The aroma components of dill from different habitats are very different. In terms of flavor, German dill seed is the best, and its main aroma components are carvone >: 55%, limonene, dihydrocarvonol, p-methylpropene, dilfuran, myrcene, α-phellandrene and so on.

The aroma of dill seeds is similar to that of caraway, with strong sweetness and spicy taste, but sharper than caraway and less pleasant. The taste is similar to that of coriander, with a slightly pungent feeling. Dill seed essential oil is fresh, sweet and spicy, like caraway, with the aroma of fruit and vanilla. Pay attention to the difference of essential oil made from dill grass, which has obvious grass fragrance and mint aftertaste. Dill seed oil resin tastes the same as before.
