Suisun Valley’s Climate Revealed Through a Study of Terra Spase

Friday, August 13th, 2010

In May of 2008, Suisun Valley Vintners & Grape Growers Association hired Terra Spase of Napa, California, to begin the process of scientifically defining their terroir. Proprietor Paul Skinner and his staff immediately initiated Phase I, which was to inventory and assess the conditions of the available climatic and topographic data for the Suisun Valley AVA.

On July 8, 2008, Terra Spase delivered Phase 2 to SVGGA, which included the data compilation phase consisting of the various datasets for analysis, including the following:

  • Narrowing target climatic parameters
  • Processing supplemental PRISM (Parameter-elevation Regression on Independent Slopes Model) weather dataset for analysis and mapping
  • Extracting target parameters from PRISM and local climate datasets
  • Target parameters summarizing for key time periods
  • Processing of elevation data in preparation for mapping the GIS analysis
  • Promising trends in data

On February 3, 2009, Paul W. Skinner, PhD delivered his “Climate, Topography and Wine Grapes in the Suisun Valley AVA” report to the Suisun Valley Grape Growers Association Board of Directors’ meeting, commissioned by SVGGA. In his introduction, Skinner indicates that because high intensity climate monitoring has been implemented in Suisun Valley with the installation of several automated weather stations, documentation of mesoclimates within the established AVA has provided a valuable, historical record from which to draw upon, in order to deliver the report.

Skinner writes, “The establishment of their own weather station network to collect weather data on a 24 hr basis by the Suisun Valley grape growers shows forward thinking on their part. It was also an important step forward for the Suisun Valley Grape Growers Association to recognize the value of developing this report for the use of the wine community and their constituents.” It is Skinner’s hope that Terra Spase’s analysis of the climate data that was collected [to date] will become the basis for an improved understanding of how weather and climate attributes define Suisun Valley AVA’s potential for producing world class grapes from different wine grape varieties.

Terra Spase recognizes Suisun Valley’s AVA with the following:

  • Located in the North Coast AVA, Suisun is one of the oldest, continually producing wine grape zones in the West.
  • It is increasingly recognized as a significant player in California’s luxury and ultra-premium wine grape market segments.
  • Wine grapes support in-valley wineries, as well as wine companies in Napa and Sonoma.
  • SV grape growers produce popular wine grape varieties, such as Cabernet Sauvignon, Sauvignon Blanc, and Chardonnay; as well as specialty cultivars, such as Syrah, Petite Sirah, Barbara, Grenache, Sangiovese, and Zinfandel.

Noteworthy climate findings include what was once empirically understood by the farmers and discussed as anecdotal evidence, and are now validated by this academic study; namely, situated in close proximity to the San Francisco Bay complex, portions of this area exert influence on the regions’ climate.

The report delivers the AVA’s geography in great detail; which to date has yet to be so thoroughly recorded. Considering all aspects of elevation, slope, and distribution aspects, the report recommends that if the wine grape growers take all aspects of the detailed topographical effect into account in the designing and production phases of their vineyards, development will significantly increase their likelihood of producing ultra-premium grapes and wines from their vineyards.

CLIMATE DATA AND MONITORING EFFORTS: The Terra Space report delivers extensive maps, which present a visual account for all of Terra Spase’s findings (examples):

  • Suisun Valley AVA and Vicinity
  • Separate maps for Elevation, Slope, and Aspect
  • Automated Weather Stations in the Suisun Valley AVA
  • Separate Precipitation, Humidity, and Temperature maps

Extensive charts deliver extensive supporting material for all of their findings (examples):

  • Seasonal Precipitation (in) 1995-2008; (CIMIS 123)
  • Monthly Precipitation (in) 1999 (CIMIS 123)
  • Mean Weather Precipitation (in) 1995-2007 – CIMIS 123
  • 2007 Monthly Rainfall (in) Williams2 and Abernathy 1 stations.

With data from the following sources, much was demonstrated from the average monthly temperatures from Terra Spase’s initial findings. [Used with permission of Terra Spase.]

