Český kmín are caraway seeds of the "Carum carvi L - fructus" species produced in the Czech Republic on loamy, sandy and clay soils since the first half of the 19th century. The seeds are well-formed and developed, healthy, elongated and slightly bent.
They are bright to dark brown in colour and have a spicy flavour typical of caraway. Their uniqueness is due to the fact that they have a high content of aromatic oil (from 3 to 5 %) and are harvested when they are well matured. Carvone content in the seeds is higher than 50%, with healing and antiseptic properties.
