Wildfire Smoke and Wine Grapes: How FIP-SI Protects California Vineyards
Wildfire Smoke and Wine Grapes: How FIP-SI Protects California Vineyards
Wildfire smoke has become one of the most significant and underinsured risks facing California wine grape growers. In Sonoma, Napa, Mendocino, and Lake counties, smoke events during the critical ripening window can cause smoke taint — a condition where volatile phenols from smoke penetrate grape skins and bind to sugars, producing off-flavors that make the fruit unmarketable. The financial damage can be catastrophic.
The good news is that federal crop insurance now provides a specific tool to address this risk: the Fire Insurance Protection-Smoke Index (FIP-SI) endorsement. At Advantage Crop Insurance Agency, we help California wine grape growers understand, access, and maximize this coverage.
What Is the FIP-SI Endorsement?
The FIP-SI endorsement is an add-on to your standard Multi-Peril Crop Insurance (MPCI) policy. It provides coverage for yield losses caused by smoke exposure from wildfires. Unlike standard MPCI, which requires you to demonstrate an actual yield loss, FIP-SI uses a smoke index — a measurement of smoke density and duration during the growing season — to trigger coverage.
This is a critical distinction. Smoke taint damage is notoriously difficult to quantify at harvest. Grapes may look healthy but be chemically compromised. The FIP-SI endorsement removes the burden of proving individual vine-level damage by tying the claim trigger to an objective, measurable index.
Who Needs FIP-SI Coverage?
Any wine grape grower in a county with a documented history of wildfire smoke events should consider FIP-SI. This includes virtually all growers in:
- Sonoma County: The Kincade Fire (2019) and Walbridge Fire (2020) caused widespread smoke exposure across the county’s premier appellations.
- Napa County: The Glass Fire (2020) and LNU Lightning Complex (2020) directly threatened vineyard operations throughout Napa Valley.
- Mendocino County: The Mendocino Complex Fire (2018) remains one of the largest in California history, with smoke impacts extending across multiple growing seasons.
- Lake County: Consistently among the highest-risk counties in California for wildfire activity, with multiple major fires in recent years.
How FIP-SI Works with Your MPCI Policy
FIP-SI is an endorsement, meaning it attaches to your underlying MPCI policy. You must already have MPCI coverage for wine grapes to add FIP-SI. The endorsement is available through the USDA Risk Management Agency (RMA) and is sold through licensed crop insurance agents like Advantage Crop Insurance Agency.
The smoke index is calculated using data from monitoring stations and satellite imagery. If the index exceeds the threshold during your policy period, a claim can be filed regardless of whether you can visually identify damage at the time of the event.
Sign-Up Deadlines and Timing
FIP-SI must be added to your MPCI policy before the sales closing date — typically in late winter for California wine grapes. You cannot add the endorsement after a smoke event has occurred. This is one of the most common and costly mistakes we see: growers who experience a smoke event and then try to add coverage after the fact.
If you are reading this after a fire season and do not have FIP-SI, the time to act is now — before the next sales closing date.
