Almost a decade ago, Leonard Guarente at Massachusetts Institute of Technology found a gene called SIR2 in brewer's yeast that, when mutated, seemed to extend the yeast's life.
Any normal brewer's yeast can be used in his process but the lifespan of the yeast is much longer than in traditional processing, where yeast degenerates after three brews and starts to affect the quality of the beer, says Heiliger.
