The beer brewing and the technical inventions.

Brasserie et inventiosn techniques

 

The mythical beer is said to have originated from a few seeds thrown into a hole filled with water, a risky porridge metamorphosed into a delicious beer by the sun's rays. A Chinese legend tells this story (Grand Khan). Men and monkeys are the actors!

Beer, in other words the brewery, does not exist without the ingenious help of humans.

 

The history of the brewery is a long line of technical innovations. As early as the Neolithic period, the brewery has been constantly adapting to the changing nature of economics and social organisations. Contrary to popular belief, the brewery has been innovating since its birth. No brewery without intelligent grain management. No beer can be brewed without at least a minimum mastery of technology, which does not presuppose any scientific knowledge.

The early beer brewing emerges with the following basic techniques:

  • Containers: wooden troughs / earthenware
  • Cooking (optional): fire, heating devices, fireproof terra cotta
  • Sieves/filters (optional): wickerwork, weaving

The rudimentary nature of this technological base should come as no surprise. The brewery is first and foremost a biotechnology. Vats, pots and ladles count less than the decomposition of starch. A cold brewing process can be carried out in wooden troughs. The pottery is needed for brewing purposes in the form of grain storage jars or primitive silos.

From the Neolithic period onwards, the main technical leaps are shown in the table below that does not include :

  • the many different material devices invented over thousands of years.
  • the old or modern types of beers
  • the innumerable third-party techniques applied in brewing since the 19th century: sterilisation (physical or chemical), genetics, enzymology, industrial automation, computers, etc.

Recycling of the dregs, wet or dried spent grains to feed animals.

Mesopotamia

-2000

Brew control by ratios: vol. grains/vol. beer (paleo-babylonian) or vol. grain + vol. dates/vol. beer (Egyptian)

Mesopotamia

Egypt

-1000 (?)

Invention of amylolytic ferments.

Bohemia, Bavaria

Around 1715

Temperature control during the malting / brewing steps with a thermometer (Fahrenheit/Combrune).

France

1843

Control of yield (saccharification) and apparent attenuation (alcoholic fermentation) with the densimeter (Carl Balling)

Bohemia (Prague)

1871

Bacteriological protection of the wort to be fermented (Pasteur)
