If the germ theory is relatively new, how do they think fermentation was happening (like wine, ale, yogurt etc.) thousands of years ago?
In: 613
Most medieval and before cultures didn’t really know why a lot of things happened, they just knew that they did happen. Call it a blessing from God(s). They essentially found out that the process we know to be fermentation happened under certain conditions and then that knowledge was passed on down the generations. Its pretty crazy to think that until maybe 300 years ago we didn’t really know why anything happened, just that it did.
