Israelis brew beer from ancient yeast

Israeli scientists isolated yeast from ancient pottery used to brew beer and used it to create the same libation that presumably the Egyptian pharaoh, Iron Age rulers, and ancient Jewish leaders all drank.

The discovery of the yeast and re-creation of the ancient beer was announced last week by researchers from the Hebrew University of Jerusalem, the Israel Antiquities Authority, Tel Aviv University, and Bar-Ilan University.

The jars from which the yeast was recovered date back to the reign of the Pharaoh Narmer, circa 3000 BCE, to the Aramean King Hazael, around 800 BCE, and the Prophet Nehemiah, about 400 BCE.

The researchers cleaned and sequenced the full genome of each yeast specimen and discovered that they were similar to those used in traditional African brews — and to modern beer yeast.

An Israeli beer expert, Itai Gutman, helped the scientists make the beer. The brew was sampled by certified tasters from the International Beer Judge Certification Program.

The testers determined the brew was high quality and safe for consumption. One brew was said to be similar in color, aroma, and flavor to one made from a well-known English ale yeast.

“This ancient yeast allowed us to create beer that lets us know what ancient Philistine and Egyptian beer tasted like,” Ronen Hazan, a microbiologist from  Hebrew University and one of the lead researchers in the project, said. “By the way, the beer isn’t bad. Aside from the gimmick of drinking beer from the time of King Pharaoh, this research is extremely important to the field of experimental archaeology — a field that seeks to reconstruct the past. Our research offers new tools to examine ancient methods, and enables us to taste the flavors of the past.”
