MildSweet paprika: under 500 SHU
A sweet tin barely registers. New Mexico State University says the chile industry accepts at most 500 SHU for a paprika-type pepper1, and its own NuMex Sweet paprika measures 300 SHU. An average jalapeño rates about 5,0008, so that tin carries roughly a seventeenth of the burn, gram for gram.
Hot paprika is a different product, and you can tell from the label. Hungary's two protected paprikas sort their tins by capsaicin, and the top grades climb well past the sweet ceiling you know.
The specifications print capsaicin in milligrams per kilogram, which equals parts per million. Labs turn parts per million into SHU by multiplying by 169, so you can work each grade out yourself. The table does that for you; treat the results as estimates, since the limits count capsaicin alone.
| Paprika | Grade | Capsaicin limit | About this many SHU |
|---|---|---|---|
| Szegedi3 | Non-pungent (sweet) | up to 100 mg/kg | up to 1,600 |
| Szegedi3 | Moderately hot | 100–200 mg/kg | 1,600–3,200 |
| Szegedi3 | Hot | over 200 mg/kg | over 3,200 |
| Kalocsai4 | Moderately hot | 30–200 mg/kg | 480–3,200 |
| Kalocsai4 | Spicy | 200–500 mg/kg | 3,200–8,000 |
| Kalocsai4 | Hot | over 500 mg/kg | over 8,000 |
| Pimentón de Murcia5 | Extra and Primera | up to 0.003 % (30 mg/kg) | up to 480 |
Read the grade word on the tin: "sweet" and "hot" paprika can sit more than five times apart. A Kalocsa hot grade starts where a mild jalapeño sits, while the rules cap a Szeged sweet tin at 1,600 SHU.
Mild red Capsicum annuum, dried and ground. The US Food and Drug Administration defines paprika as the ground dried pod of mild capsicum2, and both Hungarian specifications name the long-podded var. Longum34.
So when you buy "paprika pepper", you buy a product more than a pod. NMSU's crop guide says paprika in the US is a product, not a pod type, so it can come from many types of C. annuum, and that the word simply means chile in Hungarian7. The NMSU Chile Pepper Institute puts it most broadly: any non-pungent chile, red at maturity, used as a spice or for color10. That is why the Spanish ñora, a small round pod, ends up in a tin with the same name as a long Hungarian one.
By resting, drying and stone grinding, and the Szegedi specification sets each step. Here is the path a pod takes before it reaches your shelf, with the numbers the rules give you.
The millstones do more than crush. As the paprika passes between them it warms up, and the warmth releases oil from the seeds and pigment from the skin, which then coat the granules and give the powder an even color3. Kalocsa caps that heat: its grinding has to stay below 80 °C4.

The finished powder has to pass a 0.5 mm sieve and may hold no additives3. If your supermarket tin feels gritty or looks dull, it probably skipped some of these steps.
Eater visits a Hungarian family farm in this video, so you can watch the hand picking and the turning of red pods into powder that the rules above describe.
Four European paprikas carry a protected name, two from Hungary and two from Spain. Each specification sets its own color floor, heat grades and drying method, so you can read a lot from the name on your tin.
| Paprika | Where | Drying | Heat grades | Color floor |
|---|---|---|---|---|
| Szegedi3 | Szeged area, Hungary | Sacks under eaves, drying chambers or belt dryers | Sweet, moderately hot, hot | ASTA 120 at packing |
| Kalocsai4 | Kalocsa area, across six Hungarian counties | Below 10 % moisture, surface at most 80 °C | Moderately hot, spicy, hot | ASTA 85 at best-before |
| Pimentón de Murcia5 | Murcia and nearby towns, south-east Spain | Sun or hot air | Sweet only | ASTA 120 (Extra), 90 (Primera) |
| Pimentón de la Vera6 | La Vera, northern Cáceres, Spain | Oak smoke for 10–15 days | Sweet, bittersweet, hot | Not compared here |
The big split for your cooking is smoke. Only La Vera dries over oak fires, so only La Vera tastes of smoke; the smoked paprika entry covers that style, and the Hungarian and Spanish paprikas side by side settles which suits a goulash and which a paella. Hungarian paprika also has its own flavor words in law: the Szegedi rules describe a sweet taste reminiscent of ripe, baked butternut squash3, and the Kalocsai rules an aroma like caramelized roasted seeds4.
