As a material, leather doesn’t seem to have scent producing qualities such as food or flowers. Yet, it’s still able to produce a rich and recognizable scent?
The reason why leather smells so rich comes more down to how it was tanned and less than from the leather intrinsically.

Many skilled leathercrafters prefer to stitch by hand. This isn’t because we’re stubborn traditionalists who refuse to use machines . . . although there is a sense of pride involved in hand-stitching, admittedly. Instead, we hand-stitch because it directly contributes to the durability and appearance of the product.
