  • The West Coast of the United States produces over 90 percent of America's wine, an alcoholic drink.
  • 2
  • However, the area is also prone to wildfires.
  • 3
  • Such fires cost the American wine industry billions of dollars in 2020.
  • 4
  • The smoke affects the flavor of the growing grapes that later become the wine.
  • 5
  • And, the flavor is undesirable, say some wine drinkers.
  • 6
  • So, wine experts from state universities in the area are working together to protect wine grapes from wildfire smoke.
  • 7
  • In 2020, economists say, wildfires caused billions of dollars of losses, which included the wine industry.
  • 8
  • As a result, the U.S. Department of Agriculture is paying for grape research at some state schools.
  • 9
  • They include University of California, Davis (UC Davis), Oregon State University and Washington State University.
  • 10
  • The research investment is worthy, agriculture officials say, because wine grapes are America's highest-value crop.
  • 11
  • Tom Collins is a wine scientist at Washington State.
  • 12
  • He said "the ability to continue to make wine" is at risk in areas where smoke might be more common.
  • 13
  • Cole Cerrato is a researcher working on the problem in Oregon.
  • 14
  • He stood in Oregon State's vineyard, near the small town of Alpine.
  • 15
  • He lit a fire and blew the smoke through a hose and into a row of grapes covered in plastic.
  • 16
  • Cerrato and other researchers have done this before.
  • 17
  • They turned the treated grapes into wine.
  • 18
  • The result was, the wine had an unpleasant flavor of smoke and ash.
  • 19
  • The scientists are working to find a way to keep the smoke from getting through the grape skins and creating a bad taste in the wine.
  • 20
  • Some are trying to create a process that will treat wine and remove the smokiness.
  • 21
  • But they are concerned such a process might remove some of the wine's good flavors, too.
  • 22
  • Others think they can combine smoke-affected grapes with other grapes.
  • 23
  • The mix might lessen the smoky flavor.
  • 24
  • And Collins is working on a spray made from water and a kind of clay that would protect the grapes from smoke.
  • 25
  • But all the grapes would need to be washed first before being turned into wine.
  • 26
  • Oregon State is experimenting with a similar spray treatment for grapes.
  • 27
  • In addition, the USDA has provided $7 million toward setting up smoke sensors in vineyards.
  • 28
  • Anita Oberholster is leading the efforts to save the wine grapes at UC Davis.
  • 29
  • In an internet post by UC Davis, she said a network of sensors would help grape growers learn if their grapes are at risk.
  • 30
  • In addition, the readings from the sensors will permit the growers to prove their grapes are free from smoke damage.
  • 31
  • Winemakers are glad that the universities are working to help the industry.
  • 32
  • Greg Jones runs the Abacela winery in southern Oregon and is the director of the state's winemaking trade group.
  • 33
  • He said the research has "gone a long way."
  • 34
  • Now the grape-growers can quickly find out if the fruit has been hurt by the smoke.
  • 35
  • In the past, winemakers would not know about the wine until it was ready to drink.
  • 36
  • "I think it's increasingly clear that we're not likely to find a magic bullet," Collins said.
  • 37
  • But, he said, the researchers will find ways to keep the wine business successful.
  • 38
  • I'm Dan Friedell.