  • CIMIS 123 ~ California Irrigation Management Information System: lowest, southwest
  • AB1 ~ Abernathy 1: southeast quadrant
  • AB3 ~ Abernathy 3: south, mid-valley
  • SSV ~ Suisun Valley: west, mid-valley
  • GV ~ Gordon Valley; central, upper-valley
  • WL2 ~ Williams 2: northwest quadrant
  • PRISM ~ Program at Oregon State University developed by Dr. Christopher Daly, the PRISM group director.

Suisun Valley’s unique, distinguishing features:

  • Precipitation ~ Springtime rains can occur after mid March bud burst, but are relatively unusual. This relative absence of late spring rain in Suisun Valley is a climatological advantage the region enjoys over many other winegrape growing regions.
  • The absence of precipitation during the summer months allows for the early ripening of relatively disease free winegrapes.
  • Growing degree day data indicate conditions range from Winkler’s Region III to Region V, within Suisun Valley AVA in different years, defining the quality of their winegrapes.
  • As a characteristic of many California coastal valleys opening onto the San Francisco Bay complex, the northern parts of the Suisun Valley region tend to see higher maximum and lower minimum temperatures than are observed in the southern parts of the region.
  • The lower portion of the Suisun Valley is subject to steady southwesterly, bay influenced breezes beginning in the late springtime. Annually occurring springtime northwesterly flow along the Northern California coast pushes marine air into the San Francisco bay and up through the San Pablo bay into the Suisun Valley region.
  • Suisun Valley’s eight-mile length of Springtime (March-April) Growing Degree Days are very closely aligned to Napa Valley’s 30 mile stretch, just in a condensed version.

Suisun Valley Vintners & Growers Association Honors Rick Wood and Fairfield Council Members

Monday, August 9th, 2010

On August 7, 2010, the Suisun Valley Vintners & Growers held their annual meeting. This gathering is the one  time each year that everyone in the valley, and those who support the valley,  come together to celebrate their accomplishments.

Each year the meeting is held at one of the wineries, with the meeting location being shared, from year to yea. This year’s host was Wooden Valley Winery.

A special surprise was included in this meeting. Awards were presented by President Roger King, to those who had the wisdom, foresight, and generosity to establish the Suisun Valley Fund. Click here for the full details of that fund.

This fund was created and supported by members of both the Fairfield City Council and the Solano Irrigation District. These two entities approved the fund, which was designed to have grants that have totaled nearly $2 million, to last over a seven year period.

Rick Wood was the first to recognize and understand that to preserve Suisun Valley as an agricultural entity would provide tremendous benefit to not only Solano County, but also to its citizens. For that, Mr. Wood was the first to be recognized for his forethought.

The five Fairfield council members who approved this funding. They were the following:

  1. Jack Batson
  2. Karin MacMillan
  3. Harry Price
  4. Marilyn Farley
  5. John English

The five directors from the Solano Irrigation District, who were honored for their foresight and generosity by approving the Suisun Valley Fund, were the following:

  1. Bob Bishop
  2. Guido Colla
  3. Robert Currey
  4. Robert Hansen
  5. Marion Maginnis – Posthumously

At the end of 2010, the “Suisun Valley Fund” and the “Suisun Valley Fund Advisory Committee” will cease to exist; however, all of the programs implemented during that time will live on historically for Suisun Valley, and they are momentous for all growers in this Suisun Valley AVA.

Quoting Jack Batson: “In 2000, Rick Wood, who was Manager of the Water Division for the city of Fairfield, entered into negotiations with the Solano Irrigation District, so that Fairfield and SID and would give the valley farmers another chance to save their agricultural region.

“Wood’s idea was as innovative as it was historic. The “Second Amended Agreement” of 2002 extended the term of the 1974 agreement from 2006 through 2010, and created the “Suisun Valley Fund” and the “Suisun Valley Fund Advisory Committee,” to run the fund. Both parties would put $100,000 per year into the fund for eight more years and adjust the yearly amount for inflation. The $1,600,000+ would be spent to promote the marketability of valley produce and to create other mechanisms to “preserve and enhance” valley agriculture that would continue past 2010. The Committee would be composed of two members each from the Fairfield City Council and the Solano Irrigation District, and three valley landowner/growers chosen by the two agencies.”

