Études sur la bière, ses maladies, causes qui les provoquent, procédé pour la rendre inaltérable, avec une théorie nouvelle de la fermentation

First edition of this major work, illustrated with 12 engraved plates and 85 figures in the text (cf. Garrison-Morton 2485. Osler 1550. Duveen 461. Cushing P/139. Waller 10966. Norman 1658).

In studying the process of fermentation, Pasteur demonstrated that the spoilage of beer was caused by airborne microorganisms, and not by spontaneous generation as previously believed.

His research contributed significantly to the treatment and preservation of perishable beverages such as beer, wine, and milk.

A very attractive copy, preserved in its original wrappers.
