Promotable California Table Grape Volume Continues Through December
With promotable volume of California grapes available through December, retail promotion and consumer advertising continue through year-end in the U.S., and in Canada, Mexico, and other key export markets, according to Kathleen Nave, president of the California Table Grape Commission. Noting that harvest is still underway in some areas, Nave said that in a typical season California ships grapes throughout the U.S. and to multiple export markets into January and this year looks to be no different.
“The U.S. is a good market for California grapes,” Nave said, “and even better this season in terms of demand and price than it has been in recent years.” Noting that the U.S. retail commitment to stick with California through December – as opposed to focusing on imported grapes – remains strong, Nave added that Canada, Mexico, and Central America have all been particularly good markets this season with exports to Australia, Japan, New Zealand, Singapore, South Korea, and Taiwan steady, in spite of the worldwide shipping issues.
In the U.S. and Canada, Nave said late season retail promotions include sales contests, retailer tagged media support, and retail dietitian consumer-based outreach programs; advertising on digital television, social media platforms, digital and terrestrial radio, and shopping apps are part of the mix. Advertising continues in December in Mexico and key markets in Central America, with retail promotions scheduled in those export markets and multiple others.
According to Nave the 2021 crop volume has been tracking close to that of 2020 for most of the season. The 2020 crop volume was 101.1 million 19-pound boxes with 20 million boxes shipped after November 15.

WG Edge Partners with Sonoma County Grape Growers Foundation to Create Opportunities for Women in Ag
With its stated goal to preserve the legacy of agriculture in Sonoma County, the Women Gaining an Edge (WG Edge), a local leadership development program aimed at strengthening the region’s agricultural workforce, announced today that it will make a grant to the Sonoma County Grape Growers Foundation to administer the program.
WG Edge was created by Judy Jordan, formerly of J Vineyards and Winery and founder of Geodesy Wine, with the goal of advancing the next generation of women leaders in agriculture and wine. Core tenets of the program include scholarships for women studying ag at SRJC, internship opportunities through business leaders, and connectivity to a network of women leaders in the local wine and ag community who advise and open doors for the recipients on their career paths.
“We are excited because WG Edge and the Grape Growers Foundation are aligned in our missions to be a champion for and strengthen our agricultural workforce, who are critical to sustaining farming in Sonoma County,” said Jordan. She added, “Working together to build future leaders we believe will amplify the positive impact on our ag community.”
Supporting the next generation in Sonoma County is critical to the health of Sonoma County’s workforce. As with many areas in the country, in recent years, Sonoma County has experienced a notable loss of younger members of the workforce who have moved to bigger cities and other states in search of better opportunities. If Sonoma County can provide a pool of skilled talent, there will be qualified people who can assume leadership positions and help preserve locally owned companies and ranches.
To address this challenge, WG Edge was established with a big vision and goal to lift up young women in ag and surround them with support. The program has been very successful with 85% of the participants gaining internships during their first year in the program and program “graduates” going on to four-year universities.
“We are thrilled and honored to work with Judy, her team, and WG Edge on this important program to support younger women aspiring to work in agriculture and to participate in their development as local leaders,” said Karissa Kruse, president of Sonoma County Winegrowers and the executive director of the Sonoma County Grape Grower Foundation. She added, “I have personally been part of the WG Edge mentor network over the past two years and have seen firsthand the value of supporting the next generation of women to reach their full potential. We recently surveyed nearly 1,000 vineyard workers in Sonoma County and learned that 90% of them would recommend agriculture to their family and friends. Now with the WG Edge program grant, we are able to create more opportunities for families to thrive and preserve our agricultural legacy in Sonoma County.” -
Runze Cliff Yu Joins the Fresno State Department of Viticulture & Enology
The Department of Viticulture and Enology at Fresno State has a new assistant professor joining the faculty. This new assistant professor is Dr. Runze Cliff Yu. A Fresno State V&E alumnus, Yu finished his master’s degree at Fresno State in 2016 before moving on to UC Davis. He earned his PhD degree in June 2020 there and stayed for another year as a post-doctoral researcher.
Yu is excited to share his knowledge and experiences with the students in the department. Yu also has an extensive research background. Working with his advisor Dr. Kaan Kurtural for many years, his research focuses on the current issues Central Valley wine grape growers have been experiencing, such as drought, heat and labor. He is planning to conduct research around these topics.
“Teaching and research should be mutually inclusive in viticulture,” said Yu. “We need to provide our students with the latest research and innovations. They are the future of this industry and will need to be equipped to solve problems and move the industry forward.”
Yu is very happy to back in the department. “It feels like coming back home,” he said. “I look forward to working with both students and grape growers to do my part to further the success of the grape industry.”

