Smoke Exposure Research Act of 2025

This bill directs the U.S. Department of Agriculture’s research arm to study how wildfire smoke affects wine grapes and wine. It calls for finding the smoke compounds that cause problems, creating fast and inexpensive testing methods, building a database of normal background levels in grapes, and developing tools to judge risk and reduce damage. It also asks researchers to look for coatings or other barriers that can protect grapes from smoke. The work must be done with land‑grant universities in California, Oregon, and Washington that already study grape growing and winemaking in smoky conditions .

The bill authorizes $6.5 million per year for 2026 through 2030 for this research, with funds available until used.

• Who is affected: Wine grape growers, wineries, and university researchers in CA, OR, and WA .
• What changes: Federal research will create standard smoke testing methods, a background-levels database, risk tools, and possible protective treatments for grapes.
• When: Funding is planned for fiscal years 2026–2030.
