shark sriracha is a brand of sriracha actually made in Thailand - no additives, only peppers, salt,water, garlic,sugar and vinegar,
the more common/avaialable "Rooster" Sriracha @ Walmart, etc. is made in California(lots of additives - potassium sorbate, sodium bisulfite, xantham gum). even with all the additives/preservatives I have a bottle in the fridge.
