has two ranges running east/west – the most clearly delineated east/west transverse ranges between Alaska and Tierra del Fuego on the Pacific Coast of the Americas. The mountains come together in a V-shaped orientation and, coupled with their proximity to the Pacific Ocean, channel fog and cool ocean breezes through the Sta. Rita Hills into the Santa Ynez Valley, creating a unique climate for wine growing.
Santa Ynez Valley
In 1983 the Bureau of Alcohol, Tobacco and Firearms (BATF) recognized the Santa Ynez Valley as a unique viticultural area. More than 4,000 acres of vineyards are planted in this region at elevations ranging from 200 feet near the Santa Ynez River to 1,500 feet in the foothills of the San Rafael Mountains.
The soils vary from gravelly loams and clay loams to shaly and silty clay loams. All soils have excellent drainage. The climate of the Santa Ynez Valley is extremely diverse, yielding many different mesoclimates. The Santa Ynez Valley varies from a Low Region I at the west end (Highway 101) to a warm Region II further east (Lake Cachuma) on the UC Davis climate degree day scale. As one moves due east into the valley from Buellton, the average temperature usually increases about one degree for each mile travelled.
The Santa Ynez Valley AVA—and in particular the middle and eastern portions of the AVA—is well-known for the production of high quality Rhone and Bordeaux varietal wine grapes, which require relatively high temperatures (degree days) to ripen fully.
Sunstone’s estate vineyards are situated in a moderate to warm Region II mesoclimate, in an area of the Santa Ynez Valley that typically sees a 30 to 40 degree Fahrenheit diurnal temperature fluctuation during the summer. As a result of the mild winters here, the growing season typically starts earlier than most and we harvest later due to cool, breezy evenings and foggy mornings. Because of this, we experience an extended ripening period, causing our grapes to develop an uncommon intensity of flavor and aroma.
The Santa Ynez Valley has been under the ocean several times in the past 150,000 years. Sunstone’s vineyards are deeply rooted in a subsoil of near-vertical Monterey shale, the result of these thousands of years of marine deposits and geological uplift. Closer to the surface, the Santa Ynez River has exposed and imported many younger soil types, such as sand, gravel, and loam, which are somewhat nutrient deficient and excellent for drainage.
Sunstone’s estate vineyards run parallel with and step down to the Santa Ynez River and offer two principal soil types. According to a 1988 survey conducted by Thomas Dibblee, Jr., the Sunstone Estate is planted on three terraces, each on a foundation of Monterey shale of early to late Miocene age. The upper terrace of “white-weathering, thin-bedded, hard platy to brittle siliceous shale” is from the Mohnian Microfaunal Stage. Beneath that, and on Sunstone’s lower terraces, is “white-weathering, soft, fissle to punky, semi-siliceous, phosphatic and calcareous shale with many thin carbonate strata from the Luisiana and Relizian Microfaunal Stages.
Director of Winemaking
Brittany’s family history is deeply rooted in viticulture and enology. From her great grandfather Fredrick Doak, a vineyard owner in Napa Valley that sold his grapes to vintners during the early nineteen-hundreds pre-prohibition, to her parents Fred & Linda Rice, founders of Sunstone.
Brittany helped plant the first merlot vines on the family property in 1990, which is known today as block B in the Sunstone vineyard. At the age of sixteen, she began serving wine to visitors and guests in the family tasting room. When she was twenty one, she worked in the cellar alongside winemaker Daniel Gehrs, the family’s winemaking consultant from 1999-2006.
In 2005, while entrenched in crafting the family wines, Brittany embarked on a new passion project, which would focus on small lot, unfined and unfiltered organic Bordeaux blends. Millesime Cellars was born and in that first year Brittany made only 100 cases.
In 2019, Brittany returned to Sunstone to take over winemaking from her brother, Bion, who led winemaking at Sunstone from 2011-2019.
Based on the Rice family’s values, Sunstone is an environmentally responsible company dedicated to organic grape growing, worker health, recycling and reusing whenever possible. We are completely dedicated to excellence in grape-growing, winemaking, hospitality and a highly-ethical responsibility to the people we hire and serve. The relationships we foster with our customers, employees, farmers, purveyors, contractors and community members is paramount. Everything we do contributes to these relationships.
Sunstone’s twenty-eight acre vineyard was planted in 1990 to Merlot, Cabernet Franc, Syrah and Viognier is farmed in an organic, bio-sustainable manner. Sunstone is dedicated to producing world-class Bordeaux and Rhone style wines, utilizing organically grown wine grapes from the estate vineyards, and grapes from other certified organic vineyards. The fundamental philosophy for producing high-quality wines at Sunstone is to preserve the inherent quality of the grapes at every step in the grape growing and winemaking process. This holistic approach also creates a healthy environment in which to work and live.