The wider family of peppers behind those tins lives in the Hungarian peppers and Spanish peppers lists.
It scores the red. The American Spice Trade Association method measures extractable color, and NMSU says the industry expresses chile color in ASTA units12. A higher number means more pigment per spoonful, so less powder turns your sauce the same red.
Color is what you pay for, and the rules guard it. US labels may list paprika simply as "spice and coloring" unless they name it13, and the FDA allows it to color foods generally without batch certification2. NMSU lists sausages, cheeses and fruit gelatins among the foods it colors7, which is why you meet paprika in places that never taste of pepper.
New Mexico breeds most of them, and each release has a measured heat and color. If you grow paprika for your own powder, these are the figures to pick by.
| Cultivar | Released | Heat | Color |
|---|---|---|---|
| NuMex R Naky | 1985 | 260–760 SHU | 188 ASTA |
| NuMex Conquistador | 1989 | Under 10 ppm capsaicinoids (no heat) | Not given |
| NuMex Sweet | 1990 | 300 SHU | 157 ASTA |
| NuMex Garnet | 2004 | 160 SHU | 303 ASTA |
| NuMex R. Vince Hernandez | 2015 | Under the 500 SHU industry limit | 250 ASTA average |
Seed catalogs also sell Alma, Fehér Özön, Paprika Supreme and Elephant Ears as paprika peppers. We found no primary source with heat or color figures for any of them, so they get no numbers here; treat a packet's claim as the seller's word until a trial backs it.
Hungary's protected paprikas name their own seed lists. Szeged allows 19 state-recognised varieties, from Bíbor to Zuhatag, three of them marked hot3, and Kalocsa allows 174.
A little color chemistry for you, not a meal. FoodData Central lists ground paprika per 100 g; you'll rarely use more than a few grams, so we scaled the figures to 5 g, about a heaped spoonful, as an estimate.
Those carotenoids are the same pigments the ASTA score measures. FoodData Central also lists 18,900 µg of lutein and zeaxanthin per 100 g14, which is where the red and orange tones in your tin come from.
Heat, light and time break down the red pigment, and ground paprika loses it faster than whole pods. NMSU's postharvest guide spells out each cause12:
Causes of a dull tin, and the fix for each
A browned tin still tastes of paprika, just weaker. Use a little more of it in a stew where color matters less, and buy fresh for a dish where the red is the point.

Sweet paprika rarely makes your dish too hot; the usual problem you'll taste is a bitter or dusty taste and a color that turned rust-brown. Hot paprika is the one that can overshoot the heat. These kitchen fixes are our practical suggestions, not tested rules:
Taste for which problem you have
Burning heat means a hot grade went in; a bitter, dusty edge means too much powder or a scorched pan.
Make the pot bigger
Add more of the base (stock, tomato, beans or cream) so the same paprika spreads through more food.
Balance the bitterness
A spoonful of sour cream, a squeeze of lemon or a pinch of sugar softens a bitter, dusty taste.
Next time, add it to warm oil off the heat
The Szegedi rules show why oil matters: grinding warms the powder so its oil and pigment coat every grain. Stir paprika into warm fat away from the flame so it colors the oil without scorching.3
For cooking, pick the tin by what you want: Szegedi or Murcia sweet for color and a roasted pepper taste, a Kalocsa spicy grade when you want a gentle burn, and La Vera when the recipe asks for smoke. If your recipe says chili powder, that is a blend rather than a single pepper; the paprika and chili powder comparison shows what changes when you swap one for the other.
Yes, if you pick a mild red pod and dry it hard. NMSU's commercial method dries the fruit to 4 to 6 % moisture, grinds it, then brings it back up to 8 to 11 %7, the same window the Hungarian rules aim for. Your home version follows that order:
The full method, with temperatures and times for an oven or a dehydrator, is in the homemade paprika guide.
Match the tin to the job, since sweet, hot and smoked paprika do different work in your pan:
If you're out of paprika or want more heat, start with the paprika swap list, which gives amounts for each option.
Before you reach for the red jar beside it, check paprika against cayenne. Cayenne runs 25,000 to 50,000 SHU8, so a pinch of it replaces a spoonful of your sweet paprika.
