Profile

Cloves are the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum. They are native to the Maluku Islands, or Moluccas, in Indonesia, and are commonly used as a spice, flavoring, or fragrance in consumer products, such as toothpaste, soaps, or cosmetics. Cloves are available throughout the year owing to different harvest seasons across various countries.

Clove — Syzygium aromaticum — is the dried unopened flower bud of an evergreen tree native to the Maluku Islands, now grown mostly on Pemba and Zanzibar off the Tanzanian coast. Buds are hand-picked while still pink, then sun-dried until they harden into the dark brown nails that gave clou de girofle its name. Eugenol — 70 to 90 percent of the essential oil — delivers the unmistakable warm-medicinal bite. Cloves were briefly the most valuable spice in the world; Zanzibar's entire colonial economy was built on them. Today cloves anchor Indian biryanis, Moroccan ras el hanout, Indonesian kretek cigarettes, British bread sauce and pumpkin pie spice.

Process

01Year 1–15

The slow wait

Syzygium aromaticum is planted from seed in Pemba's red volcanic soil. Trees must reach 15 years before yielding a commercial crop worth harvesting.

02Jun–Jul & Nov–Dec

Two harvests per year

Zanzibar cloves flower twice annually. Pickers climb 8–10 m trees barefoot, harvesting buds before they open — an open flower means 30% less eugenol.

03Harvest, immediate

Separation from stems

Buds are separated from stems by hand within hours of picking. Stems and leaves are distilled separately for eugenol oil; buds are the premium product.

043–5 days

Coral-sand drying

Buds are spread on palm mats or directly on coral-sand roads in Pemba — the island's traditional method. Daily turning until moisture drops from 90% to under 12%.

05Your kitchen

Whole or freshly ground

For sauces: add 2 whole cloves to hot oil 60 seconds before onion — remove before serving. For desserts: grind immediately before use; ground cloves oxidise in 3 months.

Inside the berry

The molecules that make it taste like Kampot — and not like anything else.

Cloves are the densest natural source of eugenol on Earth. A single dried bud is up to 18% essential oil by weight, and that oil is overwhelmingly one molecule.

Story

Frequent questions

Pemba cloves (PDO-equivalent: 'Zanzibar cloves') consistently test at 80–90% eugenol — versus 72–78% for Indonesian cloves from Maluku or Sulawesi. The island's red volcanic soil, high rainfall, and sea-air humidity create conditions that concentrate essential oil in the bud. Pemba produces roughly 9,000 tonnes annually on just 984 km².
