Quick Answer
What are the ingredients in Frank's RedHot Original?Frank's RedHot Original contains six ingredients: distilled vinegar, aged cayenne red peppers, water, salt, garlic powder, and natural flavor. The simplicity is what makes it work — high-quality aged cayenne peppers provide the pepper character, distilled white vinegar provides the sharp tang, and salt ties it together. There are no thickeners, no artificial colors (the orange-red comes from natural carotenoids in the peppers), and no sugar. This clean formula is why Frank's became the standard base for buffalo sauce.
The Full Ingredient List
Frank's RedHot Original (per current label):
- Distilled Vinegar
- Aged Cayenne Red Peppers
- Water
- Salt
- Garlic Powder
- Natural Flavor
That's it. Six ingredients. The simplicity is intentional and is a large part of what makes Frank's useful as both a standalone condiment and as the base for homemade buffalo sauce.
Frank's RedHot Ingredients: Function Breakdown
| Ingredient | Function | Why It Matters |
|---|---|---|
| Distilled vinegar | Acidifier, preservative, tang carrier | Provides sharp, clean brightness; preserves shelf life |
| ★ Aged cayenne red peppers | Heat, flavor, color | The core ingredient; aging develops complexity |
| Water | Carrier, dilution control | Adjusts viscosity and pepper concentration |
| Salt | Flavor amplifier | Standard flavor enhancer; increases perceived heat |
| Garlic powder | Background flavor | Adds savory depth without being identifiable |
| Natural flavor | Flavor rounding | Proprietary; likely vinegar-derived or pepper extract |
Aged Cayenne Red Peppers: The Core Ingredient
The most important word in "aged cayenne red peppers" is aged. Frank's doesn't use fresh cayenne. The peppers are aged — typically in salt brine for an extended period — before being processed into the sauce. Aging does several things:
- Develops fermentation flavors: Aged peppers develop a slightly fermented depth that fresh peppers lack. This is similar to the aging process in Tabasco (which ages for 3 years in oak barrels) but less extreme.
- Breaks down cell walls: Aging softens the pepper, making it easier to process into a smooth sauce.
- Concentrates capsaicin: The aging process concentrates the capsaicinoids relative to the water content of the fresh pepper.
- Creates color stability: The orange-red color from aged cayenne is more stable and intense than fresh cayenne.
Cayenne peppers (Capsicum annuum) range from 30,000–50,000 SHU before processing. The final Frank's sauce lands at approximately 450–1,000 SHU at bottle strength — the dilution with vinegar and water significantly reduces the heat concentration.

Distilled Vinegar: First Ingredient, Maximum Influence
Ingredients on US food labels are listed in order of weight — most to least. Distilled vinegar is the first ingredient in Frank's, meaning it's the most abundant ingredient by weight. This makes sense: Frank's is approximately 60–70% vinegar by volume.
Why distilled white vinegar (as opposed to apple cider vinegar, red wine vinegar, or others)?
- Clean flavor: Distilled white vinegar has an extremely clean, neutral-base acid taste — it doesn't add secondary flavors that would compete with the peppers.
- Consistent acidity: Distilled vinegar is standardized to 5% acidity, making it predictable batch to batch.
- Color neutrality: Unlike apple cider vinegar (slightly golden) or balsamic (dark brown), distilled vinegar is clear and doesn't alter the sauce's red-orange color.
- Preservation: The acetic acid in vinegar creates an inhospitable environment for microbial growth, giving the sauce its long shelf life.
Water and Salt
Water dilutes the sauce to working viscosity and adjusts the pepper and vinegar concentration. The pepper mash from aged cayennes is thick — water brings it to pourable consistency.
Salt in Frank's serves two purposes: flavor amplification (salt increases our perception of other flavors, including capsaicin's heat) and preservation (salt reduces water activity, inhibiting microbial growth). Frank's has approximately 190mg sodium per teaspoon serving.
Garlic Powder and Natural Flavor
Garlic powder: Added in small quantity. You can't taste garlic distinctly in Frank's, but its absence would make the sauce taste flatter. Garlic powder contributes savory depth (glutamate content) and rounds the sharp vinegar-pepper edge.
Natural flavor: The most opaque ingredient. "Natural flavor" is an FDA-defined category that includes any flavor compound derived from natural sources (plants, animals, fermentation products). In hot sauces, natural flavors are typically vinegar-derived flavor compounds or minor pepper extract additions. McCormick (Frank's parent company) doesn't disclose what the natural flavor is specifically — it's considered proprietary.
💡 Replicating Frank's at Home
If you want to replicate Frank's RedHot from scratch: aged cayenne pepper mash (or fresh cayenne + long vinegar maceration), distilled white vinegar, water, salt, and garlic powder. The key variable is the aged peppers — if you use fresh cayenne, the sauce will taste different (brighter, less complex). Short-cut: use fresh cayenne peppers + a splash of Worcestershire sauce (which provides fermented depth similar to aged pepper mash). See the full guide at buffalo sauce from scratch.
