Concord grapes ready for harvest*

WILD THINGS

In the last couple of months, a number of articles cropped up related to climate change and what it means for us as farmers and eaters. It’s as if, as more extreme and erratic weather swirls around us, the conversation is intensifying about how we might have to change, too.

 

In July, climate observer David Wallace-Wells opens an essay in The New York Times titled, Food as You Know It Is About to Change,” talking about disruption in the global food supply, citing rising food prices and hunger, and declining yields around the world. “But disruption is only half the story,” he says. “Adaptation and innovation will transform the global food supply, too… Climate-endangered foodstuffs will be replaced or redesigned. Diets will shift, and with them the farmland currently producing (them). The pressure on the present food system is not a sign that it will necessarily fail, only that it must change.”

 

Replaced or redesigned food? What does that mean? In many cases (and certainly in the case of grapes), it means a return to or reliance on lesser-known or indigenous varieties. Chef Marcus Samuelsson wrote just a few days ago about cooking with the little-known grains of Africa. “As climate change threatens the availability of global staples like wheat, rice and potatoes, we must diversify what’s on the plate,” he says. “Chefs have a role to play in putting these climate-friendly foods on the map. Demystifying a lesser-known ingredient is something we do all the time.”

 

The same could be said of winemakers. Indeed, of the 10,000 or so varieties of grapes in the world, only a handful—Cabernet Sauvignon, Merlot, Chardonnay, Pinot Noir, Sauvignon Blanc, Syrah and a few others—make up the lion’s share of global wine production. In projects like dear native grapes, and Hudon Valley Heritage, both in New York, heirloom or native grapes like Concord (shown above, typically used for juice and jelly), Delaware (a Hudson Valley-bred variety from the 19th century once widely planted across the US) and Aestivalis (a little-known North American native grape species) are being cultivated as quality, environmentally sustainable wines.

 

(As I also learned this month, bananas are in the same boat as grapes, if not worse. It is the world’s most consumed fruit. Yet a single variety, the Cavendish, accounts for almost half of all bananas grown globally. There are only about 1,600 known banana varieties; their DNA is stored in a gene bank in Belgium.)

 

And in labs around the world, the genes of Vitis aestivalis and other native grapes are sequenced and cataloged for use in creating new climate-ready grapes and improving the ones the world already knows and loves. As Samuel Peters, a farmer and agricultural researcher at the International Institute of Tropical Agriculture in Nigeria, explained in another article that recently crossed my desk, these “crop wild relatives” can have “many high-impact traits that could be studied and adapted to improve domesticated crops.” 

 

Using the example of how grafting Vitis vinifera vines onto Vitis riparia rootstocks saved the French wine industry from phylloxera, Samuel explains that cultivated crops (like vinifera grapes) are selected and bred for a narrow set of traits, potentially making them vulnerable to pests, diseases and changing environmental conditions. “Crop wild relatives didn’t go down the same evolutionary trajectory” as cultivated crops, he writes. “They remained in the wild, subject to natural selection.” Thus, these wild things could hold keys to sustaining agriculture, and grape and wine production, into a chaotic future.

 

As Hurricane Helene—the strongest hurricane to make landfall in Florida’s Big Bend region—unleashed record flooding through the Southeast last week and the West Coast copes with the ravages of wildfire, the effects of climate change are upon us. The question is, how and what will we change to adapt?

Cold-Hardy Grape Breeder Jim Luby Retires

The University of Minnesota’s legendary fruit breeder, Jim Luby, retired this summer. Since 1982, he has led the Department of Horticultural Science’s fruit breeding and genetics program which has released 31 cultivars of apple, grape, blueberry, strawberry, raspberry, pear and plum. He is one of the people credited with breeding the Honeycrisp, the most successful apple variety in the program’s history. 


