2020 losses from wildfires estimated at $3.7 billion

CORVALLIS, Ore. (KTVZ) – Oregon State University researchers and a team of West Coast university collaborators have received a $7.65 million grant to study the impact of smoke exposure on grapes, a project the school said will provide critical knowledge to grape growers and winery owners severely impacted by widespread wildfire smoke in recent years.

Oregon State researchers will work with scientists at Washington State University and the University of California, Davis, on the four-year project, which is funded by the U.S. Department of Agriculture’s National Institute of Food and Agriculture.

“Smoke events are only likely to increase, and last year made it clear we need to be better prepared,” said Elizabeth Tomasino, associate professor of enology at Oregon State and lead researcher on the grant. “This research will go a long way in providing tools that will allow the grape and wine industries to quickly make decisions that significantly impact their economic livelihoods.”

The grape and wine industry contributes $220 billion to the U.S. economy, and wine grapes are the highest value fruit crop in the country, according to WineAmerica, a group that represents the wine industry in Washington, D.C.

Wildfires are a significant threat to these industries because persistent exposure to smoke compromises the quality and value of wine grapes and adversely affects wines. That threat is particularly pronounced on the West Coast of the United States, where California, Oregon and Washington are three of the nation’s top four wine-producing states.

An economic analysis of the 2020 wildfires estimated losses up to $3.7 billion, a number that will be felt into 2023 because many wineries have decided to not produce wine from 2020 grapes due to the severity of impacts from wildfires.

In the wake of the challenging 2020 vintage, the grape and wine industry on the West Coast want to better understand how smoke density and composition impact grapes, grape vines, wine composition and sensory perception of the wine in a glass. The research team is calling this a “smoke to glass” understanding.

With the grant, the team seeks to:

  • Develop new technologies and establish low-cost sensors and sensor networks for real-time risk assessment in the vineyard.
  • Assess the impact of smoke exposure on the health of grapes and grapevines.
  • Develop grape coatings to reduce or eliminate uptake of smoke components into grapes.
  • Optimize a rapid small-batch fermentation method to predict what a wine impacted by smoke will taste like when fermented on a commercial scale.
  • Determine sensory quality thresholds of smoke compounds in wine.
  • Link environmental, chemical and sensory data to create predictive modeling of smoke risk to grape and wine quality.
  • Create an integrated outreach component to communicate the research findings and their use, and enable industry to benefit from them.

The grant builds on other recent smoke taint research efforts at Oregon State.

Last fall, researchers, including Tomasino and other members of the Oregon Wine Research Institute, which is housed at Oregon State, quickly mobilized to process more than 600 grape samples and 800 wine samples from Oregon growers and used gas chromatography mass spectrometers to analyze the types and levels of smoke compounds in them.

In June, the Oregon Legislature approved $2.6 million to fund an Oregon State testing lab to assess the impact of wildfire smoke on wine grapes, orchard fruit and other crops.

The work planned with the new grant builds on previous research by the same team made possible by funding from the American Vineyard Foundation, Northwest Center for Small Fruits Research and the USDA’s National Institute of Food and Agriculture.

Other Oregon State researchers involved with the new project are: Alec Levin, James Sterns, Yanyun Zhao and James Osborne, all of whom are part of the College of Agricultural Sciences or Oregon State University Extension Service.

  1. So, your tax dollars (7.65 million of them) have gone to a study that will tell you that grapes grown during Smokey periods of time will taste different? Climate change is ruining wine! Now I know why they call it a crisis.
    Can we spend a few mil to study what pigs eat that make hot dogs taste so good?

  2. From the article, “Develop grape coatings to reduce or eliminate uptake of smoke components into grapes.”.

    Put that coating on your grapes and I will not buy your wine.

  3. Stupid waste just like all the dumbos in Wash. DC including our President who is hell bent on destroying America. Wait till we get the bill for climate change promoted by the biggest polluters like Kerry, Gore and the rest flying around the world poking you in the eye. China and Russia are saying go for it we ain’t doing a damn thing we are going to beef up our military.
