LEADERS SHOW UP

Leadership isn’t always easy. Like at most nonprofit organizations, leaders within the National Grape Research Alliance who serve as Officers and Directors of our Board take on important responsibilities. They help to ensure the organization operates smoothly, has clear strategic direction and successfully delivers on our grape research mission. And they set aside their individual business concerns to represent the grape and wine industry and advance our collective greater good.

U.S. terminates climate change regulation
New research finds regenerative viticulture is comparable to conventional grape-growing, financially speaking

NGRA Board Directors commit to three-year terms, which, at a time when the grape and wine industry is facing unprecedented headwinds, may be seen as a leap of faith. They’re asked to participate, preferably in person, in at least three Board meetings a year, held in locations around the U.S. It’s an expectation—and expense—that we don’t take for granted, especially as the industry faces economic challenges. Despite the many reasons not to, NGRA Board Directors show up and take a seat at the literal table to initiate novel research projects and programs to solve industry challenges, together.

So, it’s remarkable to note that, at our Annual Meeting in January, we not only re-elected three long-time Board Directors, but we also elected five new members to our Board. With thanks for their new or renewed commitment to service, they are:

Regional Representatives

Keith Striegler (GALLO), California Renewing
Nancie Oxley (St. Julian Winery, MI), Midwest Region New

Commodity Sector Representative

Eric Pooler (Nuveen Natural Capital, CA), Winegrape Sector New

At-Large Representatives

Paul Dray (American Vineyard Foundation, CA) New
Randy Heinzen (Vineyard Professional Services, CA) Renewing
Justin Jackson (New York Wine & Grape Foundation) New
Anji Perry (J. Lohr Vineyards & Wines) Renewing
Julie Tarara (Washington Wine Commission) New

We also re-elected four of our officers, and installed one new one. We’re grateful to these tireless champions who are elected annually and serve at our highest level of leadership:

Chair - Rich Schaefers (Nuveen Natural Capital, CA)
Vice Chair - Emily Hodson (Virginia Wine Board [Veritas Vineyard and Winery])
Secretary - Chad Vargas (Atlas Vineyard Management and Advantage Vines Nursery, OR)
Treasurer - Anji Perry (J. Lohr Vineyards & Wines, CA) New
Research Chair - Nick Dokoozlian (GALLO, CA)

Anji Perry is not new to the NGRA Board, but she is our new Treasurer. She succeeds Dan Martinez (Martinez Orchards, CA), who served as Treasurer for at least 10 years, bringing clarity and transparency to our financial reporting, and guiding NGRA’s first investments. We’re thrilled that Dan remains an At-Large Representative on our Board, and that Anji has stepped so gracefully into this vital role.

NGRA has a maximum of 30 Board Directors. Their renewable three-year terms are staggered so that about one-third of them expire each year. We consider it an honor that most of our Board members choose to renew their terms and are re-elected. We’re indebted to them for their time, attention, care and concern. Our research mission—and dare I say, the sustainability, competitiveness and profitability of the industry—depends on them. Please join me in thanking them and all our NGRA officers, Board and staff members for their service.

U.S. Terminates Climate Change Regulation

President Trump this month “terminat(ed) the so-called ‘endangerment finding,’” the bedrock scientific observation that climate change endangers human health and the environment. The announcement effectively ends the Environmental Protection Agency’s legal authority to control pollution. EPA Administrator Lee Zeldin called it “the single largest deregulatory action in the history of the United States.” The New York Times reports that “the action is a key step in removing limits on carbon dioxide, methane and four other greenhouse gases that scientists say are supercharging heat waves, droughts, wildfires and other extreme weather.”

Bayer Agrees To Pay $7.25 Billion To Settle Roundup Lawsuits

On Feb. 17, Bayer said that it had reached an agreement that would pay plaintiffs $7.25 billion to settle tens of thousands of lawsuits that claimed the weedkiller Roundup (active ingredient glyphosate) caused non-Hodgkin’s lymphoma. The agreement was submitted to a Missouri circuit court judge in St. Louis, but it has not yet been approved. A $10 billion settlement unraveled in 2020 after a judge objected to how future claims would be handled. The latest deal would cover both current and future claims, and create a fund that Bayer would pay into over the next 17 to 21 years, according to a company statement.

