Almost every peppercorn you've ever eaten comes from a single plant. The colour on the label isn't a different species but a different moment in the fruit's life and a different way of processing it. Here is what each one actually is, how it tastes and when to reach for it.
Did you know that black, white, green and red peppercorns are all the same fruit - the berry of Piper nigrum, which is a tropical climbing vine native to the Malabar coast of southern India. What separates the varieties is at what stage the berry is picked and how it is processed afterwards.
Just as coffee beans roasted at different temperatures will give you very different results, pepper works the same way, except the variable is ripeness rather than roast.
Pink peppercorns are completely different as they aren't a true pepper at all, but more on that below.

One plant makes every colour
Peppercorns or Piper nigrum, grow as small round berries in long clusters, like bunches of tiny grapes, on a climbing vine. The berries start off green and as they ripen on the vine, turn from yellow, to orange and then red.
Growers will harvest them at different phases as the peppercorns change colour and process the berries in different ways. The differences in colour and processing are what determine the flavour profile and character of the pepper.
The longer a berry stays on the vine, the riper and fruitier it becomes. The processing then decides everything else from if the skin stays on, to whether it is fermented, dried in the sun or preserved in brine.
The colours of pepper
Pepper is sold according to colour, there are 4 types with different uses:
Green peppercorns
Green peppercorns are unripened berries - picked while still young and green. This is the mildest pepper with a fresh, vegetal and slightly citrus flavour.
Freshly picked raw berries spoil fast but are particularly prized in Vietnamese, Thai and French cuisines. They are used in the classic French steak au poivre vert, for creamy sauces and go well with poultry and fish.
The rest are freeze-dried, air-dried or more commonly, pickled in brine or vinegar.
Black peppercorns
Black peppercorns - the most commonly used pepper starts off as green peppercorns. They are picked before they ripen and turn red, then blanched for 10 minutes. This triggers an enzymatic reaction causing their skin to shrivel and darken but also cleans them, removes surface mold-causing microbes and prepares them for the drying process. They are then dried in the sun 7 to 10 days or mechanically over 24 hours.
The skin is where much of the flavour lives. It is rich in piperine, the compound behind pepper's heat which is why black pepper is the strongest and most pungent of the peppers. It keeps the vegetal note from when it was green but once processed, develops a warmer, deeper and far punchier heat.
Black pepper is an everyday workhorse, it can be used in zigni, braised cabbage, spaghetti alla nerano, watermelon salad, sauces and baharat spice mix.
Red peppercorns
Red peppercorns are fully ripe berries. When they are left on the vine they ripen to red. These are fruitier and slightly sweeter than black pepper with a rounder, less aggressive heat.
They are the most perishable as the higher moisture and sugar content means they don't keep as long as black peppercorns. The short shelf life and as they are considered a specialist ingredient, they are rarely found in supermarkets.
Red peppercorns must not to be confused with pink peppercorns; below you will see why they are not the same thing.
White peppercorns
White peppercorns are ripe berries with the skin removed. They start off as ripe red berries which are then soaked in water for several days. This process is called water retting, where naturally occurring microorganisms produce enzymes which break down the outer skin of the berries. They are washed to reveal a white seed and then dried.
As the fiery piperine-rich skin is removed, white pepper is milder and less pungent than black pepper, with an earthy, floral and slightly fermented flavour.
Cooks prefer to use white pepper for a milder heat or when they don't want black specks in a cream sauce, mashed potato, potato salad and light coloured soups. In Chinese cooking, white pepper is used a great deal in marinades and stir-fries.
Yellow and orange
You may have seen peppercorns described as yellow or orange. These are not different types of pepper, but partially ripened berries as they ripen from green to red on the vine. They are rarely found in stores and there is little demand for them as they do not have their own flavour profile.
Pink peppercorns
Pink peppercorns are not a true pepper, they don't come from Piper nigrum at all. They are the dried berries of the Peruvian pepper tree (Schinus molle), an entirely unrelated South American plant.

