Smoke impact is an increasingly important issue in the wine world, but it's very difficult to test for

Smoke damage from wildfires is becoming an increasingly significant problem for vineyards across France, Spain and Portugal, but producers face a major challenge: there's no reliable, standardised way to test whether their grapes and wine have been affected by smoke taint. This matters because smoke can spoil wine flavour at very low levels, yet detection remains difficult and inconsistent, leaving growers uncertain about their harvest quality and saleability.
