Black pepper's heat comes from a compound called piperine, while pul biber and red pepper's heat comes from an entirely different compound called capsaicin; because these two compounds trigger different receptors, the sensation of heat they leave in the mouth is perceived quite differently. Black pepper's heat is sharper and more immediate, while chilli heat spreads and lingers.
How is black pepper's heat measured?
Since it contains no capsaicin, black pepper doesn't register on the Scoville scale, the standard unit used to measure chilli heat; its piperine content varies by peppercorn and grind coarseness, and coarsely ground black pepper generally leaves a sharper bite than finely ground. White pepper, made from the same plant's peeled berry, carries a slightly milder heat than black pepper.
How do pul biber and red pepper compare?
Pul biber generally sits around 500-1,500 Scoville units and is the most commonly used medium-heat pepper in Turkish cooking; red pepper powder can range from mild (0 Scoville, as in sweet red pepper) to quite hot, depending on the pepper variety used. So the term "red pepper" alone doesn't reliably indicate heat level — checking the pack for "hot" or "sweet" is necessary.
Heat tolerance varies enormously from person to person; an amount of pul biber one person finds mildly spicy can feel genuinely fiery to another. That difference depends on the density of capsaicin receptors on a person's tongue and their habitual exposure to spicy food — tolerance can build over time with regular chilli eating.
Heat resistance under cooking differs too: capsaicin is fairly heat-stable and largely holds onto its heat through long cooking, and some recipes that bloom pul biber in oil can even intensify its heat. Piperine evaporates faster with heat, which is why black pepper is usually added at the end of cooking to preserve its aroma.
There's a practical way to tone down heat: since capsaicin is fat-soluble, adding a fatty ingredient like milk, yoghurt or butter to an overly spicy dish eases the heat far more effectively than drinking water. Water only spreads capsaicin around the mouth — it doesn't actually dissolve it.
How white pepper is used follows from this difference too: it's favoured in light-coloured sauces and soups so black pepper's dark flecks don't show, but since it's a touch milder than black pepper, the amount should be adjusted accordingly. Pink peppercorns are botanically unrelated to black pepper and carry a fruitier, mildly sweet aroma, with noticeably less heat.
Green peppercorns, meanwhile, are unripe black peppercorns; sold fresh or pickled, they leave a sharper, more vegetal taste than the ripe berry. That range shows how even different maturity and processing stages of the very same peppercorn plant can shift how its heat and aroma are perceived.

Acı toleransım düşük olduğu hâlde tarifte yazan miktar kadar pul biber koydum, metinde de dendiği gibi gerçekten kalıcı ve yayılan bir acılık bıraktı; su içmek hiç işe yaramadı, sonunda yoğurtla dengelemek zorunda kaldım.
