Stout, Serpents & Saccharomyces cerevisiae

Stout, Snakes & Saccharomyces cerevisiae

The yeasts used to brew Ireland’s classic stout are genetically distinct from the ones used to make other beer styles. The Guinness brewery for example, has kept a record of the yeast strains it has used going back to 1903. A genetic analysis shows these are distinct from those used to brew other dark beers.