Dicamba Is Legal Again

The chemical, dicamba, was re-approved by the Environmental Protection Agency on Feb. 6 for use in controlling weeds in genetically engineered cotton and soybeans. A federal court had made certain uses of dicamba illegal in 2024 after some farmers complained about drift, damaging crops (like grapes) that hadn’t been genetically engineered to resist it. It was the second time courts had vacated EPA approvals of the weedkiller, each time citing risks that it would harm neighboring fields. The ban was scheduled to take effect last year.

But in its ruling this month, the EPA said its analysis had found no unreasonable risk to human health and the environment so long as dicamba was applied according to instructions. It did concede that dicamba’s risks to the environment were real, so it would add new restrictions to its use. Those restrictions include cutting in half the amount of dicamba that can be used annually; restricting use during hot weather, when the risk of drift is highest; and requiring conservation practices to protect endangered species.

U.S. Senators Recognize the Value of NASA to Agriculture

During the Senate confirmation hearing for NASA Administrator Jared Isaacman on Jan. 26, Senators Jerry Moran (R-KS) and Amy Klobuchar (D-MN) discussed the NASA’s impact not just on space exploration, but on earthly concerns like agriculture. “I don’t think many people understand that NASA’s Earth satellite data is hugely valuable for farmers,” said Sen. Amy Klobuchar of Minnesota. Specifically, the Senators acknowledged the role that NASA Harvest and its domestically focused sister consortium, NASA Acres, play in the global food system. NGRA is a member of the NASA Acres consortium and proudly supports the work Katie Gold and Yu Jiang at Cornell lead as part of it, using grape as a model system for advancing pest and disease detection via NASA technology.

U.S. Winery Count Declines

“The number of U.S. wineries declined for a third straight year as a weak wine market likely deterred new entrants and convinced others it was time to close shop,” reports WineBusiness Monthly. According to the WineBusiness Analytics Winery Database, there are 11,107 wineries in the U.S. now, 3% fewer than there were in 2025, and 4% less compared to 2024. That’s 512 wineries gone. Among western states, Oregon recorded a 3% increase in wineries thanks to an 11% increase in virtual operations, which brings the state’s total to 868 wineries or 47 more than Washington. The number of wineries in Washington declined 2% to 821. The two Northwest states account for nearly 16% of all U.S. wineries. The total number of wineries in California declined by 2% to 4,646, with the number of bonded operations falling 4% to 3,906 while virtual wineries grew 11% to 740. California accounts for 42% of all U.S. wineries.

Bipartisan Group Warns of Potential Ag Industry Collapse

A bipartisan group of trade association leaders from the corn, soybean, pork, barley, wheat, dairy and biofuel industries, former USDA officials, and agricultural economists and policy experts warned Congress this month about the farm economy’s deteriorating state. In a Feb. 3 letter to House and Senate Ag Committee leaders, they characterized current conditions as representing a potential “widespread collapse of American agriculture.”

“Farmer bankruptcies have doubled, barely half of all farms will be profitable this year, and the U.S. is running a historic agriculture trade deficit,” the letter states. “The reasons for the dramatic turnaround are complex, but it is clear that the current administration’s actions, along with congressional inaction, have increased costs for farm inputs, disrupted overseas and domestic markets, denied agriculture its reliable labor pool, and defunded critical ag research and staffing.” It lays out nine points to improve the ag economy, including exempting all farm inputs from tariffs, passing a new Farm Bill, and restoring federal funding for agriculture research and critical USDA staffing.

