Vanilla is a spice derived from of the genus Vanilla, primarily obtained from pods of the flat-leaved vanilla ( V. planifolia).
Vanilla is not Autogamy, so pollination is required to make the plants produce the fruit from which the vanilla spice is obtained. In 1837, Belgian botanist Charles François Antoine Morren discovered this fact and pioneered a method of artificially pollinating the plant. The method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a 12-year-old slave who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollination. Hand-pollination allowed global cultivation of the plant. Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier. By the end of the 20th century, Albius was considered the true discoverer.
Three major species of vanilla currently are grown globally, all derived from a species originally found in Mesoamerica, including parts of modern-day Mexico. They are V. planifolia (syn. V. fragrans), grown on Madagascar, Réunion, and other tropical areas along the Indian Ocean; V. × tahitensis, grown in the South Pacific; and Vanilla pompona, found in the West Indies, Central America, and South America. The majority of the world's vanilla is the V. planifolia species, more commonly known as Bourbon vanilla (after the former name of Réunion, Île Bourbon) or Madagascar vanilla, which is produced in Madagascar and neighboring islands in the southwestern Indian Ocean, and in Indonesia. Madagascar's and Indonesia's cultivations produce two-thirds of the world's supply of vanilla.
Measured by weight, vanilla is the world's second-most expensive spice after saffron, because growing the vanilla seed pods is labor-intensive. Nevertheless, vanilla is widely used in both commercial and domestic baking, perfume production, and aromatherapy, as only small amounts are needed to impart its signature flavor and aroma.
Although the Totonacs are the most famously associated with human use of vanilla, it is speculated that the Olmecs, who also lived in the regions of wild vanilla growth thousands of years earlier, were one of the first people to use wild vanilla in cuisine.
Aztecs from the central highlands of Mexico invaded the Totonacs in 1427, developed a taste for the vanilla pods, and began using vanilla to flavor their foods and drinks, often mixing it with cocoa in a drink called " xocolatl" that later inspired modern hot chocolate. The fruit was named tlilxochitl, wrongly interpreted as "black flower" instead of the more probable "black pod" because the matured fruit shrivels and turns a dark color shortly after being picked. For the Aztecs, much like earlier Mesoamerican peoples before them, it is probable that vanilla was used to tame the otherwise bitter taste of Cocoa bean, as sugarcane was not harvested in these regions at the time and there were no other sweeteners available.
Hernán Cortés is credited with introducing both vanilla and chocolate to Europe in the 1520s. In Europe, vanilla was seen mostly as an additive to chocolate until the early 17th century when Hugh Morgan, a creative apothecary in the employ of Queen Elizabeth I, created chocolate-free, vanilla-flavored "sweetmeats". By the 18th century, the French were using vanilla to flavor ice cream.
Until the mid-19th century, Mexico was the chief producer of vanilla. One of Mexico's top producing regions was Veracruz, especially in the town of Papantla. By 1889, Mexican exports of vanilla exceeded 70,000 kilograms making the region one of the world leaders in vanilla production at the time. While vanilla trade was surging throughout Papantla, many farmers who owned land on which this commodity was growing would soon be subject to political shifts that led to those farmers having to pay rent. Protests of these shifts in policy led many to fight and die against the four tier hierarchy made up of Totonac caciques, ranchero clans, a hefty class of landowning labradores, and a bulging stratum of tenants, jornaleros, and ranch hands. In 1819, French entrepreneurs shipped vanilla fruits to the islands of Réunion and Mauritius in hopes of producing vanilla there. After 1841, when Edmond Albius discovered how to pollinate the flowers quickly by hand, the pods began to thrive. Soon, the tropical orchids were sent from Réunion to the Comoros Islands, Seychelles, and Madagascar, along with instructions for pollinating them. By 1898, Madagascar, Réunion, and the Comoros Islands produced 200 metric tons of vanilla beans, about 80% of world production in that year. According to the United Nations Food and Agriculture Organization 2019 data, Madagascar, followed by Indonesia, were the largest producers of vanilla in 2018.
