Tired of that old beer taste? Researchers might have a new brew for you.

Using yeast strains found in the bark of trees in Patagonia, the researchers brewed up new hybrid yeasts that could one day lead to beers with strikingly different tastes and aromas.

"All the lager beers that we drink now come from a single event from a yeast generated 500 years ago," said Francisco Cubillos, principal investigator of the study.

The birth of lager yeast, formally known as Saccharomyces pastorianus, was a happy accident that occurred about the year 1600.
