Story of Clove: One of the Oldest Spices in world with Great Anti-bacterial Properties

Resembling small nails, the name clove is infact derived from the french word 'Clove' which means nail.

The clove story has the beginning in ancient times. Chinese records dating back to more than 2000 years mention about the custom of chewing of cloves to perfume the breath during audiences with the emperor. Before delving into more history, let us first know what a clove essentially is:

CLOVE CLOSE UP

To the man on the street, the actual source of clove is somewhat obscure. To him cloves seem to appear magically in a marked can on the grocer’s shelf. Resembling small nails, the name clove is in-fact derived from the french word ‘Clove’ which means nail. In reality, cloves are dried unopened bud of the clove tree, a tropical evergreen tree, whose botanical name is Syzygium aromatica. It is the native to the Moluccas, island of Eastern Indonesia, once known as Spice Islands.

EVENTFUL PAST OF CLOVES

For many centuries the Moluccas remained as the only source of this fascinating spice. The cloves of the Moluccas were traded in Asia long before Europeans heard of the spice island. The spice was introduced into Europe from the fourth to sixth century. By the Middle Ages, however cloves came to be widely used in Europe to preserve flavour and garnish food.

Clove trees

Clove trees are indigenous to the Moluccas. The natives ensured the proliferation of the clove trees in the region, and it was obligatory to plant a clove sapling to herald a child’s birth. It was firmly believed that if anything happened to the tree, the child’s future was doomed. So utmost care was taken to ensure the sapling grew up properly.

The Portuguese discovered the Spice Island and were pleasantly surprised to find the clove trees growing wild in the Island. The Portuguese held the clove trade in monopoly for some time. Later the Dutch took control over the Spice Islands. They undertook a comprehensive action plan to control the monopoly of the lucrative clove trade and proceeded systematically to destroy every clove tree that grew on the islands in the Moluccas except Ammonia and Tenant. The clove trees on these two islands were guarded zealously.  And hence the Dutch were successful in their endeavour. Scarcity of cloves naturally led to price hike.

For a considerable span of time around 1700s, it looked as if clove trees would never grow anywhere except these two islands. The stakes were high and other European nations attempted to break the Dutch stronghold on cloves. Eventually the French were successful in establishing smuggled clove saplings on the islands of Zanzibar and Pemba in latter half of the eighteenth century.

Cloves are now also produced in Brazil, Mauritius, Sumatra and Jamaica although the finest are said to come from Zanzibar and Madagascar. Cloves are now also produced in India in states of Karnataka, Tamil Nadu and Kerala.

CULTIVATION OF CLOVE TREES

The clove trees can be propagated either by seeds or by cuttings. Usually they are raised from seeds. After 1 or 2 years the young trees are replanted in the main plantation area. About five years later, they begin flowering twice a year. The planters handpick the buds in the late summer and again in winter. These buds are then sun dried on grass mats, which upon drying turns dark brown, the characteristic which we all are familiar with.

A clove tree comes to full maturity around twenty five years and may live up to 100 years or so. The annual crop yield of dried buds may be up to 34 kgs. The reason these trees are found only in specific places of the Earth is that it needs a very narrow range of temperature that should be neither below 10 degree Celsius nor above 28 degrees. Not only that, they require a warm, humid, tropical climate with lots of water around the year.

UNIQUE AROMA

All aromatic substances are sweet smelling, but there is something inexplicable about the clove’s aroma. Its aroma has been variously described as light, sweet, warm, spicy and fruity. It has subtle pervasive quality that is difficult to put across in words. Owing to this characteristic it mixes well with many other fragrances those of germanium, lavender, lemon, peppermint, sandalwood, basil, black pepper, cinnamon, cardamom, citronella, nutmeg, orange and rose.
