Here is an interesting tidbit of a WVO observation.  Mid summer, I put a sample of oil that I ran through the centrifuge next to a sample of oil that I had not.  Both samples where “clear” but you could see particles in the pre centrifuged sample and it had a darker look.  Both of these sample came from the same source restaurant.  Average temperature was mid to high 80s.

The interesting part is when I looked at the samples recently.  Now November, the average temperature is high 50s or so and you can see that both samples have started to solidify but the un-centrifuged oil has solidified much more.  I am interested to hear some theories out there but my thought is it a “snow flake” effect where the solidification or crystals start with a piece of contamination.  Either way, it would appear that now coming into winter, a small amount of contamination could be a much larger problem than it was in the summer.
