The yeast used to bake bread and brew root beer is scientifically known as saccharomyces cerevisiae. It is a species of yeast which has been used since the ancient times for the purposes of baking and brewing. It is known as a top-fermenting yeast.
It is used in the brewing of beer along with other varieties of yeasts such as Saccharomyces carlsbergensis and Brettanomyces. It is called so because during the process of fermentation process the yeast rises to the top of the vessel which is used for the process of fermentation.
Yeast also helps the bread to rise while it is being baked. The varieties of beer which use top-fermenting varieties of yeast are called ales. It is for that reason that these yeasts are also sometimes called ale yeasts. Top-fermenting varieties of yeast are unable to ferment some types of sugar. Hence the resulting beer has a sweeter and fruitier taste.
