Kampot Pepper: Cambodia’s Protected Black Pepper, Its Flavor and History

By Cambodia’s own account, almost all of the pepper eaten in France in the 1920s came from one region of Indochina: the provinces of Kampot and Kep.¹ Kampot pepper is black pepper, Piper nigrum, from that small patch of southern Cambodia, and its farms almost completely vanished under the Khmer Rouge before producer families brought it back.¹ It’s also one of the few peppers with a legally protected name. Cambodia registered it as a geographical indication in 2010, and the European Union entered “Poivre de Kampot” in its register of protected geographical indications in 2016.²¹

What the protected name covers

The EU registration rests on a product specification Cambodia submitted. It defines four products from the same vine, picked at different stages:¹

For comparison, the international Codex standard for whole black pepper sets a minimum bulk density of 550 g/L for its top grade, 500 g/L for Grade II and 400 g/L for Grade III.³ The specification sets no piperine or essential-oil minimums. Its measurable quality criteria are size, density and defect tolerances.¹

Where. The area takes in Kampong Trach, Dan Tong, Toeuk Chhou, Chhouk and Kampot City in Kampot province, and Kep City and Damnak Chang Aeur in Kep province. Rain there tops 2,000 mm a year, and plots sit on hills or at the foot of mountains for drainage.¹

How it must be grown. Only two varieties are allowed, Kamchay and Lampong, and planting material has to come from the defined area. Only natural fertilizers can be used, and herbicides are banned. Chemical insecticides are allowed only when natural means fail, and only those in WHO hazard classes II and III. Vines must stand at least 1.80 m apart, the harvest is by hand, and the pepper dries on nylon, mats or tents above cement areas before sorting removes foreign matter. The specification names an inter-branch body, the Kampot Pepper Promotion Association (KPPA), that brings together the producers and others who work with the product.¹

The Lampong variety shares its name with the Indonesian pepper sold as Lampong pepper, which comes from Lampung province in Sumatra.

Flavor

The specification describes Kampot pepper’s pungency as strong “but not ‘burning’”, with an aromatic intensity.¹ Here’s how it describes each type:¹

• Green: a fresh citrus flavor, less spicy than the dried types.
• Black: deeper, stronger and “vaguely floral,” with hints of flower, eucalyptus and mint.
• Red: sweeter and less spicy than black.
• White: notes of fresh grass and lime.

Keep in mind these are the producers’ own descriptions, submitted with their application, not results from a published comparison with other peppers. We didn’t find any study measuring Kampot pepper’s piperine or essential oil against other origins. The heat in any black pepper comes from piperine. Katzer’s Spice Pages puts piperine and related compounds at 5% or more of black pepper, roughly half of it piperine itself.⁴

History

The product specification tells the pepper’s history the way Cambodia presented it to the EU:¹

• 13th century. Pepper is mentioned in the reports of the Chinese explorer Zhou Daguan, spelled Tchéou Ta Kouan in the document.
• The colonial period. The account then jumps to the arrival of French colonists. The pepper became well known, especially in France and the rest of Europe, and in the 1920s almost all of the pepper eaten in France came from “that region of Indochina.”
• Peak output. Production reached up to 8,000 tons a year and later settled at around 3,000 tons a year.
• Collapse. Production came to “a dramatic stop” under the Khmer Rouge regime and the civil war, and pepper farms almost completely vanished.
• Revival. Producer families returned to their ancestral land in Kampot and Kep and started growing pepper again with traditional methods.

Two dates round out the record. Protection in Cambodia was granted on 2 April 2010,¹ and the EU registered the name by Implementing Regulation (EU) 2016/222 of 5 February 2016, after Cambodia’s application was published in the Official Journal on 13 August 2015 and drew no opposition.²

Several details often repeated about Kampot pepper couldn’t be confirmed in any source we looked at: that it’s been grown in the region for more than 1,000 years, that the Aceh War in Sumatra pushed production to Cambodia, that only 4 tons a year were harvested in the late 1990s, and that the revival started from vines found growing wild. We’ve left them out.

How to use it

Use Kampot pepper anywhere you’d use good black pepper, but where you can actually taste it: ground over finished dishes, not simmered for hours. Its citrus and floral notes suit seafood, eggs, fruit and simple grilled meats. In Cambodia itself, Katzer says, black pepper goes into a widespread table condiment, tik marij.⁴

• Green Kampot pepper, fresh or brined, is a different ingredient from dried pepper. See green peppercorns.
• Red Kampot pepper is fully ripe pepper, dried. Don’t confuse it with pink pepper.
• White Kampot pepper suits pale sauces. See white peppercorns and white vs. black pepper.

If a dish ends up over-peppered, see too much pepper.

Buying and quality

The name is protected in the EU, so pepper sold there as Poivre de Kampot has to meet the specification above.²¹ Outside the EU, look for a stated origin in Kampot or Kep and, where it’s offered, the PGI name or producer association. Whole berries should be uniform in size, with little dust or broken bits.

Storage

Keep whole peppercorns airtight, away from light and heat, and grind as you need them. We didn’t find a shelf-life figure for whole or ground black pepper from a regulator or standards body.

Nutrition and health

USDA’s entry for ground black pepper (not Kampot specifically) lists 164 µg of vitamin K per 100 g, and a tablespoon as 6.9 g.⁵ That works out to about 11 µg of vitamin K per tablespoon, roughly 9% of the 120 µg Daily Value,⁶ and about 0.67 mg of iron, roughly 4% of the Daily Value.⁵⁶ A tablespoon is far more pepper than most people put in a dish, so in practice pepper adds little to your diet.

Britannica notes that pepper has a limited use in medicine as a carminative, to relieve gas.⁷ None of the sources we reviewed supports claims that Kampot pepper prevents cancer or improves digestion, and we’re not making them. For what’s known about piperine, see black pepper.

Safety

EU law caps aflatoxin B1 at 5.0 µg/kg and total aflatoxins at 10.0 µg/kg in pepper, defined as the fruits of Piper species, black and white pepper included.⁸ Those limits apply to Kampot pepper sold in the EU just as they do to any pepper.
