All About Mustard

Mustard Seed

Mustard seed is G.S. Dunn's single raw material.

Mustard is best adapted to cool temperate climates. Currently over 80% of the world's condiment mustard seed is grown in the Prairie Provinces of Western Canada and North and South Dakota, USA. Other growing areas include eastern Europe, the UK, China and India.

Mustard has a short growing season of 90 - 110 days. In the northern hemisphere seeding typically occurs in May with harvest in August / September. The plant stands about 3-4 feet high when mature and has yellow flowers. After flowering, the seeds develop in pods until they are ready for harvest.

Once harvested the seeds are cleaned and graded according to Canadian Grain Commission (CGC) standards based on percentage of admixture, damaged or broken seeds, heated seeds, etc.

There are three commercially grown types of mustard seed:

Yellow (sometimes called white) Brassica Hirta
Oriental Brassica Juncea
Brown Brassica Juncea

Black mustard seed (Brassica Nigra) is grown in limited quantities but is not commercially available.

As with most crops, flavour and appearance is slightly affected by area of cultivation (climate, micro-climate, soil).
