Canadian Mustard Mills supplies #1 grade yellow mustard seed (Sinapis alba) to food manufacturers across Canada and the United States — cleaned, sized and consistent, from sample quantities to full truckloads.
Yellow mustard (Sinapis alba) is the variety behind classic prepared mustard: golden colour, approachable flavour, and a gentle warmth rather than a sharp bite. For most North American condiment makers, it is the default — the seed everything else is blended against.
Because yellow mustard is mild, it carries other flavours well instead of overpowering them. That makes it the right starting point for prepared yellow mustard, mayonnaise-style dressings, and any formulation where mustard should support the recipe rather than dominate it.
We supply #1 grade yellow mustard seed, cleaned and sized for food manufacturing. Our seed comes from prairie growers in Canada — the country's mustard belt — with a US supply path available for American buyers who need domestic origin or shorter cross-border lead times.
Every lot is cleaned to remove foreign material and sized for uniformity, so it runs clean through your grinding, milling or pickling line. We ship #1 grade seed with nil extraneous matter and moisture at 9.5% max — grade, purity and screen-size details are confirmed against your spec sheet before we ship.
Prepared mustard. The classic application — ground in-house or bought as flour, yellow seed is the base of prepared yellow mustard across North America.
Milling into flour. Many of our customers mill yellow seed themselves; others buy our yellow mustard flour milled to their target mesh. We supply both, so you can choose whichever fits your line.
Pickling and brining. Whole yellow seed goes directly into pickling spice blends and brines, where its mild flavour and golden colour are exactly what the application calls for.
Food-grade seed has to run clean. Our yellow mustard seed is cleaned to remove dockage and foreign material, then sized for uniformity — so your grinders see consistent feed and your QA sees consistent results.

Canadian Mustard Mills works directly with mustard growers and milling partners across Canada and the United States. We don’t compete on being the cheapest bid — we earn your business by being the most dependable one: specification-driven sourcing, consistent quality from batch to batch, and delivery you can plan around.
Because we sit close to both the farm and the mill — with partner production across 3 facilities in Canada and 2 in the US — we can match a formulation to the right seed lot, the right grind, and the right heat level, then hold that spec over time. That’s what a supply partner is for: fewer surprises in your QA lab, and one accountable contact from sample to truckload.
Prepared yellow mustard is the classic use, but food manufacturers also mill it into yellow mustard flour, use it whole in pickling spice blends and brines, and grind it in-house for custom formulations.
It is the top grade for mustard seed — uniform size, high purity and minimal foreign material, graded to the Canadian Grain Commission standard. We confirm the exact grade specification against your requirements before shipping.
