# Pasteur reports heating wine as a method to prevent diseases of wine for imperial industrial use

Date: 1865

## The fact

In 1865 [Louis Pasteur](/people/louis-pasteur) reported practical results of heating wine to temperatures that checked the microbial diseases of wine without ruining the product as a drink, work commissioned in the early 1860s for French viticulture. It is not a 1880s milk statute in another country, and it is not the 1881 anthrax trial. Beer studies after 1870 are a later book.

## Context

French export wine was spoiling in barrels. The imperial government asked a chemist already famous for fermentation to rescue a fiscal and prestige product. Heating is an industrial control, not a vaccine. Small cellars without apparatus faced a different cost, stored on a worsening row. Assistants and local vignerons ran trials. Sharing labour does not erase Pasteur’s signed reports to the Academy and to ministers. Later uses on milk, beer, and other liquids are other people’s statutes and other Facts.

Shared responsibility is part of Pasteur reports heating wine as a method to prevent diseases of wine for imperial industrial use. Naming Louis Pasteur does not delete co-authors, institutions, or later transmitters. The lag from 1865-04-20 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

## Evidence and sources

The Académie des sciences at https://www.academie-sciences.fr/ is the official learned-society home of the Comptes rendus in which Pasteur’s wine communications were lodged. Britannica’s pasteurization article at https://www.britannica.com/science/pasteurization independently describes the wine-heating origin and later dairy extension without making Pasteur the signer of every twentieth-century milk ordinance.

## Significance

Public-health and food-safety path via spoilage control. Modest-to-mid weight: wine is not a national water system. High confidence on the 1860s wine work.

## What is established and what is not

Established: Pasteur reported heating wine against microbial spoilage in the mid-1860s. Not established: that he wrote a universal milk law, or that every later pasteurizer is this report. Contribution is recorded as He designed the heating trials and reported them. Napoleon III’s officials commissioned wine work; vignerons and unnamed cellar workers applied heat. Complex. The impact note is Controlled heating of wine to stop microbial spoilage is a food-safety instrument with a public-health path, not yet a municipal milk law. The dated heading stays Pasteur reports heating wine as a method to prevent diseases of wine for imperial industrial use on 1865-04-20, not a later statue, UNESCO listing, or school film. Printers, unnamed clerks, and later editors may appear in the same file without becoming this instrument.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

If a number is not in the two records named above, it is not supplied here.

Confidence is stated on the impact path, not hidden in adjectives. Wine heat is not milk law and not a later museum of food. Mixed effects of Pasteur reports heating wine as a method to prevent diseases of wine for imperial industrial use are separate paths.

The attached driver is health-system-capacity. The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.
