On exhibition in this gallery are ethnographic as well as a number of botanical objects that are associated with the production, trade and consumption of basi, the Iloko traditional wine made of sugarcane juice and native growing herbal fermenting agents.

Adjacent to the “The Basi Revolt” Gallery, this exhibition is titled “Containing the Cultural World of Basi: Defining Ilocos and the Ilocano” and has  a sub-section, “Reconstructing Ilocano Identity: Basi Trade and its Social Networks”. The exhibition themes reflect the cultural significance of basi especially among the Ilocano and neighboring ethnic groups in the Cordillera with whom they have most closely maintained social and economic relations through the centuries. Locally produced and foreign ceramics, cloth, ornaments that include trade beads and local filigree, and basketry, are among the items on exhibition.
