Both Sidr Honeys are from Yemen, but one is harvested from Hadramout and the other from Usimate; hence the names are Hadrami and Usimi. When it comes to taste and qualities, the difference is very slim between them, yet it is important to note that Usimate is a high altitude and mostly green region, and Hadramout is a low altitude and mostly dry (desert-like).
The main difference between these two products is that we pack the Usimi Sidr honey jar with honeycomb chunks; so if you love honeycomb, you might enjoy Usimi jar more, but if you enjoy your honey pure, then you can stick to the Hadrami jar :)
Other than this, both are very special when it comes to taste and both are known for their potent therapeutic qualities!
