Whole spice · Syzygium aromaticum (L.) Merr. & L.M.Perry
Specification and grades
Clove is a hand-harvested crop: the unopened flower bud is picked before it blooms, then sun-dried until it takes its dark brown colour. India grows a small but genuinely high-oil crop in the Western Ghats and the far south, and the value sits almost entirely in volatile oil and in how clean the lot is of stems and headless buds. We buy hand-picked selected material, screen it again before packing, and quote against a declared oil minimum confirmed on a third-party certificate of analysis.
