The Romans had a sweetener called Sapa, made from grape juice left in lead vats. The Romans loved putting it in everything. Lead poisoning... It dooms the wealthy and nobility...


Grape syrup was known by different names in Ancient Roman cuisine depending on the boiling procedure. Defrutum, carenum, and sapa were reductions of must. They were made by boiling down grape juice or must in large kettles until it had been reduced to two-thirds of the original volume, carenum; half the original volume, defrutum; or one-third, sapa. The Greek name for this variant of grape syrup was siraion (σίραιον).[6]

The main culinary use of defrutum was to help preserve and sweeten wine, but it was also added to fruit and meat dishes as a sweetening and souring agent and even given to food animals such as ducks and suckling pigs to improve the taste of their flesh. Defrutum was mixed with garum to make the popular condiment oenogarum. Quince and melon were preserved in defrutum and honey through the winter, and some Roman women used defrutum or sapa as a cosmetic. Defrutum was often used as a food preservative in provisions for Roman troops.

Sapa was produced by boiling unfermented grape juice in order to concentrate the natural sugars. The juice was reduced to a third of its original volume. When the juice was boiled in lead alloy kettles, this harmful element seeped into the drink. The ancient Romans used Sapa as a form of artificial sweetener, especially in wine. They eventually found a way to convert lead sugar into a crystalline form.



A new study shows that extremely high levels of lead have been found in the bones of 30 people who lived in Londinium (today’s London) during the 1st to 3rd centuries AD. The U.S. Institute for Occupational Health and Safety states that 5 micrograms of lead per deciliter of adult blood indicates that the blood has become toxic – the researchers found an average of 14.4 micrograms of lead per deciliter of blood in the thigh bones they studied.

Forbes says that the findings suggest “more than half of the population” in Roman-era London were dealing with issues caused by lead poisoning. Could it have come from the metal in their weapons, pipes, or jewelry? Or maybe the lead was directly ingested…

It may not have been the lead(II) acetate, but rather the concentration of glucose and fructose from the grape juice, that gave the syrup its sweetness. It was perhaps the extra sweetness that the compound gave to the syrup that drew the attention of the Romans.

According to one source, the discovery of lead(II) acetate as a sweetener was an accident. As they were trying to make their products sweeter, Roman winemakers were experimenting with various ingredients and preparation techniques. At some point of time, they tried boiling the leftover unfermented grape juice in lead kettles. When the entrepreneurial winemakers noticed that this procedure produced the sweetest syrup, they decided to begin making this substance in large amounts.

Roman lead pipe theories...


Many people seem to have the impression that everyone in ancient Rome suffered from lead poisoning because the Romans used pipes made of lead. Indeed, many people seem to think that this was a major contributing factor in the decline of the Roman Empire. This idea is largely inaccurate, but there is some truth behind it.
