The best quality leather is known as Full Grain. This is the top split of the leather (also known as the hair split) but where no buffing, sanding or correcting has taken place. The Full Grain then can be pigment coated or aniline dyed. This will always be the softest and best quality leather, it will also be the most expensive. Cheaper quality leather comes from the top split but has been sanded or buffed (corrected) to remove imperfections and then pigment coated or finished. This will always be a lower quality product but can be hard wearing.
An Aniline style leather will be absorbent and a pigment coated leather is not so the easiest way to tell is to put a bit of water on the leather and see whether it soaks in or sits on the surface.
