Enzymatic hydrolysis revealed substantial bound guaiacol and methylguaiacol in smoke-exposed fruit, sometimes despite low free concentrations. The chapter combines the 2008 wildfire geography, exposure observations and grape analyses to assess smoke-related aroma risk.

Usage map
Observational association is not an isolated causal dose-response. Do not use a single marker concentration as a universal sensory cutoff, or convert historical air-quality information into current advice.
Verification checklist
Fresh September 28 qualification
PDF76 compares bound precursor with a free-odorant threshold, which cannot establish direct aroma activity. Methods/results cultivar descriptions also differ; county particulate exposure is not a vineyard-specific molecular dose.
