Canadian Mustard Mills supplies pungent brown mustard seed (Brassica juncea) to food manufacturers across Canada and the United States — the seed behind spicy brown mustards, pickling spice and ethnic foods.
Brown mustard (Brassica juncea) is where the bite lives. Smaller and darker than yellow seed, it delivers the sharp, pungent heat behind deli-style and spicy brown mustards — the kind of heat that clears the sinuses rather than warming the tongue.
That pungency comes from higher volatile oil content, and it is exactly why formulators choose brown mustard when mild won't do. A little goes a long way, which is why it shows up in bold condiments and spice-forward applications.
Spicy brown and deli mustards. Brown seed — whole, cracked or milled — is the backbone of spicy brown, deli-style and Dijon-type mustards.
Pickling spice. Whole brown seed is a core component of pickling spice blends, contributing both flavour and visual character to the mix.
Ethnic foods. Brown mustard seed is essential in South Asian cooking, where it is tempered in hot oil to release its pungency. Food manufacturers serving this segment need consistent, high-quality seed — which is what we supply.
Like all our seed, brown mustard arrives cleaned and sized for food manufacturing: uniform seed that runs clean through grinding and blending lines, lot after lot. We work directly with growers and milling partners across Canada and the US, so quality stays consistent from crop year to crop year.
Seed ships in 25 kg / 50 lb bags with a standard 14-day lead time. Every lot is graded to the Canadian Grain Commission standard with nil extraneous matter — grade and purity details are confirmed against your spec sheet before we ship.
Prefer flour to whole seed? Our toll and custom milling grinds brown mustard to your target particle size and heat level — or talk to us about oriental mustard flour when you want maximum heat.

Brown mustard seed is smaller, darker and significantly more pungent than yellow seed, thanks to higher volatile oil content. Yellow is mild and golden; brown brings sharp, sinus-clearing heat.
