Burning down the brewery
Elite women brewed a beer-like drink at ancient Wari site – the first diplomatic outpost between Andean empires
CHICAGO--An extensive Wari imperial outpost on the top of a sacred
mountain in what is now southern Peru was ceremoniously evacuated and
partially burned to the ground 1,000 years ago, Field Museum
archaeologists and their colleagues from the University of Florida and
the Contisuyo Museum in Peru report in the next issue of the
Proceedings of the National Academy of Sciences.
The last building to be torched as the Cerro Baúl colony was abandoned
was a sophisticated brewery with a 1,800-liter capacity – no
micro-brewery, even for its time.
The elaborate abandonment of the colony began with the brewing of a
final batch of chicha, a fermented alcoholic drink that played a
central role in the Wari culture. A week later, the residents drank the
chicha in an extensive feast and ceremony. As a sacrifice to the gods,
the colony's religious and political leaders threw 28 precious ceramic
vessels into the conflagration – presumably after quaffing the brew.
"Chicha, which is often made from maize, was at the heart of this
culture, and this is one of the oldest and largest pre-Inca breweries
ever discovered in the Americas," said Patrick Ryan Williams, Curator
of Anthropology at The Field Museum and co-author of the research
report. "Our analyses indicate that this specialty brew was a
high-class affair. Corn and Peruvian pepper-tree berries were used to
make the beer, which was drunk from elaborate beakers up to half a
gallon in volume."
Chicha was so important to the Wari that it was brewed by a group of
select, high-status women. Archaeologists were able to conclude this
from the large number of shawl pins found in the three-room brewery –
but conspicuously absent from other areas of the expansive ruins.
These elite brewmistresses were probably selected for their beauty or
nobility. The Inca, who followed in the Wari's footsteps, continued
this practice centuries later: Their chicha was also brewed by an elite
class of women who were cloistered in "houses of chosen women."
"In Inca society, wealth and power depended on the knowledge and skill
of elite women," said Donna Nash, Adjunct Curator at The Field Museum,
Adjunct Professor at the University of Illinois at Chicago and
co-author of the report.
Inca gatherings large and small, sacred and politically crucial,
depended on the exchange of valued gifts and the hospitality of the
emperor, especially on offering copious amounts of chicha, she
explained. The chosen women and other Incan royalty produced fine
shirts elaborated with heraldic symbols of state office and social
rank, the most prestigious of all gifts. They also brewed the beer.
"Without cloth and beer, these ancient empires could not have
functioned," Nash said. Therefore, women were crucial to the ancient
empires of the south-central Andes."
The researchers report on their findings in "Burning down the brewery:
Establishing and evacuating an ancient imperial colony at Cerro Baúl,
Peru," an embargoed research report to be published on-line Nov. 14 in
the Proceedings of the National Academy of Sciences. It will be the
cover story in the subsequent print version of PNAS
The lead author is Michael Moseley, Distinguished Professor at the
University of Florida, Gainesville, as well as Research Associate and
former Curator at The Field Museum.
"There are lots of other imperial Wari sites, but they are all plunked
down in the wide open flat land. This is the only one that's high on a
mountain," Moseley said.
Remote, formidable site
Cerro Baúl is a mesa more than 8,000 feet above sea level that is
dominated by an intimidating summit rising 2,000 feet above the mesa.
In 600 A.D., the Wari chose this natural bastion as a base for an
imperial settlement, but it was not been occupied before or since
because it is so difficult to carry water and supplies up the
treacherously steep inclines of the summit.
In fact, the Wari settled here precisely because it is such a
formidable, impractical location. The tough living conditions there
made a colony easy to defend and sure to impress the neighbors,
according to the authors.
Those neighbors were the rival Tiwanaku, who reigned to the south in
what is now Bolivia. These two major contemporaneous empires usually
kept their distance. Elsewhere, they were separated by a buffer zone of
at least 60 miles.
At Cerro Baúl, however, the Wari apparently decided to establish a
foothold deep inside the territory controlled by the Tiwanaku to serve
as a point of contact for political relations. That makes this the
oldest known diplomatic outpost between any Andean states. It survived
four centuries. "These were frontier outposts, facing off, but with
very little contact," Moseley said. "The Wari and the Tiwanaku are not
borrowing anything from each other, even though we find artifacts
brought in from other cultures thousands of miles away."
The politics of international relations in South America began at Cerro
Baúl 1,500 years ago, Williams said. "There is a lot we can learn from
this site about how expansive states interact with each other and about
the nature of human diplomacy," said Williams, who specializes in the
anthropology of South America and the use of chemical and geophysical
science in archaeology.
Class-conscious culture
Cerro Baúl, with a population of less than 1,000, was the Wari's
southern most colony. It also extended over two neighboring hills,
Cerro Mejia and Cerro Petroglifo, and relied on an impressive system of
irrigation canals to bring water from the neighboring Torata River. The
colony, which survived 400 years, was inhabited by three classes of
people: commoners, mostly farmers and herders; supporting artisans,
technicians and religious specialists; and a hierarchical class of
governing nobles.
The quality and quantity of material possessions, housing, food, dining
ware and other items – including chicha – varied by the class and rank
of the people. By studying what was found where among the site's
extensive ruins, archaeologists have been able to reconstruct what life
must have been like for these people more than 1,000 years ago.
For example, only nobles and leaders drank chicha from pottery vessels
decorated with an image of the culture's paramount deity, the
"Front-Facing God." Although these vessels were smashed on "moving
day," some of them have been reconstructed from the broken pieces. In
addition to the brewery, an opulent palace was burned to the ground –
but only after an opulent banquet of deer, llama or alpaca, and seven
types of ocean fish. Condor, pygmy owls and flycatchers were probably
sacrificed at the banquet. Smashed serving and dining ware litter this
site, too. Temples around the base of Cerro Baúl suggest that the Wari
viewed the mountaintop as a sacred place.

Shawl pin
The large number of shawl pins found in the brewery but conspicuously
absent elsewhere at the excavation site indicates that the elite women
who, would have worn such pins, brewed the chicha, an alcoholic
beer-like beverage that was central to the Wari culture.
