Spelt was introduced to the United States in the 1890s. In the 20th century, spelt was replaced by bread wheat in almost all areas where it was still grown. The organic farming movement revived its popularity somewhat toward the end of the century, as spelt requires less fertilizer. Since the beginning of the 21st century, spelt has become a common wheat substitute for making artisanal loaves of bread, kinds of pasta, and flakes. By 2014, the grain was popular in the UK with the crop being grown there as well as in Kazakhstan and Ukraine, with shortages reported.
