[ashwlfbv] Black pepper density

I saw today at McKinnons two identically sized bottles of black pepper. The bottle of ground pepper was marked 1.5 oz and the bottle of unground peppercorns were 1.75 oz and felt noticeably heavier.

How can this be? You would think that after grinding, the black pepper flakes would be able to pack more densely than the unground spherical peppercorns.

Many possibilities: Due to many sharp edges after grinding, the ground flakes pack worse than peppercorns despite being smaller. The ground pepper is made of a lower density peppercorn than what was in the other bottle. The ground pepper contains some low density filler (lawsuit!).
