PASTEURIZATION METHOD
Some of his contemporaries, including the German chemist Justus Von Liebig, insisted that fermentation was a chemical process and did not require the intervention of any organism.

One produced alcohol and the other lactic acid, which made the wine sour. In 1864, Louis Pasteur invented his own pasteurization method. -
