Barq was a pricey cereal that could be found in high-end eateries throughout the galaxy. These grains, resembling pearls, originated from the Outer Rim planet of Qiilura, an area known for its potent, nearly mushroom-like aroma.
In the era of the Clone Wars, the Trade Federation held dominion over Qiilura's barq exports. Furthermore, in the course of Omega Squad's mission to Qiilura, the Trade Federation dramatically increased the cost of barq, citing the incidental harm inflicted on several barq fields and agricultural sites by the clone commandos alongside some of Ghez Hokan's more undisciplined soldiers.
