Connect with V&E extension and outreach peers at a virtual meeting of the National Viticulture & Enology Extension Leadership Community (NVEELC) on July 16! Get state reports from CA and the PNW and an overview of @WineAmerica's 2025 Economic Impact Study.

This article is among the last #graperesearch legendary viticulturist Richard Smart was working on before his passing on July 2. Revisiting the theme of canopy design and sunlight interception, it updates concepts in his seminal book, Sunlight into Wine.

@ucdavis Link above isn't working? Try this one:

A study from @ucdavis shows that eating grapes daily can help postmenopausal women fight muscle decline. In a 6-week trial, consuming grape powder (~1.5 cups of fresh grapes/day) improved grip strength, gait speed and muscle hormone levels. #graperesearch

Due to its volume of produce, CA has more refrigerated space than any other state, says Nicola Twilley, author of Frostbite: How Refrigeration Changed Our Food. Refrigeration changed what it means for food (incl table grapes) to be fresh. #graperesearch

A real-time vine nutrition sensor developed at @UC_DigitalAg passed its first field test at the @Cornell Lake Erie Research and Extension Lab in May, correctly IDing N, P and K levels in grape leaves. It’s part of the @HiresVineyard project. #graperesearch

After a hail event in MI in June, @MSUExtService advised grape growers to act fast. "The first 7 days (are) a critical window during which targeted interventions can dramatically influence the vine’s ability to recover this season and next." #graperesearch

Yellow Speckle viroid? Rupestris Speckle? Mostly, these colorful spots on grape leaves don’t signify production problems, Dean Volenberg (@Mizzou) reports. But symptoms can mimic black rot, which is another story. Best to know your dots!.#graperesearch

Grape breeders at @Cornell, @UMNews, @UArkansas, @TAMU and private company @GardensAliveInc are creating new table grape varieties for new markets. Whether vinifera or muscadinia crosses, these fresh-market cultivars are pushing boundaries. #graperesearch

What's new in #graperesearch? Click to our June newsletter to find out! Enjoy some positive thinking, learn how and which biofungicides stand out, sign up for the 7/16 NVEELC meeting and gross out over this gnarly photo from @CornellAgriTech's Dave Combs!

The New Zealand Wine Centre Scientific Research Conference awarded this article best viticulture research paper this month. It's the first report that grapevine trunk disease “escape vines” have a different microbiome than infected vines. #graperesearch

The next virtual NVEELC meeting will be Wed., July 16. If you're a viticulture or enology extension or outreach specialist, you're invited! The July meeting will feature CA and NW region reports and the @WineAmerica 2025 Economic Impact Study. Sign up now!

Tune in as @Cornell’s @kaitlinmgold talks about managing grapevine diseases…and fungicide resistance. Biologicals work by activating the plant’s defenses, she says. They don’t act on the pathogen at all, so there's no risk of resistance. #graperesearch

Drone delivery services rely on hyperlocal weather conditions, driving a revolution in forecasting. Innovators are using IoT to connect billions of devices, incl barometric pressure sensors in cell phones, for 10m resolution or 1 city block. #graperesearch

#Graperesearch led by the UK’s @niabgroup is combining companion plantings, biostimulants, biopesticides and ecoacoustic technology to improve biodiversity, soil health and sustainability without impeding wine quality.

According to a @WineMktCouncil survey of US wine drinkers, the #1 reason to buy eco-friendly wines is "to support the farmers and producers of these types of wines." Concerns for personal health and the environment also rated highly. #graperesearch

NGRA Board member Anji Perry of @JLohrWines takes a practical approach to vineyard nutrition, using 5 factors to guide her nutrient decisions: soil quality, water quality, YAN (yeast assimilable nitrogen), leaf analysis and visual symptoms. #graperesearch

A #graperesearch team at @PennState used 13C pulse labelling to find out if spotted lanternfly exposure affects grapevine carbon dynamics post-infestation. They found notable shifts in carbon allocation, with more 4x less 13C in roots after SLF removal.

Seeds, pollen and plant cuttings (including grapevines) from the @USDA_ARS National Plant Germplasm System are used to develop new varieties, traits or market uses to grow crop value, enable more sustainable farming and foster resilience. #graperesearch

#Graperesearch by @virginia_tech's Jaclyn Fiola shows that the mineralogy of vineyard soils can confound assessment of plant-available potassium. Standard soil tests plus tissue testing can more reliably quantify this often misunderstood macronutrient.
