- Root beer, in its most classic form, is made by fermenting a mixture of herbs, roots, and bark with water and sugar. The fermentation process occurs when yeast consumes the sugars and converts them into alcohol and carbon dioxide. As a result, the beverage develops a slight alcohol content, usually less than 0.5%.

The fermentation process is a necessary step in the creation of any alcoholic beverage, without which, we would have just plain sugar water. In beer production, yeast fermentation is especially important. Like all alcoholic beverages, the main purpose of yeast for a brewer is to produce ethanol and carbon dioxide from wort carbohydrates. However, t...
The primary types of beer fermentation are: ale/top-fermenting, lager/bottom-fermenting, mixed/”wild” culture fermentation, and spontaneous fermentation. Ale yeast fermentations are often referred to as top-fermenting. Ale yeast strains prefer warmer fermentation temperatures (64F-78F), which promotes more active fermentation with high levels of CO...
The first stage in fermentation is referred to as the Lag Phase. This early part of fermentation is when yeast is acclimating to the physical environment of wort. While fermentation is defined as an anaerobic process, oxygen is critical at this stage to provide ample building blocks for new cells. Here, cells begin uptake of dissolved oxygen, miner...
The time to ferment beer depends on a number of factors including yeast strain genetics, starting gravity, and fermentation temperature. In general, most ales will ferment fully in approximately 7-10 days. Lagers, because of their slower fermentations and need for more conditioning, can take anywhere from 14-21 days.
1. Malting And Milling
Malting refers to the process of germinating and drying barley or other grains. This activates the naturally-occurring enzymes within the grain, making them more readily used down the line in the brewing process. Drying stops enzyme activity, allowing the grains to be stored and transported easily without spoiling. Malting also causes the husk of the grain to become more friable (crumbly), making it easy to pass through a grain mill. Milling the grains crushes the husk of the grain, making th...
2. Mashing
During mashing, the milled malted barley (or other malted grains) is steeped in water at specific temperatures to activate the enzymes, which will break down the complex starches into smaller carbohydrates (sugars). While various mash temperatures can be employed for different purposes, the primary goal of mashing is to create enough simple and fermentable sugars for yeast fermentation. This happens effectively at 145-153F, where amylase enzymes are highly active and can cleave the starches i...
3. Lautering
Once starches are converted into fermentable sugars, the solids need to be separated from the liquid wort. Lautering is essentially like using a very large colander to remove the grains from the liquid, while rinsing the grains with fresh water to extract any remaining sugars.
Fermentation is a critical step in the beer-making process and the world of fermentation can be somewhat complex. From basic yeast metabolism to the array of flavor and aroma compounds, an entire book could be (and has been!) written on best practices. No matter your experience level, novice or expert, having a good grasp of yeast and fermentation ...
Fermentation in root beer is an age-old process used to make the popular beverage. The process involves the conversion of sugar to alcohol and carbon dioxide through the action of yeast and bacteria.
Nov 20, 2023 · In the context of brewing beer, fermentation is the conversion of sugars into alcohol and carbon dioxide by yeast. This magical transformation is what gives beer its unique flavors, aromas, and characteristics.
Root beer is typically made using lactic acid fermentation, in which lactobacillus bacteria are used to ferment a mixture of extracts from various spices, roots, and bark. The lactobacillus consume the sugar in the mixture, producing lactic acid and carbon dioxide as byproducts.

Root beer was originally made with sassafras root and bark which, due to its mucilaginous properties, formed a natural, long lasting foam, a characteristic feature of the beverage. Root beer was originally carbonated by fermentation. As demand and technology changed, carbonated water was used.