But more importantly to the grape and wine world, Jim “helped put the cold-climate wine industry on the map,” said the department in a press release announcing Jim’s Lifetime Achievement Award from the National Association of Plant Breeders in August 2023. “Through the wine grape breeding program he led until 2015, five key cultivars were introduced that helped enable small, local vineyards and wineries across the Midwest to produce quality wines. This contribution to cold-hardy grape cultivars has become increasingly important as climate change continues to alter what we once knew as ideal growing locations and conditions.” The varieties Jim developed include La Crescent (with Peter Hemstad), Marquette, Frontenac, Frontenac Blanc and Frontenac Gris. 

EPA Extends Deadline for Comments on Mancozeb

The US Environmental Protection Agency (EPA) has proposed canceling the use of mancozeb in grape.

RESEARCH FOCUS

Of Balance and Bounties: Vineyard Nutrient Management 

By Nataliya Shcherbatyuk, Pierre Davadant and Melissa Hansen

Vineyard nutrient management often focuses on nutrient inputs that fertilizers, compost and cover crops add to a vineyard. Growers commonly use lab analysis of grapevine tissue (leaf blades and petioles) and soil samples to help them assess the nutrient status of their vineyard and guide nutrition management. But our research shows that nutrient outputs, as from harvested grapes and senescent leaves, can take more of a toll on vineyard nutrition than growers may realize. In fact, over the course of a four-year study, on average, more than 70 pounds of nitrogen, potassium, phosphorus and magnesium per acre were lost annually between harvest and leaf fall. 

 

Nutrient output study 

Although nutrient inputs have been well studied, there is little information about nutrient loss from harvested wine grapes—and even less on the impact of leaf fall on vine nutrition. Markus Keller, Chateau Ste. Michelle Distinguished Professor in Viticulture at Washington State University, guided a project to assess nutrient loss at the end of the growing season from harvested fruit and leaf fall. 

 

The vineyard trial took place in a commercial vineyard located in Paterson, WA, in the Horse Heaven Hills AVA. Harvested fruit and leaves of own-rooted Chardonnay (planted in 2010) and Syrah (planted in 1998) grapevines were analyzed for four years, from 2020 through 2023. Samples were tested for nitrogen, phosphorus, potassium and magnesium. Random samples of fruit from a one-acre block within the vineyard were collected, dried, ground and sent to a commercial lab for nutrient analysis. Nets were installed under random vines within the block to capture falling leaves after harvest. After the first killing frost, which is below 28 degrees Fahrenheit, the leaves were analyzed for the same four macronutrients as the harvested fruit. Yield averaged 6.6 tons per acre for Chardonnay and 4.8 tons per acre for Syrah.  

 

Losses from harvest and leaves 

Nitrogen removed during harvest averaged 2.8 pounds per ton for the four study years. While that may sound small compared to the volume of grapes, when calculated on a per-acre basis, it equated to an average of 23.3 pounds of nitrogen per acre removed annually. Other nutrients’ per-acre losses averaged 4.4 pounds of phosphorus, 41.3 pounds of potassium and 4.5 pounds of magnesium.  

 

Senescence, when leaves age and fall off, is crucial to future growth. As leaves age, key nutrients are relocated to storage organs for use in the next growing season. We found that nutrient losses from leaves showed more seasonal and cultural variation than the losses from harvested fruit. Chardonnay averaged a leaf-fall loss of 5.8 pounds of nitrogen per acre; Syrah averaged a nitrogen loss of 10.6 pounds per acre. Leaf potassium was most responsive to seasonal differences. Phosphorus showed no impact from the timing of frost. 

 

But what about leaves killed by an early frost? The 2020, 2022 and 2023 vintages were marked by fall frosts on October 23, November 10 and November 9, respectively. Obviously, when an early killing frost zaps leaves before their nutrients have been relocated, those vines may have lower stores of nutrients to support growth in the spring. And that’s what we found. The loss of nutrients was most pronounced in these years, when leaves were killed quickly by early frost rather than via normal senescence. Plus, if senescent leaves blow away (e.g., by wind), their nutrients aren’t recycled in the soil either. 

 

Vineyard nutrition is about balance. Nutrients play specific roles for different physiological processes, and vineyard managers must regulate the supply of macro- and micro-nutrients for optimal growth, fruit development and overall vine health. Both nutrient inputs and outputs must be considered to avoid nutritional deficiencies. If nutrients aren’t adequately replaced, the resulting imbalances can lead to reduced yield, delayed fruit maturity and compromised fruit quality.

