Louis Pasteur (1822-1895)  invented the process of pasteurization. Pasteurization has become synonymous with dairy products, but Louis Pasteur made his most famous discovery studying the fermentation and the souring of beer and wine. Pasteur proved that microorganisms in liquids like beer and wine were the cause of spoilage, fermentation, and disease. 

Pasteur discovered that the growth of microorganisms could be prevented in the process of boiling liquids and later cooling them. This process was later named after Pasteur “pasteurization”. He discovered the pasteurization process in 1862 thanks to his studies on alcohol. The pasteurization process revolutionized the beer, wine, and silk industries in France, making this world a little bit safer for all of us – thanks to alcohol studies.
