During the Supply and Demand quest after speaking to Aefre, Maea does not give the option to go speak to Bricanta about the prices of Bitter Squash. I tested both high and low reputations with Hose Doemenel and the option just doesn't appear. The attached save is after speaking to Aefre and doing a favor for Bricanta.
Edit: Great, the save didn't actually attach. Have a screenshot instead.