After a tropical cyclone ravaged key croplands, the market price of vanilla rose sharply in the late 1970s and remained high through the early 1980s despite the introduction of Indonesian vanilla. In the mid-1980s, the cartel that had controlled vanilla prices and distribution since its creation in 1930 disbanded. Prices dropped 70% over the next few years, to nearly US$20 per kilogram; prices rose sharply again after Cyclone Hudah struck Madagascar in April 2000. The cyclone, political instability, and poor weather in the third year drove vanilla prices to US$500/kg in 2004, bringing new countries into the vanilla industry. A good crop, coupled with decreased demand caused by the production of imitation vanilla, pushed the market price down to the $40/kg range in the middle of 2005. By 2010, prices were down to $20/kg. Cyclone Enawo caused a similar spike to $500/kg in 2017.
An estimated 95% of "vanilla" products are artificially flavored with vanillin derived from lignin instead of vanilla fruits.
Although vanilla was domesticated in Mesoamerica and subsequently spread to the Old World, the use of an unidentified, Old World-endemic Vanilla species is attested in Canaan/Israel during the Middle Bronze Age and later. Traces of vanillin were found in wine jars in Jerusalem, which were used by the Judahite elite before the city was destroyed in 586 BCE.
Vanilla grows as a vine, climbing up an existing tree (also called a tutor), pole, or other support. It can be grown in a wood (on trees), in a plantation (on trees or poles), or in a "shader", in increasing orders of productivity. Its growth environment is referred to as its terroir, and includes not only the adjacent plants, but also the climate, geography, and local geology. Left alone, it will grow as high as possible on the support, with few flowers. Every year, growers fold the higher parts of the plant downward so the plant stays at heights accessible by a standing human. This also greatly stimulates flowering.
The distinctively flavored compounds are found in the fruit, which results from the pollination of the flower. These seed pods are roughly by , and brownish red to black when ripe. Inside of these pods is an oily liquid full of tiny seeds. One flower produces one fruit. V. planifolia flowers are hermaphroditic: they carry both male (anther) and female (pistil) organs. However, self-pollination is blocked by a membrane which separates those organs.
Despite various claims otherwise, the only pollinators definitively documented to date are orchid bees in the genus Eulaema and the Western honey bee. All commercial vanilla production takes place via hand pollination by humans.
The first vanilla orchid to flower in Europe was in the London collection of the Honourable Charles Greville in 1806. Cuttings from that plant went to Netherlands and Paris, from which the French first transplanted the vines to their overseas colonies. The vines grew, but would not fruit outside Mexico. The only known way to produce fruits is artificial pollination. Today, even in Mexico, hand pollination is used extensively. In 1837, botanist Charles François Antoine Morren began experimenting with hand pollination of Vanilla orchids in cultivation in Europe. Morren describes the process of artificially pollinating vanilla on p. 333: "En effet, aucun fruit n'a été produit que sur les cinquante-quatre fleurs auxquelles j'avais artificiellement communiqué le pollen. On enlève le tablier ou on le soulève, et on met en contact avec le stigmate une mass pollinique entière, ou seulement une partie de cette masse, car une seule de celles-ci, coupée en huit ou dix pièces, peut féconder autant de fleurs." (In effect, fruit has been produced only on fifty-four flowers to which I artificially communicated pollen. One removes the labellum or one raises it, and one places in contact with the stigma a complete mass of pollen i.e.,, or just a part of that mass, for just one of these, cut into eight or ten pieces, can fertilize as many flowers.) Available on-line at: Hortalia.org The method proved financially unworkable and was not deployed commercially. A few years later in 1841, a simple and efficient artificial hand-pollination method was developed by a 12-year-old slave named Edmond Albius on Réunion, a method still used today. Using a beveled sliver of bamboo, an agricultural worker lifts the membrane separating the anther and the Gynoecium, then, using the thumb, transfers the pollinia from the anther to the stigma. The flower, self-pollinated, will then produce a fruit. The vanilla flower lasts about one day, sometimes less, so growers have to inspect their plantations every day for open flowers, a labor-intensive task.