The Fund, now nearing its end, has made a significant impact. Its accomplishments include the following:

  1. Funding for the start-up and development of the Suisun Valley Grape Growers Association (now Suisun Valley Vintners and Growers Association).
  2. Organization of Suisun Valley retailers into a Harvest Trails group (now merged with the Suisun Valley Vintners and Growers Association).
  3. Funding for the start-up and development of the Suisun Valley Wine Cooperative (winery and tasting room for smaller production growers).
  4. Professional design and production of a logo and Harvest Trails map/brochure.
  5. Three weather stations for real-time data and microclimate analysis (added to Solano Irrigation District’s three stations making a total of six stations in the valley. The data is now adequate for microclimate studies like other major wine grape growing area
  6. Space on a new I-80 freeway sign and reader board at the Fairfield Auto Mall (i.e., the Fairfield “Jelly Belly” sign), inviting travelers to “Visit Suisun Valley.”
  7. Directional “wayfaring” signs at a dozen intersections in Suisun Valley.
  8. Funding for a “Mother Earth” public art piece at the Abernathy Road/Rockville Road entryway roundabout (with Solano County).
  9. Funding for an influential “Agricultural Vision and Economic Innovation for Suisun Valley” report by the American Farmland Trust Consulting (March 2007), as part of background studies for the Solano County General Plan Update (with Solano County), resulting in Solano County expressly supporting the continuation and facilitation of agriculture in the valley in its new General Plan.
  10. Employing the services of an “Agricultural Ambassador” for outreach to Suisun Valley growers and to staff Committee projects.
  11. Web page design and maintenance (www.SuisunValley.com).
  12. Promotional events, notably “Fun Family Farm Days,” staffed by the Agricultural Ambassador and volunteers.
  13. New relationships within the valley and new emerging leadership among the landowners, to face the future.
  14. The creation of a “Vision for the future of farming in Suisun Valley” (incorporated into Solano County’s Suisun Valley Strategic Plan, February 2010)

The Story of the Suisun Valley Fund

Tuesday, July 20th, 2010

Written for Suisun Valley Vintners and Grape Growers, by Jack Batson

The Suisun Valley grew up with the infant state of California.  It provided meat and grain to the miners of the 19th Century gold and silver rushes.  Later, with the advent of the Transcontinental Railroad which ran through its eastern edge, and especially with the invention of refrigeration, it provided early ripened fruit to a colder Midwest and East.  The valley was laced with rail lines and packing sheds.  The coming of the automobile brought the famed Lincoln Highway (US 40) through the valley, connecting San Francisco to New York City.  Business was brisk.

In 1957 the US Department of Reclamation completed Monticello Dam, creating Lake Berryessa.  The Solano Irrigation District (SID) delivered the water, and with the new supply, the Suisun Valley added a second growing season to its production.

Yet trouble was mounting.  Highway 40 turned into US Interstate 80, and the population of the Bay Area began growing east.  The Sacramento Valley began growing competitive crops and often used more modern methods in larger scale.  Suisun Valley’s principal fruit crop, canning pears, fell from favor.  Processing plants closed one by one.  And the valley was a developer’s “dream come true” with 7,000 acres of flat, well watered land adjacent to a major transportation artery.  Several land speculators began buying land, and the City of Fairfield annexed parts of the valley.

Still, the Solano Irrigation District fought back.  In 1974 it sued the city to protect its rate base, and the two agencies signed an agreement stating that neither would provide water to the valley for urban purposes through 2006.