RESEARCH FOCUS

Comparing the Economic Viability of Regenerative vs. Conventional Viticulture

By Axel Herrera (UC Davis); Ellen M. Bruno (UC Berkeley), Kerri Steenwerth (UC Davis and USDA-ARS), Alexandra Everson (Jackson Family Wines), and Cristina Lazcano (UC Davis)

Regenerative agriculture (RA) is gaining attention for its potential to enhance sustainability in viticulture. RA practices support soil fertility, biodiversity and carbon sequestration (commonly referred to as ecosystem services). Studies have shown that RA practices may be particularly suitable for the production of winegrapes because the perennial nature of grapevines allows growers to capitalize on the often long-term benefits of RA. Furthermore, grapes may be particularly vulnerable to climate change, as increasingly intense droughts and higher air and soil temperatures pose significant risks to their phenology, yield, and quality. By improving soil health, RA practices can help mitigate the negative impacts of climate change.

Adopting RA can be hindered by a lack of information and a limited understanding of its economic feasibility. Despite growing evidence demonstrating RA’s potential environmental benefits for winegrape growers, concerns remain about its effects on winegrape yields and quality, with some studies indicating that outcomes may vary depending on site-specific factors and the specific RA practices implemented.

So, we undertook this study to investigate the farm-level economic implications of transitioning to RA in the winegrape sector, with a focus on California’s North Coast, specifically Sonoma County. Our goal was to objectively compare RA to conventional farming, to establish an understanding of costs and benefits for winegrape growers who are curious (or skeptical) about these practices.

We analyzed data from four Sonoma vineyards to evaluate the financial outcomes of implementing RA practices (e.g., cover crop, no-till, composting and livestock integration) relative to conventional viticulture (CV) practices in the region (i.e., cover crop, alternate-row tillage, synthetic fertilizers and herbicides). Our findings reveal that CV and RA practices result in comparable profitability over a 30-year time horizon, with RA averaging 5% lower net present value across vineyards, assuming no change in yields.

Outsourced RA services, such as composting and livestock grazing, account for a modest share of operational costs (7% to 8%). Managing these practices in-house may involve higher initial costs. Still, it provides long-term benefits, such as lower operational expenses, improved soil health and the integration of sheep grazing, which can result in 100% savings on mowing and herbicide application, eliminating these annual costs. In-house RA practices can yield higher financial returns (a net present value [NPV] of $557/ha) compared to outsourced options (NPV of −$1,756/ha).

Although RA profits are slightly lower than those from CV practices (−1.9% to −8.4% across vineyards), this difference assumes equal yields between management systems. The differences could be larger if RA causes yield declines. We also found that site-specific factors such as grape variety, vineyard layout, vine age and density, as well as the ability to obtain price premiums, affected RA’s economic viability and profitability.

Importantly, this analysis is based on existing vineyards transitioning to RA. For growers establishing new vineyards, there is an opportunity to select rootstocks, irrigation infrastructure, and vineyard design tailored to RA systems, potentially avoiding initial yield losses observed in transitions. This finding highlights the importance of site-specific planning and intentional design when adopting RA from the outset.

The results of this Sonoma County-based study suggest that RA practices can achieve economic outcomes comparable to CV practices over the long term, particularly in this region. RA does require careful management of yield effects and market conditions, and its positive impact can be aided by policies that recognize and reward the public benefits of these practices. Understanding the financial trade-offs and benefits of RA can help growers make informed decisions about transitioning to more sustainable viticulture practices. Future research should optimize RA practices for different vineyard conditions and quantify RA’s long-term economic and ecological impacts at scale.

A Valentine to the Vignoles

Feb. 17, 2026 | ARS Tellus

The French-American hybrid Vignoles is a popular white variety in the Northeast and Midwest, but its extremely compact clusters make it susceptible to bunch rot. After 19 years of advanced breeding and field trials, scientists at the USDA-ARS Grape Genetics Research Unit and Cornell AgriTech have developed a loose-clustered version called Vignoles 2 with comparable wine quality and an 80% reduced incidence of bunch rot.

Can Wine Appellation Systems Withstand Climate Change?

