Beta-caryophyllene is one of the most volatile terpenes found in cannabis, so easily airborne that it can breach through plastic containers. It is the terpene that drug-sniffing dogs are trained to detect because it is always present in the air around cannabis. Its presence in rosin testing indicates minimal terpene destruction during the pressing process.
// From the Episode
Tony Verzura highlights in Ep 028 that Jeff's rosin testing showed caryophyllene was still present despite heat exposure during pressing. He argues this is significant because caryophyllene is extremely volatile and caustic, so its survival in rosin proves that the brief pressing time preserves even the most fragile terpenes. Mark Scialdone confirms these molecules will rearrange in any heated, oxygen-rich environment.
