Uncovering The Yeast Mystery: Does Every Beer Contain Yeast?

Yes, all beer has yeast. Non-alcoholic beer will also contain yeast, even though it is very hard to stop the yeast from doing what it does best. You do not have to add commercially produced yeast to your wort to make beer, as wild, local yeasts can be trusted to produce beer. Beer is one of the earliest alcoholic beverages known to humans and is essentially fermented grain water.

Archaeological evidence suggests that beer and bread were both discovered around the same time

Beer is one of the oldest human-produced drinks. The written history of ancient Egypt and Mesopotamia records the use of beer, and the drink has spread throughout the world. A 3,900-year-old Sumerian poem honouring Ninkasi, the patron goddess of brewing, contains the oldest surviving beer-recipe, describing the production of beer from barley bread, and in China, residue on pottery dating from around 5,000 years ago shows that beer was brewed using barley and other grains. Some say the invention of bread and beer led to the development of technology and static civilization.

Beer may have been known in Neolithic Europe as far back as 5,000 years ago, and was mainly brewed on a domestic scale. The process by which the production of beer was discovered is a matter of debate. Author Thomas Sinclair says in his book, "Beer, Bread, and the Seeds of Change: Agriculture's Imprint on World History" that the discovery of beer may have been an accidental find. The precursor to beer was soaking grains in water and making a porridge or gruel, as grain was chewy and hard to digest alone. A thick gruel could be baked in the sun or on a hot stone to make flatbread; a thin gruel could be left to ferment into beer. The Mesopotamian use of bread in brewing has led to much debate among archaeologists, some of whom have suggested that bread must therefore be an offshoot of beer making, while others have argued that bread came first and was subsequently used as an ingredient in beer.

It is useful to think of both beer and bread as food preservation strategies that allow for collected cereals to last longer before spoilage than they may otherwise. As to which came first, it is often a problem of preservation and luck resulting in being able to find data that suggests the presence of these food products. It's also important to note that all alcohol contains yeast. Although some alcohols contain more yeast than others--beer, for example, has a high yeast content compared to vodka--every alcoholic beverage will require yeast to process sugar into ethanol. The question, stated in another way, then, could be asked, “do you have to add yeast to make beer?” And the answer to that question is no. You do not have to add commercially produced yeast to your wort to make beer. Indeed, for thousands of years, our ancestors trusted in the wild, local yeasts to “work their magic,” and produce beer for them. You can make beer without yeast, but you really cannot call it beer. It would be, as stated above, grain water, or grain tea.

Non-alcoholic beer contains trace amounts of alcohol due to yeast fermentation

Non-alcoholic beer is initially brewed with the same ingredients as alcoholic beer, which includes water, grain, hops, and yeast. The grain provides the sugars for the yeast to ferment, which creates alcohol as a by-product. However, brewers use different tactics to make sure the packaged end-product is alcohol-free (or close enough). Non-alcoholic beers do contain varying levels of sugar, as fermentation is responsible for breaking sugar down into alcohol.

Non-alcoholic beer contains yeast, and it's very hard to stop the yeast from doing what it does best, even beers that are labeled as non-alcoholic will contain trace amounts of alcohol. Non-alcoholic beer isn’t the only drink out there that can be considered “non-alcoholic” by the TTB but still contain trace amounts of alcohol.

Wild yeasts have been used to produce beer for thousands of years

During the Agricultural Revolution, we began growing crops, domesticating livestock, and building cities. This period in human history is referred to as the first Agricultural Revolution. The second took place thousands of years later, only a few hundred years ago when we started using industrialized machinery to farm. Ten thousand years ago, long before any of us knew what we were doing with food beyond hunting and gathering and moving around, we decided to settle down and stop chasing our food. It's also important to note that all alcohol contains yeast. Although some alcohols contain more yeast than others--beer, for example, has a high yeast content compared to vodka--every alcoholic beverage will require yeast to process sugar into ethanol.

So, to replicate the taste of a true beer, even non-alcoholic versions will include yeast. In fact, it is important to note that, because non-alcoholic beer contains yeast--and it's very hard to stop the yeast from doing what it does best--even beers that are labeled as non-alcoholic will contain trace amounts of alcohol. The question, stated in another way, then, could be asked, “do you have to add yeast to make beer?” And the answer to that question is no. You do not have to add commercially produced yeast to your wort to make beer. Indeed, for thousands of years, our ancestors trusted in the wild, local yeasts to “work their magic,” and produce beer for them. If you are interested in a sort of reclamation of ancient brewing practices, this approach would certainly be one to take. Of course, you can make beer without yeast, but you really cannot call it beer. It would be, as stated above, grain water, or grain tea.

Non-yeast beer is grain water or grain tea and not beer

No, you do not have to add commercially produced yeast to your wort to make beer.

Archaeological evidence suggests that beer and bread were both discovered around the same time and that both contributed to humanity's evolution from being primarily hunter-gatherers to settling down and forming communities. As grains are very filling, agriculture developed around farming grains that could be used to make bread, and beer was then probably discovered by some of these grains turning bad and fermenting.

People often forget that one of the strongest, underlying flavors in all beer is yeast. So, to replicate the taste of a true beer, even non-alcoholic versions will include yeast. In fact, it is important to note that, because non-alcoholic beer contains yeast--and it's very hard to stop the yeast from doing what it does best--even beers that are labeled as non-alcoholic will contain trace amounts of alcohol.
