I know this is barrel strength and unfiltered, but after I bought the bottle and had a look at it in the sun, I noticed white flakes all through out. I can see the cork and it looks intact and I don't see any dark mold-like spots. These flakes aren't the normal looking broad and flat, they are more stringy.

Is this the oils/fats that have cooled or is this some sort of cork flake that has come off?
