Alcohol Technology

From our viewpoint today, it is difficult for us to understand that for many thousands of years, alcohol was an ingrained part of every day life. Unlike today, alcohol wasn’t just one option amongst a suite of substances that offered enjoyment and social interaction. Instead, Alcohol provided us with the ability to survive a newly urbanized lifestyle and develop into the sophisticated, populated civilisations we see today.

As agriculture allowed larger quantities of food to be grown and controlled, villages became towns and towns became cities, growing in complexity.  With large concentrations of people, came polluted water. The alternative to drinking unhealthy water was to drink beer and wines.

There are very few references in the Bible or even ancient Greek writings to water drinking.

“Hippocrates specifically cited water from springs and deep wells as safe, as was rainwater collected in cisterns. The ancients, through what must have been tragic experience, clearly understood that most of their water supply was unfit for human consumption.” 300

It could be said that we owe our status of an advanced civilization to Alcohol. As beer and wine were free of pathogens they allowed the population to flourish.

There are many references to wine being diluted with water in ancient texts. The Greeks viewed drinking diluted wine as a mark of civilized behavior, and believed that only barbarians drank unmixed wine. Although this dilution was obviously a way to moderate the effects of alcohol, it was also a way of sanitizing dirty water as the antiseptic power of alcohol killed many of the bacteria in dirty water.

Alcohol was also known in the East, but it doesn’t play the central role it filled in Europe.

One possible explanation for this is the fact that the East had been purifying its water for centuries, but through the act of boiling it. Tea drinking in China started over 4000 years ago, while coffee drinking started in Ethiopia in the 13th century.

Interestingly, approximately half of all Asian people don’t have any enzyme necessary for complete alcohol metabolism.  We don’t know why this is- maybe because without alcohol in their daily diet, they did not develop the same biological system to handle alcohol as people in the West did.

The alcohol content in ancient wine and beer was low compared with modern alcoholic beverages. However, because wine and beer were such a part of daily life and consumed at every meal, “throughout Western history the normal state of mind may have been one of mild inebriation.” 300

As well as providing a healthy liquid, alcohol also provided nutrition.

The Greek term “akratidzomai” which came to mean “to breakfast,” literally translates as “to drink undiluted wine.”301

Monks relied on beer for sustenance during a fast


Throughout history, many societies and through all classes, getting enough sustenance was a daily challenge. Wine and beer were consumed at every meal because they provided additional calories. 300



Various forms of crude distillation have been mentioned throughout history, although the date and place of its invention are not known.

The Arabic technique of distillation had spread across the Mediterranean in the 8th, 9th and 10th centuries, with widespread use by the Middle Ages. Distillation meant that alcohol became stronger and purer.  Distilled sprits were called aqua vitae the “water of life”. In the context of a world of contaminated and dangerous water supplies, this term was probably more descriptive than poetic. However, some also see the distillation of alcohol as the turning point from a workable co-existence with alcohol to a world where alcohol posed a threat:

“In 1500, Alsatian physician Hieronymus Brunschwig described distillation in the first printed book of the process entitled Liber de arte Distillandi. Because alcohol vaporizes at 172 degrees F (78 degrees C) and water vaporizes at 212 degrees F (100 degrees C) it was now possible to produce much higher percentages of alcohol than would ever be produced naturally….The result was that alcohol moved from being a purifier of water to being a recreational drug.” 302

Because of the need for healthy liquid, alcohol continued to be drunk for centuries. No other alternative to unhealthy water became widely available until the 17th century. At that time, beverages made with boiled water became popular. Coffee, tea, and cocoa thus began to break alcohol’s monopoly on safe beverages.

Even though the Reformation and the 18th century saw a rise in antagonism toward alcohol- mostly at the hands of religious separatists, it had little real effect. In fact, it was only the early advances in water filtration that would allow separatists like the Mennonites to abstain from alcohol.

The fact was that up until the end of the 19th century, the Thames in Britain and many other rivers in other countries were just as polluted as the streams of antiquity.

“Dysentery, cholera and typhoid, all using filthy water as a vehicle, were major killers until the end of the 19th century, rivaling plague in mass destruction. Only the realization that microorganisms caused disease, and the institution of filtered and treated water supplies, finally made water a safe beverage in the West.” 300

The first municipal water treatment plant was built in Scotland in 1804, and in the 1890s, America started building large sand filters to protect public health.

These advancements in water purification came at the same time as alcohol’s dangers were becoming more widely accepted and while religious groups began campaigning for tight controls of alcohol. The all-day drinking of beer and wine by adults and children died out.

Other technical advancements had an impact on how alcohol was consumed. In England, the expansion of the brewery industry  in the late 19th century were results of technical changes in the brewing process that enabled beer to last for longer, and also developments in transport technology that allowed it to be transported more quickly. Breweries became national companies, and therefore they became rich and influential in politics.

In summary, the two technological advances that influenced the use of alcohol to a great degree are the invention of distillation and water filtration.

However, although these two things have effected our drinking patterns have changed in the past century, we still carry the biological legacy. Virtually no person of European origin is unable to break down alcohol, thanks to a set of genes that firstly convert alcohol into acetaldehyde, and then into acetic acid. By contrast, more than 40 per cent of people of Eastern origins lack the gene.
