To clarify (!) matters, no it's not air bubbles. It looks kind of like 
the chalky stuff that you get when you drop a fizzy tablet into water - 
except not as coarse and chalky and there are no bubbles drifting to the 
surface. It just kind of appears gradually on the top, swirling around.

Anyway, I've decided to drink apple juice now.
