Lead itself, as a metal, is reported to have a somewhat metallic, astringent, and not very interesting taste. However, certain lead compounds, especially lead acetate (known historically as "sugar of lead"), are noted for their sweet taste. Lead acetate tastes sweet but not like regular sugar; it is described as having an artificial, chemical sweetness somewhat like Splenda rather than table sugar or honey. This compound was historically used as a sweetener, notably in ancient Roman times to sweeten wine. The metallic taste is not generally attributed to lead acetate, but to other metallic tastes sometimes associated with lead exposure. Some people also report a tingling sensation and a bit of fruity or acetic taste with lead compounds. Lead itself does not have a smell because it does not vaporize, but lead acetate has a faint acetic (vinegar-like) chemical odor. In summary:

• Metallic lead tastes metallic and astringent.
• Lead acetate tastes sweet, artificial, and somewhat fruity or chemical, unlike typical sugar.
• Lead compounds can have subtle sensory effects but are toxic and not recommended for tasting.
