For lovers of this iconic hot sauce, the data is not good. There is a critical shortage of Sriracha and similar products due to drought in the area where the condiment gets its kick. Red jalapeños are the key ingredient in Sriracha, and climate change is punishing them.
Jalapeños grow mostly in northern Mexico and portions of the Southwest U.S. In Mexico, most of the crop is grown in the far northern states, just south of the U.S. Mexico border. The largest producing states in the U.S. are California, New Mexico, and Texas.
The main growing season for red jalapeños is during the first four months of the year. Figure 1 shows the percent of normal precipitation during this period (January thru April) in northern Mexico and the Southwest U.S. Rainfall totals during the growing season were below normal across most of this zone.
