Yes, the taste of black cumin oil can vary because the origin of the plant differs, which can affect its taste and smell. To best understand why the taste of black cumin varies, we would compare it to red wine.
Namely, even with the same grape variety in the same vineyard, the quality, taste and aroma of the wine can differ from year to year. The same is true of the Nigella sativa plant, from which black cumin oil is obtained.

Probotanic checks the quality of the oil in every production batch, and we are committed to offering oil of the highest quality.
