The Wari variety was chicha: a slowly brewed, beer-like fermented beverage typically made from corn that’s still produced today in South America. The brewery at Cerro Baúl made it for four centuries, surviving any environmental or social problems that may have arisen to become what Williams calls the best-preserved Wari brewery found to date. Brewers would produce 1,500 to 2,000 liters of the stuff at a time and throw multi-day, community-wide drinking festivals to consume it.
The team believes that these breweries were so resilient because they produced their own materials instead of importing them from a central capital. By completing a chemical analysis of pottery fragments found at Cerro Baúl, they found that the clay came from local sources while still retaining common Wari iconography.
Chemical - Analysis - Traces - Biomarkers - Pottery
The chemical analysis was also able to find tiny traces of biomarkers on the pottery associated with chicha de molle, a specific type of chicha made from fermented pepper berries. Excavators also found remnants of discarded pepper berries that had previously been used for brewing. While today’s chicha is usually corn-based, the majority of samples analyzed at Cerro Baúl are the pepper berry variety. Williams says this wasn’t a coincidence: pepper berry trees can survive droughts, making them ideal for the wide range of environments that the Wari empire would’ve encompassed.
Williams says the pepper berry is a common ingredient in most chicha brewing practices, along with the pottery the chicha would be served in, became the Wari brand. The envy of marketing departments everywhere, the beer was cohesive enough to communicate a shared political experience but adaptable enough for communities to sustainably produce it for centuries.
Times - Wari - Kind - Maintain - Interaction
“Even in environmentally bad times, [Wari] could continue to kind of maintain this interaction with their population through this production of beer,” Williams says.
But, of course, researchers couldn’t be sure until...
