According to NBC News:
Attention hot sauce fans: There is likely to be a shortage of Sriracha sauce in the days and weeks ahead. Blame the weather.
Huy Fong Foods, maker of the popular Sriracha Hot Chili Sauce, said a shortage of chili peppers is limiting its ability to produce several of its in-demand sauces, including its Chili Garlic and Sambal Oelek. The California-based company cited climate conditions as part of the problem.
"We are still endeavoring to resolve this issue that has been caused by several spiraling events, including unexpected crop failure from the spring chili harvest," Huy Fong Foods said in a statement to NBC News, adding: "We hope for a fruitful fall season and thank our customers for their patience and continued support during this difficult time."
An April 19 letter from Huy Fong Foods posted on a food distribution website for wholesale buyers said: “Currently, due to weather conditions affecting the quality of chili peppers, we now face a more severe shortage of chili.”
The company sources its chili peppers from Mexico, where a drought is affecting that country and parts of the western United States.
According to the Huy Fong Foods letter, any orders for the affected sauces that were placed after April 19 would not be fulfilled until after Labor Day. The company said it would not accept any new orders before September.
