Ethanol
The ethanol made from plant material is slightly radioactive. This is because plants are continually absorbing carbon-14, (14C), until they die. Carbon-14 is radioactive and has a half life of around 5,730 years. Before you panic, you are also absorbing carbon-14 from the environment, even when you’re breathing.
As a chemist I know that ethanol produced from plant material and that produced in the lab is the same chemical but when it comes to drinking a glass of wine, I’ll take the stuff made from grapes. Chemists are yet to synthesise red wine in the laboratory.
