ELI5: How do Commercial Hot Sauces Control the Heat in Every Bottle, Despite Peppers Varying Greatly in Their Intensity?

You can bite into one jalapeno and have it taste essentially like a bell pepper, and then bite into another and experience burning hellfire. How do companies that use peppers in their sauces keep uniformity throughout every bottle despite this natural variation?

I used to work in a lab that tested hot sauce, amongst other things. You can determine how spicy it is by chemical analysis, specifically HPLC, if you are interested. USP has a capsaicin method that is used to determine how spicy something is.
