Imagine an empire stretching across deserts, mountains, and jungles for thousands of kilometers, but one that had no concept of coinage. In it, power was measured by your ability to feed, clothe, and give drink to those you summoned to work.
Tawantinsuyu — that was what the Incas themselves called their world, "the four united quarters" — looked from a bird's-eye view like a nervous system stretched over the spine of the Andes. Its spinal cord was the Qhapaq Ñan road network, stretching, according to UNESCO estimates, more than 30,000 km, with rope bridges made of ichu grass and tambo stations at every day's march. Along these arteries, like the fat cells of an organism, stood qullqas — round stone storehouses where maize, quinoa, freeze-dried chuño potatoes, and textiles were kept. All of this was tracked without ink, using knotted quipu — cords of cotton and wool, where color, knot type, and position encoded numbers and categories. And the main fuel of this system — human labor in the form of the mit'a obligation, when communities sent their people to build terraces, serve, or fight.
The paradox is that for all this logistical might, there was no labor market in the Andes as we understand it. The state didn't pay wages, because money in the modern sense didn't exist, and value was measured by access to resources and labor. Instead, the principle of redistribution and reciprocity worked: you give the state your time and muscle, the state takes on the obligation to sustain you. Mobilized workers were housed in barracks, issued ponchos and sandals, fed from those very qullqas — and given drink. Spanish chroniclers later described with astonishment how thousands of people gathered for work without a single peso in their pockets, but with complete confidence that they would be fed.
Corn beer, called akha in Quechua and kusa in Aymara, was not a beverage in this system but a social protocol. It was brewed from special varieties of maize, often from sprouted grain where the starch had already begun converting to sugars, and then fermented to a light strength — enough to loosen tongues but not knock you off your feet. Chroniclers and ethnographers agree: akha was not currency, you couldn't pay with it at a market, because there was no market on an imperial scale. It functioned as a sign, as a seal on a contract, as an invitation you couldn't refuse. When an Inca or his viceroy wanted to seal an alliance with the chief of a distant valley, he didn't sign a paper — he offered a ceramic kero brimming with foaming chicha.
To refuse meant to sever relations; to accept meant to acknowledge hierarchy and mutual obligations. So chicha was poured strictly according to status: some received it in a gold vessel, others in wood; some were served first, others last — and this choreography of drinking was read by everyone present without translation. State hospitality was a mandatory ritual, part of the labor contract: you came to work your mit'a, and the state was obliged to throw a feast, feed you llama meat, and get you drunk to the point of collective euphoria. In a sense, chicha was the liquid equivalent of cloth — just as valuable, just as portable, but fundamentally non-accumulable: a resource that had to be drunk here and now, together. Archaeologists find enormous jars smashed in communal feasts on the plazas — not a single container left that could have been traded later.
Who brewed this liquid that held the empire together? The answer leads to the houses of the aclla — girls selected by the state in childhood from communities across the country. They were taken to special complexes called acllawasi, where they lived under the supervision of elder women called mamakuna, learning to spin the finest vicuña wool, weave ceremonial tunics, and prepare ritual food. Preparing akha was one of their duties, and a labor-intensive one: the grain had to be sprouted, dried, ground on stone querns, boiled, and fermented in enormous clay vessels. This work demanded time and ritual purity, because the drink was meant for both people and gods, for libations to the earth and the mountains.
The sources don't allow us to reduce the aclla to a faceless army of thousands of brewers, as popular accounts sometimes do. They are spoken of primarily as producers of cloth — the most valued imperial product — and as priestesses of the cult, with brewing being part of a broader complex of state hospitality. In essence, their labor was as infrastructural as that of the masons building storehouses: their product was the very possibility of bringing people together. Their status was dual — at once honored and isolated, for they were removed from ordinary family ties and incorporated into the body of the state. The Spaniards found the acllawasi still functioning; by their estimates, there were thousands of girls there, and history has preserved no more precise count.
If you want to see how chicha worked at the scale of the state, you should go to Huanuco Pampa — one of the largest Inca administrative centers, built at an elevation of 3625 m above sea level on the central plateau. The city was planned as a machine for receiving people: a vast central plaza capable of holding thousands of the assembled, palaces for the elite, barracks for workers, and rows of qullqas lined up on the hillside. Archaeologists have mapped hundreds of storage structures there and the traces of kitchen zones with hearths, grinding stones, and fragments of giant fermentation vessels. Charred grain and dozens of wide-mouthed tinaja jars add up to an assemblage that archaeologists confidently link to brewing: food and drink were prepared here for the days of state gatherings, in quantities far exceeding the needs of the permanent population. The city essentially stood empty most of the year and came alive, like a fairground, when people were summoned for labor or ceremonies.
The logic is simple and brutal in its efficiency: to make people travel hundreds of kilometers to build a road or serve, a command isn't enough — people must be fed, given drink, and impressed. At Huanuco Pampa, this impression was created by an architecture of generosity — when community chiefs drank from identical vessels alongside representatives of Cuzco, they physically experienced their incorporation into the empire. Smashed pottery, animal bones, and hearth traces speak of recurring feasts, where chicha flowed like glue, binding different ethnic groups into a single political organism. It was parliament, dining hall, and temple all at once — and every swallow in it ratified the contract. Exactly how many days such a gathering lasted at Huanuco Pampa, archaeologists still debate.
It might seem that this link between beer and power was an Inca invention, but archaeology reveals a deeper root. In southern Peru, in the Moquegua Valley, atop the mesa of Cerro Baúl, stood an administrative center of the Wari Empire of the Middle Horizon period, dated 600–1000 CE. This was a state that preceded the Incas by several centuries, with its own network of roads and colonies, and it too built palaces where beer flowed like a river. Only there the raw material was the berries of the Peruvian pepper tree, Schinus molle — the pink clusters of the molle tree, which still grows on the slopes of the Andes today. Botanical remains and the architecture of the elite complexes at Cerro Baúl make it unambiguous: the fermented drink was made specifically from molle, and its production was large-scale and centralized.
The process was labor-intensive and calculated: berries were gathered by hand, then cleaned by winnowing — tossed in the wind to separate out debris — and boiled to produce a sweet wort for fermentation. By archaeobotanists' calculations, producing 20 liters of the drink required about 4000 berries, turning the harvest into a logistical operation comparable to procuring grain. In different rooms, the density of molle seeds varied sharply, and researchers identified four modalities: from concentrations of >1000 seeds in palace production zones to <100 as isolated finds in ordinary houses. This distribution is like the state's fingerprint: where density goes off the charts, the state's pot was at work. The Wari vanished long before the Incas arrived, but their skill at turning berries into politics outlived their palaces.
And here the butterfly effect of Andean history reveals itself: the tradition of brewing power from a fermented drink turned out to be older than Tawantinsuyu itself. The Incas didn't invent this mechanism; they inherited it, replacing molle berries with maize akha and embedding it into an even more massive system of storehouses, roads, and quipu. So chicha was not a magic alcoholic crutch without which the empire would have collapsed overnight, like a house of cards without glue. In a state where power was built on redistribution and personal reciprocity, it was a material language — the way generosity became subordination, and collective intoxication became an oath of loyalty. The empire spoke not in decrees but in poured jugs, and as long as this language was understood in every valley, the roads remained passable and the storehouses full — even though no one ever figured out exactly how many jugs it took to hold the Andes together.
