Frank's RedHot Original Sauce measures 450 Scoville Heat Units (SHU), sitting comfortably on the mild end of the spice spectrum. If you've ever wondered why this iconic condiment adds more tang than burn, the answer lies in its ingredient ratio and the natural capsaicin limits of aged cayenne peppers. While raw cayenne peppers range from 30,000 to 50,000 SHU, heavy dilution with distilled vinegar, water, and garlic drastically drops the final heat output.
Understanding how this classic hot sauce measures up against other condiments helps explain its massive culinary versatility. It's designed to enhance flavor rather than overwhelm your palate, making it the foundational element of the original Buffalo wing sauce created in New York back in 1964.
How the Scoville Scale Measures Frank's RedHot
Wilbur Scoville invented his famous scale in 1912 to measure capsaicin concentration—the chemical compound that gives chili peppers their fiery kick. The original test used human tasters to determine how much sugar-water dilution was needed until a pepper extract lost its heat burn entirely. Modern testing relies on high-performance liquid chromatography (HPLC) to measure capsaicinoids directly, converting the results into SHU.
Because Frank's RedHot blends a mash of aged red cayenne peppers with vinegar, salt, and garlic, the pure capsaicin is diluted across a large liquid volume. At 450 SHU, the sauce provides a warm, warming tang instead of a lingering burn. This low threshold means most people can douse their food generously without needing a glass of milk.

Frank's RedHot Product Lineup Heat Comparison
Not all variants in the product family share the same mild rating. The brand has expanded significantly over the decades to cater to different tolerance levels.
- Frank's RedHot Original (450 SHU): The flagship recipe featuring aged cayenne peppers, vinegar, water, salt, and garlic powder.
- Frank's RedHot Wings Sauce (450 to 500 SHU): Pre-blended with butter flavor and natural gums to cling directly to fried chicken.
- Frank's RedHot Sweet Chili (1,000 to 2,000 SHU): Blends mild chili notes with sugar and garlic for a sticky, sweet profile.
- Frank's RedHot XTRA Hot (2,000 SHU): Packs roughly four times the heat of the original by adjusting the pepper concentration and capsaicin load.
- Frank's RedHot Stingin' Honey Garlic (approx. 500 SHU): Combines the original base with real honey and savory garlic for a balanced, sweet finish.
How Frank's Compares to Other Popular Hot Sauces
To put 450 SHU into perspective, it helps to look at where it sits alongside everyday tabletop condiments. Most mainstream Louisiana-style hot sauces sit well above the baseline set by Frank's.
- Tabasco Original: Measures around 2,500 to 5,000 SHU, driven by heavy vinegar and tabasco peppers.
- Cholula Original: Ranges from 1,000 to 2,000 SHU using arbol and piquin peppers.
- Sriracha (Huy Fong): Hits roughly 1,000 to 2,500 SHU using red jalapeños.
While Tabasco and Cholula lean heavily into sharper pepper profiles, Frank's prioritizes a balanced pH and high acidity. This formulation highlights the savory, earthy notes of the cayenne pepper without letting pure heat dominate the dish.
Common Mistakes When Evaluating Hot Sauce Heat
Many home cooks assume that a pepper's raw Scoville rating directly dictates the sauce's final spice level. This assumption causes frequent confusion in the kitchen.
- Ignoring dilution ratios: A sauce made from a super-hot habanero or ghost pepper can still test mild if the manufacturer dilutes it heavily with tomato paste, carrots, or fruit purees.
- Confusing tang with heat: High acidity from heavy vinegar content creates a sharp sensation on the tongue and throat, which people often misinterpret as intense capsaicin burn.
- Overlooking aging processes: Fermenting or aging peppers breaks down sugars and alters capsaicin stability, changing the perceived punch of the final product.
Frequently Asked Questions
Is Frank's RedHot considered a spicy hot sauce?
By modern standards, no. At 450 SHU, it is classified as a mild condiment. It focuses on savory flavor enhancement rather than burning heat.
Why is the original recipe so much milder than raw cayenne peppers?
Raw cayenne peppers register between 30,000 and 50,000 SHU. When manufacturers blend those peppers with large amounts of vinegar and water, the capsaicin gets heavily diluted.
Does the XTRA Hot version use a different pepper?
No, the extra hot version uses the same core cayenne pepper variety as the original. The manufacturer simply increases the pepper-to-liquid ratio to ramp up the capsaicin concentration.
Can I use Frank's RedHot in recipes if I have a low spice tolerance?
Yes. Because the heat level is so low, most people tolerate it easily, especially when it's mixed into butter, dressings, or marinades for wings and dips. You can check out more culinary ideas directly on the Frank's RedHot Official Website.