Allergy Advice
If you or a guest has a tree-nut allergy - unlike other peppercorns mentioned here, pink peppercorns are related to cashews and pistachios and have occasionally triggered reactions in sensitive people.
They are more delicate than other peppers, with a skin which flakes off, covering a soft and sticky seed. Their flavour is sweet, mildly fruity and only faintly peppery. They are prized for their rosy colour and their flavour.
Their delicate flavour makes them ideal for seafood and cream sauces such as Sauce aux Poivre Rose, cheeses, vinaigrettes, garnishes and desserts.
Where does the best pepper come from?
The origin of pepper, where it is grown, the soil and the climate, affects the flavour in the same way as wine or coffee. Peppers grown in different soils at various times of the year will have a range of flavours, pungencies and aromas.
A handful of regions are especially prized for the best peppercorns, these are:
Malabar Coast, India - this 525 mile coastal strip in southwest India is the historic home of pepper and still the source of two of the most sought-after grades, both prized for their flavour complexity compared to other varieties. They are:
- Malabar - Malabar pepper, from the Kerala coast of India, the birthplace of pepper, is robust, warm and resinous with citrus aromas and a medium-hot, straightforward heat. It is a reliable, versatile workhorse in professional kitchens, excellent for steaks, stocks and stews.
- Tellicherry - Tellicherry, a premium grade of Malabar pepper with larger berries allowed to ripen longer, adds more sweetness and complexity and is widely considered the finest Indian pepper.
Kampot, Cambodia - Kampot pepper is highly regarded by chefs for its delicate, aromatic and complex flavour, with its distinctive floral and jasmine notes, subtle fruity sweetness and clean, lingering heat that enhances rather than dominates.
As heat destroys its unique volatile aromatic oils it is usually used as a finishing pepper over steaks, seafood or even chocolate desserts, but can also be used in cooking when used in larger quantities, for example in Kampot Crab.
Kampot was awarded EU Protected Geographical Indication status in 2016, as a mark of quality tied directly to the region's volcanic soil and climate.
Sarawak, Malaysia - these peppercorns are grown in the rainforests of Malaysian Borneo, they are one of the world's most versatile and well-regarded culinary peppers.
PGI protected and are known for their fruity aroma and warm, woody notes; they are a natural fit for curries. Its flavour is notably milder than Indian varieties. It is fruity and earthy with subtle citrus notes and a gentle, warming heat that builds slowly rather than striking immediately. White Sarawak, is particularly prized for its mild, almost sweet character, making it the preferred choice for delicate fish dishes, cream sauces, and egg preparations where stronger peppers would overpower.
Regulated and certified by the Malaysian Pepper Board (MPB), authentic Sarawak pepper meets strict food safety and quality standards, though mislabelling is common, so it is important to check for the MPB certification. Its sustainable farming credentials are strong, with the WWF highlighting Borneo pepper cultivation as a model of environmentally responsible spice production.
It sits between the robust heat of Malabar and the aromatic finesse of Kampot. Sarawak offers chefs a reliably refined, mid-range pepper with genuine terroir character. It is usually sold in mixed peppercorn blends and an increasingly sought after ingredient in European and North American fine dining.
Lampong, Indonesia - cultivated in volcanic soil, they are fruity, slightly smoky with a fiery kick; perfect for meats and hard cheeses.
It is one of the most widely used black peppers in both the UK and US, where it dominates everyday commercial supply. It is significantly hotter and more pungent than both Sarawak and Malabar, with a clean, bold, piney and resinous character alongside hints of citrus, wood, and mint. Its small, dense berries contain notably high levels of piperine (the compound responsible for pepper's heat) making it one of the most intensely spicy black peppers available.
Lampong is valued primarily for its intense heat rather than complexity and it is favoured in professional kitchens for marinades, stocks, stews, pickling, and robust meat preparations. Despite its widespread use, its aromatic profile is less sophisticated than the premium terroir-driven varieties and chefs seeking nuance and complexity would rather use Sarawak, Tellicherry, or Kampot in its place. Authentic Lampong pepper carries a Geographical Indication certification, though enforcement varies and mislabelling remains a concern in the market.