Feb. 16, 2026 | SevenFifty Daily

Last August, “top Pomerol estate Château Lafleur announced it would withdraw from both the Pomerol and Bordeaux appellations and instead designate all of its labels as Vin de France,” reports SevenFifty Daily. “The decision was driven by the producer’s need for greater flexibility when responding to climate change, as heatwaves and erratic weather increasingly challenge existing appellation regulations. Now, climate change is at the center of the debate over the relevance of geographical indications (GIs).”

‘Unprecedented’ Emissions Maps Will Hone Mitigation

Feb. 13, 2026 | Cornell Chronicle

Croplands constitute 12% of land use globally and account for 25% of greenhouse gas emissions within the agricultural sector. Cornell researchers synthesized data from multiple ground sources and models to map global cropland emissions at high resolution—down to about 10 km—while breaking down emissions by crop and source and identifying regions for more precise mitigation. As of 2020, fruits and vegetables accounted for about 7% of the world’s GHG emissions. Rice was 43%.

How Cover Crops Shape Grapevine Root Systems

Feb. 5, 2026 | Sustainable Winegrowing with Vineyard Team

Suzanne Fleishman, Assistant Professor of Root Biology at Penn State University, studies perennial crops through the lens of Root Agroecology. Roots don’t just anchor plants to the earth, they interact with their environment through a network of microbes, she says. For vineyards, managing root systems holistically, including those of grapevines and cover crops, can improve sustainability. For example, she shares insights from a five-year red fescue cover crop trial showing reduced pruning weights and improved vine balance.

Drones in Agriculture: Benefits and Regulations to Know Before You Fly

Feb. 3, 2026 | UCCE San Joaquin Valley Trees and Vines

If you fly a drone for any business purpose, such as scouting, irrigation checks or mapping, the Federal Aviation Administration (FAA) considers it a commercial activity. All commercial drone flights are subject to Part 107 of the FAA regulations governing small Unmanned Aircraft Systems (sUAS). Even if no money changes hands, using a drone “in furtherance of a business” requires compliance with Part 107 and a valid Remote Pilot Certificate. “While it might be tempting to ‘fly under the radar,’ the FAA doesn’t have much sense of humor about unlicensed operations,” writes UCCE’s Justin Tanner.

Tarara: New Tools For Grape Growers

Feb. 1, 2026 | Good Fruit Grower

With support from the Washington State Wine Commission, WSU’s Gwen Hoheisel and Michelle Moyer are working on digitizing the Grape Crop Protection Guide and developing a grape Decision Aid System (DAS) that work together online and on phones. “DAS combines all of the digitized information, like the environmental data from AgWeatherNet and the crop protection guide,” Gwen said. “Combine this with weather-driven models, and now growers will have the ability to make data-driven decisions.” The online guide and Grape Decision Aid System will be accessible in time for the 2026 growing season.

Rethinking the Rules for Various Vineyard Regions

Feb. 1, 2026 | Good Fruit Grower

Michigan State’s Paolo Sabbatini and Cornell’s Hans Walter-Peterson say that, although grape growers in cool-climate regions have managed to successfully grow Vitis vinifera grapes adapted to the more temperate climates of the Mediterranean and California, the management techniques they learned from those regions might be doing more harm than good to the vines in the long run.

Norton and Cynthiana: The Proof Is in the Wine

Feb. 1, 2026 | Wine Business Monthly

From 2022 to 2024, Stephan Sommer, then-extension specialist for enology at the Grape and Wine Institute at the University of Missouri (now at University of Tennessee), made three vintages of Norton and Cynthiana wines to demonstrate that Norton and Cynthiana are indeed different varieties, despite persistent confusion, including at the TTB. He found that Norton consistently had greater tannins and total phenolics, and more fruity, floral and fermented notes than Cynthiana.

Robot Bees Can Pollinate Crops

Jan. 31, 2026 | Offrange

Not grapes, but interesting: Dropcopter was invented by two innovators—one an olive farmer—to help tree fruit and nut farmers combat the rising cost of pollinating trees as bee populations continue to decline. Their patented, dinner-plate-size drones meter out pollen at a specific rate and steady speed, covering 40 acres in about four hours. By comparison, one person can manually pollinate five to 10 trees a day. These “robot bees” have been shown to improve yield by 25% in almond orchards and 45% in cherries.

