New yeast strains can produce untapped flavours of lager

Live Mint  

As frequent pub-goers will be well aware, beers come in two varieties—lagers and ales. If a team led by Jennifer Molinet and Francisco Cubillos at the University of Santiago, in Chile, get their way, though, new types of lager may soon arrive, with completely different aromas and flavours from anything currently on tap. But in a paper in PLOS Genetics, Dr Molinet, Dr Cubillos and their colleagues unveiled new hybrids of S. cerevisiae and S. eubayanus. Over the next seven months or so, the team created hundreds of generations of lager yeast, each time selecting the ones with the most desirable traits for making a delicious brew. Commercial lager yeast typically ferments in seven days, half the time the new hybrid needs.
