In ancient Rome, grape syrup was often boiled in lead pots, which sweetened the syrup through the leaching of the sweet-tasting chemical compound lead acetate into the syrup. Incidentally, this is thought to have caused lead poisoning for Romans consuming the syrup.[13][14] A 2009 History Channel documentary produced a batch of historically accurate defrutum in lead-lined vessels and tested the liquid, finding a lead level of 29,000 parts per billion (ppb), which is 2,900 times higher than contemporary American drinking water limit of 10 ppb. These levels are easily high enough to cause either acute lead toxicity if consumed in large amounts or chronic lead poisoning when consumed in smaller quantities over a longer period of time (as defrutum was typically used).[14]
