Okay, I checked it this morning after being in the fridge all night. The viscosity may have gotten slightly thicker but it didn’t solidify or congeal. So according to the fridge test, this would be a bottle of fake EVOO.
That said, the fridge test seems to be a myth:

Ok, that “could” be a myth busted, but I am not certain I would trust an immediate source that had a vested interest in the contents of said test.
Seed oils and canola etc have different fatty acid responses at lower temps so there could still be adulteration but if the consistency is something like soft butter it may just take a little longer. Or it could have had the waxes removed and been ‘winterized’ for consistency (salad dressings). Dr. Gundry needs to do another Youtube ad. :)
