Hot Sauce and the pH Standard
Traditional Louisiana-style hot sauce — peppers, vinegar, salt — easily achieves pH below 4.6, the threshold for high-acid shelf-stable food. This makes vinegar-based hot sauce one of the more accessible cottage food products for those interested in condiment sales.
What Qualifies
- Vinegar-based hot sauce (Louisiana-style, Tabasco-style) with pH below 4.6
- Dried hot spice blends and chile powders (no acidification needed — shelf-stable dry products)
- Pepper jelly (high-sugar, high-acid — treated like jam)
What Does Not Qualify
- Fresh salsa and pico de gallo (requires refrigeration)
- Fermented hot sauce without added acid (variable pH, may not reach 4.6)
- Any sauce marketed as "keep refrigerated"
pH Testing Is Essential
If you produce hot sauce to sell, measure pH for every batch with a calibrated pH meter. Keep records. An inexpensive digital pH meter costs under $30 and confirms your product is safely below 4.6. This is both a safety practice and evidence of compliance if your products are ever questioned.
Labeling Hot Sauce
Include all standard cottage food label fields plus the heat level (mild/medium/hot) as a consumer service. Declare any major allergens. Some hot sauce makers use vinegar with sulfites or other additives — check ingredient suppliers for allergen statements.
