The Kleinhettstedt Senfmühle is an ancient mill site in the Ilm valley near Weimar and Erfurt. The first written mention of it dates from the 16th century.
The Morgenroth family, which is now operating the mill into the 9th generation, bought the mill as a grain and oil mill in January 1732, and expanded the mill with other mill varieties such as gypsum, sawing, grains and mustard mills. Today, the mill’s mustards are among the premium mustards in Germany, not least of which is due to a mustard production process that is well-nigh extinct in the wake of mass production.
The secret lies in the processing of non-defatted certified eco-seed from the region, which is crushed in the mill over a smooth roll grinder and in the speed of the millstones, which in Kleinhettstedt rotate at only 55 rpm. Thus, the mustard oil is retained, whereas in industrial plants milling at about 3.000 rpm, it heats up and loses its aroma and flavour.
