Steam engine 1765
With the introduction of James Watt´s steam engine, industrialization and
rationalization began to invade brewing. The first breweries to use steam power
called themselves Steam Beer Breweries. Today, one brewery in German
still uses the name steam beer.
The first German railway line was opened between Nürnberg and Fürth. The first
goods transported were (otherwise we wouldn't have mentioned it here) two
barrels of beer.
Industrial developments did not simply pass over the beer brewers but started
to take their effect at the beginning of the 19th century. Two extremely
important inventions revolutionized beer brewing. The first, as previously
mentioned, was James Watt's steam engine which dramatically increased the
efficiency of the breweries. The second, even more important to the brewing
industry, invention was by
In von Linde's time , it had already been scientifically proven that the
making of good beer required certain temperatures. The brewing of bottom
fermented beer (lager beer), for example, demands temperatures of 4 to 10
degrees Centigrade. Such temperatures occur only in winter, or in deep cellars
with the use of large quantities of block ice. Through the invention of
refrigeration by Carl von Linde, beer brewing became seasonally independent.
Fittingly, the first refrigeration equipment was tested in a Munich brewery.
Considerable scientific research took place in breweries in the 19th century. A
famous work from 1876 by Louis Pasteur was "Etudes sur la Biere"
(studies concerning beer). Louis Pasteur gained his knowledge of microorganisms
from these studies. This basic knowledge is still indispensable today, not only
in the production of beverages, but also in medicine and biology. (Everyone
knows the word "pasteurized" from the milk cartons in the
supermarket.) We owe our knowledge, that the beer witches were the victims of
unsanitary work procedures and sloppy brewers, to Louis Pasteur. Another
pioneering discovery in beer brewing was the work of
The Danish scientist, Christian Hansen, successfully isolated a single yeast
cell and induced it to reproduce on an artificial culture medium. With the
ensuing yeast propagation methods, the purity of the fermenting process has been
improved and beer taste perfected.
Beer and its price have always been of extreme importance to German consumers.
The consequences a beer price increase can bring with it were shown in 1888 in
Munich when the Salvator battle took place, as citizens violently rebelled
against such a price increase.
Wooden barrels have been almost completely replaced by metal barrels for
most pub trade. In 1964 metal kegs were introduced in Germany. Firstly, cleaning
and filling was much simpler. Secondly, tapping and closing off was much easier
for the bar personnel. This was a big hit with pub and restaurant owners. Kegs
are cylindrical, made of stainless steel or aluminum and contain an extractor
tube. Some compressed carbon dioxide remains in the keg after closing off to
prevent the beer residue from drying out.
Although our "Beer History" has come to an end here, thousands of
German brewers and millions of fans of German beer around the world write new
chapters every day.
