There are different types of chorizo though, including semi fresh/dried versions that definitely require refrigeration, or you'll quickly be a sick puppy. The fresher ones are generally better for cooking, as they give out more that beautifully tasty paprika oil.
Jefe's one sounds like a dried chorizo. If it's got a thick (remove before eating) skin and the texture of a salami it'll generally be ok strung up a coolish, preferably dark place. A fridge isn't a bad place for them too tbh.