The fruit, a seed capsule, if left on the plant, ripens and opens at the end; as it dries, the natural phenol compounds crystallization, giving the fruits a diamond-dusted appearance, which the French call givre (hoarfrost). It then releases the distinctive vanilla smell. The fruit contains tiny, black seeds. In dishes prepared with whole natural vanilla, these seeds are recognizable as black specks. Both the pod and the seeds are used in cooking.
Like other orchids' seeds, vanilla seeds will not germinate without the presence of certain mycorrhizal fungi. Instead, growers reproduce the plant by cutting: they remove sections of the vine with six or more leaf nodes, a root opposite each leaf. The two lower leaves are removed, and this area is buried in loose soil at the base of support. The remaining upper roots cling to the support, and often grow down into the soil. Growth is rapid under good conditions.
The term French vanilla is often used to designate particular preparations with a strong vanilla aroma, containing vanilla grains and sometimes also containing eggs (especially egg yolks). The appellation originates from the French style of making vanilla ice cream with a custard base, using vanilla pods, cream, and egg yolks. Inclusion of vanilla varietals from any of the former French dependencies or overseas France may be a part of the flavoring. Alternatively, French vanilla is taken to refer to a vanilla-custard flavor.
Vanilla grows best in a hot, humid climate from sea level to an elevation of 1,500 m. The ideal climate has moderate rainfall, 1,500–3,000 mm, evenly distributed through 10 months of the year. Optimum temperatures for cultivation are during the day and during the night. Ideal humidity is around 80%, and under normal greenhouse conditions, it can be achieved by an evaporative cooler. However, since greenhouse vanilla is grown near the equator and under polymer (HDPE) netting (shading of 50%), this humidity can be achieved by the environment. Most successful vanilla growing and processing is done in the region within 10 to 20° of the equator.
Soils for vanilla cultivation should be loose, with high organic matter content and loamy texture. They must be well drained, and a slight slope helps in this condition. Soil pH has not been well documented, but some researchers have indicated an optimum soil pH around 5.3.Berninger, F., Salas, E., 2003. "Biomass dynamics of Erythrina lanceolata as influenced by shoot-pruning intensity in Costa Rica." Agro-forestry Systems, 57:19–28. Mulch is very important for proper growth of the vine, and a considerable portion of mulch should be placed in the base of the vine. Fertilization varies with soil conditions, but general recommendations are: 40 to 60 g of N, 20 to 30 g of P2O5 and 60 to 100 g of K2O should be applied to each plant per year besides organic manures, such as vermicompost, oil cakes, poultry manure, and wood ash. Foliar applications are also good for vanilla, and a solution of 1% NPK (17:17:17) can be sprayed on the plant once a month. Vanilla requires organic matter, so three or four applications of mulch a year are adequate for the plant.
Before planting the cuttings, trees to support the vine must be planted at least three months before sowing the cuttings. Pits of 30 × 30 × 30 cm are dug away from the tree and filled with farm yard manure (vermicompost), sand and top soil mixed well. An average of 2000 cuttings can be planted per hectare (2.5 acres). One important consideration is that when planting the cuttings from the base, four leaves should be pruned and the pruned basal point must be pressed into the soil in a way such that the nodes are in close contact with the soil, and are placed at a depth of . The top portion of the cutting is tied to the tree using natural fibers such as banana or hemp.
Biological control of the spread of such diseases can be managed by applying to the soil Trichoderma ( per plant in the rhizosphere) and foliar application of pseudomonas (0.2%). Mosaic virus, leaf curl, and cymbidium mosaic potexvirus are the common viral diseases. These diseases are transmitted through the sap, so affected plants must be destroyed. The insect pests of vanilla include beetles and weevils that attack the flower, caterpillars, snakes, and slugs that damage the tender parts of shoot, flower buds, and immature fruit, and grasshoppers that affect cutting shoot tips. If organic agriculture is practiced, insecticides are avoided, and mechanical measures are adopted for pest management. Most of these practices are implemented under greenhouse cultivation, since such field conditions are very difficult to achieve.
