Mostafa Waziri, secretary general of the Supreme Council of Antiquities, said the factory was found in Abydos, an ancient burial ground located in the desert west of the Nile River, more than 450 kilometres south of Cairo.
Each unit includes some 40 pottery basins in two rows, which had been used to heat up a mixture of grains and water to produce beer, Mr Waziri said.
Dr Adams said the factory was apparently built in this area to provide royal rituals with beer, given that archaeologists found evidences showing the use of beer in sacrificial rites of ancient Egyptians.
The necropolis had been used in every period of early Egyptian history, from the prehistoric age to Roman times.
Egypt has announced dozens of ancient discoveries in the past couple of years, in the hope of attracting more tourists.
The tourism industry has been reeling from the political turmoil following the 2011 popular uprising that toppled longtime autocrat Hosni Mubarak.
The sector was also dealt a further blow last year by the coronavirus pandemic.
