Discover 'the world's oldest brewery' in a cave in Israel

Researchers say they have found the world's oldest brewery, with a 13,000-year-old beer residue, in a prehistoric cave near Haifa in Israel.

The plant was discovered when researchers were studying a burial site of semi-nomadic hunter-gatherers.

Beer brewing is said to have been around 5,000 years ago, but the latest discovery will probably overturn the history of beer.

The findings also indicate that beer is not necessarily a byproduct of making bread as previously thought.

The researchers said they could not determine which was first, and in the October issue of the Journal of Archaeological Science: Reports, they hypothesized that beer was cooked for festivals to honor people. deceased.

Li Liu, a professor at Stanford University, who led the research team, told Stanford News: 'This explains the world's oldest record of human alcohol.'

Ms. Liu said they have been searching for clues about the type of plant that the Natufians - those who lived in the middle of the Paleolithic and Neolithic period - ate, and during the search, they found the sign stain of a wine made from wheat and barley.

The analyzed tracks were found in stone mortars - up to 60cm deep - chiselled into the cave floor, used to store, pound and cook different types of plants, including oats, beans and bark fibers , like flax fiber.

Ancient brewing, much more like porridge or porridge, is said to look quite different from the beer we know today.

The research team has successfully recreated the ancient brewing to compare with the beer residue they found.

According to the study, this involves first letting the grain germinate to create malt, then heating the brewed water and letting it ferment with natural yeast.

Ancient wine was fermented but perhaps lighter than modern beer.
