You may not have heard of zymology, but you have most certainly seen the results of its research. Zymology is the study of how sugar, yeast and water transform into alcohol. While that may sound like something that college fraternities have been researching informally for years, it is actually a real and rigorous branch of science. The first zymologist was Louis Pasteur, inventor of the vaccine. It was he who discovered the link between yeast and fermentation. Eduard Buchner, the 1907 Nobel Prize winner in chemistry, was also a zymologist, who further illuminated the biological processes of fermentation. In fact, the search for a better understanding of beer laid the foundation for what later became known as molecular biology.
