Ancient Chicha Brew In Peru Is "Beer Of Kings"

“The scale of chicha production in this building with multiple fires and vats, indicates that this was not a home-brewing operation,” he added. “It was an elaborate brewery that produced massive amounts of chicha.”

Cerro Baúl is about 250 miles south of Cuzco. In early July, Dr. Williams and colleagues from The Field Museum and the University of Florida discovered more than 20 preparation vats and the remains of what were once open-hearth fire pits. In the fire pits, hot-burning llama and guinea pig dung, along with other refuse from the settlement, were used to boil water and other ingredients to make chicha. These fire pits revealed ash and broken shards of the large ceramic preparation vats, which held 10-15 gallons.

Boiling fruits or grains is the first step in preparing chicha. Like the mash created in the beer brewing process, the boiling vats contained the sugary mass that would be converted to alcohol in the fermentation stage. From these boiling vats, the liquid would be transferred to fermenting jars where it was converted into chicha in about 5-7 days.

In the brewery, researchers also found large deposits of used seeds from the Peruvian pepper tree, Schinus molle. Chicha brewed with these pepper seeds would have produced a spicy beer.

“Today Peruvians make chicha primarily from corn, a tradition passed down from earlier Andean civilizations, including the Inca,” Dr. Williams said. “However, archaeological evidence shows the Wari preferred the spicy chicha made from molle.”

Project botanists are attempting to recreate the ancient Wari beer brewed from the pepper tree berries using traditional pottery. Video of this process can be seen on the Field Museum Expeditions page, a free, interactive online program that follows Field Museum scientists as they conduct scientific research around the world. Through this expedition website, the public can subscribe to free email dispatches from scientists working in the field. Currently, the site features Dr. Williams’ dispatches from the Cerro Baúl excavation site, and a video report on the ancient brewery.

The chicha-making facility is unusual because of its mountaintop location. The closest water source, a major component in making chicha, would have been located down a long, steep mountain trail.

When Wari colonists eventually abandoned the monumental complex atop Cerro Baúl, the ceremonial drinking halls and brewing facilities were treated to elaborate closing rites. After the final batches of chicha were served up to elites in ornate ceramic drinking vessels called keros, the sacred halls were torched. As the fire consumed the building, the beams and thatch roofs would have collapsed followed by the Wari throwing their cups into the fire. As a result of having been buried under collapsed walls, the ruins of the Wari settlement on Cerro Baúl are well preserved.

Archaeologists discovered Cerro Baúl in the early 1980s and conducted preliminary excavations in 1989. Extensive investigations have been underway for the past five years, and this season revealed the first evidence of a large-scale brewery.

“As we continue our excavations, we will learn more about the scale of chicha production and how it fit into the political life of Wari lords on Cerro Baúl,” said Dr. Williams, who specializes in the anthropology of South American empires, and the use of chemical and geophysical science in archaeology.

  1. While walking in the Sacred Valley in Peru, I came upon a group of men who were taking a break from harvesting wheat. I was lost and stopped to ask for directions. They offered me a cup of warm, flat chicha, which was still quite good. The corn harvest had just occurred, so it may have been quite fresh. After downing it, I was immediately offered another. I declined and went on my way.

    Modern Peruvian beer/chicha isn’t spicy, unlike the old stuff.
