The incursion of the Inka empire, Tawantinsuyu, into the Argentine Northwest combined different strategies to consolidate state power, including the organization of massive feasts with a strong religious component. The Inka required participation from large contingents of conquered communities in these feasts, who were not only involved in the celebrations themselves but also preparation of food and chicha. Large-scale chicha production for these feasts required specific tools, including large bedrock mortars scattered throughout the landscape of the El Shincal archaeological site (Catamarca province, Argentina). To understand this feasting phenomenon and its link with Inka politics in this region, two bedrock mortars and excavated artifacts, including ceramics, lithics, animal bones, and macrobotanical remains are examined. Results indicate that chicha was produced from many different plant resources in large quantities, a phenomenon related to the active role of local communities. Additionally, entheogenic plants were used in some of these chichas.

印加帝国Tawantinsuyu入侵阿根廷西北地区，结合了各种巩固国家政权的策略，包括组织具有宗教信仰的大型盛宴。印加人需要征服社区的大批人参加这些盛宴，他们不仅参加了庆祝活动，还准备了食物和chicha。这些盛宴的大规模chicha生产需要特定的工具，包括散布在整个El Shincal考古遗址（阿根廷卡塔马卡省）景观中的大型基岩迫击炮。为了了解这一盛宴现象及其与该地区印加政治的联系，我们研究了两种基岩迫击炮和出土文物，包括陶瓷，石器，动物骨头和大型植物残骸。结果表明，chicha是从许多不同的植物资源中大量产生的，这种现象与当地社区的积极作用有关。另外，在其中的一些辣椒中使用了有生植物的植物。