There were encouragements.  In 1982 the valley received its own American Viticultural Area (AVA) designation, followed by its inclusion in the prestigious “North Coast”AVA along with Napa, Sonoma, and Mendocino Counties in the next year. But as the 20th Century neared its end, development pressures and the loss of profitability of the valley’s family farms began to come together.  If farmers could not make money, development would become inevitable and the valley’s rich soils would be lost to a sea of housetops.   The bankruptcy of the Tri Valley Growers coop in 2000 hit the valley’s growers hard; their accumulated retained earnings, usually earmarked for their retirement, disappeared.  Ominously, the Solano Irrigation District hinted that it might not renew the 1974 agreement when it expired in 2006.

The City of Fairfield took notice.  Having local agriculture nearby was seen as a city amenity.  Its beauty was widely appreciated.  People enjoyed driving through the valley, buying fruits and vegetables and sampling the local wines.  City leadership began to think strategically.  Their 1992 General Plan spoke directly of the need to protect the valley.  They understood that in the long term, valley farmers had to become profitable for the valley to survive development pressure.  Who would buy the valley’s produce?  The rich Bay Area, only 30 minutes’ driving time away, offered great possibilities.  The emergence of people highly motivated to eat “fresh and local” foods – “foodies” – was encouraging.  More and more people sought the “organic” label.  Interstate 80 carried almost 200,000 automobiles through the valley every day.  What if even one percent – 2,000 autos – would stop and buy some fruit or wine?  There were causes for optimism, but the “highest and best use” still pointed to development.  The valley needed a catalyst to bring the possibilities together.

In 2000 Rick Wood, Manager of the Water Division for the city of Fairfield, entered into negotiations with SID and both parties agreed to give the valley farmers another chance.  Wood’s idea was as innovative as it was historic.  The “Second Amended Agreement” of 2002 extended the term of the 1974 agreement from 2006 through 2010, and created the “Suisun Valley Fund” and the “Suisun Valley Fund Advisory Committee,” to run the fund.  Both parties would put $100,000 per year into the fund for eight more years and adjust the yearly amount for inflation.  The $1,600,000+ would be spent to promote the marketability of valley produce and to create other mechanisms to “preserve and enhance” valley agriculture that would continue past 2010.  The Committee would be composed of two members each from the Fairfield City Council and the Solano Irrigation District, and three valley landowner/growers chosen by the two agencies.  The five Fairfield council members who held office and voted to approve the funding of Suisun Valley Fund were Jack Batson, Karin MacMillan, Harry Price, Marilyn Farley, and John English.

The Fund, now nearing its end, has made a significant impact.  Its accomplishments include the following:

  1. Funding for the start-up and development of the Suisun Valley Grape Growers Association (now Suisun Valley Vintners and Growers Association).
  2. Organization of Suisun Valley retailers into a Harvest Trails group (now merged with the Suisun Valley Vintners and Growers Association).
  3. Funding for the start-up and development of the Suisun Valley Wine Cooperative (winery and tasting room for smaller production growers).
  4. Professional design and production of a logo and Harvest Trails map/brochure.

  10. Employing the services of an “Agricultural Ambassador” for outreach to Suisun Valley growers and to staff Committee projects.
  11. Web page design and maintenance (www.SuisunValley.com).
  12. Promotional events, notably “Fun Family Farm Days,” staffed by the Agricultural Ambassador and volunteers.
  13. New relationships within the valley and new emerging leadership among the landowners, to face the future.
  14. The creation of a “Vision for the future of farming in Suisun Valley” (incorporated into Solano County’s Suisun Valley Strategic Plan, February 2010):

Suisun Valley is a unique farming region that supports profitable family farms and quality of life for all its residents.  It is a destination for tourists seeking world class wine, identifiable Suisun Valley farm products and a beautiful agricultural landscape with no fallow land. The SV appellation is so famous that it creates new markets and increases demand for Suisun Valley wine and other farm products outside of the region.

This vision statement summarizes the goals of the Suisun Valley Advisory Committee.  It has been endorsed by the Committee, the city of Fairfield, the Solano Irrigation District, the Suisun Valley Fruit Growers’ Association, the Suisun Valley Vintners and Growers Association, the Solano County Farm Bureau, the City of Suisun, the Solano Land Trust, and the Solano County Agriculture Advisory Committee, and now, Solano County.
