Pasteur showed that otherwise identical molecules could exist as mirror images (or ‘left’ and ‘right-handed’ versions.) He noticed that molecules produced by living things were always left-handed which lead to being the foundation stone for microbiology.

For numerous years, people thought life appeared spontaneously, that fleas grew from dust, or maggots from dead flesh. Pasteur finally disproved this theory and showed that food went off because of contamination by micron in the air. He went on to argue that these could cause disease. This also lead to his “germ theory”.

All over the Europe the biggest problem was how to save the wine, when Pasteur realised this was due to contamination. He noticed that boiling wine to kill bacteria made it taste terrible. In a series of experiments, Pasteur discovered that heating wine to 55 degrees killed bacteria without ruining the taste. This process, later named as pasteurisation, saved the wine industry. Today, it’s widely used to keep food free from disease.

He once said, “A bottle of wine contains more philosophy than all the books in the world.”
