The rooster brand sriracha that is ubiquitous has always been very acidic to me. Real Thai sriracha should balance heat, sweet and sour. This is my version and is fermented like the original Thai-style sriracha. Make sure the bowl or container that you are fermenting in is sterile or you could ruin the fermentation. I like to rinse the bowl with boiling water and allow it to air dry before fermenting.
