This big bottle of spicy hot ketchup from Spain says it only lasts 1 month in the fridge after opening. Is the label lying?

• If yes, then an asshole designed the label.
• If no, then the ketchup is a crappy design because a family must be large and has to eat burgers, fries, and meatloaf every day to get through 560g.

Ketchup on the US market would be loaded with sugar and preservatives. But Europe and maybe the rest of the world is more inclined to have a higher proportion of pronounceable ingredients and fewer of them.

There is sriracha ketchup in the US which is shelf stable even after opening. Hot spicy foods are often that way, so apparently there is enough sriracha in that ketchup to keep it stable without refrigeration. Yet the cayanne pepper spiked ketchup from Spain is said to struggle to hold up even when refrigerated.
