All mustard is made in relatively the same way. The seed must be crushed, its hull and bran sifted out or not depending on type of mustard being made. It then may or may not go through further grinding and crushing. A liquid such as water, wine, vinegar, beer, or a combination of several of these liquids is added, along with seasonings and perhaps other flavorings. The mustard is mixed, in some cases simmered, and then cooled. Some mustard is aged in large containers before it is bottled and shipped to stores and customer.
