overview of
SANTA BARBARA COUNTY
History
• 1782 - Father Junipero Serra planted
Mission vine cuttings in what is now the
Milpas District of Santa Barbara
• 1804 - Adobe winery constructed in
Goleta
• By late 1800's - 45 separate vineyards
encompassing 260 acres of land are
cultivated to wine grapes.
• 1884 - Justinian Caire imported grape
slips (vitis vinifera) from France and
planted a 150-acre vineyard on Santa
Cruz Island
• 1933 – Prohibition repealed
• 1960's - First commercial vineyard planted
by Uriel Nielsen and Bill De Mattei in the
Tepusquet region of Santa Maria Valley
American Viticultural
Area (AVA) Definition
• Determined by the Alcohol and Tobacco
Tax Trade Bureau
• As of 2/2016 there are 233 AVAs
nationwide
• They are determined by:
• Evidence that the name of the proposed
AVA is locally or nationally known as referring
to the area
• Historical or current evidence that the
boundaries are legitimate
• Evidence that growing conditions are
distinctive
• Contrary to Appellation or DOC/DOCG
systems of Europe they do not restrict
varietal use
• 85% of grapes grown
Fast Facts
• Six approved AVAs. 200+ wineries.
• 21,500 acres planted. Half the size of
Napa Valley.
• Three top varieties: Chardonnay, Pinot
Noir, and Syrah
• More than 50 different varieties grown
• Longest transverse coastline from Alaska
to Cape Horn, South America. Transverse
mountain ranges of Santa Ynez Mountains
and San Rafael Mountains pull cool
temperatures off the Pacific Ocean.
Fast Facts
• Great natural acidity, hence age ability of
the wines
• Long hang-time ensures grape complexity
• Large diurnal temperature shifts
• Vast majority of wineries and vineyards
are family owned and many with
production under 10,000 cases
• Location of the famed movie, Sideways
Geology
• Region is a tectonic train-wreck. Pieces of
the continent transferring over to another
plate, rotating and shearing as an old
subduction zone travelled underneath
• 40 million years ago the East Pacific Rise
(an oceanic spreading center) hit the
Southern Coast of California, the inception
of the San Andreas Fault
• As the spreading center got sucked under,
the San Andreas fault became a huge
right lateral fault
• 20 million years ago an area just north of
San Diego fragments off and is spun
around to finally rest where Santa Barbara
is today
Topography
• Santa Barbara’s Wine Country is bordered
by the Transverse Mountain Ranges:
•North side – San Rafael Mountains connect
to the Santa Ynez Mountains above Santa
Barbara
•South Side - Santa Ynez Mountains travel
East-West towards Los Angeles
• This area is is split horizontally down the
middle by the Purisima Hills, rendering
essentially two very distinct valleys
(northern Santa Maria and southern Santa
Ynez Valleys)
• Both of these distinct valleys open to the
Pacific Ocean at sea level and rise to
eastern peaks above 5,400 ft.
Climate
• Santa Barbara Country has very diverse
climates for a grape growing region
• Using the Degree Day Summation it runs
from Region 1 in the West (Sta. Rita Hills)
to Region 3 in the East (Happy Canyon)
• Nightly fog advances up the valleys
followed by daily retreats which further
accentuates these climatic regions
• Fog’s role brings a moisture rich
atmosphere that renders higher phenolics
• Due to the different zones, different
varietals excel
California Bump
• Santa Barbara’s wine country has a right
triangle shape on the west-side adjacent
to the ocean.
• Santa Ynez Mountains are responsible for
the “Bump” in the California coast line.
• This bump are the origins of a dramatic
oceanic current shift that occurs at Point
Conception. The California current
travelling south runs into the So Cal
countercurrent, bringing warmer water
and creating water temperature
differentials.
• The topography, with an open western
side and a pinched down valley on the
eastern side, also accounts for the daily
fog advance and retreat
Soils
• Born of many of these Geologic events
millions of years ago, most of the vineyard
soils in are relatively younger depositions
• We see two main themes
 Clayey Loams
 Sand
• Sub-strata which again takes the origins
of the deep marine environments brought
to the surface. Diatomaceous earth is
found in the western end intermixed with
Clay loam, like Botella formation. Further
east there is more limestone, more
compacted chalks under the sand.
• Nearly all of the vineyards are found on
the valley floors or alluvial fans coming off
the slopes

SANTA BARBARA COUNTY
Santa Ynez Valley
• Established: 1983
• Climate: Less marine influence than
Santa Maria Valley because the hills to the
west prevent marine influence deep into
the valley. Less moderated climate and
warmer overall temperatures.
• Elevation: 200 - 1,700 feet
• Rainfall: 10 – 17 inches
• Degree days: 2,680
• Soils: Gravelly and clay loam with seven
major soil associations.
• Principal varieties: Cabernet Sauvignon,
Cabernet Franc, Merlot, Sauvignon Blanc
Happy Canyon
of Santa Barbara
• Established: 2008
• Climate: Warmest micro-climate in Santa
Barbara County. Summertime
temperatures in the low to mid 90s.
• Elevation: 500 – 1,500 feet
• Rainfall: 10 – 12 inches
• Degree days:
3,300
• Soils: Mixture of loam and clay loam with
red and yellow chert and serpentine
cobbles. Soils are generally high in
minerals and low in nutrients, resulting in
smaller vines and high quality grapes.
• Principal varieties:
Cabernet Sauvignon, Sauvignon Blanc
Sta. Rita Hills
• Established: 2001 (2005 renamed)
• Size: 30,720 (planted and non)
• Climate: Region is exposed to fog and
coastal breezes from the nearby Pacific
Ocean. Hills run east to west, allowing
cool ocean breezes to enter the valley.
• Elevation: 200 - 1,700 feet
• Rainfall: 10-12 inches
• Degree days: 2,200
• Soils: Loam, sandy loam, silt loam and
clay loam.