IN THE NEWS

What to Know about Seasonal Calcium Accumulation in Grapevines

September 21, 2024 | Growing Produce

Grapevines accumulate a lot of calcium in their annual growth but mostly in leaves and, to a lesser extent, stems. The import of Ca into grape berries diminishes with development and virtually ceases after veraison, so grape berries are inherently low in Ca. That’s good news if you’re a wine grape grower. But table grape growers beg to differ.


AOC Vineyards Change Altitude in the Face of Climate Change

September 17, 2024 | Vitisphere

An appellation in France’s Loire region is the first to petition for changes due to climate change. Urban development is a factor, too. The president of the AOC Côte Roannaise, which spans 32 producers 182 hectares, has asked the National Institute of Origin and Quality (INAO) to permit the appellation to raise its elevation so growers may plant farther up the areas slopes. He says the change would eliminate gaps throughout the region caused by housing developments, delay budburst and achieve “more freshness in the wines.”


New Method May Help Wines Tainted by Wildfire Smoke

September 17, 2024 | Decanter

A team of Australian scientists found promising results “fishing” unpleasant volatile phenols out of smoke-affected wines using molecularly imprinted polymers (MIPs). In their research, beads of MIPs—synthetic material that can bind to target compounds—suspended in wine did ameliorated smoke taint, both in chemical and sensory analysis. But they also impacted other aroma volatiles and color. Researchers report that MIPs can be rinsed and reused. “Regenerating” them seems to enhance their effect.


A Breakthrough in Wildfire Detection: How a New Constellation of Satellites Can Detect Smaller Wildfires Earlier

September 16, 2024 | Google

Google Research is contributing $13 million to the Earth Fire Alliance to help launch the FireSat constellation of satellites designed to detect and track wildfires as small as a classroom (roughly 5x5 meters). FireSat will provide authorities with high-resolution imagery updated globally every 20 minutes to enable them respond to fires before they become destructive. The first satellite will launch in early 2025, with the full constellation to follow in the coming years.


Vitis Vinifera and Muscadines: Grape Breeders Seek the Best of Both Grapes

September 16, 2024 | Morning Ag Clips

A $7M USDA-NIFA SCRI grant will enable 32 scientists from 12 research institutions to explore ways to marry the best traits of muscadines (disease resistance and unique flavors) and Vitis vinifera (crisp texture and seedlessness). Because the two grape species have a different number of chromosomes, crossing them can be complicated. But this team, led by University of Arkansas’ Renee Threlfall and Margaret Worthington, is 10 years in the making. “Our goal is the introduction of disease-resistant cultivars with enhanced fruit quality leading to a more resilient US grape industry,” Renee said.


Can the Most Popular Red Wine in the US Endure Climate Change?

September 9, 2024 | NPR All Things Considered

Cabernet Sauvignon is the focus of this climate-focused segment. “In the face of climate change, wineries around the world are innovating. New technology is being installed to keep grapes cool during heat spells. A handful of wineries are going a step further. They’re experimenting with new grapes, ripping out high-value Cabernet vines to plant varieties from hotter climates. ‘We know we have to adapt,’” a Napa winemaker says.


UC Davis Winery Starts up New Clean-in-Place System

September 9, 2024 | Wine Business Monthly

The UC Davis Teaching and Research Winery has implemented a new clean-in-place (CIP) system. Beginning with this year’s crush, it will automate cleaning and sanitizing the winery’s 14 fermentation tanks, making the previously labor-intensive process faster and safer for workers, and more water-, energy- and chemical-efficient. It also educates students on modern industry-standard technologies so they may bring this knowledge into the wine industry. 


Assessing the Capacity of High-Resolution Commercial Satellite Imagery for Grapevine Downy Mildew Detection and Surveillance in New York State

September 8, 2024 | Phytopathology

Over three growing seasons, a Cornell team scouted grapevine downy mildew in a research vineyard, rating incidence and severity. They compared their results to imagery acquired within 72 hours of scouting from two high-resolution multispectral satellite platforms and found very high correlations. The results showed promise for incorporating satellite remote sensing in grapevine disease detection and surveillance systems.

