Aleppo pepper vs Urfa biber
The short answer
The two Turkish flake peppers, and they are opposites. Aleppo — pul biber, Maraş — is bright red, fruity and moderately hot, dried in the sun and salted or oiled lightly. Urfa is nearly black, sweated as well as dried, and tastes of raisin, chocolate and tobacco with a slow heat. Aleppo is the everyday table flake and Urfa the one used deliberately for its darkness.
Side by side
| Aleppo pepper | Urfa biber | |
|---|---|---|
| Botanical identity | Capsicum annuum L. | Capsicum annuum L. |
| Part used | fruit | fruit |
| Origin | The region around Aleppo in northern Syria and across the border into southern Turkey, where the cultivars and the processing both developed. Capsicum itself is American and reached the region after the Columbian exchange, so the spice as such is a few centuries old rather than ancient. | Capsicum is American; this cultivar and its curing method are from Şanlıurfa province in southeastern Türkiye, and the spice as such is a Turkish product of the post-Columbian period. |
| Flavour notes | fruity, sweet, earthy, smoky | raisin, smoky, chocolate, winey, sweet |
| Heat | 10000–25000 SHU (typically 15000 SHU) | 7500–30000 SHU (typically 15000 SHU) |
| Flavour | Moderately hot, fruity and slightly salty, with a warmth that arrives late and spreads rather than striking. The fruitiness is the distinguishing quality: it tastes of dried fruit and sun as much as of chilli, and that is what makes it usable in quantity where a hotter flake would not be. | Sweet, dark and slightly salty, with a late, low, rolling heat that arrives well after the flavour and stays modest. The salt is part of the product rather than an addition, which is worth knowing when seasoning a dish that carries a lot of it. |
| Aroma | Fruity and faintly raisiny, with a sun-dried sweetness and a light tomato-skin note. Very little sharpness — it does not catch the throat as ground cayenne does. | Raisin, tobacco and dark chocolate, with a faint smokiness that is not smoke — nothing is burned in the making of it — and a winey depth underneath. It smells more like a dried fruit than like a chilli. |
Can you swap them?
Substitution is directional: the answer is often different in each direction, and both are recorded.
Aleppo pepper
Good matchUse: 1× by volume — One for one. The two are comparable in heat and are both oily flakes, so the arithmetic holds better than for most chilli substitutions.
The two great Turkish and Levantine chilli flakes, made from different cultivars by different methods. Aleppo is bright red, fruity and slightly sharp; urfa is near-black, raisiny and dark. The heat level is comparable and the register is not, so a dish keeps its warmth and loses its depth. Aleppo is also less salty, so the seasoning needs adjusting.

Works for
- Kebabs, grilled meat and vegetables
- Finishing flakes on eggs, yoghurt and roasted vegetables
- Anywhere the heat rather than the darkness is the point
Does not work for
- Desserts, where urfa’s chocolate note is doing the work
- Dishes built specifically on the raisin-and-tobacco register
- Recipes relying on urfa’s salt content
Which should you buy?
Aleppo pepper
There is only really one form, and the buying decision is about quality rather than grind. Look for deep crimson, few seeds and a slightly moist flake, and treat a bone-dry bright-orange product with suspicion — it has either been kiln-dried or has sat in the light. Buy small quantities and keep the jar dark, because the colour and the fruitiness both go within months while the heat does not, and a faded Aleppo pepper is indistinguishable in use from ordinary chilli flakes. Do not pay a premium for the word Aleppo: most of the supply is Turkish Maraş and has been since 2011, and the good Turkish product is better than a poor jar with the right name on it.
