Linguistic Origin & Historical Etymology

Derived from the Late Latin word 'torrefactio', stemming from the verb 'torrefacere' (to dry by fire, roast), combining 'torrere' (to parch or burn) and 'facere' (to make). Entering technical English usage in the 17th century, it initially described the metallurgical roasting of ores and pharmaceutical parching of drugs before expanding to modern thermal biomass processing.
