Spices were first introduced by the Portuguese back in the 16th century, when they were transported over from colonies in Goa and Brazil. It wasn’t until the Omanis arrived, though, several hundred years later, that the spice trade truly thrived.

These days, the production of cloves is declining while tourism is skyrocketing, resulting in much of the spice industry turning towards plantation tours as a way to stay in business.
