Did you know that Is beer one of the oldest drinks made by humans? And who doesn't like a good beer on a day of intense heat? Is there anything more refreshing than feeling its icy foam and notice the slight dizziness of happiness?

Yes, we like beer, and as we like it so much we realized that some of the most significant human inventions could Owing to it, in large or in part.Share us to see what it is about.

Agriculture

Agriculture is a milestone in human history, which allowed us to move from nomadic peoples to established villages.The food no longer had to be chased (hunted, caught) but only sown and harvested.

5 significant advances of humanity and beer?

We tell you at the beginning that beer is the oldest drink.Imagine that the ancient Sumerian nomads, between 9000 and 7000 BC, they began their barley plantations in the Mesopotamia region.

It was always believed that the planting of this grain was for the production of bread , but recent studies have thrown lights that give a totally different twist to the use of barley: residues of this were found in old vessels, indicating that they drank some drink made with barley...

Writing

Another of the most important technologies that human beings have invented and mastered.Before and after writing means pre-history and History .Well, beer is also involved in this, since the Sumerians who planted and harvested it, carved pictograms on clay .Alli recorded and recorded commercial transactions, but also recipes of beer!

Stephen Tinney , a specialist in ancient texts at the University of Pennsylvania, discovered that more than 160 cuneiform writing symbols were associated with beer .

Cuneiform writing

And they needed to record the production of the drink, including wheat beer, so there are many tablets alluding to the delicious liquid.

Obviously we cannot categorically state that beer would have a total influence on the invention of writing, but if it is amazing to see that in remote times it was necessary to record at least how it was made.And they used the new invention, writing , to do so.

Pasteurization

Did you know that it was beer (and not milk) that allowed Louis Pasteur to lay the foundations of the modern microbiology and the discovery that heating the liquid at a certain temperature killed bacteria?

Luis Pasteur

In 1876 Louis Pasteur wrote Etudes sur la biere ( Studies on beer ), where I put his research, how he had worked as a consultant in some Breweries, he wanted to know why the beer became bitter.He analyzed the yeast cells and noticed the presence of microorganisms that until then were not known, the bacteria .

I showed that they were responsible for the bad smell of beer and that, through the method called, obviously, pasteurization , the bacteria died.The temperature should be between 65 and 70º Celsius, for a certain time, for liquids to be considered pasteurized.

Refrigeration

Because you didn't know that beer was only manufactured and sold in the cold months .Inclusive, for the maturation process, tons of natural ice were required to be transported to underground cellars because there was little thermal variation in these, since specific temperatures were needed.

One of the first refrigerators

All this turned the drink very expensive.At that time, the Irish brewer Guinness contracted the engineer Carl von Linde to develop an artificial cooling system , which in the first instance It was extremely positive to cool the beer while it was being produced.

It was economized in the transport of the ice blocks, and it was then possible to sell the beer always cold, even if it was hot.

The refrigeration system not only served to make beer all year round, but also meant a breakthrough in terms of maintenance and preservation of food worldwide.

Ph scale

Nowadays it is very common to see on the labels of any product “keep the natural Ph”, or “with natural Ph”.The Ph is the potential of hydrogen ions , or in other words, the amount of hydrogen ions present in the proteins.

At the beginning of the 20th century, the German brewer Carlsberg had a big problem to define how acid the beer they produced was, and used a scientific terminology: "very acidic", "good" or "basic" to indicate acidity levels.

To end this, the Chemical Danish Soren Sorensen developed the hydrogenation potential scale or Ph.While working in the brewery's laboratory, Sorensen investigated the effect of ion concentration on proteins, and saw that the more acid it is A drink has a greater amount of hydrogen ions.

Soren Sorensen

This model, after few revisions, was used worldwide, and is now essential for to any chemical procedure.

As you have seen, beer has often played a leading role in several of the most important inventions of the human species.
