Is Your Lake County or Mendocino Vineyard Covered for Smoke Taint in 2026?
Is Your Lake County or Mendocino Vineyard Covered for Smoke Taint in 2026?
Wildfire smoke is no longer a rare event for California wine grape growers — it is an annual risk that must be actively managed. For vineyards in Lake County and Mendocino County, the question is not whether smoke will affect your operation in any given season, but whether your insurance policy is structured to respond when it does.
The Fire Insurance Protection-Smoke Index (FIP-SI) endorsement, available as an add-on to a base Multi-Peril Crop Insurance (MPCI) policy, is the only federally backed coverage product specifically designed to address smoke taint damage to wine grapes. Here is what Lake County and Mendocino growers need to know heading into the 2026 growing season.
How FIP-SI Works
FIP-SI pays an indemnity when two conditions are met: a qualifying smoke event occurs during the insurable period (typically bud break through harvest), and your grapes test positive for smoke taint volatile phenol compounds above the insurable threshold established by the RMA.
The coverage is triggered by a combination of the Smoke Index — a measure of smoke exposure calculated using satellite and weather data — and laboratory testing of your harvested fruit. If both thresholds are met, your policy pays based on the difference between your insured value and your actual revenue from the affected crop.
Why Lake County and Mendocino Are High-Priority Counties
Lake County has experienced significant wildfire activity in recent years, including the Valley Fire, the Ranch Fire, and multiple smaller events that have produced sustained smoke exposure during critical growing periods. Mendocino County faces similar exposure, particularly in the inland appellations of Redwood Valley, Potter Valley, and the upper reaches of the Anderson Valley.
For growers in these counties, FIP-SI is not a supplemental product — it is a core component of a complete risk management strategy. Without it, a smoke event that renders your fruit unsalable or significantly reduces its value will not be covered by your base MPCI policy.
What FIP-SI Does Not Cover
It is equally important to understand the limitations of FIP-SI coverage. The endorsement does not cover:
- Smoke events that occur outside the insurable period
- Smoke taint below the RMA-established threshold
- Revenue losses from market price declines unrelated to smoke
- Grapes that were not enrolled in the base MPCI policy
This is why proper policy structure matters. FIP-SI must be attached to a correctly structured base MPCI policy, with the right coverage level and the correct unit structure, to provide meaningful protection. A policy that looks complete on paper but has structural gaps can leave you exposed when a claim is filed.