Mitigating the Uncertainty of Smoke Taint in Wine Grapes
Smoke taint has dominated the worries of the California wine industry recent years. With unsettled climate conditions and continued droughts, there is no reason to think that smoke taint will not continue to be a significant concern for the foreseeable future. In 2017 and 2020, California growers and wineries both had to scramble to adapt as they found that existing science, customs and contractual arrangements left them ill-prepared to deal with the smoke taint challenge. Avoiding a similar situation once smoke taint inevitably strikes again means understanding the problem and having a strategy in place to address it.
What is smoke taint?
Drinking smoke-tainted wine has been compared to tasting a campfire or an ashtray: most would agree that these are not desirable attributes for wine. These off flavors are caused by volatile phenols that are released by plant matter when it burns. The volatile phenols bond with sugars in the grapes, which produces glycosides. Unlike volatile phenols, glycosides are not volatile, so the smoky quality cannot be smelled or tasted.
The Problem of Uncertainty
During a typical crush, grapes are harvested in the field, delivered to the winery crush pad, inspected, accepted if there are no obvious signs of defects, and the fermentation process begins. If the winery buys the grapes from a grower, acceptance typically obligates the winery to pay the grower, with payment due shortly after harvest, or in installments, the first shortly after harvest and the second a few months later.
However, one of the biggest challenges of smoke taint is its latency. In effect, volatile phenols hibernate: Glycosides become volatile as the wine is fermented and aged and smoke can then be smelled and tasted. It is hard to predict when this will occur, making it difficult to detect, plan for and mitigate the risk of smoke taint during the usual wine making process.
Compounding the uncertainty, there is no universally accepted definition of smoke taint in the industry. Different laboratories and wineries rely on different levels of different chemical markers. Relying on taste and smell is inherently subjective, painfully obvious in some cases, subtle and hard to discern by some palates in others.
Contract Approaches
Ultimately, uncertainty breeds trust and relationship issues best solved in the grape purchase contract. Parties negotiating grape contracts should consider:
- Identifying smoke taint using specific chemical markers (perhaps periodically revisited in good faith during the contract as industry knowledge evolves) or using truly neutral subjective evaluators
- Using tiered pricing depending on the levels of chemical markers found
- Incorporating processes that recognize smoke taint’s latency by delaying acceptance of suspect grapes
- Allowing suspect grapes to be processed for the grower’s account
- Including a holdback of some portion of the purchase price
- Some combination of the above
Don’t Overlook Insurance
Growers and winemakers should review their insurance policies in detail before and after smoke taint strikes and consider working closely with a broker or lawyer to determine whether, when, and how to make a claim.
Understanding how insurance works with smoke taint now can help prepare you after smoke taint strikes. One of the trickiest issues is determining which insurance policy will cover a potential loss. As a general matter, crop insurance will cover damage to grapes while they are on the vine while other forms of property insurance will cover “damage” to grapes after they have been harvested. Growers with healthy crop policies should encourage field inspections before harvest to enable timely claims.
However, since it may not be clear when the grapes were “damaged,” steps taken under one type of policy could impact a claim under a different type of policy. If it is not clear when the grapes were damaged, potential claimants should review their policies carefully and work closely with their consultants, lawyers and brokers to determine the best approach to a potential loss.
Taking the time now to understand your policies before smoke taint hits can help make the claim process less stressful and ensure that no important steps are missed. Grape growers and winemakers should review their insurance policies to determine the supporting documentation required to file a claim. Some policies, for example, may require information about when the grapes were affected, where they were affected, and for how long.
Many policies will also require lab tests from preapproved labs that indicate the presence of smoke taint. At present, pre-harvest tests typically focus on the presence of guaiacol and 4-methylguaiacol and are performed either on whole berry clusters or after the micro-fermentation of samples. Although post-fermentation tests can help confirm the presence of smoke taint, many policies will still require pre-harvest test results.
Potential claimants should also look for other requirements that might affect the viability of their claim. Does a policy require winemakers to segregate the juice from different lots, and should this be part of grape contract negotiations?
Carefully reviewing insurance policies and closely working with your consultants, insurance broker and lawyer may also uncover unexpected sources of recovery. For example, if crop insurance is not available or does not fully cover the loss, it might still be possible to obtain coverage for lost profits and extra expenses due to grower’s inability to harvest grapes due to lack of access or other reasons, or a winery’s inability to procure the grapes it needs to produce wine. As always, to maximize insurance recoveries, it is necessary to quickly and thoroughly gather all relevant facts, supporting documentation and relevant insurance policies, and understand (with a professional’s help, if required) how the insurance policies might respond to particular losses before deciding how one or more insurance claims should be pursued.
Next Steps
Potentially ruined grapes are bad enough: the inherent uncertainty around smoke taint’s presence, cause, and extent exacerbates the related contract and insurance problems. To reduce this uncertainty: review insurance policies and grape contracts so you understand their terms, consider negotiating grape contracts to incorporate practical procedures, and reach out to your consultants, insurance broker or lawyer with any questions about contracts, policies, or general strategy for addressing potential smoke taint damage. Anything you do now can reduce the pressures of the next fire season. – By Matthew Lewis, Tyler Gerking & MaryJo Lopez

