Napoleon III sent Louis Pasteur to study wine spoilage

The problem incurred heavy economic losses to the French wine industry and became a matter of state. It was Emperor Napoleon III himself who asked Pasteur for help. With great ardor Pasteur began his investigation, making a city of Arbois, in his native Jura department, a theater of the experiments.

One aspect that characterized Pasteur's career was that he was approached to solve quite specific problems in a variety of different fields. In 1863, Napoleon III asked him to study diseases in wine. Wines were turning sour, and this was a major problem because a treaty had just been signed ...

Pasteur's direct work on pasteurization began in earnest around 1864, when he investigated the spoilage of wine at the request of Napoleon III.

In 1863, Louis Pasteur (1822-1895) was commissioned by Emperor Napoleon III of France (1808-1873) to research the conditions under which wine is converted to vinegar. The result of this work was incorporated into this volume, which recapitulates Pasteur’s landmark study of fermentation in wine and the development of micro-organisms; Pasteur proved that alcohol in wine is oxidized via...

His ideas of fermentation and experiments on milk and wine spoilage indicated disease by microorganisms. Prior to Pasteur, the connection between microorganisms and disease was not apparent, since many microbes were known to be beneficial and ...

Around this same time, at the behest of Emperor Napoleon III to save the French wine industry, Pasteur curated his heating and cooling process, saving the wine from souring while preserving its original flavor by heating it to a meager 122°-140°F.

In 1863, at the request of Napoleon III, he turned his attention to wine. After a long process of inspecting the wineries in France’s various regions, Pasteur had this to say: “There may not be a single winery in France, whether rich or poor, where some portions of the wine have not suffered greater or lesser alteration.” In short, it was looking bad. Thanks to his work with fermentation and bacteria, though, Pasteur knew that it was microorganisms causing the spoilage.

At about this time, Emperor Napoleon III commissioned Pasteur to save the entire French wine industry, which had become overrun by “diseases” that caused the wine to be sour or bitter.