Phu Quoc, Vietnam - Vietman is the world's largest exporter of peppercorns,
producing huge quantities of black pepper valued for its intense heat, strong aromatics and lower cost. The best pepper is from the Island of Phu Quoc, grown in mineral rich laterite soil under a tropical monsoon climate with strong sunlight and sea breezes. These conditions produce a higher concentration of essential oils compared to other mainland Vietnamese varieties, with more aromatic flavour of citrus, eucalyptus and herbal notes and intense heat.
Phu Quoc's red peppercorns develop a sweet, citrusy heat comparable to Kampot, while its fresh green peppercorns are used locally in a Vietnamese twist on steak au poivre.
How to use peppercorns
Whole, freshly cracked pepper tastes much better then pre-ground pepper. After grinding, pepper starts losing its volatile oils and aroma so it is best to store them whole until you are ready to use them. Whole peppercorns keep them locked in until the moment you crack them.
Here are the different ways to use peppercorns:
Toast dried peppercorns first - for dried peppercorns, dry-roast them gently in a pan over low heat for 30 to 60 seconds before grinding or adding to a dish. The gentle heat releases aromatic oils and deepens the flavour. Leave them cool before cracking or grinding.
Fresh (brined) green peppercorns can go in whole, either straight into sauces, or crushed into a marinade.
Know which colour pepper to use in the dish: use black pepper for a deep complex heat; white for light coloured dishes for mild kick and if you don't want specks; green for pepper's delicate flavour without heat; red where you want fruitiness.
Do peppercorns go bad?
Fresh raw green peppercorns on their stems will keep for around a week in the crisper drawer of fridge and possibly longer if they are wrapped in a damp kitchen cloth. Throw them away if you see signs of spoilage such as: fuzzy mold, if they have become slimy or shrivelled and black, or they have a musty fermenting smell.
Brined green peppercorns, once opened will keep in the fridge for around a week, use them as you would any fresh preserved ingredient.
Whole dried peppercorns will not spoil in a dangerous sense but they will lose their aroma and potency over time. Store them whole in a sealed container and keep in a cool place - they will keep their flavour for years.
Ground pepper is different as it will start losing flavour within weeks of grinding, even if stored in a sealed container.
How to store peppercorns
For best flavour, always buy whole peppercorns and only grind as much as you need at a time.
Store them in a sealed container away from heat and light. Keep them in a cupboard rather than on a window-sill or above the stove. Light and heat will quickly degrade the volatile oils, reducing their flavour.
FAQ
Yes, black, white, green and red peppercorns all come from the same plant called the Piper nigrum. The difference is when the berry is picked and how it is processed. Green is unripe and preserved fresh; black is unripe, boiled and dried; red is fully ripe; white is a ripe berry with the skin removed.
No, pink peppercorns come from the Peruvian pepper tree, the Schinus molle, a completely different and unrelated plant. They are sweet, fruity and only mildly peppery. They are also related to cashews, so people with tree-nut allergies should be cautious with them.
Both come from Piper nigrum, but white pepper is made from fully ripe berries with the spicy outer skin removed and then dried. Removing the skin makes it milder and smoother than black pepper. White pepper has an earthy note and no black specks, which is why it is used for white dishes and Chinese cooking.
Black pepper is the most pungent of the common colours, because the piperine-rich skin is left on and concentrated during the drying process. Green is mildest, red is fruity and moderate, while white has a mild but sharp background heat.
Despite its name, Sichuan peppercorns are not a pepper at all. They are the dried husks of the prickly ash shrub, a member of the citrus family (the seeds are discarded). They give a citrusy aroma and create the distinctive tingling, numbing sensation on the tongue known as málà in Chinese cooking.
Yes, a quick dry-roast of dried peppercorns in a pan over low heat for 30-60 seconds releases the aromatic oils and deepens the flavour. Let them cool before grinding.
Old whole dried peppercorns won't make you ill, instead they gradually lose their aroma and potency over the months and years. When stored whole in an airtight jar away from light and heat, they keep their flavour far longer than store bought ground pepper which only retains its flavour for a few weeks.
