What country grows most of the mustard seed used to make France’s famous Dijon mustard?
As of 2019, most of the mustard seed produced in the world—including for France’s most famous moutarde—“Dijon”—is grown in either Canada (specifically in the province of Saskatchewan), Nepal, or Russia. There are companies in Burgundy (near the city of Dijon) that process seeds to make mustard, but the seeds themselves are almost assuredly grown in Canada. (Importing from Nepal has a number of logistical challenges, and today, importing from Russia has political ones.) According to the US-based Agricultural Marketing Policy Center, Canada, Nepal, and Russia combined have historically produced about 70 percent of the world’s mustard seeds.