The orchid species Leptotes bicolor is used as a natural vanilla replacement in Paraguay and southern Brazil.
In 1996 the US Food and Drug Administration cautioned that some vanilla products sold in Mexico were made from the cheaper tonka bean which as well as vanillin also contains the toxin coumarin. They advised consumers to always check the ingredients label and avoid suspiciously cheap products.
If the fruit is more than in length, it is categorized as first-quality. The largest fruits greater than and up to as much as are usually reserved for the gourmet vanilla market, for sale to top chefs and restaurants. If the fruits are between 10 and 15 cm long, pods are in the second-quality category, and fruits less than in length are in the third-quality category. Each fruit contains thousands of tiny black vanilla seeds. Vanilla fruit yield depends on the care and management given to the hanging and fruiting vines. Any practice directed to stimulate aerial root production has a direct effect on vine productivity. A five-year-old vine can produce between of pods, and this production can increase up to after a few years. The harvested green fruit can be commercialized as such or cured to get a better market price.
Testing has shown mechanical disruption of fruit tissues can cause curing processes, Methods of dehydrating and curing vanilla fruit US Patent 2,621,127 including the degeneration of glucovanillin to vanillin, so the reasoning goes that disrupting the tissues and cells of the fruit allow enzymes and enzyme substrates to interact.
Hot-water killing may consist of dipping the pods in hot water () for three minutes, or at for 10 seconds. In scratch killing, fruits are scratched along their length. Frozen or quick-frozen fruits must be thawed again for the subsequent sweating stage. Tied in bundles and rolled in blankets, fruits may be placed in an oven at for 36 to 48 hours. Exposing the fruits to sunlight until they turn brown, a method originating in Mexico, was practiced by the Aztecs.
Higher-grade fruits command higher prices in the market. However, because grade is so dependent on visual appearance and moisture content, fruits with the highest grade do not necessarily contain the highest concentration of characteristic flavor molecules such as vanillin, (2025). 9783905745191, Zürich University of Applied Sciences. ISBN 9783905745191 and are not necessarily the most flavorful.

Vanilla flavoring in food may be achieved by adding vanilla extract or by cooking vanilla pods in the liquid preparation. A stronger aroma may be attained if the pods are split in two, exposing more of a pod's surface area to the liquid. In this case, the pods' seeds are mixed into the preparation. Natural vanilla gives a brown or yellow color to preparations, depending on the concentration. Good-quality vanilla has a strong, aromatic flavor, but food with small amounts of low-quality vanilla or artificial vanilla-like flavorings are far more common, since true vanilla is much more expensive.
Regarded as the world's most popular aroma and flavor, (2025). 9781845934057, CABI. ISBN 9781845934057 vanilla is a widely used aroma and flavor compound for foods, beverages and cosmetics, as indicated by its popularity as an ice cream flavor (as of 2004, around half of vanilla flavor consumed in the US was eaten in ice cream). Although vanilla is a prized flavoring agent on its own, it is also used to enhance the flavor of other substances, to which its own flavor is often complementary, such as chocolate, custard, caramel, coffee, and others. Vanilla is a common ingredient in Western sweet baked goods, such as cookies and . Despite the expense, vanilla is highly valued for its flavor.
The food industry uses vanillin as less-expensive substitutes for real vanilla. Ethyl vanillin is more expensive, but has a stronger note. Cook's Illustrated ran several taste tests pitting vanilla against vanillin in baked goods and other applications, and to the consternation of the magazine editors, tasters could not differentiate the flavor of vanillin from vanilla; however, for the case of vanilla ice cream, natural vanilla won out. A more recent and thorough test by the same group produced a more interesting variety of results; namely, high-quality artificial vanilla flavoring is best for cookies, while high-quality real vanilla is slightly better for cakes and significantly better for unheated or lightly heated foods.
The liquid extracted from vanilla pods was once believed to have medical properties, helping with various stomach ailments.
