It is a stated fact that beer is as old as the society it self as it has been mentioned in ancient texts, that are more then 5,000 years old. So this wonderful liquid has been around for quite a while. However one thing that is more surprising then the creation of beer is that scientists in the 1950s debated over the idea that beer, not bread was the start of the development of agriculture. Beer has become a commodity is consumed and appreciated throughout the world and each country has its own beer varieties.
According to history brewing beer was done at homes as a part of meal preparations and as society became more and more advanced so did the production of beer which eventually became a business in most of the countries. Throughout the world the production of beer grew with the passage of time from previously being produced in pots and jars to the current microbrewery equipment used for large scale production. It hasn’t been easy to obtain proper evidence regarding the production of beer in the ancient times as old microbreweries only used basic microbrewery equipment, such as a fire, some jars and cooking vessels. These materials are not exactly unique to the brewing process as such, as jars and pots that were used on a daily basis could be used for the production of beer.
One of the oldest microbreweries was found in southern Egypt and it dates back to over 5,000 years ago. Archeologists, at this site, found lot of material that indicated that brewing was done there. In the middle of Egypt along the Nile another ancient brewery was discovered. Some of the rooms were used for cereal processing this indicated that those rooms were used either used as a brewery or a bakery. It was discovered recently that the Romans also knew how to brew beer and had their own breweries. However most of these are just facts. To determine whether a particular site is used for brewing one would need to search chemical evidence; however that is next to impossible.
So in short brewing beer is not exactly that easy; the things excavated at those places could easily be used to produce bread. Hence the residues obtained could have come from baking. There will always be some sort of evidence that will prove the existence of ancient beer however it will always lack physical evidence. So until and unless proper evidence has been found out, no one can say for certain whether those were bakeries or breweries. For further detail refer to the website: http://www.brewbasement.com
