A @Cornell-led team evaluated the nighttime application of UV-C light to suppress 3 grapevine diseases—powdery and downy mildew, and sour rot—on Chardonnay and Vignoles in NY vineyards. In some cases, disease incidence was reduced to nil. #graperesearch https://t.co/WR5GCSdtmj

In this @NapaWineAcademy article, @jamiegoode breaks down #sensoryscience. He explains that, of the 800 to 1,000 #aromaticcompounds found in #wine, not all are smellable. But they may still affect your nose--er, #retronasalolfaction. #graperesearch https://t.co/tgvKGAGWc6

An extreme cold snap in CO's #GrandValleyAVA in Oct 2020 killed 70%+ of vinifera. But the #coldhardy vines some growers were experimenting with survived. Hybrids have grown from 1% of the state's plantings in the early 2000s to 20% today. #graperesearch https://t.co/etMabOVFz2

What 🍇 fruit quality and 🍷 quality attributes are controlled by the root? I don’t know but we are trying to figure that out. 150 mini vilifications on our rootstock mapping population. Hopefully we don’t make 150 nasty shots of Marquette, a few smelled a bit past prime….

Spontaneous dry-on-vine is a newer trait being pursued by #raisin #grape breeders as it offers considerable labor savings compared to other varieties whose grapes must be separated from the vine to dry

After 20+ years of evaluation, @UMNHorticulture will this year release its 6th cold-hardy winegrape variety, to be called Clarion. Formerly MN 1220, it's a white variety suited to Zone 5 climates like IA and WI. #graperesearch https://t.co/HhPXQs1rva
