In which style of beer would you typically find Saccharomyces pastorianus?

• A. Ales
• B. Wheat beers
• C. Lagers
• D. IPAs

Answer: (C)

Saccharomyces pastorianus is a yeast strain predominantly used in the production of lagers. This yeast is known for its lower fermentation temperature compared to its ale counterpart, Saccharomyces cerevisiae, which ferments more effectively at warmer temperatures. The cooler fermentation profile of S. pastorianus results in the clean, crisp flavors that are characteristic of lager-style beers. This yeast has a unique ability to produce fewer esters and phenolic compounds, allowing the malt and hop profiles to shine more clearly in the final product. In the context of brewing, lagers are fermented at temperatures typically ranging from about 45 to 55 degrees Fahrenheit (7 to 13 degrees Celsius), which aligns perfectly with the fermentation preferences of S. pastorianus. As a result, this yeast is fundamental for achieving the signature qualities of lager beers, making it the ideal yeast choice for this style.
