Welcome to Under the Hood, our exclusive weekly series for Napa Valley Features paid subscribers.

Summary of Today’s Article: Two trustee’s sale notices recorded against Signorello Estate on July 27 put a Napa winery, its vineyards and its brands on the auction calendar for Aug. 21, with estimated unpaid balances exceeding $37 million. It is the most visible production-side default of this downturn, and it is also the exception — the version of contraction that leaves a public record. Over the same period, Napa County’s active winery license count peaked at 1,934 on June 10, 2025 and has fallen since, reversing a measure that had risen for at least a decade. That decline is not businesses failing. Setting aside the annual renewal purges, the rate at which new licenses appear fell 96% in Napa, from 1.84 a week to 0.07, while California’s fell 66%, from 4.87 to 1.65.

Beyond today’s discussion, we’re also digging into the latest results from our reader polls and pulling a few takeaways from our local economic dashboard.
