The joint Egyptian-American archaeological mission, headed by Dr. Matthew Adams of New York University, and Dr. Deborah Fishak of Princeton University, working in North Abydos, Sohag, has uncovered what is believed to be the oldest high-production brewery in the world.
Dr. Mostafa Waziry, Secretary-General of the Supreme Council of Antiquities, said that this North Abydos factory is likely to date back to the era of King Narmer and that it consists of eight large sections with an area of 20 m length x 2.5 m width x 0.4 m depth, which were used as units for beer production, as each sector contained about 40 earthenware ponds arranged in two rows to heat the of clay placed vertically in the form of rings.
Dr. Matthew Adams, Head of the mission, indicated that studies have proven that the factory was producing about 22,400 liters of beer at a time, and it may have been built in this place specifically to supply the royal rituals that were taking place inside the funeral facilities of the kings of Egypt. Evidence for the use of beer in sacrificial rites was found during excavations in these facilities.
It is worth noting that a number of British archaeologists discovered this plant at the beginning of the 20th century, its location was not precisely determined, and the current expedition was able to re-locate and uncover it and its content.
