I want to give them the benefit of the doubt and say perhaps it’s a deep freezer that is only opened occasionally, and I guess is pretty well sealed as long as it’s closed.
The kitchen appears to have one of those built-in fridges that matches the cabinets:
Showerbeers
I like the way you think, also, that thing is enough for the whole family to have showerbeers, or they live really remote and need 3 months supplies.
