In this case its literally just the geographical location of the factory that made it. I usually get the Aldi version of things where they just change the name slightly but it is otherwise the same thing.

Shame my local Aldi stopped selling grilling cheese as an alternative to halloumi though, its quite a lot cheaper and avoids having to transport food across Europe unnecessarily. If I wanted high quality I wouldn't go for genuine halloumi either, there is a somewhat local farm that sells their own halloumi style cheese which legally isn't halloumi but tastes way better than anything supermarkets sell that can legally be called halloumi.