ARS, NASA Join Forces To Monitor Earth’s Water Supply

Bill Kustas, ARS hydrologist at Beltsville, MD, checks the position of a water vapor/carbon dioxide (CO2) sensor on a micrometeorological tower. The instrument measures the exchange of water, energy, and CO2 between the soil-plant system and the lower atmosphere (Photo by Peggy Greb). Scientists with the USDA Agricultural Research Service (ARS) have teamed up with NASA to use satellites to monitor the water cycle on Earth, specifically “evapotranspiration” — the amount of water that enters the atmosphere through evaporation and transpiration from plants. Transpiration occurs during photosynthesis when plants take up carbon dioxide and release oxygen.
That information is especially important for farmers because the data help them get the most from their farms and ranches.
“Evapotranspiration (ET) is an integral part of the water, carbon, and energy cycle of our water, soil, plant, and climate system,” said Bill Kustas, research hydrologist at the ARS Hydrology and Remote Sensing Lab in Beltsville, MD. “Most precipitation returns to the atmosphere in the form of ET, which accounts for two-thirds of the global annual average precipitation. Knowledge of ET is critical for monitoring plant and crop water use and stress, loss of water from lakes and reservoirs, and is essential for scheduling irrigation to maintain proper crop growth and development.”
NASA’s satellites track plant growth, cover and biomass, land surface temperature, and soil moisture — all key elements to ET and plant health. ARS scientists develop models from this information to map ET and plant/crop water status so farmers can maintain proper crop growth and development.
How can a satellite collect that type of information from so far away? According to Kustas, sensors on the satellites measure both reflection and emission of electromagnetic radiation from the land using visible, infrared, thermal-infrared, and microwave wavelengths. The data from these sensors provide unique information about water, soil, and plant properties and states.
“All plants transpire liquid water into water vapor that cools the plant so it can maintain a temperature range that is optimal for photosynthesis and promote efficient plant growth and development,” Kustas said. “This leads to the production of maximum crop yield.”
If the ET rate is not high enough, the plant will undergo stress. In the worst-case scenario, without any available water, plants wilt and die. Kustas said that farmers can avoid this by irrigating crops, but this can reduce water available for other uses, like municipal use and maintenance of healthy ecosystems. Knowing the actual ET rate helps farmers to better determine how much irrigation is needed to maintain healthy crops while reducing over-application and pumping costs.

Ranchers can also benefit from satellite ET mapping. “Ranchers can better manage the land’s grazing potential by moving herds or reducing herd numbers before overgrazing can affect land health and future productivity,” Kustas said.
“Water, specifically the amount and use of root zone soil moisture or plant available water, is the most critical limiting factor in agricultural productivity worldwide,” he said. “ET from satellite remote sensing is particularly important for global food security assessment, especially in water-limited regions that have little data to monitor crop conditions and project future yields.” — By Scott Elliott, USDA ARS Office of Communications
