Huy Fong Foods' sriracha hot sauce, in the green-capped bottle with the rooster label, has been hard to find for the past few years. Strained supplier relations coupled with adverse agricultural conditions have left Huy Fong Foods' sriracha out of stock at many grocers nationwide. Underwood Ranches, a farm owned by Craig Underwood based in Ventura County, California, supplied Huy Fong Foods' peppers for 28 years. Huy Fong Foods claimed it overpaid Underwood Ranches for its crops from the 2016 season. Huy Fong Foods declined CNBC's request for an interview.
