Scientists find original 'lager' yeast in Argentina.
There are two types of yeast used in brewing beer:
1) Saccharomyces cerevisiae - Ales; top fermenting, prefers 65-70 F
2) Saccharomyces pastorianus - Lagers; bottom fermenting, prefers 40-45 F
Lagers were invented much later, probably in the 1400s, and it is thought that Saccharomyces pastorianus is a hybrid between Saccharomyces cerevisiae and another yeast. Scientists have recently found yeast in Argentina that could be the mother of all lager yeast.
