The earliest humans discover by chance that grain that has become damp can ferment into an alcoholic drink.
The Sumerians develop one of the first written beer recipes and celebrate beer in the Hymn to Ninkasi.
The Egyptians elevate beer brewing to an advanced craft and use it as a means of payment and offering to the gods.
Medieval monks refine brewing techniques and lay the foundation for systematic and quality beer brewing in Europe.
The introduction of hops into the brewing process drastically changes the taste and shelf life of beer.
Duke William IV of Bavaria issues the famous German Reinheitsgebot, decreeing that beer may only be made from water, barley and hops.
Brewer Josef Groll creates the first clear, bottom-fermented lager beer, which becomes known worldwide as pilsner.
Louis Pasteur scientifically demonstrates that yeast is responsible for fermentation, leading to better control over the brewing process.
Technological innovations such as steam engines, refrigeration and bottle filling make large-scale, industrial beer production possible.
Small, independent breweries are bringing artisanal diversity back to the world of beer in response to mass production.
The nineteenth century brought drastic changes in the way beer was produced, thanks to the industrial revolution. Inventions such as the steam engine for grinding grain, artificial refrigeration for temperature control during fermentation, and automated bottling plants made it possible to produce and distribute beer on an enormous scale. Large breweries such as Guinness in Ireland and Anheuser-Busch in the United States grew into industrial giants that exported beer around the world. However, this scaling up also caused a homogenization of beer flavors, with local traditions sometimes lost in favor of uniform, mass-produced lager beers.
