Arizona Is a hub for matzah wheat.

Hasidic Jews from Brooklyn have been increasingly sourcing wheat for their Passover matzah from farmers in Arizona. Excessive moisture in wheat kernels can result in fermentation, rendering the harvest unsuitable for Passover use. But rain is scarce in Arizona, which allows for a stricter standard of matzah production. Rabbis from New York travel to Arizona in the days leading up to the harvest, where they inspect the grains meticulously to ensure they are cut at the precise moisture levels.
