Pickett Fire inflicts $65 million in damages on Napa wine industry as smoke taint threatens grape harvest

The Pickett Fire in Napa County has caused an estimated $65 million in damages, according to early figures released by the Napa County Agricultural Commissioner. The majority of this loss is concentrated in the region’s wine industry, which is still assessing the full extent of the impact as fire crews continue to contain the blaze.

The fire affected approximately 1,500 acres of crops, with grapevines bearing the brunt of the damage. Of the grapes impacted, officials estimate that 20 percent suffered direct harm from fire and heat, while 80 percent were damaged by smoke exposure alone. Tracy Cleveland, Napa County Agricultural Commissioner, emphasized that these numbers are preliminary and subject to change as more information becomes available from growers and producers in the coming weeks.

Bruce Regalia, a winemaker with over three decades of experience, described the challenges that smoke poses to grape quality. He explained that smoke compounds can penetrate grape skins and create unpleasant flavors in wine. “It infiltrates the grape through the skin, and it makes a compound that is not pleasant to taste,” Regalia said. He recalled previous years when heavy smoke forced some vineyards to forgo harvesting altogether due to concerns about wine quality.

Regalia’s own Wild Diamond Vineyards is located north of the Pickett Fire’s path and may avoid significant damage this year. However, he noted that even small amounts of smoke can affect grapes and that testing is required to determine if fruit is suitable for winemaking. This process involves either laboratory analysis or producing small test batches during fermentation, as tasting grapes directly from the vine does not reveal potential smoke taint.

The recent increase in wildfire frequency across California has prompted the wine industry to seek new solutions for mitigating smoke damage. Researchers and winemakers are experimenting with filtration techniques and other methods to reduce or eliminate smoky flavors from affected wines. Despite these efforts, Regalia said he has yet to encounter a method that fully restores wine quality after significant smoke exposure.

As recovery efforts continue, Napa’s wine community faces uncertainty about this year’s harvest and long-term effects on production. The Agricultural Commissioner’s office will continue working with local growers and vintners to assess losses and support recovery initiatives as more data becomes available.