NEWA leverages weather data to deliver accurate and precise short-term insect pest, plant disease and crop production risk forecasts. Through the partnership, more than 1,200 registered NEWA users now have access to hyper-local information from more than 285 combined weather stations.


Foliar Applications of Phenylalanine and Prohexadione Calcium for Managing Tannin Content in Cold-Hardy Hybrid Grape Cultivars

September 2, 2024 | Oeno One

Cold-hardy hybrid grape varieties like Marquette have lower tannins than Vitis vinifera. A team of researchers from Iowa State sought to see if common tannin interventions used for vinifera such as nitrogen fertilization and plant growth regulators could help. Although vintage variation had the most significant impact, results showed that foliar application of prohexadione calcium (ProCa) could hold promise, particularly for skin and seed tannin.


Know Your Soil and Grape Variety When Planning Vineyard Irrigation

September 1, 2024 | WBM Practical Winery & Vineyard Journal

Washington State University research exploring the extractable soil water thresholds of 30 winegrape varieties found differences in shoot vigor and the soil water thresholds at which vines feel stress. It also found that own-rooted vines differ from grafted vines. Growers can use this knowledge to better tailor irrigation to individual varieties.


Industry Roundtable: Vine Certification

September 1, 2024 | Wine Business Monthly

In this roundtable article, California clean plant experts John Caldwell (Caldwell Vineyard), Kirk Lokka (Emeritus Vineyards), and Maher Al Rwahnih (Foundation Plant Services) share expertise about selecting clones, testing rootstocks and ensuring vines are true to type and disease-free. They also talk about technological advances like virus testing tools and high-throughput sequencing that reduce the cost and improve the quality of certified plant material.


US Wine Industry Needs Are Similar Despite Regional Differences

September 2024 | Oregon Wine Research Institute

In a 2024 SCRI planning project, a team of 15 faculty and extension specialists from across the country set out to understand regional wine industry challenges in the US, then design research to address high-level issues of national importance. Results showed unified concerns across regions, with the same top three viticulture and marketing/sales challenges nationally. But for wine production, there was one notable exception. 


Effects of Germicidal UV-C Light on Grape Mealybug

September 2024 | Washington WAVE Report

Ultraviolet-C light has been shown to suppress powdery mildew, but can it be used to control other pests? A WSU-led study sought to understand if/how the technology could impact grape mealybug. It showed small but significant impacts on nymph mortality from UV-C treatments. More study is warranted for this promising finding.


South African Wine Producer Drone-Drops Wasps on Vineyard

August 29, 2024 | The Drinks Business

South Africa’s Vergelegen Wine Estate is dropping parasitic wasps on its vineyards via drone to combat mealybugs. The drones will release a plastic film carrying about 500 pupae of wasps that are indigenous there. It is hoped that, when they’re adults, the wasps will “lay eggs inside the mealybugs, eating them from the inside out,” thereby reducing the spread of leafroll virus “faster and cheaper than spraying pesticides.”


Dark, Hardy and Mysterious, the Lenoir Grape Has a Disease-Resistant Superpower

August 26, 2024 | Wine Enthusiast

Lenoir, a black-skinned winegrape variety with red flesh, is a boon to southern growers, due to its resistance to Pierce’s disease, and powdery and downy mildew. But making wine with it reveals less desirable traits like funky aromas, and color and tannin instability. Texas A&M extension enologist Andreea Botezatu has done research to help it “taste like something special.”


More New Fungus-Resistant Grape Varieties in France

August 2024 | BKWine Brief

Four disease-resistant varieties, all from Italian nursery Vivai Cooperativi Rauscedo, have been listed as approved varieties in France from now till their re-evaluation in 10 years. They are two whites—Kersus and pinot Iskra, both resistant to downy and powdery mildew—and two reds—Pinot Kors, resistant to fungal disease and Volturnis, which is highly resistant to downy but not powdery mildew.
