This beer is made from 5 million year old yeast

You’ve probably heard of aging beer before, but never like this. We’re not quite talking dinosaur beer, but it’s close.

Dr. Raul Cano, a molecular biologist, and retired Cal Poly San Luis Obispo professor is working to bring the world beer featuring yeast that was born 45 million years ago. Yes, really.

Cano started the project after acquiring an Eocene Epoch piece of amber in the early 1990s. With a little help from a local brewery, Cano and his team have managed to extract microscopic bacteria from within the amber, of which they found the crucial yeast strain saccharomyces cerevisiae, better known as “brewers yeast.” According to Cano, once it was established that was the form of yeast his team had found in the ancient amber, it was then just a matter of brewing by trial-and-error.
