FAQ
Common questions
Do I need a pH meter to make hot sauce?
For fresh sauces stored in the fridge and used within a few weeks, no. For fermented or vinegar-based sauces you plan to store at room temperature, yes — pH 4.6 or below is the food safety threshold. A $15-40 meter is the right tool; strips aren't precise enough.
What's the difference between fermented and fresh hot sauce?
Fresh sauce is blended raw or cooked peppers with vinegar, salt, and seasonings — simple, fast, and tangy from the vinegar. Fermented sauce uses lactic acid bacteria (the same organisms in sauerkraut) to acidify peppers naturally over days or weeks, producing complex, funky flavor that vinegar can't replicate. Most classic hot sauces — including Tabasco — are fermented.
What peppers should I start with?
Jalapeños and serranos are forgiving, available year-round, and relatively mild — perfect for learning the process. Fresno chiles make excellent fermented red sauce. Habaneros taste incredible but punish small mistakes with intense heat — save those for after you've nailed the technique with milder peppers.
How long does homemade hot sauce last?
Properly acidified fermented sauce (pH ≤ 4.6) in woozy bottles is shelf-stable at room temperature for 6-12 months. Once opened, refrigerate and use within a month or two. Fresh blended sauces without fermentation need refrigeration and last 2-4 weeks.
Why does my ferment smell weird?
Funky, yeasty, and slightly sulfurous is normal and often great — that's active fermentation. Strong mold smell, pink or black fuzz on the surface, or slimy texture means something went wrong. The usual culprit is peppers floating above the brine and oxidizing. Keep them submerged and most problems don't start.
Can I make hot sauce without fermenting?
Absolutely — a roasted pepper sauce blended with apple cider vinegar, garlic, and salt takes 30 minutes and is legitimately delicious. Frank's RedHot and Crystal are vinegar-forward sauces made without wild fermentation. Start there if fermentation feels like too much to tackle first.
