Hey everyone! 👋

I've been making hot sauces at home for years with my wife (she is the hot pepper grower), and one thing that always bugged me was not knowing the actual (estimated) Scoville rating of my creations. I'd mix morugas with habaneros and have no clue if I just made something mild or face-melting.

So after countless revisions (seriously, I've lost count), I finally built a free Scoville calculator that I'm ready to share: https://gombaichili.hu/hot-sauce-shu-calculator/

How it works:

  1. Enter your base sauce amount (grams or cups)
  2. Add each pepper type and quantity from the dropdown
  3. Get instant results: Min/Avg/Max SHU + heat category

It factors in the natural Scoville range of each pepper (since even jalapeños vary wildly) and gives you a realistic estimate. Way better than guessing!

Current peppers available:

  • Jalapeño
  • Lemon Drop
  • Cayenne
  • Bird's Eye
  • Scotch Bonnet
  • Red & Yellow Habanero
  • Chocolate Habanero
  • Ghost Pepper
  • Big Mustard Mama
  • Trinidad Moruga Scorpion
  • Carolina Reaper

Fair warning: This is v1.0 after tons of revisions. Works great on desktop, and mobile is about 85% there. If you find any issues (especially on mobile), I'd really appreciate hearing about them!

Also:

  • Completely free, no signup
  • Perfect for recipe development and sauce labeling ("Estimated" is an important word!)

What I'd love feedback on:

  • Missing peppers you'd like to see added (I'll need min/max SHU + a reference link to verify)
  • Any bugs or layout issues (especially mobile)
  • Feature requests
  • Whether the SHU calculations seem accurate to your experience

Thanks for checking it out!

    Hey, thanks for checking it out! Quick context: This is genuinely v1.0 after I rebuilt it multiple times trying to get the math right and the UX decent. I’m a hot sauce maker first, “programmer” second, so any feedback is super helpful.

    The 11 peppers are the ones I use most and have verified SHU ranges for. If you want others added, I’d love suggestions – just need the pepper name, min/max SHU, and a reference link so I can verify the data before adding it. Keeps the calculator accurate!

    Mobile is my next focus – if you spot anything wonky, please let me know what device/browser you’re using!

    Nice, I rarely use hot sauces and only in very small amounts, but I played around with this calculator for a while. 😀
