On 15 June 2016, in Lyon, a working group of 23 scientists convened by the International Agency for Research on Cancer (IARC), the World Health Organization’s cancer agency, closed a chapter that had lived in consumers’ heads for a quarter of a century. Coffee, classified in 1991 as possibly carcinogenic to humans (Group 2B), moved to Group 3: not classifiable as to its carcinogenicity. The summary appeared that day in *The Lancet Oncology*; the full assessment became Volume 116 of the Monographs. PAHO carried the finding for the Americas.
The scale of the review matters because it dismantles a myth with method, not with a slogan. The group examined more than a thousand studies in humans and animals. Overall evidence on whether drinking coffee causes cancer was judged inadequate. For pancreas, female breast and prostate, many epidemiological studies showed no carcinogenic effect. For liver and uterine endometrium, reduced risks were seen. For more than twenty other cancers, the data could not support a conclusion. That is not a certificate of absolute safety: IARC itself notes that Group 3 does not prove a substance is “safe”; it means available science cannot conclude that it causes cancer.
What was reclassified: heat, not the bean
The same evaluation reserved a different warning for very hot beverages, placed in Group 2A (probably carcinogenic to humans), with limited evidence of a link to oesophageal cancer. The issue, the experts said, is extreme temperature, not coffee, maté or another infusion as such. A grower or a roaster cannot “cure” anything with a lot: coffee is not a drug. To say that “coffee cures cancer” would distort the report. The honest reading is more modest and more useful: the cup no longer carries the 1991 stigma, and whoever pours it should avoid the boil that scalds the tongue.
For readers of a small origin, the cultural nuance is as important as the clinical one. Highland Salvadoran coffee — Pacamara, Bourbon, Gesha — is drunk because the cherry ripens slowly on a volcanic mountain and delivers sweetness and clean acidity, not because it claims to be a treatment. That cup is tasted warm, compared, explained. It fits the 2016 reading: a quality food that can be enjoyed without the fear inherited from an old label, and without turning it into a miracle.
A mountain cup, not a medicine
Anyone who discovers Café de El Salvador after that reclassification meets a country that sells landscape and craft: shade, ripe cherry, disciplined process. Washed Bourbon often shows panela and citrus without aggression; Pacamara, flower and fruit with body; Gesha, a floral clarity that asks for a roast that does not cover the origin. None of that replaces a physician. All of it does explain why it is worth choosing a farm arabica over an anonymous drink served at soldering temperature.
The teaching fits in a bar sentence: enjoy coffee for what it is — flavour, origin, ritual — and let it cool a few degrees. The science of 2016 did not canonise the cup; it removed a stain and pointed at extreme heat. Coffee from El Salvador’s ranges fits there naturally: it is grown to shine in the cup, not to occupy a pharmacy shelf.
