Meaning

Waters and liquors pressed from plants are said to acquire mould and mildew as though a skin formed over them. Pellis is a comparison for the surface layer, not a claim that the liquid grows literal animal skin. The oil-covering argument then claims protection against this visible corruption. The image explains the problem the text aims to solve without making absence of a skinlike layer a reliable guarantee of safety.