Wine Minute: Surprises In Cold Hardiness Research

Jan. 30, 2026 | Pacific Northwest Ag Network

In this podcast interview, WSU’s Markus Keller shares unexpected findings from his team’s recent research on cold hardiness. “One surprise is that we actually don’t know how much water roots need,” he said. Unlike buds, grapevine roots cannot cold-acclimate. Water helps to insulate them, but how much is too much? To test out the extremes, “we completely over-irrigated vines during the ripening period (and) lost about 25% color on the berries.” That was the most surprising finding so far, he said, and something they’ll be digging into.

AI Surpasses Human Experts in Detecting Deadly Vine Disease in French Vineyards

Jan. 30, 2026 | Vinetur

A project seeking to systematically evaluate Champagne vineyards for flavescence dorée by humans reported only 50% detection…and burnout by the volunteer and professional experts surveying for the disease. The Comité Champagne has trained AI systems to ID it more accurately, achieved detection rates above 80% and as high as 94% under lab conditions. They’re trying to overcome technical barriers to deploying the tech in the field.

Hybrid Barrel Promises ‘Best of Both Worlds’

Jan. 30, 2026 | The Drinks Business

Austrian cooper Manuel Schön has patented the world’s first wooden wine barrel with a stone head. While heavier than a conventional oak cask, the Hybridfass is believed to deliver fruitier, fresher wine styles. “Stone is the calming element,” he says. “It hardly lets any oxygen through, does not require toasting and brings clarity, sometimes even a subtle saltiness.”

Seven New Swiss Grape Varieties Make Their Debuts

Jan. 29, 2026 | Swissinfo.ch

Agroscope, Switzerland’s center of excellence for agricultural research, has released seven new grape varieties that are resistant to powdery and downy mildew and have good wine quality. Crosses of American and Asian grape species, the new Swiss varieties are four whites (Forisia, Elaris, Orellis and Damona) and three reds (Valpesia, Dioniso and Taranis). While these fungal diseases typically require six to ten sprays a year in Switzerland, the new vines require only one or two, a reduction of more than 80%.

We Can Safely Experiment With Reflecting Sunlight away from Earth. Here’s How.

Jan. 6, 2026 | The Guardian

In 1991, the Philippines’ Mount Pinatubo erupted and sent about 15m tonnes of sulfur dioxide into the stratosphere, cooling the planet by about 0.5C. The event inspired the idea of stratospheric aerosol injection (SAI). Models suggest SAI could offset 1C of warming with about 12m tonnes of SO₂ per year—far less than emitted from industrial processes. Some worry that, done poorly, SAI could catastrophically shift precipitation patterns. “But that’s exactly why research is needed,” the authors write.

What Is a Healthy Soil for Winegrape Production? Grower Perspectives Differ from Soil Health Paradigms

Jan. 4, 2026 | European Journal of Soil Science

In a first-of-its-kind study, winegrape growers in Napa Valley participated in a UC Davis-led study to assess soil health in vineyards and link it to production outcomes. Researchers found that growers commonly rate their vineyard soils as “challenging” or “ideal” based on soil texture, specifically related to moisture management for vigor control. But several soil indicators linked to carbon and nutrient cycling and soil structural health were not among the factors growers look for in ideal soils.

Fungicide Resistance Monitoring and Management in US Vineyards

December 2025 | CAPCA’s The Adviser

When monitoring for fungicide resistance, it’s important to know not only how much resistance may have developed, but when. The scientists behind the Fungicide Resistance Assessment, Mitigation and Extension (FRAME) project advise that, while resistance is more likely to come later in the growing season, after foliar growth has slowed, sampling and testing for FRAC 11 resistance throughout the entire season can help you adjust your spray program and ensure continued use of FRAC 11 fungicides. The FRAME website has action plans.
