In cellar technology, Hermann Müller-Thurgau explored the possible control of the alcoholic fermentation, the biological degradation of acids (he correctly recognized bacteria as the cause of the malolactic fermentation ) as well as malformations in fermentation and maturation of the wine. He also bred Gärhefestämme with special properties and dealt with methods for the production of non-alcoholic grape juices and for the production of fruit juices. Müller is regarded worldwide as a pioneer in the field of the unfermented pasteurized Fruit juices. His most important publications include noble rot of grapes (1887), The production of unfermented and non-alcoholic fruit and grape wines (1896), The red burner of the vine (1903) and bacteria in wine (1913).
